Six people - three men and three women - were killed on the roads during the bank holiday weekend, despite an increased Garda presence as part of the "Arrive Alive" road safety campaign.
This is the same number that died in road accidents during last year's bank holiday weekend.
However, one of Friday's deaths in Cork will not be counted as a road fatality as the driver died from a heart attack.
In Dublin, one man died and another two passengers were seriously injured following a road collision at Ballyroan Road, Rathfarnham at 1.40 a.m. yesterday.
The driver of the car was in his mid-30s. He received fatal injuries when the car he was driving hit a pole. Two other male passengers were seriously injured and were taken to Tallaght Hospital. A third passenger escaped without injury.
Gardaí still have not named the 21-year-old woman who was killed when the car in which she was travelling hit a tree near Duleek, Co Meath on Sunday afternoon.
Other fatalities included a man who was killed near Ballinalack, Co Westmeath when his car and a truck collided. A 53-year-old woman was killed in a three-car collision near Bandon, Co Cork on Friday, while a 73-year-old woman died in a collision in Piltown, Co Kilkenny on the same day.
The last road safety campaign before Christmas ended last night. The "Arrive Alive" campaign, mounted by the National Safety Council, the Irish Insurance Federation and An Garda Síochána, involved thousands of checkpoints as well as media advertising.
The National Safety Council said it was difficult to gauge the success of such campaigns.
