A young couple on a weekend away were among five people who lost their lives in four road crashes across the country over a 48-hour period. There was a total of seven road-related deaths since Friday.
Teenage "sweethearts" Gary Kelly (19) and Delia Keary (18) died within a day of each other following a collision with a truck on Friday night.
The couple were on their way to Kerry for a weekend away.
Mr Kelly was pronounced dead at the scene of the accident near Abbeyfeale in Limerick.
Ms Keary died on Saturday night at Limerick University Hospital.
Mr Kelly had been training as an apprentice electrician in his home town of Ennis, Co Clare.
His boss, Jerry O'Keeffe, told the Irish Independent that he was an exemplary employee.
"He was a very dedicated worker; he was always there on time, every morning," Mr O'Keeffe said.
"It's such a sad, sudden loss of human life. They were going out for maybe five years, young school sweethearts, I suppose."
A female garda at the scene remained for five hours past the end of her shift to ensure the couple could be removed from the vehicle.
