Texas window tint law allows different darkness levels depending on which windows you tint
Texas does not ban window tint outright. Instead, the state sets minimum light transmittance (VLT) requirements — the percentage of visible light that must pass through the glass. If your tint meets these thresholds, you can legally drive on Texas roads. The rules differ by window location and vehicle type, and a few specific exemptions exist for medical reasons.
The key distinction is between sedans and SUVs or vans. Sedans have stricter limits on rear windows than larger vehicles do. Front windshields face the strictest rules across all vehicle types. Understanding where you can and cannot tint prevents a traffic stop and a fine.
Key Takeaways
- Front windshields must allow at least 70 percent of light through in all vehicles; tinting only the top visor strip above the AS-1 line is permitted.
- Front side windows must allow at least 25 percent light through in sedans and SUVs and vans (the same rule applies to both).
- Rear windows and rear windshields can be completely dark in SUVs and vans, but sedans must allow at least 25 percent light through the rear windows.
- Medical exemptions for light-sensitive conditions require a signed statement from a licensed physician and must be carried in the vehicle.
- Law enforcement can measure tint darkness with a light meter during a traffic stop, and non-compliant tint can result in a ticket and removal order.
Front windshield tint rules in Texas
Your front windshield can only be tinted across the top visor strip — the area above the manufacturer's AS-1 line (usually marked on the glass). This strip can be any darkness level. The rest of the windshield must allow at least 70 percent of light to pass through, which means you cannot explore a dark tint to the main driving area.
The 70 percent rule is the strictest in the state because law enforcement needs to see into the vehicle from the front. Even if you see other vehicles with darker front windshields, those drivers are in violation and subject to a ticket. The fine for non-compliant front windshield tint in Texas is typically $100 to $200, plus the cost of removal.
Side window tint limits for sedans versus larger vehicles
Texas treats sedans differently from SUVs, vans, and pickup trucks on side windows. For a sedan, both front and rear side windows must allow at least 25 percent of light through. For SUVs, vans, and pickup trucks, the front side windows must also allow at least 25 percent through, but the rear side windows can be completely dark.
This distinction matters because many people assume all vehicles follow the same rules. If you own a sedan and want darker tint on the rear side windows, you are limited to 25 percent VLT. If you own an SUV or van, you have more flexibility on the rear. Tell your tint installer your vehicle type and which windows you want tinted, because the installer needs to know the legal limits for your specific vehicle.
Rear window tint rules and the sedan exception
Rear windshields follow the same pattern as rear side windows. In SUVs and vans, the rear windshield can be completely dark. In sedans, the rear windshield must allow at least 25 percent light through. This rule exists because sedans have less visibility out the back than larger vehicles, and the state wants to preserve some light transmission to aid the driver.
If you own a sedan and want to tint the rear window darker than 25 percent, you will need a medical exemption (see below). Otherwise, the tint must meet the 25 percent threshold. Many tint shops can measure your vehicle's current tint with a light meter to confirm whether it is compliant before you drive away.
Medical exemptions and how to obtain one
Texas allows darker tint if you have a medical condition that makes you light-sensitive. Conditions that may have access to include lupus, porphyria, xeroderma pigmentosum, and severe photophobia. To use this exemption, you need a signed statement from a licensed physician stating that you have a medical condition requiring reduced light exposure while driving.
The physician's statement must be carried in your vehicle at all times. If a law enforcement officer stops you for tint that appears non-compliant, you can show the statement, and the officer should not issue a citation. The statement itself does not have to be registered with the state — you straightforward keep it in the car. If your condition changes or you no longer need the exemption, you should remove the tint or obtain new tint that meets the standard limits.
How law enforcement measures tint darkness
Police officers use a device called a light meter or tint meter to measure the percentage of light passing through your windows during a traffic stop. The meter shines light through the glass and reads the VLT percentage. If the reading falls below the legal threshold for that window, the officer can issue a citation for illegal tint.
The measurement is taken from outside the vehicle, and the process takes only a few seconds per window. If you receive a citation, you have the option to remove the tint and show proof of removal to the court, which often results in the fine being dismissed. Some courts allow you to have the tint measured again by a certified shop and present that measurement as evidence of compliance.
What happens if your tint is non-compliant
A citation for illegal window tint in Texas is typically a misdemeanor traffic violation. The fine ranges from $100 to $200, depending on the county and whether it is a first offense. The citation will also include an order to remove the non-compliant tint within a set timeframe, usually 10 to 30 days.
If you do not remove the tint by the important date, you can receive an additional citation for failure to comply. Some drivers choose to fight the citation in traffic court by presenting evidence that the tint meets the legal standard, though this requires a certified measurement from a tint shop. The safest approach is to have your tint measured before installation and to work with a shop that guarantees compliance with Texas law.
Frequently Asked Questions
Can I tint my windshield below the AS-1 line?
No. Only the top visor strip above the AS-1 line can be tinted to any darkness level. The rest of the windshield must allow at least 70 percent light through. This rule applies to all vehicles in Texas.
What is the difference between 25 percent and 35 percent tint?
The percentage refers to visible light transmittance (VLT). A 25 percent tint allows one-quarter of light through and blocks three-quarters. A 35 percent tint allows more light through and is lighter in appearance. Texas law sets 25 percent as the minimum for front and rear side windows in sedans, so 35 percent tint is also legal.
Do I need to register my medical exemption with the state?
No. You only need to carry the signed physician's statement in your vehicle. There is no state registration or permit process for medical tint exemptions. Keep the statement accessible so you can show it to an officer if stopped.
Can I have my tint measured before I buy it?
Yes. Many tint shops will measure your vehicle's current windows or test tint samples with a light meter before installation. Ask the shop to measure and document the VLT percentage so you have proof of compliance.
Are there different rules for commercial vehicles?
Texas tint law applies to all passenger vehicles, including commercial vehicles used for personal transport. Vehicles registered as commercial trucks or buses may have different rules — check with your local law enforcement or the Texas Department of Motor Vehicles if you operate a commercial vehicle.
