Six people suffered varying degrees of injuries from a single-vehicle collision east of Bashaw on Sunday afternoon.
Bashaw RCMP say the group was travelling in a pickup truck on Hwy 53 about five km east of town at about 3:45 p.m.
RCMP allege that an inexperienced driver, 16 years old, attempted to pass a slower vehicle and lost control, causing the truck to hit the ditch and roll over.
Four of the people who had been in the truck were taken by ground ambulance to hospital in Camrose, where they were treated for minor injuries and then released.
Two others were flown by STARS air ambulance to hospitals in Edmonton and Calgary with serious injuries that are not considered life threatening. One of the two has been released from hospital.
The collision remains under investigation. A traffic ticket may be issued to the driver, who is alleged to have been driving too fast for road conditions. Bashaw RCMP do not anticipate laying criminal charges.
