Tracked ATVs in Wyoming: What the State Publishes

Wyoming's statutes use track language, but not in a way that resolves a quad conversion. On the favourable side, the snowmobile definition at W.S. 31-2-401(a)(ii) captures a machine propelled by "any endless belt tread" without requiring skis or runners, phrasing it as runners, OR skis, OR belt tread, OR any combination — though it still requires the machine be "designed primarily for operation over snow," which is the clause a converted quad is most likely to fail. Wyoming also carves "Mobile track-laying units" out of snowmobile registration at W.S. 31-2-408(a)(i), which is expressly a tracked-machine term. On the other side, every branch of the ORV definition is written around tires or wheels: subparagraph (K)(I) measures the 50-inch width limit "from the outside of one (1) tire rim to the outside of the opposite tire rim" and separately caps unladen weight at "one thousand one hundred (1,100) pounds or less"; (K)(II) covers a two-tire motorcycle; and (K)(III) covers a "multi-wheeled motorized vehicle" of more than 900 pounds unladen. Neither the statutes nor the State Parks ORV requirements and FAQ pages say how a quad on four tracks is classified.

"Snowmobile" means any mechanically driven vehicle of a type which utilizes sled type runners, or skis, or any endless belt tread or combination of these, designed primarily for operation over snow.W.S. 31-2-401(a)(ii); ORV definition at W.S. 31-1-101(a)(xv)(K), including the 1,100-pound unladen weight cap in (K)(I); track-laying exemption at W.S. 31-2-408(a)(i) — source · read 2026-09-26

Two separate, modest annual fees depending on the identity. Resident snowmobile registration is $50 annually for private use ($150 commercial, $25 antique), and snowmobiles are exempt from all ad valorem taxes. Nonresidents pay a $75 annual snowmobile user fee. On the ORV side, the owner of an ORV that will be operated on Wyoming ORV trails pays a $15 annual user registration fee, and State Parks confirms that every ORV must display a current Wyoming ORV sticker. State Parks also states the alternative plainly: "You will need either the $15 state ORV permit or the ORV must be licensed and street legal." Both decals are sold online and in person.

The owner of an off-road recreational vehicle which will be operated on Wyoming off-road recreational vehicle trails shall, upon filing of an application, pay to the registration selling agent an annual user registration fee of fifteen dollars ($15.00).W.S. 31-2-703(a) (ORV user registration fee); snowmobile fees at W.S. 31-2-404(a) and nonresident user fee at W.S. 31-2-409(a); the "$15 permit or licensed and street legal" sentence is from the Wyoming State Parks ORV FAQs page — source · read 2026-09-26

Registering a Tracked Quad sets several named agencies' own class definitions side by side, and shows that they are not written to a common test. It settles nothing for Wyoming; what Wyoming publishes is directly above.

Wyoming maintains two large designated systems — State Parks reports over 640 miles of ORV trails and 2,585 miles of snowmobile trails, managed by a variety of agencies — and the machine would be eligible for whichever one matches its registration, if it can get one. A "Wyoming off-road recreational vehicle trail" is a trail, route, road or area specifically designated, marked or signed as such by the Department of State Parks and Cultural Resources, and the $15 permit is what admits you to it. Two practical catches on the ORV side: the width limit, since State Parks states ORVs on trails are not to exceed 50 inches — measure your own machine across the tracks — and the statutory 1,100-pound unladen weight cap in the ORV definition itself. Whether a tracked machine registered on one side may use the other system's trails is unaddressed.

Groomed Snowmobile Trails quotes named agencies in other jurisdictions on the groomed-trail question, and they do not agree with each other. It settles nothing for Wyoming; what Wyoming publishes is directly above.

If the machine qualifies as an ORV, this is where Wyoming is broad — and that "if" is doing real work, because the ORV definition is written around tires and wheels. Assuming ORV status: an ORV may be operated upon any public road rights-of-way, streets, roads or highways in Wyoming, and "public road right-of-way" is defined broadly to include the traveled portions, banks, ditches, shoulders and medians. The main-traveled lanes are the limited part: those require a segment designated open by the agency with jurisdiction AND designated a Wyoming ORV trail by State Parks, and on those segments you need the user registration fee plus proof of liability insurance of at least $25,000 (and the machine is expressly not deemed a motorcycle). Crossings are made at right angles, yielding. A driver's license or permit is required, and State Parks adds that an M or MR endorsement applies for designated roads and routes. Interstate roadways and rights-of-way are closed except under department rules and a barrier-separated designated trail. Under the snowmobile rules instead, operation is allowed within the right-of-way but not the main roadway, at right-angle crossings, on city and town highways by ordinance, on a county roadway if the county commissioners allow it, and on the main-traveled roadway whenever the highway is closed to wheeled vehicular traffic.

An off-road recreational vehicle may be operated upon any public road rights-of-way, streets, roads or highways within Wyoming subject to the following conditions ... As used in this section, "public road right-of-way" means the entire right-of-way of a street, road or highway within Wyoming, including the traveled portions, banks, ditches, shoulders and medians of a street, road or highway except as provided in subsection (e) of this section.W.S. 31-5-1601(a), (c); snowmobile road rules at W.S. 31-5-801(a) — source · read 2026-09-26

Roads, Shoulders and Crossings separates crossing a road from travelling along one in several named jurisdictions, because most of them do. It settles nothing for Wyoming; what Wyoming publishes is directly above.

Wyoming adds two equipment requirements that bite specifically when you leave the pavement for state or federal ground: an approved spark arrester, and a muffler holding propulsion noise to no more than 102 decibels at 20 inches in a stationary test. Beyond that, route designation on Forest Service and BLM land is the land manager's call through its travel plan and motor vehicle use map, and State Parks notes Wyoming's trail mileage is managed by a variety of agencies. ORVs are restricted to established roads and trails rather than open cross-country travel: State Parks answers its own question about why an off-road vehicle cannot simply be driven off the road by explaining that vehicles are typically restricted to established roads and trails.

If operated on state or federal lands, the off-road recreational vehicle shall be equipped with: (A) An approved spark arrester; (B) A noise muffler which produces a propulsion noise level of not more than one hundred two (102) decibels at twenty (20) inches in a stationary test.W.S. 31-5-1601(a)(v) — source · read 2026-09-26
