In addition to registering a snowmobile with the Secretary of State, a person (resident and nonresident) that operates a snowmobile in Michigan is required to purchase a snowmobile trail permit. The trail permit enables snowmobilers to ride state-designated trails and public roads and public lands (where authorized). It is valid for one year, which begins Oct. 1 and ends Sept. 30 of the following year. State-designated trails are open Dec. 1-March 31 and grooming occurs when there is enough snow on the ground.
Michigan’s snowmobile program is 100% funded by trail permit and registration dollars – dollars that are directly reinvested into the program for the benefit of snowmobilers. The funds pay for grooming, signage, maintenance, bridge and culvert construction, purchase of new equipment, liability insurance; maintenance of trailhead amenities (signage, bathrooms, plowing of parking lots) and other snowmobile-related expenditures.
