ON THE MORNING OF JUNE 9, 2009 I WAS TRAVELING SOUTH ON I-93 NEAR THE TOWN OF MEDFORD, MA. I WAS ON MY WAY TO LOGAN AIRPORT TO RETURN THE 2009 TOYOTA PRIUS I HAD RENTED THAT PREVIOUS WEDNESDAY. IT WAS APPROXIMATELY 9:30 AM; THE FREEWAY WAS STILL BUMPER-TO-BUMPER WITH RUSH HOUR TRAFFIC. I WAS IN THE LEFT-HAND LANE OF THE HIGHWAY AND TRAFFIC WAS STOP AND GO. A GAP OPENED UP IN TRAFFIC AND I ACCELERATED. THE CAR IN FRONT OF ME (APPROXIMATELY 60') SUDDENLY STOPPED. I SLAMMED ON THE BRAKES BUT MY CAR KEPT GOING. THERE WAS NOTHING I COULD DO AS MY CAR PLOWED INTO THE CAR IN FRONT OF ME, AT THE SPEED OF APPROXIMATELY 10 MPH. THE IMPACT WAS SUFFICIENT TO DISLODGE MY FRONT LICENSE PLATE. THERE WAS NO APPARENT DAMAGE TO THE CAR IN FRONT OF ME, HOWEVER THE TWO PASSENGERS WERE EXTREMELY SHAKEN UP. THERE WAS A MASSACHUSETTS STATE TROOPER ON THE SCENE WHO TOOK ALL THE INFORMATION BUT DID NOT FILE A REPORT. AS SOON AS I COULD, AT ABOUT 11:00 AM, I CALLED MY INSURANCE COMPANY, USAA TO REPORT THE ACCIDENT, AND I EXPLAINED ALL OF THE DETAILS TO THEM. *TR
