Gardai are out in force this weekend as they launch a major crackdown on drink and drug driving.
Last night, over 300 drivers were tested at checkpoints across the city with four people arrested.
But what are the drink driving limits in Ireland?
The limit is getting lower and lower and currently stands at blood alcohol level of 50mg for experienced drivers.
The limit is lower for learner drivers and professional drivers, at a blood alcohol level of 20mg.
This means if you have one drink you could well be over the limit.
Here are a few examples of how long you should stay away from the car after a night out, keeping in mind the morning after is considered the most dangerous time for drink driving.
10 pints of lager/stout
According to Drink Aware you can not get into the car for 20 hours after you finish your final drink.
So of you retreat to bed at midnight, you can not get back into a car until 8pm the following night.
1 bottle of wine
If you polish off one bottle of red or white wine you will have to stay off the road for eight hours after you finish.
10 vodka and cokes
If you are sticking to vodka and manage to down 10 altogether, that would mean no driving for 10 hours after your final drink.

12 pints and 6 vodkas with mixers
Going for a proper wild night, drink in the pub for the day and then go to a nightclub and switch to the vodka.
This one will have you feeling particularly bad the next day and that is reflected in how long you have to stay off the road.
You will have to avoid driving for 30 hours after your last drink, so basically just stay away from the car for the weekend.
