A direct observation survey was conducted in December, 1984, of 17,568 motor vehicle occupants at a carefully selected probability sample of 240 intersections throughout the State of Michigan. The sample was designed to adequately represent all regions of the state. Differential restraint use was examined by age, sex, seating position, time of day, day of week, type of roadway, weather conditions, vehicle type and size, and region of state. Use of occupant restraints was higher in December, 1984 than August, 1983, when an earlier survey was conducted. As of July 1, 1985, all drivers and front seat passengers traveling in Michigan will be required by law to be restrained. Results of the current survey will function as a baseline from which the effects of the law will be measured. Additional survey waves are planned for 1985 and 1986.
