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 Illinois, bicycles are legally considered vehicles and are subject to many of the same traffic laws as motor vehicles. Cyclists must obey traffic signals and signs, signal turns, and follow right-of-way rules. There are designated bicycle lanes in many areas, and when not available, cyclists are to ride as close as practicable to the right-hand curb. Helmets are not mandated by state law but are highly recommended for safety. Motor scooters, which include electric or gas-powered scooters, are regulated differently. Riders must have a valid driver's license, and the scooters must be registered. Helmets are required for riders under the age of 18. Skateboards are typically governed by local ordinances rather than state law, and regulations can vary widely by municipality, often including restrictions on where skateboards can be used and sometimes requiring safety gear. DUI laws apply to all vehicles, including bicycles and motor scooters; operating any of these modes of transportation under the influence of alcohol or drugs is illegal. It's important for operators to check both state statutes and local ordinances for the most accurate and current regulations.
