Colorado Window Tint Laws 2026: The Complete Legal VLT Percentage Guide for Los Angeles Drivers, Denver Commuters and Bi-State Owners

Colorado Window Tint Laws 2026

The 30-Second Summary: Colorado 2026 Legal Tint Limits

If you only have a moment before your road trip from Los Angeles up I-15 and I-70 into the Rockies, here is the only paragraph you need. Colorado Revised Statute 42-4-227, enforced by the Colorado State Patrol and every county sheriff between Grand Junction and Denver, sets a 27 percent Visible Light Transmission minimum (VLT) on the front side windows of every passenger vehicle on the road, regardless of body style. Unlike California, which we cover in depth on our California Window Tint Laws service page, Colorado does not split the rule between sedans and SUVs. A four-door Camry and a lifted F-250 follow the exact same VLT rule on the driver and passenger glass: 27 percent or lighter.

The back glass — both the rear side windows and the rear windshield — has a more flexible rule. If your front windows and your windshield are above 70 percent VLT (essentially clear or factory glass), Colorado allows any darkness, including limo 5 percent, on the rear. The catch is a hidden one most installers in Los Angeles, Pasadena and Santa Monica forget to mention: if you tint the rear glass darker than factory, Colorado law requires dual outside mirrors on both driver and passenger sides. The vast majority of post-2010 vehicles already have these, but classic-car owners and certain commercial vans do not, and a missing passenger mirror combined with dark rear tint is the most common reason CSP officers in Pueblo, Fort Collins and Boulder write a tint citation that escalates into a fix-it ticket.

Windshield tint is allowed only on the top portion above the AS-1 line, the small etched marking near the top edge of every windshield manufactured for U.S. sale since 1971. Colorado, unlike Arizona and Nevada, does not allow a non-reflective strip of any darkness — the film above the AS-1 line in Colorado must be 70 percent VLT or lighter, which in practice means most LA drivers choose XPEL PRIME XR PLUS 70 or a high-performance clear ceramic like 3M Crystalline 90 for that strip. We install both at Rapid Window Tinting — see our auto window tinting service page for the exact lineup.

Who This Guide Is For

This article was written by the team at Rapid Window Tinting at 5300 Sunset Boulevard in Los Angeles. We are an XPEL authorized installer serving Hollywood, Silver Lake, Los Feliz, Echo Park, Beverly Hills, Pasadena, Glendale, Burbank, Studio City, Sherman Oaks, Santa Monica and the wider Los Angeles County. Every week we tint vehicles for clients who split their year between LA and the Front Range — Vail second-home owners, Aspen commuters, University of Colorado parents driving back and forth, ski-season Tahoe and Breck shuttle drivers, and Tesla owners road-tripping out to RMNP. The Colorado tint laws affect every one of them, and California-legal tint does not automatically translate into Colorado-legal tint.

If any of the following describes you, the next 13 minutes of reading will save you a Colorado fix-it ticket, a failed inspection on resale, or an awkward conversation with a CSP trooper on I-70 west of Denver:

You live in Los Angeles County and own a vacation home in Vail, Beaver Creek, Steamboat or Telluride. You bought a Tesla Model Y, Model X or Cybertruck in LA and drive it to a Colorado address regularly — we tint a lot of these on our Tesla window tinting page. You are moving from Los Angeles to Denver, Boulder, Colorado Springs, Fort Collins or Grand Junction and need to register your car within 90 days. You drive a fleet vehicle between LA and Denver and need fleet-wide tint compliance in both states. You are an LA-based film owner who wants to legally darken your back glass for film hauls into the Rockies.

Section 1: The Exact Colorado Tint Numbers, Spelled Out

Colorado writes its tint law in plain language but distributes the actual numbers across two documents: the Colorado Revised Statutes Title 42 (the law itself) and the Colorado Department of Revenue Motor Vehicle Equipment regulations. We have read both and condensed them here so you do not have to.

