Tracked ATVs in Missouri: What the State Publishes

Missouri does address tracks, but in a way that gives with one hand and not the other. The Chapter 304 definition of 'off-road vehicle' in RSMo 304.001(9) is expressly track-inclusive: it means 'any vehicle designed for or capable of cross-country travel on or immediately over land, water, ice, snow, marsh, swampland, or other natural terrain without benefit of a road or trail,' 'Including, without limitation,' among other things a 'Vehicle using an endless belt, or tread or treads, or a combination of tread and low-pressure tires.' Its exclusions (registered motorboats, aircraft, military, fire and law enforcement vehicles, farm tractors, farm and construction equipment on a work site, mowers and golf carts in their designed use, handicapped-transport vehicles, electric bicycles) do not reach a recreational tracked quad. So read against that definition a tracked machine appears to be an off-road vehicle in Missouri - which is the term the statewide stream-and-river prohibition in RSMo 304.013(2) uses. The permissive term is the other one. RSMo 301.010(1) defines an 'all-terrain vehicle' as any motorized vehicle manufactured and used exclusively for off-highway use, with an unladen dry weight of 1,500 pounds or less, 'traveling on three, four or more nonhighway tires,' with EITHER (a) a straddle seat and handlebars for steering control, OR (b) 'A width of fifty inches or less, measured from outside of tire rim to outside of tire rim, regardless of seating or steering arrangement.' A machine with tracks in place of its tires appears to satisfy neither the tire requirement nor, under prong (b), the rim-to-rim measuring instruction. And it is the ATV term that carries the registration duty (RSMo 301.707) and every highway exception (RSMo 304.013(1)). One trap to avoid on top of all this: Missouri's definition of 'motor vehicle' in RSMo 301.010 reads 'any self-propelled vehicle not operated exclusively upon tracks,' and that phrase means railroad tracks, not rubber track systems. It should not be cited as a rule about track kits. The offices to confirm with are the Missouri Department of Revenue (ATV registration and titling) and the park office at St. Joe or Finger Lakes for riding-area questions.

"Off-road vehicle", any vehicle designed for or capable of cross-country travel on or immediately over land, water, ice, snow, marsh, swampland, or other natural terrain without benefit of a road or trail: (a) Including, without limitation, the following: ... e.

Missouri requires an ATV to be registered for off-road use, and a tracked owner should register rather than assume an exemption - but note what the duty attaches to. RSMo 301.707(1) provides that no person shall operate an ALL-TERRAIN VEHICLE within the state unless it has been registered with the Department of Revenue, with exceptions only for government-owned machines and for ATVs covered by a valid registration of another state or country that have not been within Missouri for more than thirty days; no person under sixteen may register an ATV. Because 'all-terrain vehicle' is defined in RSMo 301.010(1) around nonhighway tires, whether the duty reaches a machine on four tracks is unresolved - and so is whether the Department will issue the registration. On registration the Department issues a decal showing the registration number and expiration date, which must be displayed at all times and affixed to the right front fork or frame of the all-terrain vehicle where it is clearly visible. The fee is ten dollars for a three-year registration, with a five dollar penalty on delinquent registrations and a $7.50 fee for a duplicate certificate or decal. ATVs are also titled - under RSMo 301.700 they are treated the same as motor vehicles for transfer, titling, liens and taxes. The decal's mounting point (the right front fork or frame) survives a conversion.

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 Missouri; what Missouri publishes is directly above.

Missouri State Parks operates two ORV areas with almost 3,000 acres of riding between them - but the published rules are written by machine type and never mention tracks, so a tracked machine's eligibility is a phone call, not a published fact. Finger Lakes State Park states that 'Approved vehicles or equipment in the off-road vehicle (ORV) areas include all-terrain vehicles (ATVs), side-by-sides and motorcycles,' and prices ORV permits at $6 per vehicle per day for ATVs and motorcycles and $10 for UTVs; its terrain is steep hills and deep ravines plus a motocross track designed by professional riders. At St. Joe State Park, trails wind through wooded portions of the park and across acres of sand flats left by lead-mine tailings, and the park's rules add that 'Dune buggies and four-wheel drive vehicles are permitted only in the tailings area, not on the wooded trails.' Missouri State Parks' ORV Riding page notes that at St. Joe 'A trail from the campground to the ORV area provides access to unlicensed ORVs that are not permitted on park roads.' An ORV permit is required (not a general park entrance permit); permits can be bought online for up to three days or at the park, and riders must carry the permit at all times when operating. Equipment required: a DOT or ANSI Z90.1 helmet for operators and passengers, functioning brakes, a spark arrester and a muffler with noise not exceeding 86 dBA, and for ATVs and side-by-sides an orange flag on a flexible 72-inch mast - at least 64 square inches at Finger Lakes, at least 72 square inches at St. Joe.

RSMo 304.013(1) bars ATVs from the highways of this state except in six situations, and two of those are ordinary permits a private owner can actually get: the governing body of a city may issue a special permit to a licensed driver for special uses of an ATV on highways within the city limits, at a fee of fifteen dollars, and the governing body of a county may issue a special permit to a licensed driver for special uses of an ATV on county roads within the county, also at fifteen dollars. In addition, municipalities may by resolution or ordinance allow ATV operation on streets or highways under their jurisdiction, in which case the operator must maintain proof of financial responsibility under RSMo 303.160 or equivalent liability coverage for the ATV. The other exceptions are government-owned machines in official use, agricultural or industrial on-premises purposes between official sunrise and sunset, and handicapped persons for short distances occasionally on secondary roads between sunrise and sunset. Any highway operation under an exception requires a valid operator's or chauffeur's licence, a speed of less than thirty miles per hour, and a bicycle safety flag extending not less than seven feet above the ground attached to the rear, triangular, not less than thirty square inches, day-glow in colour. A fastened safety helmet is required unless the operator is at least eighteen. No passengers except for agricultural purposes, unless the seat is designed to carry more than one person. Violation is a class C misdemeanor, with civil penalties up to $1,000 per day available to the attorney general or county prosecutor.

No person shall operate an all-terrain vehicle, as defined in section 301.010, upon the highways of this state, except as follows: ... (4) Governing bodies of cities may issue special permits to licensed drivers for special uses of all-terrain vehicles on highways within the city limits. Fees of fifteen dollars may be collected and retained by cities for such permits; (5) Governing bodies of counties may issue special permits to licensed drivers for special uses of all-terrain vehicles on county roads within the county. Fees of fifteen dollars may be collected and retained by the counties for such permits;RSMo 304.013(1)(4)-(6), 304.013(3) — 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 Missouri; what Missouri publishes is directly above.

The two state park ORV areas are the designated riding grounds. On Missouri Department of Conservation areas the rule is narrow: 'Vehicle use is restricted to graveled and paved roads and established parking areas, unless otherwise posted,' and 'State laws regarding the operation, registration and required equipment apply to the operation of motor vehicles on locations open to vehicular traffic on department areas' - so conservation areas are access, not riding. Missouri also has a statewide stream and river restriction, and it is the one provision here that appears to catch a tracked machine squarely, because it is written around the track-inclusive 'off-road vehicle' definition in RSMo 304.001(9): no person shall operate an off-road vehicle within any stream or river in the state, except within waterways flowing inside land the operator owns, or for agricultural purposes within land the operator owns or has permission to be upon, or to ford a stream or river at customary road crossings or crossings that are part of the highway system. Conservation agents and DNR park rangers enforce that alongside other peace officers. The text of that restriction is in RSMo 304.013(2) at the Revisor of Statutes, not on the conservation rule page this field links to.
