Is a Side-by-Side Considered a Motor Vehicle in the US?

In the United States, a side-by-side (also known as a Utility Task Vehicle (SXS) or Recreational Off-Highway Vehicle (ROV)) is a motor vehicle (because it is powered by an engine or electric motor), but it usually falls under "off-highway motor vehicles (classified as an off-highway vehicle (OHV) or SXS/ROV)" and is not an automobile that is allowed on public roads by default; whether it can be driven on public roads depends on state laws and regulations as well as modifications/registration status.

• On private land, off-road parks, forest trails, and farms: It is usually regulated as an OHV / SXS / ROV rather than a standard automobile.

• On public roads: It can only be legally driven on the road if it meets state requirements—such as registration, insurance, driver's license, headlights, taillights, horn, mirrors, license plate, etc.; and it is generally prohibited on interstate highways.

• Buying a vehicle, purchasing insurance, or signing a contract: You should look at the specific definitions in the documents; different states and insurance companies may refer to it as SXS, SxS, ROV, OHV, or off-road vehicle respectively.

State Classifications for Street-Legal SXSs

In the United States, regulations allowing side-by-side vehicles (SXS) to be modified for street use vary widely across states. Although federal highway law strictly prohibits driving SXSs on interstate highways nationwide, individual states control local road access through three main categories:

Group 1: Statewide Road Registration

These states offer a direct, statewide registration pathway that allows you to title, license, and drive a modified SXS on most secondary public roads:

1. Arizona (permits road registration using standard equipment)

2. Montana (allows registration for highway use without strict inspection/emissions requirements)

3. South Dakota (registers SXSs with an engine displacement over 200cc under motorcycle driver's license laws)

4. Utah (registers under specific street-legal all-terrain vehicle/utility vehicle regulations)

5. West Virginia (permits statewide multipurpose vehicle registration)

6. Wyoming (allows street registration for multipurpose vehicles)

Group 2: Restricted Statewide Road Access

These states allow SXS vehicles onto public roads without giving them full highway access—typically restricting SXSs to county roads, roads posted under 45–55 mph, or secondary highways:

• Alaska (permitted on roads posted at 45 mph or below, except in major cities where prohibited)

• Georgia (allows registered multipurpose off-road vehicles to be driven on county roads)

• Idaho, Iowa, Kansas, Minnesota, Missouri, Nevada, North Carolina, North Dakota, Oklahoma, Tennessee, Washington

Group 3: Local Approval Only / Strictly Restricted

States like California, New York, Delaware, Connecticut, and Pennsylvania do not offer direct statewide road registration services. In these states:

• SXSs (multipurpose off-road vehicles) are restricted to off-road trail riding, agricultural work, or brief road crossings.

• Certain states (such as Texas, Ohio, Kentucky, New Mexico) only permit limited road use if local municipalities or counties explicitly pass ordinances to open specific roads.

Specific Street-Legal Equipment Requirements

To convert a factory-manufactured side-by-side vehicle into a street-legal vehicle, state laws typically require a street-legal conversion kit.

Administrative Requirements

Title & DMV Registration: The UTV must hold a valid state title or MCO (Manufacturer's Certificate of Origin) and be registered with the DMV as a street-legal vehicle or multipurpose vehicle.

 Auto Liability Insurance: Off-road recreational insurance is insufficient to cover highway driving. Once the vehicle is registered and receives a license plate, you must purchase the minimum motor vehicle liability insurance required by your state.
