If you are reading this late at night after being released from a Garda station, you may be frightened about losing your licence, your job and your good name. You may also be replaying every part of the arrest in your head.
That reaction is more common than you think.
People go home, stare at the ceiling and convince themselves that one bad night has changed who they are. It has not.
You are not the charge on a page and you are not the worst five minutes of your life.
The first thing to understand is this: an arrest, a reading or an MBRS certificate is not the same thing as a conviction. Equally, nobody should promise that a case will disappear because of a supposed ‘technicality’. The evidence and the law have to be examined carefully from the beginning.
This guide explains that process from the roadside to the final outcome. It separates breath, blood, urine and hospital cases because they do not all follow the same evidential route.
In brief…
In Ireland, it is an offence to drive or attempt to drive in a public place while incapable of properly controlling a vehicle because of an intoxicant. It is also an offence to drive or attempt to drive with alcohol above the statutory limit.
A separate offence can arise where a person is in charge of a vehicle with intent to drive.
Most cases begin with a roadside breath test, followed by arrest and an evidential procedure at a Garda station. The final evidence may be:
an evidential breath statement from an EvidenzerIRL machine;
an MBRS certificate following analysis of blood; or
an MBRS certificate following analysis of urine.
Some lower readings can be dealt with by a fixed penalty notice. More on that later.
Other cases go to the District Court. A conviction can bring a fine, a criminal conviction and a mandatory driving disqualification. The length of the ban depends on the offence, the reading and previous relevant convictions.
The prosecution must prove the charge beyond reasonable doubt. That involves more than arguing that you were stopped driving and that at this time you were over the limit. The court will have to consider the driving, the public place, the legal basis for the Garda requirements, the specimen procedure, the legal documents, the integrity of the evidence and any defence your lawyer raises.
There is another reality that deserves to be said plainly. The law may be the same, but the human being applying it is not. Judges do not all assess evidence, credibility or legal arguments in exactly the same way.
An argument that troubles one judge may carry little weight with another. Knowing the court and understanding how to present the important evidence to the particular judge hearing the case, can sometimes make a real difference.
If this has happened to you, retain any paperwork given you and write down what occurred while it is fresh.
Read that again, as this is by far the most critically important thing you can do.
This document is long and if you take away nothing else from it take away this: write what happened and what was said, in great, from start to finish, on the day or evening of your arrest.
Do that now.
The longer you leave it the greater the chance that you will forget something valuable over time. This is because these cases can often take more than a year to conclude. In the space of a year its hard to remember what happened 12 months ago so get writing now.
Do not try to assess your case from a checklist online.

Frequently asked questions
1. What offences are commonly called drink driving?
Are there 'typical' drink driving cases?
“Drink driving” is a convenient phrase, but it covers several different allegations.
Driving or attempting to drive while incapable of proper control
Section 4(1) of the Road Traffic Act 2010 concerns a person who drives or attempts to drive while under the influence of an intoxicant to such an extent as to be incapable of having proper control of the vehicle.
This is an impairment offence. It is not confined to a prosecution based on a particular alcohol number. Evidence about driving, behaviour, speech, balance, admissions, Garda observations and medical examination may become relevant.
Driving or attempting to drive above the alcohol limit
Sections 4(2), 4(3) and 4(4) deal with the concentration of alcohol in blood, urine or breath. The question is whether the legal concentration is exceeded within three hours after the driving or attempted driving.
That does not mean that every procedural event must occur within three hours. The legal wording and the evidence in the individual case have to be considered carefully.
Being in charge with intent to drive
Section 5 creates related offences where a person is in charge of a vehicle in a public place with intent to drive or attempt to drive. The same alcohol limits apply. The section includes a presumption of an intention to drive until the contrary is shown.
What this means in plain English is that if you are arrested for being drunk in charge the law presumes you intended to drive until you show to the contrary. This is what’s known as a ‘reverse burden of proof’ i.e. the onus is on you to prove some element of your defence.
Someone found asleep in a parked car is not automatically guilty and is not automatically safe from prosecution.
The location, keys, vehicle, surrounding facts and evidence concerning intention -if it exists- matter greatly.
Refusing or failing to provide a specimen
A refusal or failure to comply with a lawful requirement is a separate offence. It carries a minimum disqualification that is more severe (4 years) than the maximum ban for a very high alcohol reading (3 years).
Refusing to provide a specimen (in the absence of a documented medical condition or procedural irregularity) is disastrous.
There are limited statutory protections and defences, including medical considerations in the appropriate case. “I did not want to provide it” is not a defence.
The current text of the principal provisions can be read in sections 4 and 5 of the Road Traffic Act 2010.
2. What are the drink-driving limits in Ireland?
The limits depend on whether the person is an ordinary driver or a “specified person”.
Specimen | Ordinary driver | Specified person |
Blood | 50 mg alcohol per 100 ml blood/ | 20 mg per 100 ml |
Urine | 67 mg alcohol per 100 ml urine/ | 27 mg per 100 ml |
Breath | 22 microgrammes alcohol per 100 ml breath/ | 9 microgrammes per 100 ml |
These are legal limits, not targets.
There is no reliable formula saying that a particular number of drinks will keep a particular person below the limit. Body composition, food, timing, drink strength, metabolism and the period since drinking all vary.
“I felt fine” is not an answer to an excess-alcohol charge. A person may feel normal and still be over the legal limit.
However, if in doubt, consult the government website www.drinkaware.ie
Drink Aware give approximate times it takes for specific alcohol (beer, wine, whiskey, spirits etc) to leave the body.
Again, these are approximate guidelines: they are not scientific facts.
Can I be over the limit the next morning?
Yes. Sleep, coffee, food, a shower and fresh air do not remove alcohol from the body on demand. If alcohol remains above the statutory limit when you drive the following morning, a prosecution can follow.
The only thing that achieves the goal of removing alcohol from your system, according to the Medical Bureau of Road Safety, is time.
The longer the time since your last drink, the less alcohol remains.
3. Who is a specified person?
The law recognises a class of drivers whom it defines as “specified drivers”. They are subject to lower alcohol limits.
The lower limits apply to a person who, at the time of the alleged offence:
holds a learner permit for the relevant vehicle category,
is within the first two years of a first driving licence for that category,
is driving, attempting to drive or in charge of certain truck, bus, trailer or tractor categories identified in the legislation,
is driving a small public service vehicle in the course of business, including a taxi in the relevant circumstances,
purports to act as such a small public service vehicle driver while carrying persons for reward,
does not hold a licence for the relevant category, or
does not have their licence with them when demanded by a Garda.
