Officials say the man had exited his SUV after an earlier collision when he was struck, describing the incident as “absolutely tragic.”

Schmidt warns drivers never to leave their vehicles on major highways, even in the event of a crash.

The man, along with two others, were rushed to hospital, though the condition of the other two remain unknown at this time.

“Unfortunately, he was pronounced deceased in hospital a short time later. An absolute tragic outcome here this morning,” Schmidt said.

OPP urging drivers to stay in vehicles after crashes

Investigators from the OPP’s Collision Reconstruction Team remain on scene, speaking to witnesses and working to determine what happened in the moments leading up to the crash.

Schmidt stressed that exiting a vehicle on a live highway is dangerous, even after a crash.

“Standing outside a highway on a live lane, after a collision… unfortunately, just an absolutely tragic situation,” he said.

“If you have a breakdown, if you have an issue with your vehicle, we don’t want to see people being pedestrians out on the highway.”

Anyone with additional information or video footage is asked to come forward and contact investigators.
