One man is dead after a three-vehicle collision between a pickup truck, SUV and semi-truck in Broket, Alta. on Friday afternoon.

At about 1:50 p.m. on Friday, Piikani Nation RCMP, Fort MacLeod RCMP, Pincher Creek RCMP and fire services responded to the collision at the intersection of Highway 3 and Highway 280.

The semi-truck was traveling eastbound on Highway 3 when it rear-ended the pickup truck and SUV at the intersection, according to a Saturday news release from RCMP.

The 62-year-old male driver of the pickup truck was declared deceased at the scene. The 62-year-old female passenger was airlifted to Calgary's Foothills Medical Centre with serious, life-threatening injuries, police say.

The 34-year-old female of the SUV and her passenger, a 2-year-old female child, were taken to a hospital in Lethbridge via ambulance. Their injuries are currently unknown.

The driver of the semi-truck, who was the only occupant in that vehicle, was taken to the hospital in Fort MacLeod with non-life-threatening injuries, the release said.

Highway 3 was closed for several hours on Friday and traffic was re-routed as RCMP and the Alberta Commercial Vehicle Enforcement Branch investigated. It re-opened later Friday night.

RCMP are continuing their investigation into the collision. They say drug or alcohol impairment were not a factor in the crash.
