CAR WAS PARKED DIRECTLY IN FRONT OF RESIDENTIAL GARAGE. I STARTED THE CAR TO PULL IT INTO THE GARAGE. AS SOON AS I PUT THE CAR IN DRIVE, WITH MY FOOT STILL ON THE BRAKE, IT SHOT FORWARD AT FULL SPEED AND CRASHED INTO A TRAILER AT THE BACK OF THE GARAGE. THE IMPACT FROM THE TRAILER BROKE A HOLE IN THE GARAGE WALL. TOTAL DISTANCE TRAVELED WAS ABOUT 25'.
