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 Pennsylvania, bicycles, motor scooters, skateboards, and similar modes of transportation are subject to specific regulations to ensure safety on public streets, highways, and roads. Bicyclists are required to follow the same traffic laws as motor vehicles, including obeying traffic signals and signs. They must ride in the direction of traffic and use bike lanes where available. Helmets are recommended for all riders but are mandatory for cyclists under the age of 12. Motor scooters must be registered and riders must have a valid driver's license; helmets are required for riders and passengers under 21. Electric scooters are regulated by local ordinances, which vary by city. Skateboards are typically not allowed on roads and are governed by municipal ordinances that dictate where they can be used. Speed limits for these modes of transportation are generally the same as for motor vehicles, unless otherwise specified by local laws. Operating any of these modes of transportation under the influence of alcohol or drugs is illegal and subject to the same DUI laws as motor vehicles. It's important for operators to check both state statutes and local ordinances for the most current regulations in their area.
