Types of ATVs

States often use different terms to define Off Highway Vehicles (OHV) or All-Terrain Vehicles (ATV).

In Oregon, laws were written using the term All-Terrain Vehicle which encompasses all types of vehicles including motorcycles, 3 wheelers, quads, side-by-sides, sand rails, trucks and SUVs.

There are legal definitions for each type of vehicle and the rules can be different for each for things such as age of operator and where each type of vehicle can be driven. See below for the specific rules.

Operators with a suspended or revoked driver's license may not operate any Class of ATV.

Class I ATVs are known as four-wheelers, quads, 3-wheelers. They can be 2 or 4 wheel drive. They also include 6x6 ATVs. Polaris Ace is considered a Class IV since it has a steering wheel and seat.

  • Titles. Titles are not required for Class I ATVs, but a title is often required by the bank or insurance company, to finance or insure a vehicle. Contact Driver and Motor Vehicle Services  for vehicle titling information. A title also helps prove ownership if the vehicle is stolen. Class I ATVs cannot be registered to get a license plate.

  • Equipment. Meet the safety equipment standards for off-road vehicles. Including seat and foot pegs or floor pan which protects the all rider's feet. Must also have working brakes and a secure fuel tank. Must have a flag when operating on sand and headlights and taillights when operating after dark.

  • Mufflers. Adequate  muffler to limit sound emissions to 97 db. Spark arrester during fire season.

  • Fire Season. During fire season, there may be extra restrictions on equipment and where you can drive. This depends on the land owner and the timing of the year. As a general rule, during fire season you should have a shovel and fire extinguisher for every vehicle when in the forest. You will also need a muffler and an exhaust system in good working order, which prevents sparks. Some areas will restrict use to improved roads free for vegetation.
