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 Idaho, bicycles, motor scooters, skateboards, and similar modes of transportation are subject to specific regulations when operated on public streets, highways, and roads. Bicyclists are generally required to follow the same traffic laws as motor vehicle drivers, such as obeying traffic signals and signs. Idaho's bicycle laws allow cyclists to use the roadway, and they must ride as close as practicable to the right-hand curb or edge of the roadway, except under certain conditions like when overtaking another bicycle or preparing for a left turn. Motor scooters may require registration and a valid driver's license to operate, depending on their engine size and maximum speed capability. Helmets are not mandated by state law for bicycle riders of any age, but local ordinances may require them, especially for minors. Skateboarders are often regulated by municipal ordinances, which can vary widely, including restrictions on where skateboards can be used. Regarding alcohol or drugs, Idaho prohibits operating any vehicle, including bicycles and motor scooters, while under the influence. The state's DUI laws apply to all vehicles, and penalties can include fines, license suspension, and even jail time. It's important for operators of these alternative modes of transportation to check local ordinances for specific rules in their city or town.
