What are the legal BAC limits for drink driving in Ireland?
Under the Road Traffic Acts, the general blood alcohol concentration (BAC) limit for fully licensed drivers is 50mg per 100ml of blood (or 67mg per 100ml of urine, or 22mcg per 100ml of breath). For learner drivers, novice drivers (within 2 years of first full licence), and professional drivers including bus and truck drivers, the limit is 20mg per 100ml of blood. These limits are among the lower limits in Europe.
What is the difference between a Fixed Charge Notice and a court summons for drink driving in Ireland?
A Fixed Charge Notice (FCN) is issued for certain road traffic offences. Drink driving above the limit is not typically dealt with by FCN โ it is prosecuted by summons to the District Court. You will receive a court summons requiring you to appear at the District Court on a specified date. You must attend or risk a conviction in your absence.
What are my rights when stopped by the Gardai for drink driving in Ireland?
A Garda must have a reasonable suspicion of alcohol consumption before requiring a preliminary breath test. You are required by law to comply with a lawful breath test request. You have the right to be brought to a Garda station for an evidential breath test (using the Intoximeter machine). You have the right to request a blood or urine test as an alternative. You are entitled to be told of these rights by the Garda.
Can I challenge the breath test result or the Garda procedure in court?
Yes. Defence arguments in drink driving cases often focus on procedural errors โ for example, whether the preliminary test was validly administered, whether the required waiting period before the evidential test was observed, whether the machine was properly calibrated, or whether your rights were properly explained. Procedural defects can result in acquittal even where the reading was over the limit.

What are the mandatory disqualification periods for drink driving in Ireland?
A first offence where the reading is between 50mg and 80mg per 100ml (the lower prescribed limit range) carries a mandatory 3-month disqualification. Readings above 80mg, or a second offence within 3 years of a first, carry a mandatory 1-year disqualification on first offence and 2 years for a second offence. A third or subsequent offence carries a 3-year disqualification. These are mandatory โ the court has no discretion to reduce them.
How does the District Court process work for a drink driving charge in Ireland?
You will receive a summons stating the court date, location, and the charge. On your first appearance you can plead guilty or not guilty. If you plead guilty the judge will sentence you, which will include the mandatory disqualification. If you plead not guilty a hearing date is set and the Garda witnesses are required to attend. Most straightforward drink driving cases are resolved on first or second appearance.
Should I engage a solicitor for a drink driving charge in Ireland?
If the reading was significantly over the limit and you intend to plead guilty, you can appear yourself and a solicitor is not essential. If you intend to contest the charge on procedural or technical grounds, or if this is a second or subsequent offence where the consequences are more serious, engaging a solicitor is strongly advisable. Legal aid is available from the Legal Aid Board if you satisfy the financial means test.

Do penalty points apply to drink driving convictions in Ireland?
Yes. A drink driving conviction attracts penalty points on your licence in addition to the mandatory disqualification. The number of penalty points depends on the specific offence. Penalty points remain on your licence for 3 years. Accumulating 12 or more penalty points within 3 years results in an automatic further disqualification of 6 months.
Is legal aid available for drink driving cases in Ireland?
Criminal legal aid is available for District Court cases where the offence is serious enough to warrant legal representation and the defendant lacks the means to pay. A drink driving charge involving a second offence or a significant period of disqualification may qualify. You apply to the judge at your first court appearance by completing a legal aid application form.