The precise statutory definition is in section 3 of the Road Traffic Act 2010. The category being driven and the status of the licence should be checked rather than assumed.
4. What happens in a drink-driving case from start to finish?
No two cases are identical, but this is the usual sequence.
Stage 1: The vehicle is stopped or Gardaí attend an incident
A Garda may encounter a driver at an authorised mandatory testing checkpoint. A vehicle may also be stopped in another lawful setting, or Gardaí may arrive following a collision, alleged traffic offence or report from another person.
At a Mandatory Intoxilyser (MIT) Checkpoint, an authorisation must be made in writing by a Garda not below the rank of inspector and specify the place, date and hours. Section 10 permits Gardaí operating the checkpoint to stop vehicles and make preliminary breath requirements.
Outside a checkpoint, section 9 gives preliminary testing powers in defined circumstances. Depending on the subsection, those include a Garda forming an opinion that a person has consumed an intoxicant, an alleged road traffic offence, a collision or an event involving injury.
If you break the law in any way (e.g. speeding, holding a mobile phone, driving while unaccompanied, no NCT etc) a specimen of your breath or saliva (or both) can be required of you.
In other words, where you break the law while driving, this triggers a power to demand a specimen, whether or not the Garda can detect any alcohol from you.
So it’s more important than ever (especially for younger male drivers) to not break the law while driving. If you do, if you commit even some minor road traffic offence, this is the ‘excuse’ the Garda needs to stop you and subject you to testing.
The current provisions are set out in sections 9 and 10 of the 2010 Act.
Stage 2: A preliminary roadside breath test may be required
The handheld roadside device (Drager Alcotest 7510) is a screening device. It is not the same as the breath-testing apparatus used at a Garda station.
The Medical Bureau of Road Safety reports that the Dräger Alcotest 7510 is used for preliminary roadside alcohol testing and that instruments in operational use are calibrated twice each year.
A roadside positive indication of alcohol on your breath provides the basis for the next step (i.e. arrest), but the prosecution evidence in an excess-alcohol case will come from the later breath, blood or urine test in the station.
A refusal or failure at the roadside can itself have legal consequences. If you fail to provide at the roadside you will definitely be arrested.
Stage 3: Arrest
Where the legal conditions are met, and a person fails the roadside test, they will be arrested. This is certain. The person is then brought to a Garda station for an evidential procedure.
Write down the words used, the approximate times, the location, the Garda station and anything unusual. Do not embellish. A contemporaneous, honest account is far more useful than a reconstructed story months later. It is also much more accurate. But make sure you do it.
It’s important to understand that the roadside Drager test is only designed to help a Garda form their opinion that necessary grounds exist to arrest the person for drink driving.
But they don’t need to use the Drager device to arrest someone.
Often, due to slurred speech, strong smell of alcohol or some form of stumbling or unsteadiness, it is manifestly obvious that the person is drunk.
A Drager test is then largely pointless and they will be arrested without using it.
Stage 4: Arrival at the Garda station
You will ordinarily be introduced to the member in charge. That Garda has responsibility for the proper operation of the custody area and the welfare of people detained there. You should be informed why you are in custody and told about your rights.
You can ask to contact a solicitor. However, do not assume that asking for a solicitor suspends a lawful specimen requirement indefinitely. Gardai will proceed even if you’ve failed to get through to your solicitor or are waiting for them to call back.
Time does not stand still.
And what exactly is the point of talking to your solicitor anyway?
To get advice?
Fine. But the only advice that your solicitor could possibly give you would be to comply with the requirements and allow a specimen to be taken.
That is because you must comply because if the solicitor told you otherwise, they would be encouraging you to break the law.
You must not refuse to provide a specimen. You are legally required to give one. A refusal while waiting for a telephone call can create a separate and more serious problem.
Cooperate with lawful requirements and obtain advice as soon as it is available, either then or, more commonly, later.
The station procedure matters. The Garda may require:
two specimens of breath from the Evidenser machine, or
a specimen of blood or, at the person’s option, urine.
or both.
Section 12 regulates those requirements. The available route is not simply a free personal choice between breath, blood and urine in every case.
If a blood or urine requirement is made, you can choose to allow a doctor or nurse take a blood specimen from you or you can opt to provide urine. You do have a choice between both.
But if the Garda decides (and they are the ones who decide, not you) that you will have to provide two breath specimens, then that is what you must do. You cannot demand to give blood or urine instead.
5: The breath route
You will be required to provide two breath specimens into an EvidenzerIRL machine. Subject to the legal procedure, the lower of the two readings is used. Two identical statements are produced.
These are signed by the Garda and then handed to you. You will be asked to acknowledge receipt by signing both and returning one.
Refusing to sign does not make the evidence disappear. Section 13 expressly addresses a failure to sign.
6: The blood or urine route
A designated doctor or nurse takes blood or receives urine. The specimen is divided into two containers. Both are sealed.
The Garda must offer you one of the two sealed specimens and explain that either one may be retained. The remaining specimen is sent to the Medical Bureau of Road Safety.
If you decline to take a specimen, both are sealed in the MBRS box and sent to the Bureau. A retained specimen can be independently analysed. It should be stored and handled promptly on expert advice.
The division, offer and forwarding procedure appears in section 15 of the 2010 Act.
8: Release
Many people are released without knowing the final outcome. A breath case may already have produced a statement. In a blood or urine case, the MBRS analysis follows later.
Release without a charge is not a dismissal. It means that the investigation and paperwork continues and you will receive a summons at some future point.
Sometimes Gardaí return a person’s car keys on release.
That does not mean they have decided the person was sober, that the case has ended or that they somehow not fit to drive. It simply means the keys have been returned as they form part of your property.
Whether the person is then safe to drive is a separate question. Do not drive. You should arrange another way home. You do not want to end up like some of my clients: arrested twice on the same night for drink driving.
Statement, certificate, fixed penalty notice or summons
Depending on the route and reading, the person may later receive:
the evidential breath statement,
a copy of the MBRS analysis certificate,
a fixed penalty notice for an eligible lower reading, and/or
a District Court charge sheet.
Keep every document. Record the date of receipt. Do not write on an original certificate or notice.
Court preparation
If a summons issues, it will indicate when and where you have to appear in court i.e. what court and what date. It will also indicate the time you have to be there.
Not much will happen on that first appearance. The judge will note your appearance and will address your solicitor.
With that in mind you should have a solicitor representing you. They will do all the ‘talking’ on your behalf. You will not be asked to say anything. That is what your solicitor is there for.
This first day in court is procedural only.
No evidence is heard from any witness on behalf of the State. The judge is only concerned that you are there.
