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 Tennessee, 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 must ride as close as practicable to the right-hand curb or edge of the roadway, except when passing, making a left turn, avoiding hazards, or when the lane is too narrow to share. Tennessee law mandates that all bicycle riders under 16 years of age must wear a helmet. For motor scooters, which include electric or gas-powered scooters, operators must have a valid driver's license, and scooters must be registered if they exceed certain speed capabilities or engine sizes. Helmets are required for riders under 18 or if the scooter can exceed 30 mph. Skateboards are typically regulated by local ordinances rather than state law, and regulations can vary widely by city or town. Regarding alcohol or drugs, it is illegal to operate any of these modes of transportation while under the influence, similar to the laws for operating a motor vehicle. It's important to check local ordinances for specific rules that may apply to these alternative modes of transportation, as they can impose additional requirements or restrictions.
