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 Indiana, 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 vehicles, including obeying traffic signals and signs. They should ride on the right side of the roadway and use bike lanes where available. Helmets are not mandated by state law for bicycle riders of any age, but local ordinances may require them, especially for minors. Motor scooters, which can be electric or gas-powered, may have different regulations depending on their speed capabilities. Scooters capable of speeds greater than 25 mph may be classified as motor vehicles and require registration, a driver's license, and insurance. Lower-speed scooters might have less stringent requirements. Skateboards are typically not allowed on roadways and are subject to local ordinances that may restrict their use to sidewalks or designated areas. 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 municipal ordinances for specific rules in their area.