Then the case is adjourned for a number of weeks, usually 4-6 weeks, and an ‘order for disclosure’ is made. Here the judge is directing that all of the Garda evidence (i.e. statements, documents, reports) and anything else that the State intends to rely on is disclosed to your solicitor.
Between that first appearance in court and the second date, the disclosure should have arrived and both you are your solicitor should have had a chance to read it and assess it.
The disclosure in a drink driving case typically includes Garda statements, statutory forms, breath statements or MBRS certificates, custody records, checkpoint material, CCTV or medical evidence.
Not every item is relevant in every case. A proper review begins with the actual charge and evidential route.
District Court hearing
The prosecution must prove the case beyond reasonable doubt. Some cases resolve by plea of guilty. These might be cases where the arrested person was arrested for both a drink driving offence as well as something else e.g. dangerous driving or hit and run.
A note of caution: where you have collided into a third party while drunk and where this third party is a witness on behalf of the State, you need to take careful steps.
Barring some significant procedural error by the State, you not only run a very high risk of being found guilty, but also -if an injury occurred- the risk of jail, if you contest the charges and lose.
That is because of an inherent belief among judges that it is a good thing that people give evidence in court. It is part of our civic duty.
Judges also know that the justice system only works if witnesses turn up to court to give evidence.
They also know that the prospect of giving evidence causes deep anxiety among witnesses who have never been to court before and who may have had to take a day off work or pay for a childminder to look after their children.
Therefore judges have a great affinity towards witnesses who are ‘innocently’ dragged into a prosecution case through no fault of their own.
They are also far less likely to acquit a motorist who collided into a civilian witness than one who crashed into a ditch or where no one else was involved.
_________
Other cases proceed to a contested hearing in which witnesses give evidence and are cross-examined.
An acquittal may follow because an essential element was not proved, admissible evidence was insufficient, a legal requirement was not met or a substantive defence was established.
It should never be described as guaranteed.
Outcome, appeal or restoration
Following conviction, the court may impose a fine and must apply the relevant disqualification provisions. A District Court conviction can generally be appealed to the Circuit Court by way of a full rehearing. The time limit is 14 days.
A properly lodged appeal with the required recognisance (bail monies) can suspend a disqualification pending the appeal. If you don’t appeal within the 14 day period you will be disqualified.
In a limited class of longer disqualifications, an application for early restoration may eventually be possible. This is explained below.
How does the evidential breath procedure work?
Ireland uses the EvidenzerIRL for evidential breath testing at Garda stations. It is different from the preliminary handheld device used at the roadside.
According to the MBRS Annual Report 2025, 86 EvidenzerIRL instruments were supported nationally during 2025. There were 3,257 evidential breath cases. About 85% resulted in a successful procedure with a section 13 statement (i.e. paper printout of the breath reading in the Garda Station), while about 12% involved failure or refusal.
In roughly 3% of cases, the instrument’s safeguards meant that no statement issued, for example because of detected mouth alcohol or an unacceptable difference between breath specimens.
Which breath reading counts?
Section 13 provides for the lower of the two determined concentrations to be included in the statements. The machine historically applies an operational deduction. In DPP v Flanagan, the raw lower reading was 81 microgrammes per 100 millilitres and the statement recorded 66 after a 17.5% reduction. Quite why a ‘reduction’ of any amount is applied at all has not been explained to date.
How are blood and urine specimens analysed?
The MBRS receives the State’s sealed specimen and analyses it. It then forwards a completed certificate to the relevant Garda station and a copy to the person named on the statutory form.
The 2025 MBRS report records that:
6,087 blood and urine specimens were received for intoxicant analysis,
approximately 85% were blood and 15% were urine,
alcohol analysis used headspace gas chromatography with flame ionisation detection,
each alcohol specimen was analysed at least twice by different scientists on two systems, with results required to agree within the Bureau’s stated tolerance, and
29 specimens could not receive an alcohol certificate, including cases involving an unsealed container or insufficient specimen.
These statistics do not prove or disprove an individual case. They explain the system that produced the certificate. The individual documentation and evidence must still be examined.
Why does the retained specimen matter?
The retained specimen gives the person an opportunity to arrange independent analysis. It is not something to leave in a car or on a kitchen counter while deciding what to do. Seek immediate advice about suitable storage, transport and an accredited laboratory.
Quite honestly I don’t ever advise clients to prioritise getting these specimens examined. This is because the testing regime in the MBRS is internationally accredited and there has not been any reported cases to question their scientific analysis over the decades.
Additionally, the MBRS are the state-appointed laboratory. There is only one. This is in contrast to the UK and other jurisdictions where separate police forces use separate labs. Some of these labs have been shown not to have adhered to strict scientific chain of custody and testing regimen.
There has never been a hint that the Medical Bureau of Road Safety depart even slightly from approved scientific rectitude.
There is another reason why I trust the MBRS. While they analyse specimens on behalf of the State they do not work for the State.
This is a crucial distinction.
They are an independent body and on rare occasions have provided witnesses to give evidence on behalf of the Defence on issues such as how the MBRS conducts its work.
7. What happens in a hospital case?
Hospital cases follow a distinct statutory route and should not be treated as ordinary station cases.
Where an event involving a vehicle occurs in a public place and a person is injured, claims injury or appears injured and attends or is admitted to hospital, section 14 of the Road Traffic Act 2010 may apply. Subject to the statutory conditions, a Garda may require blood or, at the person’s option, urine.
The section also addresses a person who is medically incapable of complying and permits a direction to a designated doctor or nurse in defined circumstances.
The current procedure is contained in section 14 of the Road Traffic Act 2010.
I have acted in cases where a drink-driving prosecution was dismissed because the legal and procedural safeguards created by section 14 have not been adhered to. This demonstrates why the actual statutory route and medical evidence must be examined.
What happens after release?
Preserve the documents
As a general rule keep:
the breath statement or specimen paperwork,
any copy MBRS certificate,
the fixed penalty notice and envelope,
the summons and envelope,
hospital discharge records,
photographs, receipts or dashcam footage connected with the event; and
the details of anyone who witnessed relevant events.
How to construct a defence
“What would I see? What would I hear?”
Record approximate times for the last drink, driving, stop, roadside test, arrest, arrival at the station, each requirement, calls with a solicitor, specimen procedure and release. Mark estimates as estimates.
Also record what was said, both by the Garda to you and by you to the Garda. Words matter enormously in these cases.
Do not publish your account on social media. Do not contact witnesses to coordinate stories. Preserve evidence, then obtain advice.
If witnesses were there, ask them to record their own recollections of what happened but do not discuss the case with them. This is a form of collusion and is worthless from an evidentiary point of view. Besides, they may ultimately recall something you forgot and vice versa.
