Ontario Provincial Police say a window was smashed during a road rage incident on Highway 401 early Thursday morning.

An OPP spokesperson says officers were called with reports of a collision and since the man was fatally hit by the truck as they were responding, Ontario's police watchdog was notified about the incident.

A driver is facing criminal charges after a car rolled over and burst into flames following a road rage incident involving a group of motorcyclists in Mississauga, Ont., late Thursday evening.
