Tracked ATVs in Michigan: What the State Publishes

Michigan addresses tracks in two places, and both are favourable. The ORV statutory definition itself contemplates tracked machines — MCL 324.81101(u) says a “multitrack or multiwheel drive vehicle… may be an ORV,” adds that “An ATV is an ORV,” and excludes only “a registered snowmobile,” not a tracked one. Separately, the DNR maintains a page titled “Use of modified ORVs and snow bikes” holding that original manufacture controls classification, so a factory quad with tracks fitted is still an ORV and keeps ORV privileges. The DNR's ORV FAQ repeats this and names tracks and skis specifically. The one limit is snowmobile trails; note that the two DNR pages state that limit slightly differently — the modified-ORV page permits dual-purpose trails and bars snowmobile-only, while the FAQ says flatly that such a machine “is prohibited from riding designated snowmobile trails.”

If a motorized vehicle is originally manufactured as an ORV, it's considered an ORV (despite any modifications). Operation is permitted in the following situations: Motorized recreational vehicles must be operated and registered as designed by the manufacturer, despite any modifications. Modified ORVs are permitted to operate on snowmobile and ORV trails designated as dual purpose. Modified ORVs are not allowed on trails that are designated as snowmobile-only.Michigan DNR, “Use of modified ORVs and snow bikes” — source · read 2026-09-26

Nothing changes when you fit tracks: you register and license the machine as manufactured. An ORV license is $26.25 and is required to ride eligible county roads, the frozen surface of public waters, state forest roads open to ORV use, and eligible national forest roads. An ORV trail permit is an additional $10 ($36.25 total) and is required on state-designated ORV trails, routes and scramble areas. Both run April 1 to March 31. Neither is required to operate on private land. Residents also obtain an ORV certificate of title through the Secretary of State when buying, selling or transferring.

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 Michigan; what Michigan publishes is directly above.

Permitted as a class; conditional in practice on trail type and, we think, on width. Classification is not the problem: a modified ORV remains an ORV, state-designated ORV trails, routes and scramble areas are open with an ORV license plus trail permit, and a modified ORV is expressly permitted on trails designated dual purpose for snowmobile and ORV use. Michigan also confirms ORVs may be ridden in winter during snowmobile season, December 1 to March 31, with a request that riders prefer ORV-designated trails or roads not open to snowmobiles so as not to undo grooming. Two limits bite. Snowmobile-only trails are closed. And the DNR's own description of a designated ORV trail is “a path or way capable of travel by a two- to four-wheel vehicle 50 inches wide or less” — a tracked quad is not a two- to four-wheel vehicle, and whether it comes in under 50 inches depends on your kit and your quad, so measure it and confirm the specific trail class with the managing unit rather than assume the whole designated-trail network is usable.

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 Michigan; what Michigan publishes is directly above.

Conditional on local authorisation, the same as for any Michigan ORV. Eligible county roads are open with an ORV license where a county or municipality has adopted an ORV ordinance under MCL 324.81131; state forest roads open to ORV use and eligible national forest roads are also covered by the ORV license. A separate provision requires a driver's license to operate on roads authorised under that section where the ORV is registered as a motor vehicle and is more than 65 inches wide or has three wheels — measure your machine so you know which side of 65 inches it falls on.

Unless the person possesses a license as defined in section 25 of the Michigan vehicle code, 1949 PA 300, MCL 257.25, a person shall not operate an ORV as authorized pursuant to subsection (2), (3), (5), or (6) if the ORV is registered as a motor vehicle under chapter II of the Michigan vehicle code, 1949 PA 300, MCL 257.201 to 257.259, and either is more than 65 inches wide or has 3 wheels.MCL 324.81131(11) — 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 Michigan; what Michigan publishes is directly above.

Broad. Michigan reports over 4,000 miles of riding, a figure that already bundles state-designated ORV trails, scramble areas, eligible county roads, state forest and national forest roads, and frozen surfaces of public waters — it is not 4,000 miles of trail with road mileage on top. The DNR separately states that the majority of state forest roads are now open to ORV use, providing thousands of miles to ride. The frozen surface of public waters is open with an ORV license, which is the permission most relevant to a winter tracked machine, and forest roads are the part of the system least sensitive to a machine's width. ORVs are generally prohibited in state parks and recreation areas, with a handful of ORV-friendly state parks and state forest campgrounds excepted. ORV license and trail permit are not required on land owned or controlled by the owner.
