Minister for Transport, Leo Varadkar and An Garda Síochána have given their support to the drinkaware.ie/RSA Morning After Campaign.
As the Christmas party season gets into full swing this weekend, drinkaware.ie is encouraging people to pace their drinking and to remember the morning after.
Drinkaware.ie chief executive, Fionnuala Sheehan, said: "The reality is it takes your body about one hour to get rid of one standard drink - that's a glass of beer or cider, a small glass of wine, or a pub measure of spirits. So if you are drinking on a night out this Christmas, you might still be over the legal limit the next morning."
The message from drinkaware.ie is to take responsibility for your drinking.
"Do the maths and if you suspect that you might not be okay to drive, then make alternative arrangements," added Ms Sheehan.
"Public transport will operate over much of the festive season and if this isn't an option for you, plan ahead and designate a driver or book a taxi."
Assistant Commissioner Gerard Philips said: "We do not wish to hamper anyone's enjoyment over the festive period but we must remind every driver that wherever they socialise and consume alcohol, whether it be in a bar or a house, the same enforcement and now lower, drink driving limits apply.
"We appeal to every driver to ensure they are completely alcohol free before they think about driving any vehicle, no matter what time of the day or night it may be. Never risk guessing your alcohol content, it could prove very costly if you are wrong. If you're in doubt, don't drive and find an alternative means of travelling."
www.drinkaware.ie have partnered with Hailo Taxi to distribute over €500,000 worth of free taxi vouchers to people this Christmas. The vouchers for €5 off your taxi home are available in pubs, bars and restaurants across Dublin throughout December.
