Motor Vehicle Use Map

Gifford Pinchot National Forest Motor Vehicle Use Map (MVUM) Atlas

Graphic: Road map.The MVUM is the implementation tool of the Travel Management Rule of 2005 (Federal Register Vol. 70. No 216, 2005), which required each National Forest to designate a system of roads and trails open to motorized vehicles.  In 2011, we introduced the MVUM as a set of 11 maps to cover the forest. We used your feedback to improve the format and to fix inaccuracies.

About the Gifford Pinchot National Forest Motor Vehicle Use Map (MVUM)

The Motor Vehicle Use Map shows the roads, trails and areas where you can legally drive your wheeled motor vehicles. These roads, trails and areas are designated by type of motor vehicle allowed and the allowable season of use. All motor vehicle operators are required to know and follow the regulations displayed on the MVUM when driving a motor vehicle on the forest. 

National Forest System Roads that allow motor vehicle use two primary designations: 1) Roads Open to Highway Legal Vehicles Only and 2) Roads Open to All Vehicles

Some examples of the vehicle types that are highway legal are:  passenger cars, pickup trucks, SUVs and motorcycles that by state law are licensed for general operation on all public roads within the state.

Some examples of vehicles that are not highway legal include: ATVs, UTVs (side by sides), off road motorcycles, golf carts and any other motor vehicle that by state law is not licensed for general operation on all public roads in the state.

A road that is designated as "open to all motor vehicles" allows any motor vehicle both licensed and unlicensed for general operation on all public roads in Washington state.

Refer to the appropriate Motor Vehicle Use Map to determine the allowed motor vehicle use for a specific National Forest System road, trail or area.  These maps are available at all National Forest offices and on all National Forest web sites.  Call your national forest if you have questions.

The MVUM outlines where to legally drive wheeled motor vehicles and it displays designated roads and trails suitable for motorized use by type of vehicle and time of year.

  • Visitors may legally drive only on the roads and trails identified on the MVUM. Operation of unlicensed vehicles on Forest roads and motorized cross-country travel off of designated routes are prohibited on the GPNF.
  • The MVUM displays regulations on road and trail access for all types of wheeled motor vehicles, including street legal and off highway vehicles. 
  • The MVUM is free of charge and can be obtained from GPNF offices and on the website.
  • The MVUM is issued annually – we use your feedback to improve the product each year. 
  • Within 150 feet of many roads identified on the MVUM, visitors may use motor vehicles along existing routes to reach dispersed campsites. 
  • Snowmobile use is not regulated by the MVUM.

Each National Forest in the country requires visitors to know and follow the regulations displayed on their MVUM. The MVUM is designed to allow appropriate access for wheeled motor vehicles to protect forest resources from damage caused by unmanaged motorized use. The Gifford Pinchot National Forest utilized existing management direction to produce the MVUM. Therefore, the map does not represent any new changes in existing motorized access on the GPNF. The MVUM is updated annually to insure it accurately displays changes in current conditions and management direction.

The MVUM Atlas covers all areas of the Gifford Pinchot National Forest. Visitors may pick up a free Motor Vehicle Use Map (MVUM) set at Forest Headquarters, Ranger Districts, and Mount St. Helens National Volcanic Monument offices. You may also download a copy of the MVUM Atlas from this webpage. Forest Visitor Maps and District Maps should be used in conjunction with the MVUM Atlas to help you navigate the Forest. Your feedback is important to us. Call us or visit your local ranger district with your questions or comments. 

State Law and All Terrain Vehicles (ATV's)

The new state law Engrossed Substitute House Bill 1632 (ESHB 1632) does not allow general operation of wheeled ATVs on all public roads in the state even if they are licensed. By Forest Service policy, roads designated as “Open to Highway Legal Vehicles Only” are open to motor vehicles licensed under state law for general operation on all public roads within the state. Therefore wheeled ATVs are not highway legal vehicles under Forest Service policy. The bill has no direct effects on policies or access decisions for public lands. The MVUM displays roads and trails where ATVs are currently legal to operate
