Canadian police are investigating a suspected road rage incident that left a man clinging to the front end of a semi truck traveling down the Coquihalla Highway last week.

The incident began around 1 p.m. on December 15 at the Inks Lake brake check on Highway 5, according to local outlet Castanet.

Authorities say that a road rager and a semi truck driver got into some kind of confrontation while at the brake check. As the semi truck driver exited the area, the other person reportedly jumped onto the front bumper, clinging to the bull bar, as the truck travelled down the highway.

Dash cam video captured by John Hiscock shows the man waving as he drove past.

“I pulled over to go past him and all of a sudden you see a face and an arm come up from the front of the truck,” Hiscock told Castanet. “And shortly after I passed them I looked back in the mirror again and there was an unmarked police car going up after them, followed by an ambulance.”

Police reportedly intervened and the incident ended without serious injury.

The incident remains under investigation by RCMP.
