A woman suffered serious, potentially life-threatening injuries after a single vehicle rollover early today on westbound Glenmore trail just past Crowchild.
Police say the vehicle went off the road and into a tree at about 1:20am.
Police say they don’t know what caused the woman in her 20’s to lose control of her vehicle.
Two other vehicles heading eastbound were involved in a nearly simultaneous crash as one driver slowed down to offer help and her vehicle was struck by another coming from behind.
There were no serious injuries in that collision.
Police say it’s too soon to say if speed or alcohol were factors in the initial rollover.
Westbound Glenmore was closed for about 5 hours while police investigated, but was opened back up again by 6:15am.
