The deceased, 29, was a passenger in a pickup truck driven by a 25-year-old man when it struck a bridge guardrail on Highway 1 shortly after 6 p.m. Friday, RCMP said in a news release issued late Saturday. Both men got out of the damaged cube truck and stood outside the vehicle, waiting for help, when an eastbound semi-trailer in the process of slowing to pass the cube truck cut it off with its trailer, the release said. The force from clipping the trailer pushed the cube truck into the two men, police said. The men were taken to hospital, where the 29-year-old passenger succumbed to his injuries. The 25-year-old driver suffered serious but non-life-threatening injuries, RCMP said. A 23-year-old man from Brampton, Ont., was driving the semi. Police said he was not injured and immediately pulled over and provided medical aid until paramedics arrived. RCMP say they believe snowy and icy road conditions were a factor in the crash.