This element -creating your own written account- is critically important. As these cases frequently take many weeks or months to conclude, and as drivers had consumed alcohol (which impairs memory) the sooner you start to record in writing what happened on the night of your arrest the better.
You should write out what happened, from start to finish, during your interaction with the Gardai. This includes recording what the Gardai said to you, and what you said to them.
I appreciate that alcohol makes recollection difficult or often very hazy, but you must try. Remember, neither the judge nor your lawyer were there on the night of your arrest. You were.
This advice, to write everything down, is by far the most important piece of advice I can give you.
It is the first piece of advice I give every client who calls me. I cannot remember how many cases turned on a memory of something that a client disclosed to me, often many months after having first spoken to me.
These memories were often something that the client thought were too irrelevant or unimportant to mention to me. Many of them involved something the Garda had said, or had failed to say.
You don’t know what’s relevant so write everything down. Your solicitor will be able to pick out what could potentially be crucial to success.
As I say to all clients: “Describe the scene. Imagine I was standing there at the side of the road as you were interacting with the Gardai. What would I see? What would I hear?”
Do I still have a licence?
An arrest alone does not disqualify you. A fixed-charge disqualification begins in accordance with the statutory notice procedure.
A court disqualification comes into operation on the fifteenth day after it is made, unless it is suspended by an appeal.
What’s important to realise is that you are disqualified if the court finds you guilty. If the courts finds you not guilty you are obviously acquitted.
Just because you were over the limit when you drove does not mean that you will be convicted.
Exceeding the legal alcohol limit while driving are only two elements (you drove and were over the limit when you drove) that the State must prove in order to secure a conviction in a drink driving case.
But there are many others and these vary depending on the case.
9. Fixed penalty notices
Yes, you may be eligible for lower-range cases.
Ordinary drivers
Reading | Fixed charge | Disqualification |
Blood: over 50 up to 80 mg; urine: over 67 up to 107 mg; breath: over 22 up to 35 µg | €200 | 3 months |
Blood: over 80 up to 100 mg; urine: over 107 up to 135 mg; breath: over 35 up to 44 µg | €400 | 6 months |
Specified drivers
A specified driver with a reading above the lower specified-person limit but not exceeding 80 mg blood, 107 mg urine or 35 microgrammes breath may be eligible for a €200 fixed charge and three-month disqualification.
Eligibility is not based on the number alone. The legislation excludes, among others, a person who did not hold a valid licence or was already disqualified at the time, and a person who received a fixed charge notice in the previous 3 years. Payment is generally required within 28 days.
Paying the fixed charge avoids a prosecution for that offence but it does carry a disqualification.
The critically important aspect of a fixed charge notice is this: paying it and going off the road for 3 or 6 months is not regarded as a conviction.
So, you can be disqualified from driving and not receive a conviction.
This lack of a conviction has massive implications for your ability to get insurance again in the years ahead (many drivers who have been convicted of drink driving in court simply cannot get insurance afterwards) and in some cases, to travel.
The current bands and conditions are in section 29 of the Road Traffic Act 2010.
10. What must the prosecution prove?
The required proof depends on the charge. An excess-alcohol prosecution requires proof of matters including:
the defendant’s identity,
driving, attempting to drive, or being in charge with the required intent,
a mechanically propelled vehicle,
a public place,
the legal foundation for the relevant Garda power and requirement,
compliance with the applicable breath, blood, urine or hospital procedure,
the statutory statement or certificate and associated presumptions,
a concentration exceeding the applicable limit within the statutory framework, and
service and other procedural matters where they are put in issue.
For an impairment charge, evidence showing incapacity to control the vehicle properly becomes central. For a refusal charge, the requirement, communication, refusal or failure, and any statutory defence must be considered.
The law contains evidential presumptions.
A defence solicitor must therefore identify not only what the prosecution can or has proved but also what the legislation presumes unless evidence to the contrary is produced.
11. What Patrick Horan's Courts Service FOI figures show
I first asked the Courts Service for drink-driving and drug-driving outcome data in July 2024. I made a further request in September 2025 so that the figures could be brought up to date and supported by actual numbers.
The Courts Service granted that request in full on 13 October 2025 under reference FOI 155/25.
The response records convictions and non-convictions in drink-driving matters from 1 January 2020 to 30 August 2025. I calculated the national percentages from the counts in Appendix 1:
Period | Convictions | Non-convictions | Total recorded matters | Conviction rate | Non-conviction rate |
2020 | 2,538 | 1,389 | 3,927 | 64.63% | 35.37% |
2021 | 2,840 | 1,652 | 4,492 | 63.22% | 36.78% |
2022 | 2,893 | 1,888 | 4,781 | 60.51% | 39.49% |
2023 | 2,964 | 2,041 | 5,005 | 59.22% | 40.78% |
2024 | 2,801 | 2,139 | 4,940 | 56.70% | 43.30% |
1 January to 30 August 2025 | 1,747 | 1,366 | 3,113 | 56.12% | 43.88% |
Entire period | 15,783 | 10,475 | 26,258 | 60.11% | 39.89% |
“Non-conviction” is the category used in the Courts Service spreadsheet.
The data does not say that every non-conviction was an acquittal following a contested trial, and it does not break the category into dismissals, withdrawals, struck-out cases or other outcomes.
All the Courts Service could tell me was that a case either did or did not result in a conviction.
Why did Patrick Horan obtain these figures?
People regularly ask me whether anyone ever wins a drink-driving case.
General answers were being repeated online without a reliable source, so I asked the Courts Service directly.
Of course I already knew the answer to this question, but it was good to have definitive proof from a trusted source.
The updated response shows something important. A prosecution does not inevitably produce a conviction.
Across all 26,258 drink-driving cases recorded for the period, 39.89% were placed in the Courts Service non-conviction category.
In 2024 the figure was 43.30%. From 1 January to 30 August 2025 it was 43.88%.
That does not predict the outcome of your case. It tells us only that the legal process matters and that “charged” and “convicted” are not interchangeable words.
One thing is important to note. Roughly 40% of motorists were not convicted.
Every one of these motorists were over the limit when they were arrested driving, like you.
Why I am not publishing a league table of courts
The Courts Service appendix provides counts by court office and court area. I have deliberately aggregated the figures nationally rather than reproducing or ranking those offices.
A court-office percentage cannot fairly be attributed to an individual judge. The report does not identify which judge heard each case, the number or type of cases, how many matters were withdrawn, the evidence available or the reasons for individual outcomes. Judges also move between court areas.
