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 Kentucky, bicycles are legally considered vehicles, and cyclists have the same rights and responsibilities as motorists. They are required to obey all traffic laws, signals, and signage. Bicyclists must ride as close to the right side of the roadway as practicable, and if a bike lane is present, they should use it. Helmets are not mandated by state law for bicycle riders, but local ordinances may require them, especially for minors. Motor scooters and electric bikes are subject to similar rules as bicycles, but additional regulations may apply, such as age restrictions and helmet requirements for certain motorized scooters. Skateboards are typically not allowed on public streets and highways, but local ordinances can vary. Speed limits for these modes of transportation are generally the same as for motor vehicles, unless otherwise specified. Licensing requirements for bicycles and skateboards do not exist, but motor scooters may require a valid driver's license or a moped license. Operating any of these modes of transportation under the influence of alcohol or drugs is illegal and subject to the same DUI laws that apply to motor vehicle drivers.
