ORV Land Use Definitions

The DNR administers over four million acres of land used for a variety of purposes. Wise use of those lands includes preserving natural features and wildlife habitat and encouraging a variety of recreational uses. Just as other users are limited in their activities in order to protect and conserve these vital resources while minimizing conflicts with other activities, ORV enthusiasts are restricted in where and how they may operate.

See state road, trail, and route signs.
