WAS DRIVING ABOUT 30 MPH WHEN THE CAR BEGAN ACCELERATING WITHOUT ME APPLYING PRESSURE TO THE GAS. I WAS COMING TO A LIGHT TO MAKE A RED TURN AND WHEN I APPLIED THE BRAKES THEY WOULD NOT SLOW DOWN MY VEHICLE SO MY SPEED INCREASED. THE STEERING WHEEL THEN LOCKED AND BEFORE I KNEW IT A CAR HAD COLLIDED WITH ME CROSSING IN FRONT OF ME. MY CAR WAS TOTALLED.
