RCMP said a semi-trailer truck hauling hempseed collided with a half-ton truck, then flipped onto its side.
Eastbound traffic was blocked, so RCMP rerouted vehicles onto a westbound lane of the highway.
Peter Peters, who was driving the semi, was shaken but wasn’t injured.
“I was so scared … like everybody was going to get killed here,” he said. “That was what I had on my mind. I didn’t want nobody to get killed.”
The accident wasn’t his fault, Peters said.
Two people in the pickup were taken to hospital with unspecified injuries.
