Alcohol is believed to be a factor in a rollover Saturday afternoon near the Belle Plaine overpass on Highway 1.
RCMP were called to the Trans-Canada Highway around 4:48 p.m. after a white 2009 Dodge Ram heading eastbound went into the ditch, lost control and rolled.
Police say the truck came to rest by a body of water. A search was done of the water to make sure no one else had been in the truck.
A 33-year-old man was airlifted to hospital in Regina.
Police say the investigation is continuing.
