Seat belt was able to save me in the accident but air bags never deployed after hitting concrete almost head on. Air bag sensor malfunctioned and light turned in but did not deploy.
Driver's side door was struck by a chevy astro cargo van going approximately 70 miles per hour on the highway (d. C. Beltway) and the side airbags did not deploy. A maryland state trooper (who saw the car) and the mechanic at the auto repair shop where the vehicle was towed both said the airbags should have deployed. Both said if the airbags had worked, the driver would not be as severely injured.
