I WAS DRIVING NORTHBOUND ON A 3 LANE MAIN ROAD (2 LANES GOING ONE WAY, 1 LANE GOING THE OTHER WAY) AT ABOUT 40 MPH. WHILE COMING UP TO A T-INTERSECTION (I HAD THE RIGHT OF WAY, THE SENTRA HAD A STOP SIGN) ABOUT 20 TO 30 FEET FROM CROSSING THE INTERSECTION, THE SENTRA PROCEEDED TO CROSS MY LANES TO MAKE HER LEFT TURN. AS I TRIED TO AVOID THE ACCIDENT I ENDED UP HITTING HER SENTRA HEAD ON. AFTER THE IMPACT MY AIRBAGS DID NOT DEPLOY. AS FOR HER SENTRA THE IMPACT WAS ON THE FRONT LEFT TIRE SO NO AIRBAGS DEPLOYED IN HER CAR. I HAVE A 2000 FORD F-150 AND HIT HER HEAD ON....BUT NO AIRBAGS DEPLOYED. COULD THIS HAVE BEEN A POSSIBLE DEFECT ON MY TRUCK. I HAD PICTURES TAKEN MINUTES AFTER THE ACCIDENT. *TR
