What are LUVs?
Because we’re talking about a group of vehicles that fall into cracks in the regulatory system, there’s no set definition, but here’s some of what we mean when we use the term: They’re vehicles larger than a bike, smaller than a car, and less powerful than a motorcycle.
They have no set number of wheels, but most have two to four. They can assist the pedaling of a human rider, or be fully motorized and use an accelerator pedal or hand throttle. Their electric motors are upwards of 750 watts (below that, they can probably fall into e-bike rules).
They can be used for solo trips, moving passengers, or cargo and delivery. They can be deployed as shared-use for the public, private fleets, or personally owned.
The Federal Baseline
NHTSA’s definition of Low-Speed Vehicles is pretty simple:
- Four-wheeled motor vehicles under 3000 lbs. curb weight
- Top speed over 20 mph but under 25 mph
- Basic safety requirements like lights, signals, windshields, mirrors, and seatbelts, but exempt from full crashworthiness standards
- Have a unique VIN
Not all small or slow vehicles are LSVs…
Any vehicle that exceeds the weight or speed limits of LSVs, even by a few pounds or mph, is considered a full motor vehicle, and must comply with much more stringent crashworthiness and equipment standards.
This leaves out innovative vehicle types safely used elsewhere in the world, like quadricycles, kei cars, and other compact urban and utility vehicles
… but some are LSVs inadvertently
Since the federal rules rely on wheel count, speed, and the presence of a motor, but there’s no minimum weight, some four-wheeled vehicles get caught in the LSV definition that don’t make much sense. Small four-wheeled vehicles may be classified as LSVs even if they are:
- Primarily human-powered
- Pedal-assist e-cargo bikes
- Lightweight and bike-like in use and level of protection
