Texas Window Tint Laws Explained: Legal VLT Limits for 2026

Texas tint law is simpler than most drivers think, but the details decide whether you pass inspection. Here is the short version, then the specifics, from installers who tint Texas vehicles every week.

The Short Answer

In Texas, your front side windows must let in more than 25% of visible light. Windows behind the driver can be as dark as you like on most passenger vehicles. The windshield can only be tinted above the AS-1 line, and no window may be more than 25% reflective.

What VLT Means

VLT stands for visible light transmission: the percentage of light that passes through the glass and film together. Lower numbers are darker. A 5% film is limo tint; a 70% film looks nearly clear.

Texas Limits, Window by Window

Front side windows must allow more than 25% of light through. Rear side windows can be any darkness. The back window can also be any darkness if the vehicle has outside mirrors on both sides; without both mirrors, it must stay above 25% as well. Reflectivity may not exceed 25% on any tinted window, and red, amber, and blue tints are not permitted.

Windshield Rules

Tint is only allowed above the AS-1 line (or the top five inches if the line is not marked), and it must be non-reflective. Clear UV film below the AS-1 line can qualify as a medical exception; standard shade film there will fail inspection.

Medical Exemptions

Texas allows darker tint with a signed medical exemption statement from a licensed physician or optometrist. Keep the documentation in the vehicle; the exemption applies to the patient’s vehicle, not every car you own.

What Inspection Actually Checks

Texas safety inspections use a tint meter on the front side windows. Film that measures at or below 25% VLT fails, and remember the meter reads glass plus film together: factory glass already blocks a few percent, so a 28% film on tinted glass can measure under the limit.

Picking a Shade That Looks Right and Passes

For front windows, a quality ceramic film in the 30 to 35% range reads dark, beats the heat, and passes with margin. Behind the driver, most of our Dallas-Fort Worth clients run 15 to 20% for the factory-limo look. Ceramic film matters more than darkness in Texas: it rejects far more heat at the same VLT than dyed film.
