The global fleet of powered two-wheelers (PTWs) is constantly increasing. In many countries, motorcycles, scooters and mopeds play a significant role in mobility, particularly in many of the world’s large cities. As such, PTWs are becoming an important component of the transport system.

"Relative to passenger cars, two- and three-wheeled vehicles such as motorcycles, mopeds, and seated motor scooters (50cc or less) are associated with a higher risk for fatalities and serious injuries in the event of a traffic crash, as they do not offer the protection of an enclosed vehicle or include other safety enhancement features such as occupant restraints. BTSCRP Research Report 11: Improving Rider Safety for Mopeds and Seated Motor Scooters of 50cc or Less, from TRB's Behavioral Traffic Safety Cooperative Research Program, provides state highway safety offices and other safety organizations with information and tools to help improve moped and seated motor scooter rider safety."--Publisher's website
