RCMP in eastern P.E.I. are crediting a passing motorist with saving the life of a man whose truck rolled off the highway in eastern P.E.I. Thursday.

A 59-year-old man from Sturgeon suffered serious injuries when his truck rolled over and ended up on its roof in a small brook Thursday evening.

At 8:10 p.m. Thursday Kings District RCMP received a 911 call reporting the accident on Route 17 in Lower Montague. A passing motorist noticed tracks leading off the roadway and stopped to check the area.

RCMP Sgt. Kevin Baillie said the motorist who found the truck was not the first to notice something odd on the highway.

"Another motorist came along while we were still at the scene and advised he had passed by the scene over an hour earlier and had noticed the snow on the road at that time but hadn't stopped," said Baillie.

"We believe the driver was likely in the vehicle and trapped for over an hour before he was located. I think it would be fair to say that if the second driver hadn't noticed the snow on the road and stopped and found the vehicle the driver would likely have perished because there is no way he could have got himself out of the vehicle and the vehicle wasn't visible from the roadway."

The Montague Fire Department used the Jaws of Life to open up the vehicle and remove the driver, who was the only occupant.  Temperatures at the time were around -20C, and the driver's body temperature had dropped very low. RCMP are crediting the passerby with saving the driver's life.

The driver was the only occupant of the vehicle. His name has not been released.
