DIRECT OBSERVATION OF SEAT BELT USE IN MICHIGAN, JULY 1985

Results of a direct-observation survey of seat belt use in Michigan conducted in July, 1985 were compared with results of previous surveys in December, 1984 and April, 1985. The current survey observed a probability sample of 20,023 occupants in 12,263 cars and light trucks between July 17 and August 5. Use of restraint systems among motorists of all ages increased substantially between April and July, associated with a law that began requiring seat belt use among front-seat occupants on July 1, 1985.