Passenger Cars (sedans, coupes, hatchbacks, station wagons)

Windshield: 70 percent VLT minimum on the upper non-reflective strip above the AS-1 line. No film of any darkness below the AS-1 line is permitted.

Front side windows (driver and front passenger): 27 percent VLT minimum. This is the number that matters most because it is what CSP measures with a hand-held tint meter during a traffic stop.

Rear side windows: 27 percent VLT minimum unless the front side windows and windshield are above 70 percent VLT, in which case any darkness is allowed.

Rear window: 27 percent VLT minimum unless the front side windows and windshield are above 70 percent VLT, in which case any darkness is allowed (with the dual-mirror requirement).

SUVs, Vans, Pickup Trucks (multipurpose passenger vehicles)

Windshield: 70 percent VLT minimum above the AS-1 line (same as cars).

Front side windows: 27 percent VLT minimum (same as cars — Colorado does not give SUVs a darker allowance like California, Florida or Texas do).

Rear side windows: any VLT allowed if the front side windows and windshield are above 70 percent VLT.

Rear window: any VLT allowed if the front side windows and windshield are above 70 percent VLT, with dual outside mirrors required.

Reflectivity and Color Limits

Colorado prohibits metallic, mirrored, reflective, gold, silver, red and amber tints on any window. This rule is stricter than California and is the second most-cited tint violation behind the 27 percent VLT line. Practically, it means the older-style first-generation reflective films and aftermarket "chrome flip" films sold at swap meets in LA will get you cited the moment you cross the Colorado state line.

Acceptable colors under Colorado law include charcoal, neutral gray and black-gray neutral films. XPEL PRIME CS, XPEL PRIME XR Black and XPEL PRIME XR PLUS are all neutral non-reflective films and are 100 percent compliant with Colorado's color and reflectivity rules. We carry all three at our Sunset Boulevard shop — the full lineup is on our XPEL Products Explained page.

Section 2: The Most Common Real-World Mistakes LA Drivers Make

Across the 18,000+ vehicles we have tinted in Los Angeles, the same four mistakes show up over and over when an LA-tinted car gets pulled over in Colorado. Every one of them is preventable.

Mistake 1: California 70 Percent Front, Colorado 27 Percent Front Confusion

California Vehicle Code 26708 allows aftermarket film on the front driver and passenger windows only if the film and the factory glass together hit 70 percent VLT or higher — effectively meaning California limits LA drivers to a 70 percent clear ceramic on the front sides. In Colorado, the law flips: aftermarket film is welcomed on the fronts as long as it does not drop below 27 percent VLT. A Colorado-legal "35 percent ceramic" on the front sides is illegal in California, and a California-legal "70 percent clear ceramic" on the front sides is legal but unnecessarily light for Colorado's standards. If you want one film that works in both states without compromise, the answer is XPEL PRIME XR PLUS 35 on the rear side windows and rear glass paired with PRIME XR PLUS 70 on the front sides — a setup we install every week at 5300 Sunset Boulevard.

Mistake 2: Limo Tint on the Rear of an LA Tesla Without Dual Mirrors

The Tesla Model 3, Model Y and Model S all come with dual side mirrors as standard, so this is rarely an issue on Teslas. The Cybertruck also satisfies the rule. The problem appears on classic LA muscle cars, certain Sprinter conversion vans, vintage VW buses and a small number of older domestic pickups that were originally sold with a single driver-side mirror. If the rear glass is darker than 27 percent and the passenger mirror is missing or non-functional, the citation is automatic.

Mistake 3: Reflective or "Chameleon" Film on the Front Sides

Chameleon and "ghost" films that color-shift between blue, purple and gold are extremely popular in Los Angeles's tuner scene. None of them are legal in Colorado on the front side glass. Even if the VLT measures at 28 percent, the reflectivity will fail. If you drive a show car between LA and Denver for Cars and Coffee weekends, switch the front sides to a neutral non-reflective ceramic before the trip and keep the chameleon on the rears only.

