Routes in the OwlsheadGPS Project that are designated by National Forests for motor vehicle use are fully depicted on their official USFS Motor Vehicle Use Maps (MVUM), which are available to view and download at:
The MVUM is a legal document that identifies the roads and trails where motor vehicles are allowed.

It is the user’s responsibility to be familiar with the current MVUM.
Printed copies of MVUMs are provided free of charge at local Forest Service offices and on the internet at:
