VEHICLE SUDDENLY ACCELERATED AND GAS PEDAL STUCK AT ABOUT 65 MILES PER HOUR. I IMMEDIATELY TOOK MY FOOT OFF THE ACCELERATOR AND BEGIN TRYING TO BRAKE THE VEHICLE. AT THE FIRST AVAILABLE OPPORTUNITY, I PULLED TO THE SIDE OF THE EXPRESSWAY. WHILE KEEPING BOTH FEET ON THE BRAKE, I PLACED THE TRANSMISSION INTO PARK.