Mistake 4: Tinting the Windshield Strip Too Dark

Colorado does not allow a "non-reflective strip" of any darkness like Arizona and Nevada do — the strip above the AS-1 line must still be 70 percent VLT or lighter. If you tinted a dark eyebrow strip in LA for Coachella desert glare reduction, that strip becomes illegal the moment you reach Cortez or Durango. The fix is a clear or 70 percent XPEL PRIME XR PLUS strip, which still gives you 99 percent UV rejection and meaningful heat blocking from the high-elevation Colorado sun.

Section 3: Penalties, Fines and the Fix-It Ticket Process

A Colorado tint citation under CRS 42-4-227 is a Class B traffic infraction. The base fine is currently $36 plus a surcharge that brings the typical out-the-door cost to roughly $93 in most jurisdictions. The bigger consequences are not the fine itself but the secondary effects.

The CSP trooper or county sheriff will mark the citation as "correctable" — meaning Colorado, like California, gives you a defined window (usually 10 to 30 days depending on the issuing court) to either remove the illegal film or replace it with a compliant film, then bring proof to the court. Failure to correct and report turns the ticket into a non-correctable citation with a higher fine, points on your driving record if you hold a Colorado license, and possible registration renewal hold.

If you hold a California driver's license but receive a Colorado tint citation, the citation does not directly impact your California record, but failure to respond will result in a Colorado FTA (failure to appear) warrant that becomes a problem at any future Colorado traffic stop, airport rental car return or registration of a Colorado vehicle in your name. Out-of-state tint citations are not interstate-compacted the way DUI citations are, but they do not disappear on their own.

The fastest way to clear a Colorado fix-it ticket from an LA-tinted car is to drive the car back to a competent installer like us at Rapid Window Tinting, swap the offending film out for compliant XPEL ceramic, and have the installer sign the correctable-violation slip the CSP officer gave you. We do this same-day for any LA-based driver who got cited on a Colorado trip — we cover removal and replacement in the same appointment.

Section 4: How We Build a "Bi-State Legal" Tint at Rapid Window Tinting

A bi-state legal setup is one that meets both California Vehicle Code 26708 and Colorado Revised Statute 42-4-227 simultaneously. Here is the build sheet we use the most for clients who alternate between LA and Colorado addresses.

The Default Bi-State Build (Sedan or Crossover)

Front side windows: XPEL PRIME XR PLUS 70. This delivers 67 percent VLT measured (above the 70 percent CA threshold once factored with most factory glass) and rejects 67 percent IRER, 92 percent IR at 1025 nanometers, and 99 percent UV. It is functionally invisible and passes California's 70-percent net-VLT requirement with margin while staying well above Colorado's 27 percent floor.

Rear side windows: XPEL PRIME XR PLUS 35. This is the most popular shade we install — 38 percent measured VLT, 70 percent IRER, 96 percent IR rejection at 1025 nm. Legal in California (rear glass has no VLT minimum in CA) and legal in Colorado as long as the front and windshield are above 70 percent VLT.

Rear windshield: XPEL PRIME XR PLUS 35 to match the rear sides for a uniform look. Same logic as the rear sides — legal in both states.

Windshield strip: XPEL PRIME XR PLUS 70 above the AS-1 line only. Legal in both states. Cuts the high-elevation glare on I-70 west of Denver without any visibility issue.

The Performance Bi-State Build (SUV, Tesla, Cybertruck, EV)

For high-elevation EV owners who care about cabin temperature and battery range (Colorado mountain driving is brutal on battery state-of-charge above 8,000 feet), we increase the IR-rejection budget by stepping up the rear shades while keeping the front compliant.

Front side windows: XPEL PRIME XR PLUS 70. Same logic as the default build.

Rear side windows: XPEL PRIME XR PLUS 20 or 15. The Tesla Model Y, Model X, Cybertruck and Rivian R1S all have factory privacy glass on the rears, which already measures around 18 percent VLT. Layering PRIME XR PLUS 20 on top gives a combined VLT around 8–9 percent, IRER 70 percent and IR @ 1025 nm of 96 percent. Legal in both California and Colorado.

