Commonly Used Terms

For easier reading, we may use three-letter acronyms to refer to vehicles.

Three types of OHVs: An ATV, OHM, and UTV
  • OHV: Off-Highway Vehicle. A two-, three-, or four-wheeled vehicle that has a motor and is designed for riding on unpaved surfaces. OHVs are also commonly known as ORVs.
  • ATV: All-Terrain Vehicle. A type of OHV with low-pressure, knobby tires designed for riding on unpaved surfaces. ATVs typically have four wheels. Three-wheeled ATVs are illegal in many states.
  • OHM: Off-Highway Motorcycle. A type of motorcycle equipped for certain off-road sports. These motorcycles may or may not be “street-legal.”
  • UTV: Utility Terrain Vehicle. A type of OHV where the driver and a passenger can sit side-by-side in the vehicle. They are most commonly known as UTVs (Utility Terrain Vehicle, Utility Task Vehicle, or just Utility Vehicle) or Side-by-Side Vehicles. UTVs are not designed for use on paved surfaces.
