Results of a direct-observation study of seat belt use in Michigan conducted in April, 1986, were compared with results of previous surveys in December, 1984; April, 1985; July, 1985; and December, 1985. The current survey observed a sample of 17,776 occupants in 12,191 cars and light trucks between March 31 and April 19, 1986. The main finding was that use of seat belts changed little between December, 1985, and April, 1986. Restraint use among all motorists observed was 43.7% in April, 1986, compared to 43.0% in December, 1985. As in previous surveys, restraint use varied by region of the state. Despite the absence of an increase in restraint use from December, 1985, to April, 1986, belt use remains significantly higher than it was before Michigan's mandatory use law took effect.
