Overall front seat outboard passenger shoulder belt use in the United States was estimated at 67 percent in December 1999 and at 71 percent in June 2000, according to results obtained from Mini-National Occupant Protection Use Surveys (MiniNOPUS) conducted by the National Highway Traffic Safety Administration (NHTSA). Estimates from the June 2000 MiniNOPUS also showed that overall shoulder belt use in states with standard enforcement (primary) seat belt laws was 77 percent and 63 percent in states without standard enforcement laws. This Research Note presents results from these two MiniNOPUS as well as provide a chronology of overall shoulder belt use from all nationwide shoulder belt use surveys conducted by NHTSA. (A)
