GARDAI will be out in force tonight and tomorrow morning to enforce drink driving and road safety legislation.
Checkpoints will be set up in locations across the city and county tonight into the early hours of tomorrow morning, as well as into the later hours of the morning.
Garda are focussed on nabbing drink drivers who opt to flout the law tonight. But the campaign is also targeted at drivers who have been drinking tonight and think they are safe to drive tomorrow.
In one recent incident, a driver was nabbed for drinking while still under the influence of alcohol drank the night before. The passenger then decided to drive but was also arrested on suspicion of drink driving.
The Road Safety Authority has conducted analysis of garda files on fatal collisions throughout the country. The analysis found that in11% of fatal collisions between 7am and 11am, there was alcohol in the driver's system.
As a result, driving the morning after a night out is the main focus of the garda drink driving campaign in the run up to Christmas and into the early days of the New Year.
The campaign is also focussed on speeding, seat belt legislation, and mobile phone use.
Nationally, there were 476 vehicles detected for breaking the speed limit, out of 101,900 vehicles which were monitored.
Among them was one driver detected travelling at 122km per hour in a 50km zone in Dublin, and a driver nabbed for travelling at 109km per hour in a 60km zone near Dungarvan.
