A man in his 40s has been killed in a collision between a van and a truck on the N24 near Carrick-on-Suir.
The two vehicles crashed on the road between the Dove Hill retail area and Carrick at about 7.25 this morning.
The driver of the van, understood to be heading in the Waterford direction, was fatally injured in the collision.
The truck-driver is believed to have suffered minor physical injuries.
Emergency services were quickly at the scene and gardaí closed off the road to allow a forensic examination of the scene to take place.
That section of the N24, part of the main route between Waterford and Limerick, is expected to be closed for much of the day.
Gardaí have appealed for any witnesses or anyone with information, including dash-cam footage from the area at that time, to contact them.
