Low Power Scooters
A "low‑power scooter" is a self‑propelled vehicle with no more than three wheels in contact with the ground, no manual clutch, and either a cylinder capacity under 50 cubic centimeters if powered by internal combustion, or a wattage under 4,476 watts if electric‑powered.
In Colorado, an operator of a low‑power scooter is required to have a valid driver license. Registration for a low‑power scooter is evidenced by a numbered decal on the frame, with registration lasting for three years. In order to register a low‑power scooter, the owner must have a motor vehicle insurance policy or a certificate of self‑insurance. Low‑power scooters may not drive on the interstate system (except where bicycles are allowed) or on any limited‑access road of the state highway system. Persons under the age of 18 may not operate or ride on a low‑power scooter without a protective helmet. Unless wearing a helmet with eye protection, all persons must wear eye protection when operating a low‑power scooter on public highways. Local authorities may regulate low‑power scooter operation under their jurisdiction.
