THE VEHICLE WAS IN A CAR ACCIDENT. MY DAUGHTER WAS SITTING BEHIND ME. WHICH I WAS THE DRIVER AND SHE WAS BEHIND ME ON THE LEFT REAR. MY DAUGHTER HAD THE SEAT BELT ON AND SO DID I. MY CONCERN IS WHY DID MY DAUGHTER ENDED UP GOING ALL THE WAY FORWARD HITTING ME FROM BEHIND WITH HER KNEES THAT THE NEXT DAY MY BEHIND WAS HURTING G. WILL MY DAUGHTER ON THE MEAN TIME DURING THE ACCIDENT HER HEAD HURTLED, NOSE, AND UPPER AND LOWER BACK. IT SEEMS THE SEAT BELT DID NOT LOCK AS SOON AS THE IMPACT BECAUSE IF IT HAD. MY DAUGHTER WOULD NOT HAD GOTTEN A BUMP ON HER NOSE THAT HURTLED WHICH IT MEANS SHE ENDED HITTING MY SEAT WHERE YOU REST YOUR HEAD. TWO HER KNEES HURTED WHEN SHE WENT FORWARD TO MY SEAT AND HIT ME. THREE, IT MADE HER HEAD TOO MUCH FORWARD AND BACKWARD THAT SHE GOT A HUGE BUMP ON THE HEAD AND THE ENTIRE BACK HURTED. FOR ME MY HEAD HURTED, SHOULDERS AND BUT. BUT FOR ME THE SEAT BELT I FELT IT LOCK INSTANTLY. THIS IMPACT WAS FROM BEHIND WHILE I WAS WAITING FOR THE LIGHT TO TURN GREEN. THE ACCIDENT WAS HURTFUL BUT NOT TO SERVER OF A TOTAL LOST ON MY END. MY DAUGHTER DID GO TO THE HOSPITAL. THIS IS WHY IT CONCERNS ME.