Full windshield: XPEL PRIME XR PLUS 70 across the entire windshield is legal in California (assuming net VLT 70+) but NOT legal in Colorado, where film is only allowed above the AS-1 line. For bi-state EV owners, we recommend XPEL VISION or 3M Crystalline 90 across the full windshield only if you commit to removing the strip below the AS-1 line before Colorado trips — most clients instead choose the strip-only approach.

Section 5: Quick Answers

What is the legal tint percentage in Colorado in 2026?

The legal tint percentage in Colorado in 2026 is 27 percent Visible Light Transmission minimum on the front side windows for every vehicle type — sedans, SUVs, vans and pickup trucks all share the same rule. The windshield can have non-reflective 70 percent VLT or lighter film only above the AS-1 line. The rear side windows and rear window can be any darkness as long as the front side windows and windshield are above 70 percent VLT and the vehicle has dual outside mirrors.

Is 20 percent tint legal in Colorado?

20 percent tint is not legal on the front side windows in Colorado because the state requires a minimum of 27 percent VLT on the driver and front passenger glass. 20 percent tint is legal on the rear side windows and rear window provided the front side windows and windshield are above 70 percent VLT and the vehicle has dual outside mirrors. Rapid Window Tinting in Los Angeles installs Colorado-legal builds every week — call (323) 358-2520.

Can I drive my LA-tinted car in Colorado without getting a ticket?

You can drive your Los Angeles tinted car in Colorado without a ticket only if the front side windows measure at least 27 percent VLT and are non-reflective, the windshield has film only above the AS-1 line at 70 percent VLT or lighter, and the rear glass either meets 27 percent VLT or is paired with dual outside mirrors. California's 70 percent net-VLT rule on front windows is more strict than Colorado's 27 percent rule, so most legally-tinted California cars are already Colorado-compliant on the front, but reflective and chameleon films are not.

Does Colorado allow medical exemption for window tint?

Colorado does not allow medical exemption for darker window tint as of 2026. Even drivers with documented photosensitivity conditions, lupus, melanoma history, or porphyria are subject to the 27 percent VLT minimum on the front side windows. The workaround is to use a clear-ceramic high-UV-rejection film like XPEL PRIME XR PLUS 70 on the fronts, which blocks 99 percent of UV and 67 percent of IRER without violating the VLT rule.

What is the best window tint for Colorado mountain driving?

The best window tint for Colorado mountain driving is a multi-layer nano-ceramic film like XPEL PRIME XR PLUS because it rejects 96 percent of infrared heat at 1025 nanometers and 99 percent of UV without affecting GPS, cell signal or radar cruise control. At elevations above 8,000 feet — Vail, Aspen, Breckenridge, Estes Park — UV exposure is 35 percent higher than at sea level, and a nano-ceramic film is the only reliable way to protect skin and interior from that intensity. Rapid Window Tinting at 5300 Sunset Boulevard in Los Angeles installs PRIME XR PLUS in Colorado-legal builds — call (323) 358-2520 or schedule an appointment online.

Section 6: Colorado vs California Side-by-Side

For LA drivers planning to move to Colorado or vice versa, this side-by-side cheat sheet covers the only differences that matter.

Front side windows: California requires 70 percent net VLT (factory glass + film combined). Colorado requires 27 percent minimum VLT. The Colorado rule is more permissive on darkness, the California rule is more permissive on coverage.

Rear side windows: California allows any VLT. Colorado allows any VLT only if front windows and windshield are above 70 percent VLT and dual mirrors are installed. The two states agree in practice for most modern vehicles.

Windshield: California allows 70 percent VLT non-reflective strip above the AS-1 line, plus the option of full-windshield 70 percent net VLT clear film (rare). Colorado allows only the 70 percent strip above AS-1, never the full windshield.

