Texas Window Tint Laws (2026): Legal VLT Limits

Texas law requires front side windows to allow at least 25% of visible light through (25% VLT minimum). Back side and rear windows may be tinted to any darkness when the vehicle has dual outside mirrors, giving most drivers considerable flexibility behind the driver's seat.

What is the legal tint limit in Texas?

Texas sets a 25% VLT minimum for front side windows, meaning the film and glass combined must allow at least 25% of visible light to pass through. A higher VLT percentage is lighter; a lower percentage is darker. So 25% is the darkest shade legally permitted on your front windows, and 70% (nearly clear) would be much lighter.

Back side windows (the windows behind the driver on sedans, SUVs, vans, and trucks) may be tinted to any darkness under Texas law. The rear window may also be any darkness, but only if the vehicle is equipped with dual outside mirrors on both sides. Without dual mirrors, the rear window must meet the same 25% VLT minimum as the front side windows.

The dual-mirror rule ensures the driver can always see rearward, even when the rear glass is blacked out. If you plan on very dark rear tint, confirm your vehicle has functional mirrors on both sides.

Texas also caps window reflectance at 25%. Reflective or metallic films that bounce more than 25% of light back are not legal on any window. Mirrored-appearance films that are extremely reflective are prohibited. Beyond reflectivity, Texas bans specific tint colors outright: red, blue, and amber tint films are not permitted on any window.

Windshield tint rules in Texas

The windshield receives the most restrictive treatment under Texas Transportation Code Section 547.613. Aftermarket tint on the main windshield surface is not permitted below the AS-1 line or beyond the top 5 inches, whichever is lower on the glass. Only a non-reflective sun strip in that upper zone is allowed.

There is one notable exception: clear UV-filtering film that does not reduce visible light transmission may be applied to the entire windshield. These films are designed to block ultraviolet radiation without visibly darkening the glass, and they are fully legal in Texas as long as they do not alter the appearance of the glass or reduce VLT.

The 25% reflectance cap and the ban on red, blue, and amber colors apply to the windshield strip as well. A dark or colored band across the top of your windshield would not meet these requirements.

Medical exemptions

Texas allows a medical-necessity exemption for drivers or regular passengers who have a medical condition that makes them sensitive to sunlight. Qualifying conditions typically involve photosensitivity, lupus, or other conditions documented by a licensed physician.

To obtain an exemption, the driver or vehicle owner must have physician documentation of the medical need. The paperwork certifying the exemption should be kept in the vehicle whenever it is on the road, because law enforcement may request it during a stop. The exemption permits film darker than the standard 25% VLT limit on the windows specified in the physician's documentation.

If you believe you qualify, speak with your physician about completing the required certification. The Texas Department of Public Safety (DPS) administers tint regulations, and the DPS or your local county tax office can clarify the current form requirements.

How tint is measured and certified

Texas uses a VLT meter (sometimes called a tintometer or photometer) to measure the combined light transmission through the glass and film together. The meter is placed on the window edge and reads the percentage of light passing through. Both the film itself and the factory glass tint count toward the total, so a car with factory-tinted glass may have very little room for additional aftermarket film before hitting the 25% floor.

Texas law requires a compliance label (a sticker) placed between the film and the glass on the driver's side window. The label must cite Texas Transportation Code Chapter 547 and state the VLT percentage and reflectance values of the film. The label is the primary way an officer or inspector confirms the tint is legal without needing a meter at every stop.

When choosing a tinter, ask for the manufacturer's certificate of compliance showing the film's VLT rating and reflectance. Keep that document in the vehicle along with any medical paperwork. A reputable installer will apply the label automatically and provide you with the certificate.

Texas does not specify an official measurement tolerance in the statute, so installers should target a noticeable margin above the 25% minimum to account for normal variation.

Penalties for illegal tint in Texas

Illegal window tint in Texas primarily results in a vehicle inspection failure. Texas requires annual safety inspections, and a vehicle with non-compliant tint will not pass. The inspection failure means you cannot legally register or re-register the vehicle until the tint is brought into compliance.

In addition to the inspection consequence, DPS standards authorize a fine. The specific fine amount is set under DPS enforcement guidelines rather than a fixed statutory dollar figure. Officers can also issue a citation during a roadside stop if they observe or measure illegal tint. If cited, you will typically need to remove the offending film and provide proof of correction to resolve the ticket.

Repeat violations or failure to correct the problem can lead to escalating consequences. The simplest path forward is to remove and replace non-compliant film before an inspection or stop occurs.

If you want to tint your windows in Texas

Start with the legal numbers: 25% VLT minimum on front side windows, any darkness on back and rear (with dual mirrors), 25% maximum reflectance, and no red, blue, or amber film on any window. If your vehicle already has factory-tinted glass, measure or ask the dealer for the factory VLT before adding aftermarket film. Many factory glass panels transmit 70-80%, leaving room for a 35% or 50% aftermarket film while staying legal.

Choose a licensed installer who is familiar with Texas requirements. Ask them to install the required compliance label (citing TRC Chapter 547) between the film and glass on your driver's window, and ask for a written manufacturer's certificate showing the film's VLT and reflectance specs. Keep both in your vehicle.

If you have a qualifying medical condition, get your physician's documentation before installation so the installer knows what exemption windows to apply, and carry that paperwork whenever you drive.

Finally, confirm your vehicle has dual outside mirrors before blacking out the rear window entirely. Without those mirrors, the rear window must also meet the 25% VLT minimum.
