Summary

This National Highway Traffic Safety Administration (NHTSA) fact sheet presents statistical data on motorcycle traffic safety in the United States for the year 2001, highlighting a significant increase in fatalities and injuries compared to the previous year. In 2001, 3,181 motorcyclists were killed and 60,000 were injured, representing a 10 percent increase in fatalities and a 4 percent increase in injuries over 2000 figures. Despite motorcycles comprising only 2 percent of registered vehicles and 0.4 percent of vehicle miles traveled in 2000, motorcyclists accounted for 8 percent of all traffic fatalities. The data indicates that per vehicle mile traveled, motorcyclists were approximately 21 times more likely to die and four times more likely to be injured than passenger car occupants. The report analyzes crash characteristics, driver behavior, and protective measures using data from the Fatality Analysis Reporting System (FARS) and the General Estimates System (GES). Methodological updates included a revised definition for speeding-related crashes and the adoption of multiple imputation to estimate missing blood alcohol concentration (BAC) values. The analysis covers national trends, state-specific fatality rates, and comparative statistics between motorcycles and other vehicle types such as passenger cars and light trucks. Key findings reveal that motorcycles are disproportionately involved in collisions with fixed objects and left-turning vehicles. In 2001, 28 percent of fatal motorcycle crashes involved a fixed object, compared to 17 percent for passenger cars. In two-vehicle fatal crashes, 36 percent involved a motorcycle passing a vehicle that was turning left. Driver impairment and licensing issues were prevalent; 39 percent of motorcyclists in fatal crashes were speeding, twice the rate for passenger vehicle drivers, and 27 percent operated with an invalid license. Alcohol involvement was also high, with 29 percent of fatally injured motorcycle operators having a BAC of 0.08 g/dl or greater, the highest rate among all vehicle types. Intoxication rates were particularly high in single-vehicle crashes (41 percent) and during weekend nights (58 percent). The significance of these findings underscores the critical role of helmet use and the risks associated with impaired operation. NHTSA estimated that helmets saved 674 lives in 2001 and could have saved an additional 444 if universally worn, noting that helmets are 29 percent effective in preventing fatal injuries and 67 percent effective in preventing brain injuries. However, helmet use among fatally injured operators declined from 54 percent in 2000 to 53 percent in 2001. The report concludes by detailing varying state helmet laws, noting that as of December 2001, only 20 states and the District of Columbia required universal helmet use, while three states had no requirements. The data serves as a baseline for understanding the disproportionate risk motorcyclists face and the potential impact of safety interventions.

Key finding

Motorcyclists were approximately 21 times as likely as passenger car occupants to die and 4 times as likely to be injured per vehicle mile traveled in 2000.
