Wyoming Window Tint Laws (2026): Legal VLT Limits

Wyoming law requires front side windows to allow at least 28% of visible light through, with the same 28% minimum applying to back side and rear windows on sedans. Multipurpose vehicles (SUVs, pickups, and vans) may use any tint darkness on windows behind the driver, provided dual outside mirrors are in place.

What is the legal tint limit in Wyoming?

Wyoming sets its window tint limits under W.S. 31-5-962. To understand the numbers, keep this rule in mind: higher VLT percentages mean lighter (less dark) tint, and lower VLT percentages mean darker tint. A window rated at 28% VLT blocks 72% of visible light and allows only 28% to pass through. That is a fairly dark film and is among the more permissive front-side standards in the country.

For sedans, the 28% minimum applies to all three window zones: front side windows, back side windows, and the rear window. Wyoming draws a clear distinction for multipurpose vehicles. If your vehicle is an SUV, pickup truck, or van and it has dual outside mirrors, the windows behind the driver's seat are not subject to any darkness limit. You can use any tint level on back side and rear windows in that case. The front side windows on multipurpose vehicles still must meet the 28% minimum.

The dual-mirror requirement for multipurpose vehicles is not optional. Without functioning dual outside mirrors, any-darkness tint on rear windows would not be legal even on an SUV or truck.

Windshield tint rules in Wyoming

Wyoming permits non-reflective tint on the windshield only in the area above the AS-1 line or within the top 5 inches of the glass, whichever is the applicable reference for your vehicle. This is the standard sun-visor strip provision found in most state tint laws. Below that line, in the primary driving vision area, no aftermarket film is permitted.

The non-reflective requirement matters: whatever film goes on the windshield strip must not increase the reflectivity of the glass. Wyoming also caps luminous reflectance on any window at 20%, which rules out mirrored, metallic, or chrome-effect films across all window positions. These films reflect light back toward other drivers and can create dangerous glare conditions, which is why they are regulated separately from VLT.

Wyoming does not list specific banned colors in the primary statute, but the practical effect of the 20% reflectance cap is to exclude the most problematic colors, such as bright silver and chrome films often used to achieve a mirror appearance.

Medical exemptions

Wyoming's primary vehicle statute, W.S. 31-5-962, does not specify a formal medical exemption procedure in the available primary source text. This contrasts with states like Wisconsin, which have explicit provisions allowing darker front-side tint with a physician's written statement.

If you have a medical condition requiring reduced sun exposure, consult with Wyoming's Department of Transportation or your county sheriff's office before relying on a darker front-side tint. Some states without an explicit statutory exemption may have administrative or departmental policies that address medical needs, and a law enforcement agency can clarify what documentation, if any, they would recognize.

Until Wyoming provides clear statutory guidance on medical exemptions, the safe approach is to comply with the 28% front-side standard regardless of medical need. If you have a condition that genuinely requires lower VLT, speak with a local attorney familiar with Wyoming traffic law before proceeding.

How tint is measured and certified

Wyoming law enforcement uses VLT meters to check window tint compliance during roadside stops. The meter measures how much visible light passes through the glass and any applied film combined. The reading is compared to the legal standard for that window position.

Wyoming's statute does not specify a published measurement tolerance in the primary source. In practice, many states operate with an informal tolerance of a few percentage points, but Wyoming drivers and installers should target compliance that clearly meets the 28% front-side standard rather than relying on any assumed margin. Readings at or near the line can vary between different meters and environmental conditions.

Wyoming does not appear to require a mandatory compliance sticker or installer certification label under W.S. 31-5-962. However, keeping the installer's certificate showing the film's VLT rating in the vehicle is a practical safeguard. If a meter reading is close to the limit, the installer's documentation of the film specification can support your position that the tint is compliant when combined with the factory glass.

Penalties for illegal tint in Wyoming

Wyoming's window tint law falls under the state's vehicle equipment statutes at Title 31 of the Wyoming Statutes. While specific penalty dollar amounts are not enumerated in the tint provision itself, window-equipment violations in Wyoming are generally treated as misdemeanor-level traffic offenses that carry fines and may require correction of the equipment violation.

An officer who determines your tint is non-compliant can issue a citation at a roadside stop. The likely outcome is a fine and a requirement to remove the film and bring the vehicle into compliance. Wyoming's enforcement environment may vary somewhat between urban and rural counties, but the statutory requirement applies uniformly across the state.

Because Wyoming is a fairly permissive state with a 28% front-side limit, most aftermarket tint jobs that target a medium to light darkness level will clear the legal threshold. The greater risk of a violation typically comes from very dark or reflective films that exceed the 20% reflectance cap or go below the 28% VLT on the front side.

If you want to tint your windows in Wyoming

Choose your tint level based on where in your vehicle you are applying it. For front side windows, any film that keeps combined VLT at 28% or above is legal for all vehicle types. For back side and rear windows on a sedan, you still need 28% or above. If you drive an SUV, truck, or van, you have more freedom: any tint darkness is legal on windows behind the driver as long as you have dual outside mirrors.

Before scheduling installation, confirm with your installer that the VLT rating applies to the combined reading of the film plus your vehicle's factory glass. Many modern vehicles come with factory glass that already reduces transmission by 10 to 20%, so a film rated at 35% VLT on plain glass might produce a combined reading below 28% on a vehicle with tinted factory glass. Your installer should measure the existing glass before recommending a film specification.

Avoid any film with luminous reflectance above 20%, including chrome, mirror, or highly metallic films. These are non-compliant on all windows under Wyoming law regardless of the VLT reading. After installation, ask your installer to meter all windows and provide a written record of the readings. Keep that document in your vehicle.

If you have dual outside mirrors and drive a multipurpose vehicle, document that setup as well. The mirror requirement is what enables the any-darkness exception on rear windows, and an officer assessing your vehicle should be able to verify the mirrors are present and functioning.
