Laws governing the operation of bicycles, motor scooters (electric or gas powered), skateboards, and other modes of transportation on public streets, highways, and roads vary from state to state, and among cities and towns (municipal ordinances).

Some of the important laws governing these alternative modes of transportation include proper roadways and lanes for operation; speed limits; required safety precautions (helmets, etc.); application of traffic laws; license requirements; and the application of laws regarding being under the influence of alcohol or drugs.

In Michigan, bicycles are legally considered vehicles, and cyclists have the same rights and responsibilities as motorists. Bicyclists must obey all traffic signals and signs, signal their turns, and ride with the flow of traffic. There are no state-wide laws mandating helmet use for bicyclists of any age, but some local ordinances may require helmets for younger riders. Motor scooters and mopeds must be registered with the Secretary of State, and operators must have a valid driver's license or moped license. Helmets are required for moped riders under the age of 19. Electric skateboards are allowed on public roads with a speed limit of 25 mph or less, and the rider must be at least 12 years old. Skateboarders and electric scooter users must yield the right-of-way to pedestrians and are subject to local ordinances, which can vary widely. Operating any of these modes of transportation under the influence of alcohol or drugs is illegal and subject to the same DUI laws that apply to motor vehicle drivers.
