A low‑speed electric vehicle (LSEV) is a vehicle that:
- is self‑propelled utilizing electricity as its primary propulsion method;
- has at least three wheels in contact with the ground;
- does not use handlebars to steer; and
- displays a VIN pursuant to state law
LSEVs can only operate on a roadway that has a speed limit of 35 mph or less, but they may cross a roadway with a speed limit of greater than 35 mph at an at‑grade crossing. LSEVs are not allowed on limited‑access highways.
LSEVs can operate on or cross a state highway with a speed limit of 40 mph if:
- the roadway's lane width is eleven feet or greater;
- the roadway has two or more lanes in either direction; and
- the Colorado Department of Transportation (CDOT) determines, in consultation with local government and law enforcement, upon the basis of a traffic investigation, or survey, that the operation of LSEVs on the roadway poses no substantial safety risk or hazard to motorists, bicyclists, pedestrians, or other persons.
LSEVs are titled and registered as tax class C vehicles, and registration fees for LSEVs are the same as other passenger vehicles of the same size and weight.
Class B low‑speed electric vehicles. Class B LSEVs are motor vehicles with speed capabilities of 25 to 45 mph, and are only permitted to be on roads with 45 mph. They may cross a roadway that has a speed limit above 45 miles per hour in an at‑grade crossing.
The state Division of Motor Vehicles (DMV) will not register or issue a title for class B LSEV until the U.S. Department of Transportation adopts motor vehicle safety standards for LSEVs that authorize operation at greater than 25 mph and less than 45 mph.
