I WAS SITTING AT A JACKS DRIVE THROUGH WHEN MY CAR ACCELERATED ON ITS ON. MY CAR WAS STOPPED WITH MY FOOT ON THE BRAKE. I COULD NOT STOP THE VEHICLE. IT PLOWED INTO THE REAR OF THE VEHICLE IN FRONT OF ME. THERE WAS NO DAMAGE TO THE VEHICLE IN FRONT OF ME BUT THE REESE HITCH ON HIS TRUCK WENT THROUGH MY BUMPER. THERE WAS NO INJURY.
