'Fear Factor' Contestant Injured in Stunt Accident

A "Fear Factor" contestant got a little more than she bargained for when the stunt truck she was riding on top of hit another car ... but she escaped with no major injuries.

We're told the driver of the stunt truck -- which was going less than 20 mph at the time -- had his vision blocked for a brief period of time, resulting in the truck hitting a parked car that was part of the stunt.

According to our sources, the woman was in a safety harness on the truck and she was shook up from the collision, but was not thrown from the vehicle. She was transported to the hospital by an on-set EMT. We're told she suffered no major injuries and was released from the hospital after a few hours.
