I EXPERIENCED AN UNINTENDED POWERED ROLLAWAY. SPECIFICALLY, AS I WAS REVERSING OUT OF MY GARAGE, I NOTICED SOMETHING ON THE GROUND SO I PUT THE VEHICLE IN PARK TO PICK IT UP. WHEN I EXITED THE VEHICLE, I WAS STANDING IN THE WEDGE BETWEEN THE DRIVER'S SEAT AND THE OPEN DRIVER'S DOOR, AND THE CAR UNEXPECTEDLY ROLLED IN REVERSE. I DID NOT HEAR OR SEE ANY WARNINGS AT ANY TIME THAT ALERTED ME THAT I WAS IN ANY DANGER. I QUICKLY TRIED TO GET BACK INTO THE CAR TO STOP IT (MY 4-YR-OLD SON WAS INSIDE) AND, WHEN TRYING TO GET BACK IN, I WAS PUSHED OUT, FELL TO THE GROUND, AND FOUND MYSELF FIGHTING WITH THE DOOR AND THE TIRE COMING TOWARD MY HEAD AND BODY. I STUCK MY RIGHT HAND INTO THE CAR TO PRESS THE BRAKE PEDAL WITH MY HAND. ULTIMATELY, MY RIGHT HAND FELL OUT OF THE CAR, AND THE CAR ROLLED OVER AND CRUSHED IT. THE DRIVER'S DOOR HIT MY HEAD, WHICH CAUSED A CONCUSSION AND BLEEDING. THE CAR DRAGGED ME FROM THE GARAGE INTO THE DRIVEWAY, CAUSING TIRE BURNS AND SCRAPES ON MY BODY. ULTIMATELY, THE CAR STOPPED WHEN IT ROLLED DOWN THE DRIVEWAY AND HIT A POST ACROSS THE STREET. I WAS THEN TRANSPORTED TO THE HOSPITAL IN AN AMBULANCE, WHERE THEY RAN MULTIPLE TESTS ON MY ENTIRE BODY AND DIAGNOSED MY CONCUSSION AND BROKEN HAND. I HAVE SINCE HAD TO UNDERGO RECONSTRUCTIVE SURGERY ON MY RIGHT, DOMINANT HAND AS THE BONES IN MY HAND WERE CRUSHED BY THE VEHICLE'S TIRE.