Publishing a list of supposedly “soft” or “hard” courts would therefore encourage conclusions that the data cannot support. It could also place unfair pressure on judges because they decided cases on the evidence before them.
My experience remains that judges do not all assess evidence in the same way.
That is a professional observation drawn from appearing in court everywhere in Ireland, not a claim proved by these percentages.
The FOI figures are used here for one narrower purpose: to show that a prosecution and a conviction are not the same thing.
Everyone is prosecuted, but about 4 in 10 are not convicted.
Important limitations in the Courts Service data
The Courts Service states that it could provide data only where prosecutors used offence codes available on its system. Its particular warning about uncoded free-text offences concerns the drug-driving dataset, because no Garda offence code existed for some time. The response does not claim to measure every prosecution initiated, and it does not explain the legal or factual reason for each non-conviction.
The percentages above are my calculations from the Courts Service counts. They should be described as national rates calculated from coded matters recorded by the Courts Service, not as a scientifically complete measure of every drink-driving prosecution. They are still valuable because they came directly from the body administering the court records following a request made specifically for this information.

12. What possible defence issues arise in Irish drink-driving cases?
There is no universal list that decides a case. The headings below explain the legal territory. They are not instructions for manufacturing a defence.
Was there proof of driving, attempting to drive or being in charge?
Identity and driving may be observed directly, proved by admission or inferred – in rare instances- from evidence.
In other cases, the prosecution evidence may be disputed.
For instance, in the context of s drunk in charge prosecution, being near a vehicle is not the same as driving it. You may not be charged with drink driving but it might place you “in charge” of it. That could lead to a charge of being “drunk in charge”.
Then the question for the judge becomes:
“from the available evidence in this case can we say that the defendant in this particular case, and based on all the circumstances of this case, was in charge of the vehicle even though he was not seated inside it?”
As in all cases, the complete circumstances matter. Context is key.
This is what I mean when I use the (admittedly tired) phrase: no two cases are the same.
Was it a public place?
The legal definition and the evidence concerning access and use can matter. A place does not cease to be public merely because it is privately owned.
Under the road traffic acts a place may be privately owned but if the public have access to it and can drive into it, it may be regarded as a public place.
If it is, you can be arrested there for the purposes of drink driving.
Private property creates a different question.
Section 7 gives Gardaí defined powers to enter property for preliminary testing and arrest. In one case in which I acted, the court found that the implied permission to remain on a driveway had been withdrawn and the statutory authority relied upon had not been communicated.
The arrest and the later evidence could not simply be separated from this fundamental problem. The net effect was that the breach was captured by the ‘exclusionary rule’ which the High Court has defined as meaning that all evidence gathered in breach of the defendant’s rights is excluded.
This is highly fact-specific and does not mean that driving onto private property prevents arrest.
Was the Garda power lawfully exercised?
The legal basis may be an authorised checkpoint, a Garda opinion, an alleged road traffic offence, a collision or an injury event.
The roadside device also has operating instructions. In a case where the motorist admitted that he had just left a nearby pub, the court considered whether the Garda knew or had reason to suppose that alcohol had been consumed within the preceding twenty minutes.
The case was dismissed after the required observation issue was not proved. That does not create a twenty-minute defence in every case. It shows why the known facts and the instructions applying to the device matter.
Was the arrest lawful?
The court may need to consider the information available to the arresting Garda, the statutory power relied upon and the words and sequence proved in evidence.
The lawfulness of detention and the use of handcuffs may also arise where the evidence supports it. In separate cases in which I acted, courts dismissed prosecutions where the evidence did not establish the individual decision behind handcuffing or where issues arose as to the roadside detention. These outcomes should not be converted into a claim that handcuffing automatically invalidates a prosecution. It does not.
The Supreme Court in Pires, Corrigan and Gannon [2019] stated that the Gardai have “a measure of latitude” in the use of handcuffs.
Mrs Justice Dunne discouraged courts from “the use of hindsight to come to a view that the individual member of the Gardai concerned should have taken a different course”.
Was the station requirement made and communicated in accordance with law?
Breath, blood and urine routes have different requirements. The evidence may include the precise words used, responses, medical circumstances and statutory forms.
However, the precise wording is not conclusive in every case and generally only becomes crucial in instances where a person fails or refuses to provide a breath, blood or urine specimen.
Was the evidential breath procedure reliable in this case?
The statement, two specimens, instrument safeguards and available technical evidence may be relevant.
The 2026 Flanagan judgment confirms that, on appropriate evidence, a trial judge may permit defence inspection of an Evidenzer breath machine in the Garda station.
It does not grant automatic or unrestricted software access in every case.
Was blood or urine lawfully taken, divided, offered, sealed and forwarded?
Section 15 creates a structured specimen procedure.
It also creates a presumption i.e. the law presumes that the specimen was divided in two, sealed and forwarded to the Bureau as soon as practicable.
But, like every presumption, it is rebuttable. The issue is not whether a solicitor can spot a misspelling. It is whether admissible evidence proves the statutory process and whether any evidence capable of rebutting a presumption exists.
One of my cases concerned a motorist who chose blood.
A doctor tried twice but could not obtain enough. A urine requirement was then made, but the law that would have allowed a new demand for urine was not proven. The urine reading was 288mls.
The legal limit is 67mls. The prosecution was dismissed. Again, where a fundamental breach of the law had taken place, the court ruled that it invalidated the State’s case.
Was the hospital procedure followed?
Consultation with the doctor, health prejudice, medical capacity and the role of the designated practitioner may require close attention.
Was there post-driving alcohol consumption?
Sometimes called the “hip flask” issue, section 18 places a substantial evidential burden on the defence. Evidence of drinking after the alleged driving is disregarded unless the court is satisfied that, without that later consumption, the person would not have exceeded the applicable limit. Expert medical evidence is central.
Deliberately drinking after driving with the intention to frustrate a prosecution is itself an offence. The statutory provision is section 18 of the 2010 Act.
Was there a medical or other statutory defence to an alleged refusal?
A genuine inability to provide breath, or urine as the case may be, must be supported by medical evidence. The law distinguishes unwillingness from inability. The relevant statutory wording and medical evidence require careful treatment.
Can duress or necessity ever apply?
In exceptional circumstances, yes.
In a Galway case concerning Natalie Boland, our team, led by Colm Hennessy BL, advanced the defences of duress and necessity to a drink-driving prosecution. The case resulted in an acquittal. It illustrates that the law can recognise a person who drove in response to an immediate and compelling danger, but only where the evidence satisfies demanding legal tests.
