Drink driving limit in Northern Ireland

Drink driving kills. Drinking alcohol slows down your reactions and impairs judgement, making you more likely to have an accident.

The police advise that you should not drive if you have consumed any alcohol at all.

Police advice on how to report a drink driver

How to avoid drink driving

1. Take turns at being the designated driver so you know there’s always someone who’ll be alcohol-free to get you home safely.
2. Take a taxi and leave the car at home. Have a reliable taxi service number handy or a ride hailing app on your phone. And make sure your phone has enough charge to last the evening.
3. Give no-alcohol beers and wine a try. More pubs now carry a host of great tasting alcohol-free alternatives to alcoholic drinks, even spirits!
4. Try an alcohol-free night. Get together with your friends to try something new that doesn’t revolve around alcohol.
