Texas allows window tint on your car, but only within specific limits that vary by window location
Texas law permits aftermarket window tint on passenger vehicles, but the state sets darkness limits measured in visible light transmission (VLT) — the percentage of light allowed through the tinted glass. The rules differ depending on which windows you tint, and violations can result in a fix-it ticket or a fine of up to $200.
The state does not require you to register your tint or obtain a permit before installation. However, law enforcement can measure your tint's darkness during a traffic stop, and you are responsible for knowing whether your vehicle meets the law. Texas also allows medical exemptions for drivers who need darker tint due to a documented skin condition or light sensitivity, but you must carry proof of the exemption in your vehicle.
Key Takeaways
- Front side windows must allow at least 25 percent of light through; rear and back windows can be any darkness, including fully opaque.
- The windshield can have tint only in the top 5 inches, and that tint must not reduce light transmission below 70 percent.
- Texas does not require pre-approval or registration of window tint, but police can measure darkness during a stop and issue a citation if it violates the law.
- Drivers with a medical condition affecting light sensitivity can obtain an exemption letter from a physician, which must be carried in the vehicle at all times.
- A fix-it ticket allows you to remove or lighten the tint and show proof to the court, usually without paying the full fine.
Front side windows: the 25 percent rule
Your front side windows — the glass on either side of the driver and front passenger — must allow at least 25 percent of visible light to pass through. This is the strictest limit in Texas and applies to both the driver's side and the passenger's side. If your tint is darker than 25 percent VLT, you are in violation, even if the tint was installed legally in another state.
The 25 percent threshold is measured using a light meter, a handheld device that law enforcement carries. The measurement is taken from outside the vehicle looking in. If you are unsure whether your existing tint meets the standard, a tint shop can measure it for you before you drive the vehicle on public roads.
Rear and back windows: no limit
Texas places no darkness restriction on rear side windows or the rear window. You can tint these windows as dark as you want, including limo tint (fully opaque). This applies to sedans, SUVs, trucks, and hatchbacks — any window behind the driver's seat has no VLT requirement.
This flexibility is one reason many drivers choose to tint only the rear windows if they want maximum privacy without legal risk. Rear tint also reduces heat inside the vehicle and protects the interior from UV damage, and Texas law does not penalize you for doing so.
Windshield tint: the 5-inch band rule
You can tint only the top 5 inches of your windshield, measured from the top of the glass downward. Any tint applied below that line is illegal. The tint you do explore to the top 5 inches must allow at least 70 percent of light through — darker than that violates the law.
The 5-inch band is designed to preserve the driver's forward vision while allowing some heat reduction at the top of the windshield. Many drivers use a clear protective film in this area instead of tint, which provides UV protection without darkness. If you have existing windshield tint that extends below the 5-inch mark, removing or lightening it is necessary to comply with Texas law.
Medical exemptions and how to obtain one
Texas law allows a medical exemption for drivers with a condition that requires protection from light — such as lupus, porphyria, severe photosensitivity, or certain eye conditions. If you have a may have access to condition, your physician can write a letter stating that you need darker window tint for medical reasons. This letter must be carried in your vehicle at all times.
With a valid medical exemption letter, you can tint your front side windows darker than 25 percent VLT. The exemption does not eliminate the need to show the letter to a police officer if you are stopped, and the letter must be current (most officers accept letters dated within the past year, though Texas law does not specify an expiration date). If you lose the letter or it expires, you no longer have legal protection for darker tint.
The exemption letter must come from a licensed physician and state that the driver has a medical condition requiring darker tint. It does not need to be notarized or filed with the state. Keep a copy in your vehicle and consider keeping a photo of it on your phone as backup.
What happens if you are cited for illegal tint
A police officer who observes tint darker than the legal limit can issue a citation. In most cases, this is a fix-it ticket — a notice to correct the violation and show proof of correction to the court. You typically have 10 days to remove or lighten the tint, then submit proof (such as a receipt from a tint shop or a photo showing the windows are now clear) to the court.
If you show proof of correction, the fine is usually dismissed or reduced to a small administrative fee. If you do not correct the violation or show proof, the citation becomes a regular traffic ticket with a fine up to $200. Some courts also allow you to appear in person and explain the correction to a judge rather than submitting written proof.
A tint violation is not a moving violation and does not add points to your driving record. However, it is still a traffic citation and will appear on your driving history. Repeat citations for the same violation may result in higher fines or the court requiring you to remove all aftermarket tint.
How tint darkness is measured and enforced
Law enforcement uses a light meter (also called a tint meter) to measure VLT. The device is placed against the outside of the window, and the reading shows what percentage of light passes through. The measurement is objective — if your tint reads below the legal limit for that window, you are in violation regardless of the brand or installation quality.
Not all police departments in Texas actively enforce tint violations. Enforcement varies by city and county. Some departments prioritize tint stops; others address it only during traffic stops for other reasons. If you live in an area with strict enforcement, darker tint increases your risk of a citation. If you live in an area with minimal enforcement, the risk is lower — but the law remains the same statewide.
Some tint shops advertise "legal tint" that is may provide to pass inspection. However, the only way to be certain is to have your tint measured with a light meter before you drive the vehicle. If you are unsure, ask the shop to measure your tint before you leave, or have it measured at a different shop for verification.
Frequently Asked Questions
Can I tint my windshield below the 5-inch line if I have a medical exemption?
No. The 5-inch windshield limit applies to all drivers, including those with medical exemptions. The exemption allows you to darken your front side windows beyond 25 percent VLT, but it does not extend to the windshield. Windshield tint below the 5-inch mark is illegal for everyone.
What if I bought my car with illegal tint already installed?
You are responsible for the tint on your vehicle, regardless of who installed it. If you are cited, you must correct the violation. The fastest solution is to have the tint removed or lightened by a tint shop, then show proof to the court. You may also have a claim against the seller or dealer if they misrepresented the vehicle's compliance with Texas law.
Do I need to notify the state if I get a medical exemption?
No. You do not register the exemption with any state agency. You straightforward carry the physician's letter in your vehicle. If you are stopped, show the letter to the officer. There is no state database or approval process — the letter itself is your proof.
Can I have different tint darkness on my left and right front windows?
Yes, as long as both windows meet the 25 percent VLT minimum. However, having noticeably different darkness on the two sides may draw attention during a traffic stop. For consistency and to avoid questions, most drivers choose the same tint level on both front side windows.
If I get a fix-it ticket, do I have to go to court?
Not necessarily. Most courts allow you to submit proof of correction by mail or online without appearing in person. Check the citation for instructions on how to submit proof. If the court requires an appearance, the citation will state that. In most cases, correcting the violation and submitting proof is enough to dismiss the fine.
