Vehicle collisions claimed one life and injured a number of other people in Central Alberta during the weekend.
Rocky Mountain House RCMP continue their investigation of a two-vehicle collision shortly after midnight on Saturday, about 11 kilometres west of the town.
Police report that a 20-year-old man died in hospital of wounds sustained when a pickup truck struck the rear of a car that had stopped on the shoulder.
There were six people in the car and the driver of the pickup was alone in his vehicle at the time of the crash, said Cpl. Shawna Lozinski, a member of the Rocky RCMP detachment.
The man who died had been a passenger in the car, said Lozinski.
Jaws of Life had to be used to remove two of the six people from the car.
Injuries ranged from minor to serious, with victims taken to hospitals in Rocky, Red Deer and Calgary.
Hwy 11 was closed for four hours while emergency crews worked at the scene.
Later the same morning, Stettler RCMP were called to a single-vehicle collision that severely injured an 18-year-old man.
Police say the young man and three passengers were travelling in a full-size pickup that rolled at the intersection of Hwys 11 and 12 near Nevis, 20 kilometres west of Stettler, just before 2:30 a.m.
Heavy fog at the time meant STARS air ambulance was unable to fly to the scene.
The young driver, who was not buckled in, suffered critical injuries after being ejected from the truck.
He was taken by ground ambulance to Red Deer Regional Hospital Centre.
The other three people, two men aged 31 and 26 and a 20-year-old woman, were treated at Stettler hospital for injuries not believed to be life threatening.
Police believe speed and poor visibility due to the heavy fog were factors in the collision. Alcohol is not believed to have been a factor.
