I HAD BEEN DRIVING NORTH ON THE MAINE TURNPIKE WITH MY CRUISE CONTROL ON. IT WAS A CLEAR NIGHT AND THE ROADS WERE DRY. AS I APPROACHED THE TOLL BOTH I TRIED TO TURN MY CRUISE CONTROL OFF, THE CAR DID NOT RESPOND. I THEN TURNED THE CRUISE CONTROL SYSTEM OFF AND THE CAR WAS STILL NOT RESPONDING. I HIT THE BRAKES AND WAS STILL UNABLE TO SLOW THE CAR DOWN. I THEN PUT THE CAR IN NEUTRAL AND SLAMMED ON THE BRAKES AND WAS STILL UNABLE TO GET THE CAR TO RESPOND. AT THAT POINT I WAS TOO CLOSE TO THE TOLL BOTH TO TRY TO SWITCH LANES AND WAS UNABLE TO STOP THE CAR AND HIT THE CAR IN THE TOLL PLAZA IN FRONT OF ME. AFTER THE IMPACT, THE CAR EVENTUALLY COASTED TO A STOP. UNTIL THIS HAPPENED, I HAD NO PROBLEM WITH ANYTHING ON THE CAR. THE CAR HAS NOT BEEN USED SINCE THE ACCIDENT, IN FACT HAS NOT BEEN REPAIRED UNTIL NOW. THERE WERE SOME INJURIES IN THIS CASE. I HAVE A SHOULDER INJURY, WHICH I AM STILL TRING TO GET RESOLVED. I WANT THE INCIDENT TO BE REPORTED DUE TO THE SERIOUSNESS OF BEING UNABLE TO DISENGAGE THE CRUISE CONTROL SYSTEM. AN ACCIDENT REPORT WAS FILED WITH THE MAINE STATE POLICE BUREAU OF MOTOR VEHICLES ACCIDENT SECTION. DT
