Results of a direct-observation study of seat belt use in Michigan conducted in December, 1985, were compared with results of previous surveys in December, 1984; April, 1985; and July, 1985. The current survey observed a probability sample of 17,500 occupants in 12,106 cars and light trucks between December 2 and December 21. Despite the recent decrease, belt use remains higher than it was before the mandatory use law took effect (43.0% in December, 1985, versus 19.8% in December, 1984).
