Motor Vehicle Use Maps (MVUM)
Current Situation - The 2014 MVUMs remain in effect. Comments received will be used in the preparation of a future version of the MVUM. The comment sheet can also be used to provide road specific input for future project development efforts (future Transportation Analysis and NEPA related to roads).
Motor Vehicle Use Maps are available for the 2.1 million acre Shasta-Trinity National Forest. Motor Vehicle Use Maps are the official map for designating all roads, trails and areas available for public motorized travel on the Shasta-Trinity National Forest. While other maps are available for trip planning purposes, the MVUM is the official map indicating where motor vehicle use is legal on the Shasta-Trinity National Forest.
The Motor Vehicle Use Map is a requirement of the 2005 Final Travel Management Rule and is a product of the 1995 Shasta-Trinity National Forest Land and Resource Management Plan, as amended and travel management decisions on each Ranger District.
The MVUM displays National Forest Transportation System (NFTS) routes (roads and trails) or areas designated as open to motorized travel. The MVUM also displays allowed uses by vehicle class (e.g. highway-legal vehicles, vehicles less than 50 inches wide and motorcycles, seasonal designations, and provides information on other travel rules and regulations).
If a route is not shown on the MVUM, then it is not open to public motor vehicle travel. Routes designated for motorized use may not always be signed. It is the user’s responsibility to reference the MVUM in order to determine if they are on a route designated for the motor vehicle they are using. The MVUM will be updated annually to correct mapping errors or discrepancies and update travel decisions.
The MVUM is a black and white map with no topographic features. It is a map for legal designations of where you can travel with various motorized vehicles. For additional reference, it is best used in conjunction with a forest transportation map, forest visitor map or other detailed map.
The MVUM is free to the public at each forest office. The MVUM is available on this website and sections of it may be printed from your home computer. The map is fully searchable using the find window at the top of the map. Type in the route number or other text and you will be taken to each occurrence of that number or text.
