SAFETY BELT INTERLOCK SYSTEM USAGE SURVEY
The research measures the effectiveness of various systems to increase safety belt usage. The objectives are: (1) To determine if the 1975 warning system issued in response to P.L. 93-492 is effective in increasing usage; (2) to ascertain drivers' reactions to this and other systems on 1975 model cars; and (3) to continue to monitor safety belt usage in the general traffic population. Results show that the 1975 warning system is not very effective. Most effective is a system that includes (1) a reminder light that goes on and stays on until the belt is fastened, and (2) a sequential logic circuit that requires to first be seated and second to buckle the belt. Drivers' attitudes toward the use of safety belts, and perceived comfort of both the lap belt and shoulder harness are also key factors which are correlated with usage.
