Registering a Tracked Quad

Two questions, kept apart

Owners tend to ask this as one question — do I need to do anything about registration if I put tracks on it — and every jurisdiction read here answers it as two. The first is what class the machine is in. The second is what registration, permit or trail pass that class requires. Tracks bear on the first question in four of the six places read, and on the second in none of them.

That separation is the reason the answers look contradictory when they are quoted side by side. Michigan and Wisconsin publish a class rule that keeps a converted quad out of the snowmobile class. Maine publishes a trail permission that depends on a converted quad being inside it. Alaska publishes a class rule about a road-use category that neither of the others has. They are answers to different questions about the same machine.

This is a summary of published text. It is not legal advice, the agency is the authority on its own rules, and the rules change. Where this page and an agency page differ, the agency page is right.

The six jurisdictions read

Minnesota: the statute names the conversion

Minnesota is the only jurisdiction read here where the legislature, rather than the agency, addresses an aftermarket track kit by description. The snowmobile definition carries the exclusion in its second sentence.

"Snowmobile" means a self-propelled vehicle originally manufactured and designed for travel on snow or ice steered by skis or runners. Snowmobile does not include the following vehicles equipped with aftermarket ski and track configurations: (1) an all-terrain vehicle defined in section 84.92; (2) an off-highway motorcycle defined in section 84.787; (3) an off-road vehicle defined in section 84.797; (4) a mini truck defined in section 169.011; (5) a utility task vehicle described in section 169.045; or (6) any other vehicle being operated off road.Minnesota Statutes § 84.81, subd. 3, read at the Office of the Revisor of Statutes, 2026-09-26

The cross-referenced all-terrain vehicle definition is written in terms of tires rather than tracks.

"All-terrain vehicle" or "vehicle" means a motorized vehicle with: (1) not less than three, but not more than six low pressure or non-pneumatic tires; (2) a total dry weight of 2,000 pounds or less; and (3) a total width from outside of tire rim to outside of tire rim that is 65 inches or less.Minnesota Statutes § 84.92, subd. 8(a), read at the Office of the Revisor of Statutes, 2026-09-26

Read together, these two say what the machine is not rather than what it is. The snowmobile definition excludes an all-terrain vehicle carrying aftermarket skis and tracks; the all-terrain vehicle definition it points back to is measured at the tire rim. Neither section states which class a quad sits in once the wheels are off it, so in Minnesota the useful question to put to the DNR is a narrow one: does the machine keep its ATV registration with tracks fitted, given that the class is defined at the tire rim.

The DNR states the registration requirement for the class in one sentence.

OHVs used in Minnesota must be registered with the DNR or the operator must possess a trail pass if operating on state and grant-in-aid trails.Minnesota DNR, Off-highway vehicle registrations & fees, read 2026-09-26

The DNR’s current off-highway vehicle regulation summary, published for the 2026–2027 season, was also read. It sets out youth operation, safety certification, road crossings and hunting use, and says nothing about tracks. The DNR describes that summary as a synopsis and refers readers to the statutes for the complete rules.

Michigan: origin of manufacture, on the agency page only

Michigan’s two statutory definitions overlap for a tracked quad, and the tie is broken on a DNR page rather than in either definition. Start with the off-road vehicle class, which expressly contemplates multitrack machines.

"ORV" or, unless the context implies a different meaning, "vehicle" means a motor-driven off-road recreation vehicle capable of cross-country travel without benefit of a road or trail, on or immediately over land, snow, ice, marsh, swampland, or other natural terrain. A multitrack or multiwheel drive vehicle, a motorcycle or related 2-wheel vehicle, a vehicle with 3 or more wheels, an amphibious machine, a ground effect air cushion vehicle, or other means of transportation may be an ORV. An ATV is an ORV.MCL 324.81101(u), read at the Michigan Legislature, 2026-09-26

The same definition then lists what the class excludes, and the first item on that list is “a registered snowmobile.” So the question of which class a tracked quad is in turns on the snowmobile definition, which is in a different part of the same act.

