80. Motorcycle
A motorcycle is a motor-powered vehicle with two wheels, with or without a sidecar. Motorcycles include many different types and sizes of vehicles designed for road travel, recreation, touring or other purposes.
Motorcyclists should maintain full control of the motorcycle, obey the applicable traffic rules and use appropriate protective equipment. Licensing, helmet, equipment and road-use requirements vary between countries.

Are motorcycle helmets mandatory in every US state?
No. Helmet laws are made by the individual states. Some cover all riders and passengers, while others are age- or category-specific. Check the rules along your route rather than relying on one nationwide rule.