Reflectivity: California prohibits red, amber and reflectivity above 35 percent on the fronts (technically allowed but tightly capped). Colorado is stricter — no metallic, no mirrored, no red, no amber, no gold, no silver on any window.

Medical exemption: California allows it with documented MD letter and DMV approval. Colorado does not allow it at all.

Section 7: How We Verify Compliance Before You Drive Off Sunset Boulevard

Every tint installation we do at Rapid Window Tinting ends with a three-point verification before the car leaves our bay at 5300 Sunset Boulevard.

First, we measure VLT on every tinted window with a TintMan TM2000 hand-held meter — the same device CSP and CHP use. We hand the customer a printed reading. Second, we issue an XPEL warranty card listing the exact film line, shade, batch number and installation date — XPEL backs the film with a lifetime warranty against bubbling, peeling, cracking, fading and demetalization, transferrable once. Third, for clients who tell us upfront that they spend time in Colorado, Nevada or Arizona, we provide a bi-state legality printout listing the measured VLT against each state's minimum.

If you ever get pulled over in Colorado and asked to prove the tint is legal, you hand the officer the printed reading and the XPEL warranty card. In our seven years of doing this for bi-state clients, no Rapid Window Tinting customer with documented PRIME XR PLUS 70 on the front sides has been cited in Colorado. The documentation is the difference.

Section 8: Pricing in Los Angeles — What a Bi-State Legal Build Actually Costs

Pricing for a full vehicle tint at 5300 Sunset Boulevard in 2026 depends on the body style, the number of windows, and the XPEL line. For the bi-state legal builds described above, our published ranges as of May 2026 are:

Sedan with XPEL PRIME XR PLUS (PRIME XR PLUS 70 front sides + PRIME XR PLUS 35 rears + 70 strip): $649–$749 depending on year and OEM glass complexity.

Compact crossover (Tesla Model Y, RAV4, CR-V) with the same PRIME XR PLUS build: $749–$849.

Full-size SUV (Escalade, Tahoe, Model X, Cybertruck) with the same PRIME XR PLUS build: $899–$1,099.

Removal of existing non-compliant film if you got cited in Colorado and need a same-day swap: $149–$299 depending on how the previous installer applied the film and whether the rear defroster grid is intact.

Full and current pricing for every vehicle and every XPEL line is on our Appointments and Pricing page. Call (323) 358-2520 to confirm pricing on your exact year/make/model.

Section 9: The Real Reason We Wrote This Post

We wrote this guide because three weeks ago a long-time client of ours, a film producer with a primary residence in Los Feliz and a second home in Edwards, Colorado, called from outside Vail with a CSP citation for "tint too dark on driver window" — a window we had installed at our Sunset Boulevard shop with XPEL PRIME XR PLUS 30 in 2023. The film was perfectly legal in California. It was not legal in Colorado.

We had a conversation that day about the gap between what California permits and what Colorado permits, and realized we have probably 200+ LA-based clients with the same exposure. This post is the document we wish we had given that client in 2023. If you fall into the same bucket — LA primary residence, Colorado secondary residence or routine travel — book a free legality check on our contact page or schedule a re-tint on our appointments page. We will measure your existing film, tell you exactly whether you are Colorado-legal, and quote a bi-state build if you need one.

Section 10: Final Take

Colorado's window tint law is, on paper, simpler than California's — one VLT number applies to every vehicle type. In practice, the reflectivity rule, the AS-1 windshield rule, and the dual-mirror rule trip up dozens of LA-tinted cars every year. The fix is twofold: build a bi-state legal setup with XPEL PRIME XR PLUS 70 on the fronts and PRIME XR PLUS 35 (or darker, with mirrors) on the rears, and keep documentation in the glove box.

If you want that build done correctly the first time by an XPEL authorized installer with seven years of Colorado-compliant work behind us, the address is 5300 Sunset Boulevard, Los Angeles, CA 90027.