"Snowmobile" means any motor-driven vehicle that is designed for travel primarily on snow or ice and that utilizes sled-type runners or skis, an endless belt tread, or any combination of these or other similar means of contact with the surface upon which it is operated, but is not a vehicle that must be registered under the Michigan vehicle code, 1949 PA 300, MCL 257.1 to 257.923.MCL 324.82101(x), read at the Michigan Legislature, 2026-09-26

A quad with an endless belt tread meets part of that description and not the “designed for travel primarily on snow or ice” part. The DNR resolves it, and it resolves it on a frequently-asked-questions page rather than in either definition above.

Please note: If a motorized vehicle is originally manufactured as an ORV, it's considered an ORV (despite any modifications, including tracks and skis) and it is prohibited from riding designated snowmobile trails.Michigan DNR, ORV FAQs, read 2026-09-26

The test the DNR publishes is origin of manufacture, and it is worth knowing where that test lives: on the agency’s own page, not in either statutory definition above. The agency also enforces its own trail designations, so on the practical question — whether you can take a tracked quad onto a designated snowmobile trail in Michigan — the FAQ above is the published answer, and it is no.

On the permit side, Michigan publishes a two-part structure — a licence for some places and an additional trail permit for others.

Your $26.25 ORV license is required to ride eligible county roads, frozen surface of public waters, state forest roads (open to ORV use) and eligible national forest roads.Michigan DNR, Purchase permit, learn requirements, read 2026-09-26

The ORV license and the ORV trail permit are both valid for one year, which begins April 1 and ends March 31 of the following year.Michigan DNR, Purchase permit, learn requirements, read 2026-09-26

The same page publishes a separate trail permit required in addition to the licence for state-designated ORV trails and scramble areas, and a table of requirements by vehicle type. No row of that table turns on tracks. Treat the fee as the figure most likely to have moved since it was read, and confirm it with the DNR before you budget on it.

Wisconsin: the clearest sentence, in the least obvious place

Wisconsin publishes the most direct statement on a converted quad that was found anywhere in this reading, and it sits under a heading about vehicles that are not snowmobiles on the DNR’s snowmobile registration page.

A vehicle that has inflatable tires is not considered a snowmobile even if skis are attached. An ATV or similar machine that is converted with an aftermarket kit, complete with skis and a track cannot be registered as a snowmobile and cannot be driven on public snowmobile trails.Wisconsin DNR, Snowmobile registration and general information, read 2026-09-26

The class it is being excluded from is defined on the same page, and the definition turns on what the machine was built for. The sentence below is reproduced exactly as the DNR wrote it, including the grammatical slip in the middle of it.

Wisconsin law ss 340.01(58a) defines a snowmobile is an engine-driven vehicle that is manufactured solely for snowmobiling that has an endless belt tread and sled-type runners, or skis, to be used in contact with snow. All snowmobiles must be 48 inches wide or less.Wisconsin DNR, Snowmobile registration and general information, read 2026-09-26

On the other side, the DNR’s all-terrain vehicle registration page defines that class around the manufacturer’s original design rather than the machine’s present condition.

"All-terrain vehicle" means a commercially designed and manufactured motor-driven device which has a net weight of 900 pounds or less, was originally manufactured with a width of 50 inches or less, equipped with a seat designed to be straddled by the operator and which is designed by the manufacturer to travel on three or more low-pressure or non-pneumatic tires.Wisconsin DNR, ATV and UTV registration, read 2026-09-26

The same page states that only machines meeting the statutory definitions can be registered and used on public trails, and that vehicles which cannot be registered as an ATV or UTV may be operated on private land only, with the landowner’s consent. Neither Wisconsin page says whether fitting a track kit affects a machine’s existing ATV registration — the snowmobile page answers the snowmobile question and stops — so that is the one to ask the DNR before the season starts rather than at a trailhead.

Maine: an exception whose condition is not explained

Maine is the jurisdiction here where the two pages read point in different directions, and the department publishes both without reconciling them. The ATV class expressly includes multitrack machines.