Natalie had been staying in Salthill when, according to the evidence accepted by the court, she was assaulted by the man she was with. She grabbed her keys and fled. She drove for about one kilometre before recognising that she could not continue and turning back towards the hotel. When the Garda encountered her, she was hysterical. Her alcohol reading was nearly three times the ordinary limit.
Judge Brennan accepted that she had acted out of fear and that her short, proportionate journey mattered. He observed that the position would have been different had she continued a substantial distance. The case was not won because personal distress excuses drink driving. It was won because the particular evidence satisfied the legal requirements of duress and necessity.
Judge Brennan’s approach is also an example of why the identity of the trial judge matters. He listened to Natalie, assessed whether she was telling the truth, considered the distance she had driven and applied the law to those facts. Another judge might have attached different weight to one or more parts of the same evidence.
It does not mean that stress, inconvenience or a difficult personal situation automatically excuses drink driving. They never do.
13. Can a defence expert inspect the Evidenzer? DPP v PJ Flanagan
This is one of the most important recent Irish decisions concerning evidential breath testing.
In Director of Public Prosecutions v Patrick James Flanagan [2026] IEHC 531, delivered by Mr Justice Barr in the High Court on 31 July 2026, the DPP challenged an order made by the Circuit Court allowing a defence expert to inspect the Evidenzer used in the respondent’s case.
The underlying breath procedure took place after an arrest in Thurles on 2 May 2022. The lower raw reading was 81 microgrammes per 100 millilitres of breath. After the instrument’s 17.5% reduction, the statement recorded 66.
On appeal from the District Court, expert evidence was given by Dr Mark Jordan that inspection of hardware and software was necessary to assess the forensic integrity of the evidence. The MBRS accepted that some inspection could occur but disputed the proposed scope.
The High Court refused the DPP’s application for judicial review. It held, in substance, that the Circuit Court’s decision was open to it on the expert evidence. The judgment is important for three reasons:
An accused may seek inspection of an Evidenzer where a proper evidential foundation exists.
The scope of any inspection is a matter for the trial judge, applying judicial discretion to the evidence and circumstances.
The decision does not create an automatic right to every form of inspection in every breath case.
A responsible solicitor should not cite Flanagan as meaning that all breath prosecutions are now defective. Its importance is that meaningful inspection remains legally available where justified, despite the State’s challenge to the Circuit Court order having failed.
As of 28 August 2026, the High Court had refused the relief sought. The matter is listed for final orders and costs submissions on 9 October 2026. The State have 28 days after the Order has been perfected to decide whether they wish to appeal to the Supreme Court.
As of now, the State’s position on any further appeal may not be known until mid-November 2026.
For the background to the original Circuit Court order, read Patrick Horan’s Evidenzer inspection case note.
14. What does Ratinskis v DPP mean for chain-of-custody arguments?
In Ratinskis v Director of Public Prosecutions [2026] IESC 33, delivered on 11 June 2026, the Supreme Court addressed proof surrounding the handling of a blood specimen.
The Court affirmed the conviction.
The decision rejects the idea that every alleged gap in the handling history automatically defeats the statutory certificate or requires the prosecution to call every person who handled a package. Statutory presumptions have real legal effect.
The equally important qualification is that a presumption may be rebutted by evidence to the contrary. The task is therefore to identify admissible evidence, not merely to point to an unexplained interval and label it a broken chain.
The practical lesson is straightforward: chain-of-custody issues remain fact-sensitive, but post-Ratinskis they must be analysed through the precise statutory presumption and the evidence capable of displacing it.
15. What are the court penalties for drink driving?
The court can impose a fine of up to €5,000 and imprisonment for up to six months for the principal section 4 (drink driving) or section 5 (drunk in charge) offences. The mandatory disqualification is often the immediate concern.
For a first excess-alcohol offence under section 4(2), (3) or (4), the minimum disqualification bands are:
Alcohol concentration | Minimum disqualification |
Blood up to 80; urine up to 107; breath up to 35 | 3 months |
Blood over 80 to 100; urine over 107 to 135; breath over 35 to 44 | 6 months |
Blood over 100 to 150; urine over 135 to 200; breath over 44 to 66 | 2 years |
Blood over 150; urine over 200; breath over 66 | 3 years |
Relevant repeat convictions can increase those minimums to one, two, four or six years respectively.
What is the ban for being incapable of proper control?
A first conviction for the impairment offence under section 4(1) carries a minimum four-year disqualification. A relevant subsequent conviction ordinarily carries a minimum six-year disqualification.
What is the ban for refusing a specimen?
A first conviction for refusal or failure under the principal station or hospital provisions carries a minimum four-year disqualification, rising to six years for a relevant subsequent conviction.
Refusing to provide a specimen is one of the worst things you can do.
Nobody likes being arrested and as we’ve discussed approximately 40% of drivers are acquitted or are not convicted. But these were drivers who provided a specimen.
If you fail to provide a specimen by simply refusing, you make the State’s case so much easier. It’s an offence all of its own (separate from the drink driving or drunk in charge offence that you were originally arrested for) and all the Gardai have to prove is that you were lawfully arrested and a demand was made of you to provide a specimen and that you failed to comply.
By refusing to comply you have effectively done the prosecution work for them, and exposed yourself to a possible 4 year disqualification.
Can the judge decide not to disqualify me because I need my licence for work?
No. Never. For these offences, personal hardship does not allow a judge to ignore a mandatory minimum ban.
Employment and family circumstances can be relevant to the overall sentencing exercise, but they do not turn a mandatory disqualification into an optional one. If you’re convicted you will be disqualified. The trick is not to be convicted.
The current disqualification rules and tables appear in section 26 of the Road Traffic Act 1961.
16. What happens in court, and can I appeal?
Why does knowing the judge matter?
People sometimes imagine that judges are all alike. They are not.
Every judge must apply the same legislation, respect binding decisions and require the prosecution to prove the charge beyond reasonable doubt.
But judges remain human beings. They bring different experience, instincts and views about what evidence matters.
That’s not unusual. In fact, if you ever listen to judges addressing a jury at the end of a trial they’ll advise them to bring their own ‘life experiences’ and ‘common sense’ to the business of making a decision.
One judge may be deeply concerned by a missing document. Another may regard it as insignificant. One may find a witness careful and convincing.
Another may focus on an inconsistency that the first judge barely noticed. Some judges take a particularly strict view of drink driving.
Others approach the allegation with greater detachment and concentrate closely on whether every legal element has actually been proved.
I have appeared in front of judges in this country who, regardless of the evidence, would convict defendants every time. These judges, often male, were often known derisively by lawyers as “a man of conviction”.
