Gardaí have reminded motorists that a Bank holiday enforcement campaign is in operation on the roads and will remain on stream over the weekend.
Checkpoints as well as mobile patrols will be visible on roads across the country, after nine people were killed and more than 140 injured over the August weekend last year.
A Garda statement said there would be a particular emphasis on checking for speeding, drink driving and the non-wearing of seatbelts.
