This paper provides an accident investigation protocol for the examination of a vehicle having an inflatable restraint (air bag) system. The topics covered are beyond what is normally required for a routine vehicle examination. Included are points on administrative preparation, such as safety precautions, information research, logistics and equipment preparation, and photo documentation equipment. The examination protocol covers exterior damage, under hood inspection, and examination of the vehicle interior. Passenger compartment integrity, intrusion, occupant contact, evidentiary transfers, seating, seat belts, and components of the inflatable restraint system are addressed, along with component removal and recovery, for shipment to a laboratory.
