Grey County OPP say a man was injured on Highway 10 after falling out of a moving vehicle.
Police were called just after 7 Saturday evening with a report of an unconscious man on on the road just south of Flesherton.
Police say a 1998 Chevy pickup with the driver and four passengers - all between the ages of 16 and 24, was initially heading southbound.
As the truck slowed and turned left into a commercial parking lot, a passenger in the box of the pickup fell out onto the road and suffered a head injury.
A 24-year old Flamborough Township man was transported to hospital where he is in stable condition.
Police say there are no charges anticipated.