"All-terrain vehicle" or "ATV" means a motor-driven, off-road, recreational vehicle capable of cross-country travel on land, snow, ice, marsh, swampland or other natural terrain. "All-terrain vehicle" or "ATV" includes, but is not limited to, a multitrack, multiwheel or low-pressure tire vehicle; a motorcycle or related 2-wheel, 3-wheel or belt-driven vehicle; an amphibious machine; or other means of transportation deriving motive power from a source other than muscle or wind.Maine Department of Inland Fisheries and Wildlife, Laws & Rules: All-Terrain Vehicles, Title 12 §13001, read 2026-09-26

That definition then excludes a snowmobile, and the snowmobile definition on the department’s other page turns on original design.

"Snowmobile" means a vehicle propelled by mechanical power that is primarily designed to travel over ice or snow and is supported in part by skis, belts, or cleats.Maine Department of Inland Fisheries and Wildlife, Laws & Rules: Snowmobiles, Title 12 §13001, read 2026-09-26

Both pages nonetheless carry an exception to the snowmobile-trail prohibition that presupposes a tracked quad can hold a snowmobile registration.

Exception: An ATV with tracks, registered as a snowmobile, may be operated on snowmobile trails.Maine Department of Inland Fisheries and Wildlife, Laws & Rules: All-Terrain Vehicles, read 2026-09-26

Neither page read sets out how a machine that was not primarily designed to travel over ice or snow is registered as a snowmobile in Maine. The exception says what a tracked ATV registered as a snowmobile may do; it does not say how that registration is obtained. So do not buy a kit for Maine trail riding on the strength of that sentence — put the question to IFW in writing first and keep the answer.

Maine also states its baseline registration requirement plainly, which is the part no owner should read past.

Except as provided in paragraph A and subsection 5-B, a person may not operate an ATV that is not registered in accordance with subsection 3.Maine Department of Inland Fisheries and Wildlife, Laws & Rules: All-Terrain Vehicles, Title 12 §13155, subd. 1-A, read 2026-09-26

Alaska: the only road-use class that names tracks

Alaska is the one jurisdiction read here where fitting tracks bears on a road-use registration class rather than on a trail class. The DMV distinguishes off-highway vehicles, which are registered for off-road use, from all-purpose vehicles, which may be operated on some public roads.

Beginning January 1, 2022, you must title and register your APV if you intend to operate it on a public road or highway in a community that has not prohibited its use.Alaska DMV, Off-Highway & All-Purpose Vehicles, read 2026-09-26

The page then lists the vehicle types the division has determined cannot hold that registration. Two entries on the list bear directly on a quad with tracks on it, and the second uses the word “adapted.”

The following vehicle types cannot be registered as APVs: Off-highway vehicles 13 AAC 40.010(a)(30); Snowmachines or snowmobiles (vehicles steered with skis or driven by tracks/belts); Tracked vehicles; Homemade or individually constructed ATVs (e.g., moose/tundra buggies); Hovercraft; Two-wheeled recreational vehicles (e.g., dirt bikes, off-road motorcycles); Three-wheeled recreational vehicles (e.g., 3-wheelers, trikes); Any vehicle designed or adapted primarily for cross-country travel over unimproved terrain.Alaska DMV, Off-Highway & All-Purpose Vehicles, read 2026-09-26 (list reproduced as a single run, bullet markers removed)

What the page does not publish is whether a wheeled quad fitted with an aftermarket track kit counts as a tracked vehicle for the purposes of that list, or what happens to an APV title and registration already issued to a machine that is later converted. If you hold an APV registration and ride on public roads in Alaska, that is the question to settle with the division before the kit goes on rather than after.

The DMV does publish that the two classes are convertible in one direction: an owner may surrender an APV title and registration, after which the vehicle can be issued off-highway vehicle registration. Off-highway registration itself runs in multi-year terms from the date of initial registration, and the page sets out what a dealer and a private buyer each have to present.

Ontario: a registration regime that does not mention tracks

Ontario registers off-road vehicles centrally and plates them, which is a different structure from the decal-and-trail-pass model used by the five American jurisdictions above.

