Tracked ATVs in California: What the State Publishes

California addresses tracks obliquely but in two consequential places. First, the snowmobile definition at Vehicle Code section 557 reaches a motor vehicle designed to travel over ice or snow "in whole or in part on skis, belts, or cleats" - belts and cleats being the statute's language for tracks. Section 38012(b)(2) then brings a snowmobile "or other vehicle designed to travel over snow or ice, as defined in Section 557" into the off-highway identification system, so a tracked machine used over snow is contemplated by the scheme rather than left outside it. Second, and pointing the other way, California's narrow definition of "all-terrain vehicle" at Vehicle Code section 111(a) requires the vehicle to be "Suspended on three or more low-pressure tires" as well as 50 inches or less wide, 900 pounds or less unladen, and steered by handlebars. A quad on four rubber tracks does not satisfy that tire element, so it is not an "all-terrain vehicle" for purposes of provisions keyed to section 111. That is not fatal to registration, because section 38012(b) is a non-exhaustive list and because paragraph (3) speaks of a vehicle "commonly referred to as" an all-terrain vehicle rather than one meeting the section 111 test. What it means for rules that are keyed to the section 111 definition, rather than to the off-highway identification scheme, was not determined.

California does not register off-highway machines as highway vehicles; it identifies them. A motor vehicle of the kind described in Vehicle Code section 38012(b) that is not registered under the code because it is to be used exclusively off the highways must display an identification plate or device issued by the DMV. Per the DMV, ATVs, trail bikes, racing motorcycles, electric motorcycles, dune buggies and snowmobiles do not require regular vehicle registration but must display an ID plate or placard; green ID plates go to compliant machines, including snowmobiles and all off-highway vehicles manufactured before 2002, while red ID plates go to machines manufactured after 2003 that do not meet CARB emission standards. An OHV ID expires on June 30 of the second calendar year after issue. Applying requires an Application for Title or Registration, proof of ownership, a Verification of Vehicle completed by authorised personnel, the fee, and an in-person DMV visit. Exemptions from the identification requirement at section 38010(b) include implements of husbandry, government-owned vehicles, commercial vehicles over 6,000 pounds unladen, and four-wheeled vehicles operated solely in sanctioned closed-course racing.

Except as otherwise provided in subdivision (b), a motor vehicle specified in subdivision (b) of Section 38012 that is not registered under this code because it is to be operated or used exclusively off the highways, except as provided in this division, shall display an identification plate or device issued by the department.Cal.

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 California; what California publishes is directly above.

With a current DMV off-highway identification, a machine may be ridden where the land manager allows it. California's own dedicated riding grounds are the State Vehicular Recreation Areas, which the OHMVR Division names as Carnegie, Clay Pit, Eastern Kern County Onyx Ranch, Heber Dunes, Hollister Hills, Hungry Valley, Oceano Dunes, Ocotillo Wells and Prairie City. The Division's own description of them lists the machines riders bring - dirt bike, ATV, side-by-side, 4x4, dune buggy - and does not mention tracked machines either way, so SVRA eligibility for a tracked quad is an open question to put to the unit rather than something this page can confirm. Beyond the SVRAs, access is governed by whoever manages the land, and state law backs that up: Vehicle Code section 38301 makes it unlawful to operate a vehicle in violation of special regulations promulgated by the governmental agency with jurisdiction over public lands, and section 38300 makes it unlawful to disobey any sign, signal or traffic control device placed under section 38280. We found nothing in Division 16.5 that restricts trail access by running gear - a full-text search of Chapter 5, the operation chapter, returns no occurrence of tire, track or wheel.

Ride your dirt bike, ATV, side-by-side (ROV/UTV), 4x4, or dune buggy on a wide variety of designated terrain and trails available at nine state vehicular recreation areas (SVRAs).California State Parks, Off-Highway Motor Vehicle Recreation Division home page — source · read 2026-09-26

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 California; what California publishes is directly above.

California has no street-legal ATV registration class, and the DMV is explicit that there is no conversion route: "ATVs do not meet federal standards for on-highway use and cannot be converted," and a machine carrying a red ID plate "cannot be registered for on-highway use." What California has instead are two narrow statutory allowances. Section 38025 lets a machine identified under the off-highway scheme use a two-lane highway only to cross at approximately 90 degrees where a quick and safe crossing may be made, or "only when the roadway is not maintained by snow removal equipment and is closed to motor vehicles that are subject to registration," with designated crossing places required on multi-lane or limited-access highways. Section 38026 then allows a local authority, an agency of the federal government, or the Director of Parks and Recreation to designate a highway or segment as a combined-use route where it connects off-highway trail segments or links a recreation area to services. Designations are capped at three miles unless extended under sections 38026.1 to 38026.3, freeways are excluded, the designating body must first notify the Commissioner of the California Highway Patrol and may not designate a segment the commissioner considers a potential traffic safety hazard, and the designation "shall become effective upon the erection of appropriate signs of a type approved by the Department of Transportation." So road use for a tracked quad in California means finding a posted combined-use segment or an unplowed closed road - not obtaining a road registration for the machine.

In addition to Section 38025 and after complying with subdivision (c) of this section, if a local authority, an agency of the federal government, or the Director of Parks and Recreation finds that a highway, or a portion of a highway, under the jurisdiction of the authority, agency, or the director, as the case may be, is located in a manner that provides a connecting link between off-highway motor vehicle trail segments, between an off-highway motor vehicle recreational use area and necessary service facilities, or between lodging facilities and an off-highway motor vehicle recreational facility and if it is found that the highway is designed and constructed so as to safely permit the use of regular vehicular traffic and also the driving of off-highway motor vehicles on that highway, the local authority, by resolution or ordinance, agency of the federal government, or the Director of Parks and Recreation, as the case may be, may designate that highway, or a portion of a highway, for combined use and shall prescribe rules and regulations therefor. A highway, or portion of a highway, shall not be so designated for a distance of more than three miles, except as provided in Sections 38026.1, 38026.2, and 38026.3. A freeway shall not be designated under this section.Cal. Veh. Code sec. 38026(a) (including the three-mile cap and the freeway exclusion); see also sec. 38025 (highway crossings and unplowed closed roads) and sec. 38026(c)-(d) (CHP notification; effective on posting of signs) — 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 California; what California publishes is directly above.

California's dedicated OHV riding grounds are the nine State Vehicular Recreation Areas operated by the OHMVR Division, and beyond them the great majority of the state's riding is on national forest and BLM land where the unit's travel management decisions and motor vehicle use maps control. Vehicle Code section 38301 makes a violation of the managing agency's special regulations a state offence, which is the mechanism that gives those federal and local designations teeth in California. Division 16.5 also sets conduct rules that apply wherever you ride - no speed greater than is reasonable or prudent (section 38305), and reckless operation with wilful and wanton disregard for safety is unlawful (section 38316), with enhanced penalties where it causes bodily injury (section 38317). We found no statewide statutory vehicle width limit for off-highway use; width limits in California come from individual trail and route designations.
