MY CHILDREN AND I WERE IN A COLLISION THAT WAS SO BAD THE CAR WAS TOTALED. SOMETIME IN THE MIDDLE OF THE COLLISION THE DRIVER SEAT BELT AND THE PASSAGER'S SEAT BELT BEHIND THE DRIVER CAME UNCLIPPED. WE WERE WEARING THEM AND THE PROOF IS ON OUR CHESTS FROM THE BURN. HOWEVER, IF A HEAVY VEHICLE HAD HIT US FROM BEHIND MY SON AND I WOULD HAVE BEEN THROWN FROM THE CAR BECAUSE OF THIS. MY DAUGHTER'S SEAT BELT (BACK PASSAGER BEHIND FRONT PASSENGER SEAT) DID NOT UNCLIP. JUST THE TWO ON THE DRIVER'S SIDE.
