OUR DAUGHTER WAS IN A 3 CAR ACCIDENT. THERE WAS BRIDGE CONSTRUCTION AND ALL OF A SUDDEN TRAFFIC WENT FROM MOVING AT HIGHWAY SPEED TO STOPPED. DIRECTLY AHEAD OF OUR DAUGHTER WAS A REFRIGERATOR TRUCK. OUR DAUGHTER WAS NOT ABLE TO STOP QUICKLY ENOUGH AND STRUCK THE BACK OF THE REFRIGERATOR TRUCK. THE SPEED LISTED ABOVE IS AN ESTIMATE. NO ONE IN THE OTHER VEHICLES WERE HURT, NOR DID THEIR CARS SUSTAIN REPAIRABLE DAMAGE. MY DAUGHTER'S CAR WAS STOPPING STRAIGHT AT THE POINT OF COLLISION AND STRUCK THE BACK OF THE TRUCK SQUARE. THE OFFICER AT THE SCENE SUGGESTED SHE BE CHECKED OUT IN THE ER. MY DAUGHTER SUSTAINED SOFT TISSUES INJURIES AND BRUISES. AFTER SOME TIME WITH THE CHIROPRACTOR SHE SHOULD BE FINE. MY QUESTION/CONCERN DEALS WITH THE AIR BAG SYSTEM. THE DRIVER KNEE AIRBAG DEPLOYED, THE STEERING WHEEL AIRBAG DID NOT. IS THAT POSSIBLE? ARE THERE SITUATIONS WHERE IT IS APPROPRIATE FOR THE LOWER BAG TO DEPLOY WITHOUT DEPLOYING THE STEERING WHEEL AIR BAG? THE SEAT BELT DID STOP HER, ALTHOUGH IT LEFT A LARGE RED MARK ON HER SHOULDER. IF THE SYSTEM WORKED CORRECTLY THAT IS FINE. WE WOULD LIKE TO HEAR FROM SOMEONE WITH EXPERTISE IN THIS AREA TO MAKE SURE THAT THERE IS NOTHING FAULTY IN HER CAR. IF NEEDED WE CAN SUPPLY PHOTOS TO SHOW THE EXACT DAMAGE. THE VEHICLE IS AT THE DEALERSHIP NOW FOR REPAIRS, SO THE MILEAGE IS A GOOD ESTIMATE. THANK-YOU FOR YOUR HELP.
