Abstract

The use of automatic safety belts among motorists throughout the state of Michigan was examined in May 1990 as part of a broader direct-observation survey to measure compliance with Michigan's mandatory safety belt use law. Use of the two most common types of automatic belt systems were measured: the nonmotorized detachable three-point lap and shoulder belt system and the motorized shoulder belt with manual lap belt system. A total of 828 drivers and 237 front-right passengers were observed with automatic belt systems between April 30, 1990 and May 24, 1990. Use of nonmotorized detachable three-point lap and shoulder belt systems was 74.3%. Lap belt use of motorized shoulder and manual lap belt systems was 79.2%. Of all motorized shoulder belt and manual lap belt systems observed, 97.4% had the shoulder belts connected.
