Identification of Risk Factors Associated with Motorcycle-Related Fatalities in Ohio

Abstract

Ohio crash data for 2003–2007 were used to investigate the odds of a motorcyclist being fatally injured in a crash and the risk factors involved. The results show that risk factors for fatality/severe injury significantly increase when the following circumstances apply: the motorcyclist is a female, being the motorcycle rider, use of excessive speeding, use of alcohol and/or drugs, riding without a helmet, being involved in a single-vehicle crash or at a nonintersection location, crashing on horizontal curves or on graded segments, and on major roadways. To reduce the number of fatal crashes, this study indicates that the dangers of excessive speed and operating a motorcycle while intoxicated must be fully stressed to the public and both require an elevated enforcement. The enactment of an Ohio universal helmet law is particularly recommended.
