Legal window tint in Texas starts at 25% VLT (visible light transmission) for the front side windows and the narrow strip across the top of the windshield. Behind the driver, the rules loosen considerably: rear side windows have no darkness limit, and the back windshield can be any shade as long as your vehicle has a working outside mirror on each side.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows Go darker than those numbers allow on a restricted window and you’re looking at a failed state inspection, a misdemeanor citation, or both.
Windshield
Tint film on the windshield is allowed only across the top. It cannot extend below the AS-1 line, a small marking etched into the glass by the manufacturer, or more than five inches down from the top edge, whichever leaves less tinted area.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows On a windshield with no AS-1 line, the five-inch limit controls.2Department of Public Safety. Window Tinting Standards
That strip must still let at least 25% of light through once the film and glass are measured together, and it cannot reflect more than 25% of light. Red, blue, and amber film is prohibited.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows
Front Side Windows
The two windows beside the driver and front passenger must let at least 25% of light through, measured with the film and glass combined. Reflectivity on these windows also cannot exceed 25%.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows Fall below 25% VLT and the window fails inspection, regardless of the vehicle’s model year.2Department of Public Safety. Window Tinting Standards
Factory glass already blocks some light on its own, so a film sold as “25% VLT” will usually read lower once applied. A reputable installer accounts for this before cutting the film, but it’s worth asking before you commit.
Rear Side Windows and Back Windshield
Texas does not set a minimum VLT for any side window behind the driver. You can go as dark as you want on those windows, including a full blackout.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows
The back windshield has no VLT limit either, on one condition: the vehicle must have an outside mirror on each side that gives a view of at least 200 feet of roadway behind it.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows Nearly every modern vehicle meets that standard from the factory. If yours has only one outside mirror, the rear windshield has to meet the same 25% rule as the front side windows.
Color and Reflectivity Limits Apply to Every Window
Two restrictions follow the tint everywhere, not just the windows up front. No film on any window may reflect more than 25% of light, which rules out mirror-finish products.2Department of Public Safety. Window Tinting Standards And red, amber, and blue film is banned on every window regardless of VLT percentage or position, because those colors can be confused with emergency lighting and traffic signals.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows Grey, charcoal, and smoke are the standard neutral options.
The Certification Label
Every aftermarket tint job needs a compliance label installed between the film and the glass, at the rearmost bottom corner of the driver’s side window.2Department of Public Safety. Window Tinting Standards The label has to be legible and show the film’s light transmission and reflectance values.3State of Texas. Texas Transportation Code Section 547.609 – Required Label for Sunscreening Devices
Required wording is “Complies with TRC Chapter 547” or an equivalent reference to Section 547.613(b). Including the installer’s or manufacturer’s name is optional.2Department of Public Safety. Window Tinting Standards A missing label can fail an inspection even when the tint shade itself is legal. If a professional installer puts film on your car without the label, the installer faces a misdemeanor fine of up to $1,000.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows
Medical Exemption for Darker Tint
If a medical condition requires you to limit sun exposure, you can run tint darker than 25% VLT on windows that would otherwise be restricted. Severe light sensitivity and photosensitive skin disorders are among the qualifying reasons.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows
To qualify, you need a signed statement from a licensed physician or optometrist. It should identify you with reasonable specificity and explain why darker film is medically necessary in the doctor’s professional opinion.2Department of Public Safety. Window Tinting Standards Keep the original in the vehicle. You’ll show it at traffic stops and at your annual inspection, where the inspector logs it in the state database.4Texas Department of Public Safety. Notice Window Tint Medical Exemption
One point surprises people: the Texas Department of Public Safety stopped issuing formal Window Tint Exemption Certificates in January 2019 and no longer accepts or reviews applications.2Department of Public Safety. Window Tinting Standards The doctor’s letter is now the entire process. There is no state card, no portal, and no certificate to apply for.
Other Vehicles That Are Exempt
A few categories of vehicles sit outside the standard tint rules altogether:2Department of Public Safety. Window Tinting Standards
- Vehicles maintained by a law enforcement agency and used for law enforcement purposes.
- Vehicles that carry passengers for a fee on a regular basis, including taxis, limousines, and buses.
Vehicles not registered in Texas are also exempt from the state’s rules, and factory tint that meets federal manufacturing standards passes inspection without further scrutiny.1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows
Penalties and What a Stop Looks Like
Driving with non-compliant tint is a misdemeanor under Section 547.613(a).1State of Texas. Texas Transportation Code Section 547.613 – Restrictions on Windows Most tint citations function as fix-it tickets in practice: strip or replace the film, show the court proof, and the fine is reduced or dismissed. You still absorb the removal and reinstall costs.
A failed state inspection hits sooner. The vehicle can’t legally be driven on Texas roads until the tint is corrected and the car passes a re-inspection. Between removal, new film, and the second inspection fee, cheap illegal tint often turns into the more expensive option.
A visible tint violation gives an officer legal grounds to pull you over. Many Texas departments carry handheld tint meters that read VLT in about four seconds, and the roadside reading is what the citation will reflect, not whatever number your installer quoted.
Commercial Motor Vehicles Follow Stricter Federal Rules
If you drive a commercial motor vehicle, federal law layers on top of the Texas limits. Under 49 CFR 393.60, the windshield and the windows immediately beside the driver have to allow at least 70% of light through, nearly three times what Texas requires for passenger cars.5eCFR. 49 CFR 393.60 – Glazing in Specified Openings Windows behind the driver on a commercial vehicle have no federal VLT limit. Aftermarket tint on the front glass that drops below 70% can trigger violations during DOT inspections and roadside checks.
