Stopped on a 2 lane highway to wait for on-coming traffic and got hit from the rear by a 95 F250...I had the windows down and heard him lock up his tires, I hit the gas to minize the impact...curled the rear bumper, took out the rear lights, bent the trailer hitch and broke my seat back...Walked away with a sore body and a little headache from the impact...The other driver was a 18 year old kid, distracted...looked up and saw me sitting there too late to do anything but hit the brakes.
