WE WERE HEADING EAST ON A CITY STREET WHEN WE CAME TO AN INTERSECTION. THE LIGHT WAS GREEN SO WE CONTINUED THROUGH THE INTERSECTION. THERE WAS ANOTHER CAR HEADING WEST ON THE SAME STREET AND TURNED LEFT DIRECTLY IN FRONT OF US AT THE INTERSECTION. WE WERE TRAVELING BETWEEN 40-45 MPH. WE COULD NOT AVOID THE CAR THAT TURNED IN FRONT OF US. WE HIT THE SIDE OF THE SECOND VEHICLE (THE ONE TURNING SOUTH) HEAD ON WITH OUR VEHICLE. THE AIRBAGS IN OUR VEHICLE DID NOT DEPLOY. BOTH THE FIREMAN AND SHERIFF ON THE SEEN COMMENTED ON THE FACT THAT OUR AIRBAGS SHOULD HAVE DEPLOYED. ALSO AFTER OUR VEHICLE WAS TOWED BACK TO THE DEALERSHIP, THE HEAD MECHANIC WAS SHOCKED THAT THE AIRBAGS DID NOT DEPLOY. OUR VEHICLE HAS A BENT FRAME ON BOTH SIDES AND HAS BEEN TOTALED.
