Abstract
Motorcycle use brings increased risk to the operator simply by the nature of the vehicle. When a crash occurs, the threat of injury or death is magnified by physical exposure compared to that of other vehicle occupants. Detection and gap/speed judgments by other motorists present additional hazards to the users. In this study, motorcycle crashes in North Dakota are examined using crash data from 2002 to 2012. Additional information regarding motorcycle conspicuity and rider training and education is presented as a basis for efforts to guide crash prevention. (Author/publisher)
