A three-vehicle collision Monday evening on Hwy 11 east of Rocky Mountain House sent one driver to hospital by STARS air ambulance.
At 7 p.m. about 30 km east of Rocky, a westbound truck waiting to make a left turn was struck from behind by a minivan, pushed into eastbound traffic and struck by another truck.
The driver of the minivan was taken by STARS to an Edmonton hospital. Other occupants of the minivan were transported by land ambulance to Rocky Mountain House hospital.
Other people involved in the collision were not injured.
Rocky RCMP are still investigating. Alcohol is not considered a factor.
