MOTORCYCLE CRASH STUDY IOWA, 1980-1982

This report is a continuation of a study of motorcycle crashes in the state of Iowa. The main objectives are to study trends and to determine the circumstances surrounding motorcycle crashes. Some highlights of the findings presented in this report are as follows: motorcycle registrations have increased and comprise 8.9 percent of the total motor vehicle registrations in the period 1980-1982, while motorcycle fatalities accounted for 13.1 percent of the total motor vehicle traffic fatalities during the same period; in the period 1980-1982, 59.3 percent of the drivers in fatal motorcycle crashes were under the age of 25; the collision of a motorcycle with another vehicle accounted for 59.2 percent of the motorcycle fatal crashes, while single motorcycle crashes were responsible for 40.8 percent; about 85.7 percent of all motorcycle crashes of this three year period occurred during the months of April through September; alcohol was found to be a major contributing factor in fatal motorcycle crashes (41.2 percent of the total); and fewer motorcycle fatalities occurred during the 10 months a helmet law was in effect than occurred in comparable time intervals before or after repeal. Many more statistics and conclusions are included in this report.
