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 Wisconsin, bicycles are legally defined as vehicles and cyclists have the same rights and responsibilities as motorists. Bicyclists must obey all traffic signals and signs, and they are required to use hand signals when turning or stopping. There are no statewide laws in Wisconsin mandating the use of helmets for bicyclists of any age, but some local ordinances may require them for younger riders. Motor scooters and electric scooters are subject to different regulations. Riders must have a valid driver's license, and scooters must be registered if they exceed certain power or speed thresholds. Helmets are not required for motor scooter riders over the age of 18. Skateboards are typically regulated at the local level, with ordinances varying by city or town. Skateboarders may be restricted from riding on certain roadways and may be required to wear safety gear. All users of these modes of transportation must adhere to speed limits and are subject to laws regarding operating under the influence of alcohol or drugs. It's important for individuals to check local ordinances for specific rules in their area, as they can vary significantly.
