Okla. Stat. tit. 74, § 2279

The purpose of the Oklahoma Trails System Act is to provide public access to, and enjoyment and appreciation of, the Oklahoma outdoors in order to foster the conservation, development and wise use of the natural and historic resources of the state. It is the intent and purpose of the Oklahoma Trails System Act to encourage hiking, bicycling, horseback riding and other recreational activities and, because trail use by motorized vehicles is incompatible with some other trail uses, it is intended to provide separate trails and facilities for motorized vehicles whenever necessary and feasible.
