Mopeds
A moped is a vehicle which looks and handles essentially like a bicycle and is propelled by a small engine which produces not more than 2 gross brake horsepower, has a displacement of not more than 50 cubic centimeters and is capable of a maximum speed of not more than 30 miles per hour on a flat surface with not more than 1 percent grade in any direction when the motor is engaged. (NRS 486.038)
You must have a Class C or higher driver license to drive a moped or motorized bicycle on a public street. You do not need a Class M license. Mopeds do not require insurance or vehicle registration. If the moped produces more than 2 gross brake horsepower, or has a displacement of more than 50 cubic centimeters (50 cc), or is capable of exceeding thirty miles per hour (30 mph) on a flat grade, it is considered a motorcycle and you must have a Class M license, registration and insurance.
Mopeds must have the same safety equipment (lights, mirrors, etc.) as a motorcycle in order to be driven on any public street. See the Motorcycle Equipment Tip Sheet. Other vehicles with a small engine are considered off-road motor vehicles and may not be operated on public streets.

Any motorized vehicle which does not have the normal safety equipment such as lights and mirrors or is not built to federal vehicle standards is an off-road vehicle and is restricted to off-road use only. This includes all-terrain vehicles, pocket bikes, motorized scooters and snowmobiles.
Nevada does not title or register off-road vehicles for on-road use. If a vehicle was manufactured and designated for “off-road” or “non-road” use only, it may not be registered for use on Nevada public streets or highways.
If a vehicle is designated for off-road or non-road use it may not be converted for on-road use. The designation for off-road use is usually indicated in ownership documents, the owners manual or by a U.S. DOT label attached to the frame of the vehicle.
There are no driver license or minimum age requirements for off-road vehicles. You may not drive them on any public street. City and county governments may designate small portions of public streets for access to or from off-road areas only. (NRS Chapter 490)
