JULY 3, AT APPROXIMATELY 10:30 PM WE CAME HOME AND PARKED THE CAR IN THE DRIVEWAY WHICH IS AT A SLIGHT INCLINE. I GOT OUT OF THE VEHICLE TO UNLOAD ITEMS FROM THE BACK, AND AS I CAME AROUND ON THE PASSENGER SIDE THE CAR MADE A LOUD POP SOUND AND THE CAR BEGAN TO ROLL BACKWARDS AND WAS MAKING AN AUDIBLE CLICKING NOISE. IN AN INSTANT I WAS WORRIED THAT THE VEHICLE WAS GOING TO RUN OVER ONE OF MY KIDS WHO WERE OUTSIDE AS I UNLOADED THE VEHICLE SO I MANAGED TO CLIMB IN AND AS I REACHED OVER TO TURN OFF THE IGNITION, THE CAR BUMPED OVER WHERE THE DRIVEWAY AND STREET MEET KNOCKING ME OFF BALANCE. AS I FELL FROM THE CAR, MY RIGHT LEG GOT JAMMED IN THE PASSENGER DOOR, MY HEAD WHACKED THE BOTTOM FRAME OF THE DOOR, AND RIGHT BEFORE THE CAR ROLLED TO A STOP, THE FRONT PASSENGER TIRE STARTED TO RUN OVER MY LEFT LEG AS I TRIED TO KEEP THE LEG OUT OF THE PATH OF THE WHEEL. I SUSTAINED MULTIPLE INJURIES INCLUDING A HEAD INJURY, CONCUSSION, SPRAINED KNEE, CUTS AND BRUISES. *TR
