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 Oregon, bicycles, motor scooters, skateboards, and similar modes of transportation are subject to specific regulations when operated on public streets, highways, and roads. Bicyclists are required to follow the same traffic laws as motor vehicle drivers, such as obeying traffic signals and signs. They must ride in the direction of traffic and are typically allowed to use bike lanes where available. Helmets are not mandated by state law for bicycle riders of any age, but some local ordinances may require them, especially for minors. Motor scooters and electric bikes must adhere to speed limits, which may vary depending on whether they are classified as motor-assisted scooters, mopeds, or motorcycles, each with different equipment and licensing requirements. Skateboarders are often restricted from riding in the streets and may be limited to sidewalks or designated areas, with local ordinances dictating specific rules. 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. It's important for operators to check both state statutes and local municipal ordinances for detailed regulations in their specific area.
