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 Arizona, bicycles are considered vehicles under the law, and cyclists have the same rights and responsibilities as motorists. They must obey all traffic signals and signs, ride in the same direction as traffic, and use bike lanes where available. Helmets are not required by state law for bicyclists of any age, but local ordinances may require them for minors. Motor scooters and electric bicycles are subject to similar rules as bicycles, but they may have additional requirements such as minimum age limits, licensing, and registration depending on their speed and power. Skateboards are not typically allowed on public streets and highways, but local ordinances may permit them on certain roadways or areas. Speed limits for these modes of transportation are generally the same as for motor vehicles unless otherwise posted. All operators are subject to DUI laws and can be charged if operating under the influence of alcohol or drugs. It's important to check local ordinances as they can impose additional regulations on the operation of these alternative modes of transportation.
