Texas sets a 25% limit beside the driver and on the windshield strip. Behind the driver, any shade is allowed, the back glass too with a mirror on each side. Every window, in plain words, checked against the statute.
A strip can run across the top of the windshield, down to the AS-1 line marked on the glass or 5 inches from the top, whichever is closer to the top. Film and glass together must let through 25% or more of the light, reflect 25% or less, and be any color but red, blue or amber.
The windows either side of the driver, wing vents included, need film and glass together to let through 25% or more of the light and reflect 25% or less. Factory glass already holds some light back, so the reading is taken through both. 35%, 50% and 70% are the shades to look at here.
Every side window behind the driver can take any shade, on cars, trucks, SUVs and vans alike. 5%, 15% and 20% all belong here, and so does anything lighter.
The back glass can take any shade as long as the vehicle has an outside mirror on each side, giving the driver a view of the road at least 200 feet behind. Most vehicles already do.
Medical exemption. Texas law gives a defense when the driver, or a passenger in the vehicle at the time, must be shielded from direct sun for a medical reason. The Texas Department of Public Safety asks for a signed statement from a licensed physician or optometrist, kept in the vehicle. Tell us about it when you ask for your price.
Texas Transportation Code §547.613, Restrictions on Windows, with §547.609 for the label: statutes.capitol.texas.gov (read October 7, 2026). A plain-words guide, not legal advice; where they differ, the statute governs.
The front side windows need film and glass together to let through 25% or more of the light and reflect 25% or less. Factory glass already blocks some light, so a 35% film reads darker once it’s on. We check the reading on your own glass before cutting.
