Four motorcylists were among the seven people who died in road crashes over the weekend, with four of the deaths in Northern Ireland.
A man who died when his motorbike was in collision with a car on the Fethard Road outside Clonmel, Co Tipperary has not yet been named.
In Dublin, two people were killed in a crash on Saturday morning involving a car and a rigid lorry on the N2 Finglas to Ashbourne Road at Ward's Cross.
Daire Maxwell (16), Dunshaughlin, Co Meath, was a passenger in the lorry and died at the scene. Donna Beresford (39), Kippure Park, Finglas, Dublin, who was the driver of the car, was pronounced dead at James Connolly Memorial Hospital. The driver of the truck was also taken to James Connolly hospital.
These fatalities have brought the total number of road deaths in the Republic this year to 130.
However, this figure is still below the number of road deaths for the same period last year.
Road Safety Authority chief executive Noel Brett said the recent cluster of deaths was tragic, but there was still a reduction on last year's figures.
"Last year, we had the second-lowest level of road deaths in 41 years and this year's figures are 24 fewer than at the same time last year," he said.
In the North, a teenager who died was named as Callum McComskey who would have celebrated his 18th birthday next month. He crashed off the Ballyvalley Road near Mayobridge, Co Down in the early hours of Saturday morning and hit a tree.
A motorcyclist from Glasgow, 45-year-old Iain McDonald died when his bike was in collision with a car on the Seacoast Road at Limavady, Co Derry.
He was visiting Derry for the North West 200 motorcycle road races.
Two more motorcyclists died close to the race circuit when their bike crashed with two cars on the Portstewart Road, Coleraine, Co Derry.
They were named as Trevor Connor (39) and Sadie McClarty (36), both from Ballymoney, Co Antrim.
