The main purpose of this legislation, known as the Shawnee TRAILS Act, is to ensure that at least 20 percent of the trails in the Shawnee National Forest are designated and maintained for recreational use by specific types of vehicles. This includes electric bicycles and off-highway vehicles like all-terrain vehicles and off-road vehicles. The act aims to promote outdoor recreation while also considering the management of natural resources. Key provisions of the act require the Secretary of Agriculture to designate these trails specifically for the use of covered vehicles.
