If you have ever wondered “are UTVs street legal in Colorado?” the short reply is “not by default.” At state level Colorado treats a UTV as an off-highway vehicle (OHV). That classification bars it from most public roads, highways, and public streets. However, dozens of counties and small towns—especially in the high country—have passed local ordinances that open selected county roads to street-legal UTVs. When you leave those designated stretches you are back under the statewide ban. Knowing which jurisdiction you are in, and what each rulebook demands, is therefore essential for every rider.

Colorado’s OHV Framework in Plain English
Colorado Parks and Wildlife (CPW) issues every OHV—including your utility terrain vehicle—with an annual OHV registration or non-resident permit. That bright-green sticker is proof you have paid the annual registration fees and carries your registration confirmation receipt. It lets you ride on signed motorised trails across public lands managed by CPW, the Forest Service, and BLM.
Yet registration alone does not make your machine a “legal vehicle” on tarmac. An OHV retains its off-road status even if you add indicators, brake lights, or a windscreen. Only a county or municipality can authorise on-road operation—and they may revoke that privilege whenever they see fit. The state specifically forbids OHVs on interstate highways and most state highways, so even in permissive counties you must trailer the machine until you reach an approved back-road network.
County-by-County Street Legality
Below are the hotspots where local ordinances welcome or tolerate street-legal UTVs. Always double-check an official map before you roll; boundaries shift and deputies will enforce the letter of the law.
| County / Town | Key Open Routes | Notes & Contacts |
|---|---|---|
| San Juan County (Silverton) | Alpine Loop, selected San Juan County Roads, the main street through Silverton | Must carry liability insurance and obey 15 mph town limit. Map at the Sheriff’s Office. |
| Hinsdale County (Lake City) | County Road 20 & connectors | Valid drivers licence required; speed cap 25 mph inside town limits. |
| Ouray County | Yankee Boy Basin road and connectors | Riding allowed only between 8 am – 8 pm; contact 970-325-2211 for updates. |
| San Miguel County (Telluride) | Parts of the Rimrocker Trail and side roads | Helmet or approved eye protection compulsory under 18. |
| Montrose County | Links the Rimrocker Trail west to Utah | Follow posted speed limits (generally 35 mph). |
| Chaffee County (BV & Salida) | Specific county roads around the Arkansas River corridor | Machines must display a slow-moving triangle at night. |
| Canon City (Fremont County) | Pilot scheme on Gravel Gulch loop | Seat-belt use enforced; expect random safety inspections. |
Remember: a friendly sign disappears quickly once you cross into an adjacent county such as Lake, Custer, or Mesa. Your UTV goes from welcome guest to unlawful intruder in the space of a cattle-grid.
Equipment Checklist for Street-Legal Status
Local ordinances share a core kit list. Missing items invite a fine or immediate tow:
- A rear-mounted legal licence plate (or temporary plate) visible from 100 ft
- Front and rear brake lights plus tail-lights
- One or two mirrors—most counties accept either rear-view mirror or side mirrors
- DOT-approved tyres; be prepared for a tread inspection
- A working horn audible at 200 ft
- Seat belts for every occupant if factory-fitted anchor points exist
- Spark arrestor and muffler compliant with CPW noise code
- Approved eye protection for anyone in an open cab
- Proof of liability insurance matching Colorado minimums
- Current OHV sticker or street-legal registration where offered (e.g., South Fork’s pilot scheme)
- Original title or proof of ownership in the glove box for roadside checks
Carry a reflective safety flag on popular trails such as the Alpine Loop; San Juan County lists it as “strongly recommended.”
Registration Options (and Why South Dakota Plates Keep Popping Up)
Colorado’s Department of Revenue does not issue on-road plates to UTVs. Riders wanting nationwide access often form a Montana LLC set-up or register the machine in South Dakota, the easiest US state for street-legal SxS registration. That process yields proper license plates and a motor-vehicle title that many Colorado counties honour on local tarmac—though state patrol officers can still ticket you on highways.
If you keep the machine here year-round you still need the green CPW sticker for trail access. Display both credentials: road plate for the sheriff, OHV sticker for the ranger.
Riding on Public Lands and Signature Trails
Colorado rewards compliant riders with unrivalled scenery:
- Alpine Loop (Lake City to Silverton) mixes historic mining roads with alpine passes above 12 000 ft.
- Rimrocker Trail links Montrose to Moab via 160 miles of high-desert two-track.
- San Juan County Roads thread ghost towns, wildflower meadows, and sheer drop-offs.
While these routes cross public lands, they remain “roads” once signed for OHV use. That means staying in a single lane of traffic, indicating turns, and respecting every posted speed limit. Stray off-trail and both county deputies and federal rangers may cite you for habitat damage.
Traffic Laws You Must Obey on Public Streets
A street-legal UTV becomes a “road vehicle” the moment its tyres touch an authorised tarmac surface. You therefore accept the same traffic laws that bind passenger cars:
- Drive on the right and stop fully at red lights and stop signs.
- Use hand signals or indicators when changing lanes.
- Keep to 35 mph (or lower) on most town streets; some resort towns impose 15 mph.
- Never ride two-abreast; Colorado calls for single-file in a defined lane of traffic.
- Stay off any interstate highways or state highways unless merely crossing at 90 degrees.
High-country sheriffs report that speed and noise complaints are the top reasons they revoke OHV access. A courteous throttle ensures the privilege lasts.
Penalties and the State’s Safety Rationale
Governor Jared Polis signed SB21-067 in 2021, clarifying that OHVs remain “non-highway” unless a local ordinance says otherwise. Colorado State Patrol chief Colonel Matthew Packard praised the measure, noting it “keeps everyone as safe as possible regardless of what they are driving.”
A first-time citation for illegal road use can exceed £200, plus court fees. Repeat offenders may face vehicle impoundment and an appearance before the county judge. Always carry the compliance kit listed earlier; deputies seldom forgive missing safety equipment.
Frequently Asked Questions
Do I need a driving licence to operate a UTV on county roads?
Yes. Every open county requires a valid driver’s licence; many set a minimum age of 16.
Is special insurance required?
You must carry minimum liability insurance equal to Colorado’s passenger-car standard (currently $25 000/$50 000 bodily injury and $15 000 property damage).
Can I ride on Forest Service roads not listed by the county?
Only if those roads appear as “open to motorised vehicles” on the annual motor vehicle usage maps (MVUM). Otherwise stay off.
What about using a UTV for agricultural purposes?
Farmers may operate OHVs on the shoulder of their county roads between fields. They must keep an amber beacon flashing and stay within the posted speed limit.
Will Colorado introduce statewide street-legal registration?
As of May 2025 there is no Bill before the Assembly to create such a programme. Riders seeking broader access still rely on out-of-state plates or county pilot schemes.
Final Thoughts
Colorado’s stance on UTVs is neither a green light nor a blanket ban; it is a mosaic of local ordinances painted over a firm statewide foundation that regards the machines as off-highway vehicles. Stick to the approved county roads, respect every welcome sign, and keep your kit in perfect order. Do that and you will enjoy the unrivalled mix of alpine passes, red-rock mesas, and pine-scented public lands that make the Centennial State a magnet for road enthusiasts the world over. Safe riding!
