A direct observation survey of safety belt use in Michigan was conducted. In this study, 12,690 occupants traveling in four vehicle types (passenger cars, sport-utility vehicles, vans/minivans, and pickup trucks) were surveyed between December 2 and 16, 2002. 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 rates by age, sex, road type, day of week, time of day, and seating position were calculated. Statewide belt use was 80.5 percent. When compared with the rate observed in September 2002, the current rate shows that safety belt use in Michigan has remained about the same. |
