Over the 6-year period, the number of motorcycles registered in Michigan increased by 45%; licensed motorcyclists increased by 8%; and motorcycle increased by 20%. The largest increases in licensed motorcyclists were among those aged 45-64. In 2002, there were 15.4 crashes per 1,000 registered motorcycles, an 18%decrease from 1997; and 5.9 crashes per 1,000 licensed motorcyclists, a 12%increase from 1997. The highest crash rate was among motorcyclists below age 19, and the lowest was among those over age 64. About 44%of crash-involved motorcyclists were not legally licensed to operate a motorcycle. The proportion of unlicensed motorcyclists among crash-involved motorcyclists by age, with the largest proportion among those below age 19. The number of fatal motorcycle crashes in which a driver had been drinking increased by 28%from 1997 through 2002, but the proportion of fatal crashes among had-been drinking crashes decreased fro 47%in 1997 to 29%in 2002. |