This does not mean that a lawyer should tailor the truth to the judge. That should never happen. Trust between a judge and a lawyer is paramount. A court must be assured that what you are telling them is the truth.
Trust takes a long time to earn, but you can lose it in seconds.
But your allegiance is to your client, not the State, and it is not your job as a defence lawyer to help or assist the State in prosecuting your client.
The evidence does not change. The law does not change. What changes is how the case should be explained, organised and emphasised so that the real issue is understood.
I have appeared before judges throughout Ireland for many years.
That experience matters because legal knowledge alone does not tell you how a particular courtroom works. A solicitor must know the case, but also understand the person who will decide it.
Sometimes these rural courtrooms have a look of the ‘Old West’ to them. You have to know when you enter the room, who is for you and who is against you. And by ‘who’, I mean the presiding judge. You do not want to antagonise a judge.
I have seen lawyers do this over the years in various courts, taking ‘principled stands’ in open court or simply arguing relentlessly with the judge. This never ends well.
The public may not be experienced enough to detect overblown ‘grandstanding’ but the judge is. And if you think they’ll allow a lawyer to use their courtroom as a soapbox think again. In the end, the people who suffer from these antagonistic situations, are not the lawyer -and certainly not the judge- it is the client.
Knowing the judge cannot guarantee an outcome. It can, however, affect preparation, choice of emphasis, the order in which an argument is presented and whether a point is likely to need fuller explanation.
The first court date
The first listed date is not the trial date. A trial date is the date when witnesses are sworn in and evidence is heard. Depending on the court, disclosure, legal issues and witness requirements, the case may be adjourned before hearing.
You must attend. Bring the summons and arrive early.
Guilty plea or contested hearing
A decision to plead guilty should follow advice on the evidence, available defences, credit for an early plea and the consequences of conviction. Do not plead guilty simply because a number appears on a certificate. Do not contest a properly proved case because an AI chatbot promised a loophole.
Remember: all AI chatbots work the same way.
They drag material published online together and categorise it in incredible ways. Unfortunately they hallucinate and can provide answers that are totally incorrect or are from foreign legal systems rather than Irish. Even when you use Claude.ai, every answer comes with an admission in small print: “Claude is AI and can make mistakes. Please double-check responses”.
If you ask ChatGPT whether its answers are always correct it will say:
“No. I can misunderstand your question, rely on outdated information, misread a source or confidently join facts together in a way that sounds convincing but is wrong”.
While I can tell if Claude or ChatGPT gives correct answers, can you?
Appeal to the Circuit Court
A person convicted in the District Court can appeal to the Circuit Court. It is a full rehearing.
The appeal is in front of a new judge i.e. a Circuit Court judge.
The fact that the appeal is heard again by a different judge can be important. The evidence is presented afresh and the Circuit Court judge makes an independent decision. A point that received little weight in the District Court may be assessed differently on appeal.
The usual deadline to serve and lodge the notice is 14 days from the decision. The Courts Service criminal appeals guidance explains that the required recognisance (appeal papers) stays the District Court order. Section 27 of the Road Traffic Act 1961 provides for suspension of a consequential disqualification where notice is lodged within 14 days and the recognisance is duly entered.
Do not wait until day 14 to seek advice.
Can a driving ban be postponed?
The legislation gives a court a limited discretion to postpone the start of a disqualification for up to six months where a special reason relating to the person’s circumstances, including employment, is presented.
This is not the same as cancelling or shortening the ban. People sometimes seek to postpone the ban so that they can “get their affairs in order”.
A judge has a discretion to postpone the ban for a maximum of 6 months. In practice they are often reluctant to go to that limit as they have the view that the earlier you start it the earlier it finishes.
Can I apply for early restoration of my licence?
In some cases, yes.
the disqualification must be for more than two years,
it must be the first relevant disqualification order within ten years,
an application may be made after half the period has been completed,
at least 14 days’ written notice must be given to the Garda superintendent for the district where the applicant ordinarily resides, and
even if granted, the ban must have operated for at least two-thirds of its original period or two years, whichever is greater.
The judge may consider character, conduct since conviction and the nature of the offence. Restoration is discretionary, not automatic.
At the very least you need to have paid whatever fines were imposed when you were disqualified originally, handed in your licence to be endorsed and not to have committed any further offences since. If you haven’t, you can forget about having your licence restored early.
17. Will a drink-driving conviction affect my job, insurance or travel?
Employment
A conviction does not automatically end every job. The real effect depends on the role, employment contract, regulatory obligations, insurance, the need to drive and the employer’s policies.
Professional drivers and people whose work requires a vehicle face obvious practical risk. Regulated professions may also have reporting obligations. Obtain employment advice before making assumptions or disclosures.
I represented a truck driver who received a two-year disqualification. His employer valued him and created a warehouse role so that he could remain in work.
Not every employer can do that, of course. But it is a useful reminder that a ban and a dismissal are not automatically the same thing. A calm, early conversation may reveal options that panic hides.
Insurance
A conviction or disqualification is likely to affect motor insurance. You must answer an insurer’s questions honestly and comply with the policy’s notification terms. Driving uninsured creates a separate and serious problem.
Travel
A District Court drink-driving conviction does not automatically prevent all foreign travel. Entry and visa rules differ by country and can change. Answer official immigration questions truthfully and obtain destination-specific advice, particularly for visa applications.
A conviction for drink driving will not prohibit travel to the United States or other countries unless it is connected to some other serious incident.
Criminal record and spent convictions
A court conviction is a criminal conviction. The Criminal Justice (Spent Convictions and Certain Disclosures) Act 2016 can allow certain District Court convictions to become spent after seven years where all statutory conditions are met.
Road traffic convictions receive particular treatment under the Act, but there are exceptions, excluded sentences and disclosure contexts in which information may still be required.
A conviction may be regarded as ‘spent’ but that doesn’t mean that it disappears in some way.
Just because you are no longer required to declare a conviction (for the purposes of employment) doesn’t mean it has disappeared after 7 years (it has not) or that you don’t have to declare it to a future insurance company when taking out insurance: you definitely do.
18. What should I do now if I have been arrested?
Keep every document and envelope. Photograph them as a backup.
Write a factual chronology. Include times, words, people and locations. Mark uncertainty honestly.
Preserve video and electronic evidence. Dashcam, location history and messages may be lost automatically.
Do not discuss the facts online. A public post can become evidence.
Check your licence status. An arrest, fixed notice, conviction and appeal have different effects.
Obtain advice before deadlines expire. Fixed-charge and appeal deadlines are short.
