I WAS DRIVING IN THE RAIN, GOING ABOUT 55-60 MPH, WHEN ALL OF A SUDDEN THE CAR IN FRONT OF ME SLAMMED ON ITS BRAKES AND ATTEMPTED TO MAKE A LEFT TURN (LIKE THEY ALMOST MISSED THE STREET AND TRIED TO COMPENSATE LAST MINUTE) I SLAMMED ON THE BREAKS BUT COULD NOT STOP IN TIME AND HIT THE CAR IN FRONT OF ME. THE SEATBELT DIDN'T CATCH, NOR DID THE AIRBAG DEPLOY, AND MY HEAD HIT THE STEERING WHEEL, CHIN FIRST.
