Window Tint Law in Texas: VLT Limits, Exemptions, and Penalties

Under Texas window tint law, your front side windows must allow at least 25% of visible light to pass through the film and glass combined, and the film cannot reflect more than 25% of the light that hits it. The windshield only accepts tint in a narrow strip at the top. Rear side windows and the back glass have no darkness limit as long as the vehicle has a working mirror on each side. Driving with tint that breaks these rules is a misdemeanor and will cause your car to fail its annual safety inspection.¹

Front Side Windows

The driver and front-passenger windows carry the strictest limits for aftermarket film. The tint and the factory glass together must let at least 25% of visible light through, and the film cannot reflect more than 25% of the light striking its surface.¹

That 25% VLT floor is a combined reading, not a spec on the film alone. A film sold as “25% VLT” applied over factory glass that already filters some light can push the finished window below the legal line, so ask the installer to measure the window with a light meter after the film cures. Wing vent windows, if your vehicle has them, follow the same 25% VLT and 25% reflectance standards.¹

Windshield

Aftermarket tint on the windshield is confined to a strip at the top of the glass. The strip ends at the AS-1 line, a short mark the manufacturer etches or prints into the glass. If the windshield has no AS-1 line, the film cannot extend more than five inches down from the top. Whichever of those two boundaries sits higher on the glass is the one you follow.¹ Within that strip, the film still has to meet the 25% VLT and 25% reflectance limits.

Red, blue, and amber film is prohibited on the windshield to avoid confusion with emergency-vehicle lighting.²

A clear, untinted UV-blocking film is permitted across the entire windshield without any medical exemption.² Federal safety standards require windshields to transmit at least 70% of visible light, so a full-windshield film has to stay comfortably above that floor.³

Rear Side Windows And Back Glass

Behind the driver, Texas is permissive. Side windows from the B-pillar back have no VLT or reflectance limit at all. You can run limo-dark film, including full blackout, on every rear side window. The statute writes this exemption for passenger cars and separately restates it for multipurpose vehicles, so sedans, trucks, and SUVs all get the same treatment on the rear glass.¹

The rear windshield is also exempt, but with one condition: the vehicle must have an outside mirror on each side that gives the driver a view of the road at least 200 feet behind the car.¹ Nearly every passenger vehicle on the road meets this. If a side mirror is missing or broken, the rear windshield reverts to the standard 25% VLT and 25% reflectance limits until the mirror is replaced.

Reflectance Cap

The 25% reflectance ceiling applies to every window where tint is allowed, no matter how light or dark the film is. That means the windshield strip, both front side windows, and any rear glass where you add film.² Mirror-finish and heavily metallic films can throw glare at oncoming drivers, which is the hazard this cap addresses. Some metallic films clear the VLT test but fail on reflectance, so confirm both numbers with your installer before you commit.

Factory Privacy Glass And Out-of-State Vehicles

Factory-installed privacy glass that meets federal glazing standards sits outside the state tint rules, even when it looks quite dark.¹ That is why new trucks and SUVs can roll off the dealer lot with rear glass that would be illegal as aftermarket film. Factory privacy glass typically measures between 15% and 25% VLT, but because the automaker installed it to federal specs, Texas does not regulate it further.

Vehicles not registered in Texas are also exempt from the state’s tint requirements.¹ If you drive in from another state with tint that is legal where you registered, you will not be cited here. That changes the moment you register the vehicle in Texas.

Medical Exemption

If you have a medical condition such as lupus, melanoma, or severe photosensitivity, you can run front side window tint darker than 25% VLT. You need a signed statement from a licensed physician or optometrist that names the person who needs the protection and states that the darker tint is medically necessary.²

The Texas Department of Public Safety stopped issuing formal Window Tint Exemption Certificates in 2019, so the physician’s letter now serves as the proof on its own.² Keep the letter in the vehicle at all times. You will need to show it during a traffic stop and during the annual safety inspection. Without the letter on hand, officers and inspectors will treat the tint as non-compliant.

Compliance Label

Every aftermarket tint job must include a compliance label placed between the film and the glass on each tinted window. The label has to be legible, show the film’s light transmission and reflectance values, and confirm compliance with Section 547.613.⁴ Inspectors look for it so they can confirm the install without pulling out a meter.

An installer who skips the label commits a separate misdemeanor, with a fine of up to $1,000.¹ That penalty is on the installer rather than the owner, but a missing label can still fail your inspection even if the film itself is within limits. If your installer did not apply one, go back and ask for a label before your next inspection.

Penalties And Inspection Failure

Window tint is part of the Texas annual vehicle safety inspection. Inspectors measure VLT on the front side windows, check for prohibited windshield colors, and verify compliance labels. Non-compliant tint fails the inspection, and the vehicle cannot be legally driven until the tint is corrected and the car passes a re-inspection.²

On the road, illegal tint is a misdemeanor under the Transportation Code.¹ An officer can stop you for a tint violation and issue a citation. Fines on a first offense tend to be modest and climb with repeat violations. A tint ticket also goes on your driving record, which can push insurance rates up.

Some officers treat a tint citation as a fix-it ticket, giving you a window to remove or replace the film and then dismiss the charge. That is an informal practice, not a legal right, and it varies by jurisdiction and officer. The safer play is to confirm your tint meets the limits before you drive, rather than relying on leniency after the stop.
