Motorcycle safety is the study of the risks and dangers of motorcycling, and the approaches to mitigate that risk, focusing on motorcycle design, road design and traffic rules, rider training, and the cultural attitudes of motorcyclists and other road users.
Riding motorcycles on public roads carries several times the risk of riding in cars, which themselves are more risky than public conveyances like buses and trains. The human factors of motorcycle crashes are roughly equal between rider behavior and the actions of drivers sharing the roads. Technological changes, especially in the latter half of the 20th century, have made significant improvements in motorcycle safety. Serious research into motorcycle safety began in the US with the Hurt Report in 1981, followed by major studies in Europe and others. The main result of this research has been a greater emphasis on rider training and stricter licensing requirements. The US military recognized the need for their own focused motorcycle rider education in response to significant off-duty injuries of military personnel.
