West Virginia Window Tint Laws Explained: Legal VLT Limits for 2026

Summer heat rolling through Charleston or up the river valleys makes a parked car feel like an oven, and the first question any driver asks is how dark the law will let them go. In West Virginia your front side windows can come down to 35% VLT, the back glass follows that same 35%, and the windshield stays clear except for a top strip. Here is the full picture, pulled straight from the code.

How dark can you legally tint in West Virginia?

Front side windows down to 35% VLT, rear windows down to 35%, and a clear windshield apart from the top band. West Virginia Code § 17C-15-36a, the state’s sun-screening-devices law, requires the side windows immediately right and left of the driver to allow at least 35% light and hold reflectivity to no more than 20%. The windows behind the driver and the rearmost window get the same 35% light floor and 20% reflectivity cap. On the windshield, film must be nonreflective, cannot be red, yellow, or amber, and may sit only along the top — no lower than the ASI line or 5 inches from the top, whichever is closer. The complete section is published on the West Virginia Legislature code site.

The tint stories West Virginia drivers get wrong

Myth: passenger cars and SUVs play by the same back-glass rule. Reality – they do not. The statute lifts the light-transmission requirement on windows behind the driver for trucks, buses, trailers, motor homes, and multipurpose passenger vehicles, so a Bronco can run dark out back while a sedan is held to 35%.

Myth: a 20% film is fine as long as it is not mirrored. Reality – 20% VLT on the front sides is illegal here. The floor is 35%, and the 20% figure in the law is the reflectivity cap, not a darkness limit. Mixing those two numbers up is how a lot of tickets happen.

Myth: there is no legal way to go darker for a health condition. Reality – West Virginia does write in a medical exemption. With a signed affidavit from a licensed physician or optometrist kept in the vehicle, the transmittance and reflectance limits can be exceeded for that driver.

Reflectivity, color, and the windshield rule

The reflectivity ceiling sits at 20% on the front sides and the rear, which knocks out mirror-finish film even when it passes the darkness test. Windshield film has to be nonreflective and stay out of the red, yellow, and amber range, living only in that top band above the ASI line. All of it rides on the federal baseline: glazing has to meet the National Highway Traffic Safety Administration’s standard in FMVSS 205 (49 CFR 571.205), the rule that defines AS-1 markings and certified glass. A correct tint job keeps you square with both.

Penalties and what you must keep

Running illegal sun-screening in West Virginia is a misdemeanor, and the statute also puts requirements on the people who sell and install the film.

What to do: have your installer use film carrying the manufacturer’s label — the law requires that compliance sticker, with the maker’s name and light-transmission percentage, in the lower corner of the glazing. Keep both outside mirrors mounted if anything behind the driver is tinted, and if you qualify medically, store the physician or optometrist affidavit in the vehicle. Those documents are what turn a stop into a quick check instead of a fine. The West Virginia DMV handles inspection and registration questions.