I am Patrick Horan, a solicitor practising in road traffic law throughout Ireland. Before qualifying as a solicitor in December 2009, I served as a member of An Garda Síochána from 1997 to 2007. That combination means I examine the case both as a lawyer and with practical knowledge of Garda procedure.
I have also appeared before judges everywhere across the country. That does not give me a crystal ball. It gives me something more useful: practical knowledge that judges do not all think alike, and that the same point may need to be presented differently in different courts.
19. Frequently asked questions about drink driving in Ireland
How many drinks can I have and still drive legally?
There is no safe universal number. Alcohol concentration varies by person, drink, timing, food and metabolism. It is not scientifically possible to determine this but the general rule is that it takes 2 hours to process one standard pint of lager. Visit www.drinkaware.ie for more information on how long it takes the body to expel alcohol.
Is the roadside breath test the evidence used in court?
Not for an excess-alcohol reading. It is a preliminary screening test. The evidential result comes from the Garda-station Evidenzer or an MBRS blood or urine certificate.
Can Gardaí breath-test every driver at a checkpoint?
At a properly authorised mandatory testing checkpoint, Gardaí have statutory powers to stop vehicles and require preliminary breath specimens in accordance with section 10.
Can a Garda breath-test me after a minor collision?
Yes, and they will test you. Section 9 provides preliminary testing powers following collisions and in other defined circumstances. The exact subsection and evidence should be checked.
Can Gardaí make me wait for a roadside device?
Yes. Section 9 permits a requirement to remain at the place, or nearby, for up to one hour where an approved device is not immediately available in the applicable circumstances.
What happens if I refuse the roadside test?
Arrest. Refusal or failure without a lawful basis is an offence. A later station refusal may create a separate, more serious disqualification exposure.
Can I choose blood instead of breath at the Garda station?
No. The Garda requirement and statutory medical provisions determine the route. Where blood or urine is required, you can choose to give either blood or urine.
Can I insist on urine instead of blood?
Yes, provided you provide urine. If you opt for urine but cannot provide any (eg some anti-depressant medication makes it hard to urinate) a Garda will then require you to allow the doctor or nurse take a specimen of blood from you. You must then provide blood.
Which of the two breath readings is used?
Section 13 provides for the lower determined concentration to appear on the two statements.
Does refusing to sign the breath statement invalidate it?
No. The Act expressly provides that the evidential provision can still apply where the person fails to sign.
Will I receive part of my blood or urine specimen?
The two sealed specimens must be offered so that you may retain either one. If you decline, both are sent to the MBRS.
What is the three-hour rule?
The excess-alcohol offence concerns a concentration exceeding the statutory limit within three hours after driving, attempting to drive or being in charge. In layman’s terms, the specimen of breath, blood or urine must be taken within 3 hours of the time of driving.
Can I defend the case because I drank after driving?
Highly unlikely, and then only if the demanding requirements in section 18 are met. The court must be satisfied that without the later drinking the concentration would not have exceeded the limit. Expert evidence is required.
What is the “hip flask defence”?
It is the informal name for a properly evidenced claim of post-driving consumption. It is not a loophole and does not apply merely because someone says they drank after driving
Can I be prosecuted if I was asleep in the car?
Possibly. A drunk in-charge prosecution turns on whether you were in charge in a public place with intent to drive. Section 5 presumes intent until the contrary is shown by you.
Can I drive while waiting for my summons?
An arrest alone does not disqualify you. But you must check whether any fixed-charge disqualification, existing ban or court order applies. And you must have insurance.
Why did the Garda give my car keys back?
Returning keys does not amount to a finding that you were sober, safe to drive or free from prosecution. Do not drive again unless you are legally entitled, properly insured and certain that you are safe. The Gardai must return your property to you when you are released. Your keys are part of your property. That’s why they are handed back to you.
Is a drink-driving court case open to the public?
District Court proceedings are generally held in public. Other defendants, lawyers, Gardaí, journalists and members of the public may be present. Most people in the courtroom are occupied with their own cases.
Will I go to prison for a first drink-driving offence?
Highly unlikely. The principal offences permit imprisonment for up to six months, but imprisonment is not the ordinary outcome for a straightforward first excess-alcohol conviction. The reading, driving, collision, previous record, refusal, aggravating facts and plea can affect sentence.
What happens at my first court date?
The first date is often administrative rather than the final trial. Your solicitor may seek disclosure, identify the charge, enter an appearance and arrange the next step.
Does the judge have to ban me if I need my licence for work?
If convicted of an offence carrying a mandatory consequential disqualification, yes, the statutory minimum applies. A limited postponement of commencement may sometimes be sought, but hardship does not erase the ban.
Can I get a three-month ban in court for the same reading as a fixed notice?
No. The three-month and six-month outcomes described above are fixed-charge disposals. If prosecuted and convicted, the court minimum applies ie 6 and 12 months.
When does a court disqualification start?
A consequential disqualification ordinarily starts on the fifteenth day after it is made. A qualifying appeal lodged within 14 days with the required recognisance suspends it pending appeal.
How long do I have to appeal?
The normal District Court to Circuit Court criminal appeal period is 14 days from the decision.
Is the Circuit Court appeal a new hearing?
Yes. It is a rehearing of the case.
Can I have a two-year ban restored early?
No application under section 29 is available unless the disqualification is for more than two years. You can only apply to have your licence restored early if you received at least a 3-year ban or more. You cannot apply to have your licence restored if you got a disqualification of 2 years or less.
Does Flanagan mean every Evidenzer can be dismantled?
No. It confirms that a court may order an appropriate inspection where justified by evidence. Scope remains a matter for judicial decision in the individual case.
Does Ratinskis mean chain of custody never matters?
No. It means an alleged gap does not automatically defeat statutory presumptions. Evidence capable of rebutting the presumption remains important.
Will a conviction stop me travelling to America, Canada or Australia?
No. Each country asks different questions and rules change. Road traffic offences are classified as “Crimes of non-moral turpitude” in the US and will not usually stop travel to that country. These offences do not involve ‘intent’ and can be contrasted with “Crimes of moral turpitude”, where an intent to commit an offence is present e.g. sale and supply of drugs, assault, criminal damage etc.
Will my employer find out?
That depends on your role, contract, vetting, regulatory duties and whether driving is required.
Is there any point contacting a solicitor if the reading is high?
Yes. A solicitor should assess proof, procedure, advice on plea, mitigation, appeal and the practical consequences. A high reading may affect possible outcomes, but it does not remove the prosecution’s obligation to prove the charge lawfully.
In it's latest report the MBRS concluded that the "median alcohol level in blood in 2025 was 157mg/100ml".
The alcohol limit is 50mg, which means that the average motorist arrested was more than 3 times the legal limit.
