⚖️ Drink Driving — Road Traffic Act

Caught Drink Driving
in Ireland.

A drink driving charge in Ireland means automatic disqualification — even for a first offence. It also means a court appearance, a potential criminal record, and consequences that affect your insurance for years. What happens next depends heavily on your reading and how well you are represented.

What happened to Ronan

"I had two pints at the match and drove home. I was stopped at a checkpoint two miles from my house. I was sure I was fine."
— Ronan, Swords, Dublin

Ronan passed the roadside breathalyser but was brought to the Garda station for an evidential breath test. His reading came back at 46mg per 100ml of breath — just above the legal limit of 22mg. He was charged, given a court date, and told he faced losing his licence. He drove for work and a disqualification would have cost him his job.

What the law says about drink driving in Ireland

Under the Road Traffic Act, it is an offence to drive or attempt to drive while over the legal alcohol limit. The legal limit in Ireland is 50mg of alcohol per 100ml of blood, 67mg per 100ml of urine, or 22mcg per 100ml of breath. For learner drivers and professional drivers, the limit is lower at 20mg per 100ml of blood.

Conviction results in mandatory disqualification: a minimum of 1 year for a first offence at lower levels, up to 2–4 years for higher readings or repeat offences. Fines of up to €5,000 apply. Imprisonment is possible for high readings or repeat offences. All convictions are criminal matters recorded on your Garda record.
