The two components of NHTSA's occupant protection program have reinforced each other. FMVSS 208 offered a "choice" between automatic protection and safety belt laws, and therefore, became the catalyst for the adoption of state "buckle-up" laws. In 1983, prior to FMVSS 208 (as amended), no state had a belt use law. Currently, 49 states plus the District of Columbia and Puerto Rico have safety belt use laws. In addition, national safety belt use has risen dramatically from 14 percent in 1983 to 68 percent as of December 1995
CHEST -- The air bag plus lap-shoulder belt provided the only statistically significant injury protection to drivers at the moderate injury level, and significant benefits at the serious level. The estimated effectiveness of the manual lap-shoulder belt system in reducing moderate chest injury was 14 percent, indicating that drivers experienced slightly less risk of an moderate chest injury (but not significantly so) if they wore their lap-shoulder belts compared to being unrestrained. However, at the serious injury level, manual lap-shoulder belt effectiveness increased to a significant 54 percent. The air bag alone was associated with a (nonsignificant) increase in the risk of moderate chest injury; at the serious level, the air bag provided some protection (18 percent reduction in risk). One possible explanation for the large benefit of the air bag plus lap-shoulder belt at the moderate level may be that the restraining effect of safety belt systems, inhibiting drivers from moving forward in a crash, may result in fractured ribs or sternum, bruised diaphragm, or minor bruises and lacerations to abdominal organs, all classified as AIS 2 injuries. The addition of the air bag to a lap-shoulder belt may serve to cushion the driver's forward movement, resulting in the driver "striking" the safety belt with less force and thus, a lesser chance of these AIS 2 chest and abdominal injuries.
