People are being urged to plan their movements over the long weekend.
A campaign from Drinkaware, is warning about the dangers of driving the next day.
77% of adults agree driving the morning after drinking is just as dangerous as drink driving, however only 65 per cent of those under 35 actually recognise the risk.
Dearbhla O'Brien, CEO with Drinkaware says food and coffee will not make any difference if driving the morning after.
