Travel Management

The Forest Service announced new travel regulations in November 2005, governing motor vehicle use on national forests and grasslands. The new rule requires each National Forest or ranger district to designate those roads, trails, and areas open to motor vehicle use.

Motor Vehicles are defined as any vehicle which is self-propelled, other than a wheelchair or mobility device as defined in 36 CFR 261.2, including highway legal and non-highway legal terra vehicles. This definition excludes aircraft, watercraft, and over snow vehicles according to 36 CFR 212.51

Many roads are described as mixed use, which is a designation of a National Forest System Road which means that the road can be used by both highway-legal and non-highway-legal motor vehicles, as per state law. In the motorized mixed-use analysis, a qualified engineer will consider mitigation of observed safety risks through such measures as signs, speed controls, user education, modifications to road geometry, regulating the timing of commercial hauling, or other safety measures.
