More than 300 drivers have been arrested on suspicion of drink and drug driving since the end of November. Gardai launched a Christmas Road Safety Campaign, which started on Friday November 29th, which hops to minimise traffic chaos in the lead up to Christmas.

In total 264 drivers were found to be driving under the influence of alcohol while 37 motorists were under the influence of drugS, according to Newstalk.

Over 150 new gardai have been assigned to an operation open city for Cork, Dublin and Limerick to help traffic through more Garda patrols on major routes.

Gardai have said,

"Do not put yourselves or other road users at risk. Operate within the applicable speed limits and never drive under the influence of alcohol or drugs", Gardaí add.

So far this year 136 people have lost their lives on Irish roads.

Here is a couple of 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.

Eight glasses of prosecco

If you indulge in a few glasses of prosecco, eight to be exact, then you will not be allowed to drive again for 12 hours.

Eight glasses of the sparkling wine is equivalent to 12 standard drinks.

One 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 or other mixers

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.

10 pints of beer, stout or lager

Lets just say you do the 12 pubs, skipping one or two because you can't handle it, and end up having 10 pints of Guinness, Heineken, Carlsberg or some other lager or stout in and around 4.5%.

According to Drink Aware, you can not get into the car for 20 hours after you finish your final drink.

So if you retreat to bed at midnight, you can not get back into a car until 8pm the following night.