Off-road vehicles must be registered with the Ministry of Transportation at a ServiceOntario centre. This applies to both new and used vehicles. You must be 16 years or older to register an off-road vehicle, and you must be able to prove you own the vehicle.Ontario Ministry of Transportation, Official MTO Driver’s Handbook: Off-road vehicles and snowmobiles, page updated 2026-07-24, read 2026-09-26

If you are driving your off-road vehicle anywhere other than on the vehicle owner's property, you must also have vehicle liability insurance. You must carry the insurance card with you and show it if requested by a police officer.Ontario Ministry of Transportation, Official MTO Driver’s Handbook: Off-road vehicles and snowmobiles, page updated 2026-07-24, read 2026-09-26

The class the province registers is defined around wheels, and the handbook leaves the four-wheel case to regulation rather than stating it.

Off-road vehicles (sometimes called ORVs) are any two- or three-wheeled motorized vehicles, as well as specific vehicles with four or more wheels as prescribed by regulation, intended for recreational use.Ontario Ministry of Transportation, Official MTO Driver’s Handbook: Off-road vehicles and snowmobiles, page updated 2026-07-24, read 2026-09-26

The handbook publishes nothing about tracks. It refers readers to the Off-Road Vehicles Act, the Motorized Snow Vehicles Act, and the regulation that prescribes which four-or-more-wheeled vehicles are off-road vehicles — those three instruments, not the handbook, are where a definitive Ontario answer would come from, and none of them was read for this entry.

What this adds up to

Of the fourteen pages read on 2026-09-26, none set out a test by which a wheeled all-terrain vehicle fitted with an aftermarket track kit becomes a snowmobile for registration purposes. Maine is the nearest thing to an exception and it is not one: its exception assumes such a registration exists without publishing how it is obtained.

Of the same fourteen, none stated that fitting tracks ends or invalidates an existing all-terrain-vehicle or off-road-vehicle registration. Alaska’s list of vehicle types ineligible for its on-road all-purpose class is the closest published text on that question, and the DMV page does not say how the list applies to a converted quad.

Four of the six published something that turns on tracks, and the four are not written to the same test. Minnesota’s turns on aftermarket fitment by description, Michigan’s on origin of manufacture, Wisconsin’s on what the machine was manufactured solely for, and Alaska’s on whether a vehicle was designed or adapted primarily for cross-country travel. Those four tests could produce four different answers about the same quad, and nothing read here suggests they are meant to agree.

Two of the six published nothing about tracks on the pages read. That is recorded as an absence of published guidance, not as a permission and not as a prohibition.

If your state is not one of the six

Six is what has been read. For anywhere else, the two questions above are the ones to put to your own agency, and asking them in that order saves a second phone call: what class is my machine in with tracks fitted, and what registration, permit or trail pass does that class need. Ask about the specific machine — make, model, model year — rather than about tracked quads in general, because four of the six tests above turn on how a machine was originally manufactured, which is a fact about your quad and not about the kit.

Three things sit outside this page and are worth chasing separately, because the pages read show they run through different bodies. Title and sales tax: Michigan directs ORV titling to the Secretary of State, and Minnesota takes registration renewals at a deputy registrar of motor vehicles, so neither is answered by the trail agency. Insurance: whether a carrier treats a track kit as a declarable modification is a question for the carrier, in writing, before the kit goes on. And roads, shoulders and crossings, which is the question most often confused with this one and is governed by different sections of the same statutes.

Trail access rather than registration is on groomed snowmobile trails, which reads an overlapping but not identical set of pages.

Your own state’s registration entry

Each of the 50 states has a registration and titling entry of its own, read from what that state publishes and dated. Those pages are linked below, and the fastest version of the two questions above is to open yours and read that one section before you telephone anybody.

There is no answer column here, and its absence is deliberate. Everywhere else on this site a roll-up prints how each state’s entry reads, because the underlying field records a permission. The registration field does not: it is a summary and a citation, with no classification behind it. Sorting 50states into registered, not registered and re-registered would mean making that many judgements by hand and printing them as though they had been read off a page — and whether fitting tracks changes what a machine is registered as is exactly the question most of these codes have never been applied to. The state page is where the answer is, in that state’s own words.

The date beside each state is when that state’s registration entry was read, not when this page was written. Read one of these as a reading of one jurisdiction on that date: nothing in the list was derived from any other row, and nothing in it crosses a state line.
