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 New Jersey, bicycles, motor scooters, skateboards, and similar modes of transportation are subject to specific regulations. Bicyclists are required to follow the same traffic laws as motorists, which includes obeying traffic signals and signs, and riding in the same direction as traffic. New Jersey law mandates the use of helmets for bicycle riders under the age of 17. Motor scooters, which can be either electric or gas-powered, may have different regulations depending on their motor size and capabilities; some may require registration, insurance, and a valid driver's license to operate. Skateboards are typically regulated at the municipal level, with some cities and towns restricting their use on public streets and sidewalks. Speed limits for these modes of transportation are generally the same as for motor vehicles on the same roadways, unless otherwise posted. All riders are subject to DUI laws and cannot operate any vehicle under the influence of alcohol or drugs. It's important for riders to check local ordinances for specific rules that may apply in their area, as these can vary significantly.
