A direct observation survey of safety belt use in Michigan was conducted in the fall of 2003. In this study, 11,723 occupants traveling in four vehicle types (passenger cars, sport-utility vehicles, vans/minivans, and pickup trucks) were surveyed between August 28 and September 10, 2003. Belt use was estimated for all commercial/noncommercial vehicle types combined (the statewide safety belt use rate) and separately for each vehicle type. Within and across each vehicle type, belt use by age, sex, road type, day of week, time of day, and seating position were calculated. Statewide belt use was 84.8 percent. This rate represents the highest level of statewide safety belt use ever observed in Michigan. |
