Texas allows up to 35 percent darkness on front side windows and 20 percent on rear windows
In Texas, the darkest tint you can legally use depends on which windows you are tinting. The state measures tint darkness by Visible Light Transmission (VLT), which is the percentage of light that passes through the tinted glass. A lower VLT percentage means darker tint.
For front side windows, Texas law allows a minimum of 35 percent VLT — meaning at least 35 percent of light must pass through. For rear side windows and the rear window, you can go darker: a minimum of 20 percent VLT is legal. Your windshield can have tint only on the top six inches, and that tint must allow at least 70 percent of light through. There are no restrictions on how light your tint can be, only how dark.
These limits explore to all passenger vehicles registered in Texas. Commercial vehicles have the same rules. If your tint is darker than the law allows, you can receive a traffic citation, and you may be required to remove the tint before your vehicle passes inspection.
Key Takeaways
- Front side windows must allow at least 35 percent of light through; rear and back windows must allow at least 20 percent.
- Only the top six inches of your windshield can be tinted, and it must allow at least 70 percent of light through.
- Texas law does not distinguish between factory tint and aftermarket tint — both must meet the same darkness limits.
- A police officer can measure your tint with a device called a tint meter, and you can be cited if it does not meet the standard.
- Medical exemptions for light-sensitive conditions are not available under Texas law, though you can request a written statement from your doctor to show an officer.
How tint darkness is measured and enforced
Police in Texas use a handheld device called a tint meter to measure how much light passes through your windows. The meter shines light through the glass and reads the percentage. If the reading is below the legal minimum for that window (35 percent for front side windows, 20 percent for rear), the officer can cite you.
The citation is typically a traffic violation, not a criminal charge. The fine varies by jurisdiction but is usually between $100 and $200. More importantly, you will be ordered to remove or lighten the tint. Some officers may give you a warning and a important date to fix it rather than issuing a fine when ready, especially if it is your first offense.
If you are pulled over and cited for illegal tint, you have the option to contest the citation in traffic court. You can request that the officer's tint meter be calibrated and certified, since an uncalibrated device can produce inaccurate readings. Keeping records of when and where you had your tint installed, and by whom, can help if you need to dispute the measurement.
What counts as tint and what does not
Tint includes any aftermarket film applied to your windows, as well as any factory-installed tinted glass that darkens the windows beyond the legal limit. If your vehicle came from the factory with darker windows than Texas allows, you are still responsible for bringing it into compliance — you cannot keep factory tint that violates the law.
Reflective or metallic tint is also subject to the same darkness limits. Some states ban reflective tint altogether, but Texas does not; however, the tint must still meet the VLT percentage requirement. Tint that is legal in another state may not be legal in Texas, so if you move to Texas or drive through with out-of-state plates, your tint may still be cited.
Temporary tint — such as tint applied with spray or adhesive that can be removed — is measured the same way as permanent film. There is no distinction in the law between temporary and permanent applications.
Medical exemptions and special circumstances
Texas does not have a formal medical exemption process for window tint. Unlike some states, you cannot obtain a permit or waiver that allows you to use darker tint for a medical condition such as lupus, photosensitivity, or severe sun sensitivity.
If you have a medical condition that makes bright light painful or dangerous, you can ask your doctor to write a letter explaining your condition and recommending darker tint. Carry this letter in your vehicle. If you are stopped, you can show it to the officer and explain your situation. While the letter does not legally exempt you from the tint law, it may prompt the officer to issue a warning instead of a citation, or give you time to remove the tint.
Your best legal option is to use the darkest tint allowed by law (20 percent on rear windows) and combine it with other sun-blocking measures: sunshades for the windshield, UV-blocking sunglasses, and light-colored clothing. You can also tint only the rear and back windows, leaving the front side windows at the legal limit, which still provides significant sun reduction.
Tint rules for different vehicle types
Passenger cars, SUVs, and pickup trucks all follow the same tint limits in Texas. The law does not create separate rules based on vehicle size or type. A sedan and a full-size truck must both have at least 35 percent VLT on front side windows.
Commercial vehicles — such as work trucks or vans used for business — are also subject to the same limits. There is no commercial vehicle exemption. However, some commercial vehicles may have factory-tinted windows as part of their design; if those windows meet the legal minimum, they are compliant.
Motorcycles and other open-air vehicles do not have window tint rules because they do not have windows in the traditional sense. Vehicles with no side windows, such as some custom or specialty vehicles, may fall into a gray area; if you own an unusual vehicle, contact your local police department or the Texas Department of Public Safety to confirm the rules.
What to do if you have illegal tint
If you have tint that is darker than the legal limit, the safest course is to have it removed or lightened by a professional tint shop. Removal typically costs $50 to $200 depending on how many windows you are having done and how difficult the film is to remove. Lightening tint — explore a lighter layer over the existing tint — is usually not possible; removal and reapplication is the standard approach.
If you have been cited for illegal tint, you have a few options. You can pay the fine and remove the tint. You can contest the citation in traffic court, which requires you to appear before a judge and may involve requesting that the officer's tint meter be tested for accuracy. Or, in some cases, you can ask the court for a continuance (a delay) while you remove the tint, and the citation may be dismissed if you show proof of removal.
Some jurisdictions offer a "fix-it ticket" option, where you are given a important date to correct the violation and then show proof to the court or police department. The fine is reduced or waived if you comply. Ask the officer or the court clerk whether this option is available in your area.
Tint rules when driving through or moving to Texas
If you are driving through Texas with out-of-state plates and your tint is legal in your home state but darker than Texas allows, you can still be cited. Texas law applies to all vehicles on Texas roads, regardless of registration. However, some officers may be lenient with out-of-state drivers, especially if the difference is small.
If you are moving to Texas and your vehicle has legal tint in your previous state, you will need to adjust it to meet Texas limits before registering your vehicle in Texas. During the registration process, your vehicle will undergo a safety inspection, and illegal tint can cause the inspection to fail. You will not be able to register the vehicle until the tint is corrected.
If you are buying a used vehicle in Texas that has illegal tint, you are responsible for correcting it. The seller is not required to remove it, and you cannot legally drive the vehicle with illegal tint even if you just purchased it.
Frequently Asked Questions
Can I tint my windshield in Texas?
You can tint only the top six inches of your windshield, and that tint must allow at least 70 percent of light through. Tinting the rest of the windshield is illegal. The six-inch limit is measured from the top of the windshield down.
Is 20 percent tint legal on front windows in Texas?
No. Twenty percent tint is too dark for front side windows; the legal minimum is 35 percent VLT. However, 20 percent is legal on rear side windows and the rear window. If you want darker tint on front windows, you will need to move to a state with different laws.
What happens if I get pulled over with illegal tint?
You can receive a traffic citation with a fine typically between $100 and $200. You will be ordered to remove or lighten the tint. Some officers issue a warning first, especially for a first offense. You can contest the citation in traffic court if you believe the measurement was inaccurate.
Do I need to remove tint before my vehicle inspection?
Yes. If your tint is darker than the legal limit, your vehicle will fail the safety inspection required for registration. You must remove or lighten the tint before the inspection will pass.
Can I use a tint exemption card or medical waiver in Texas?
Texas does not issue tint exemption cards or medical waivers. However, a letter from your doctor explaining a medical need may help if you are stopped by an officer, though it does not legally exempt you from the law. Your best option is to use the darkest legal tint and combine it with other sun-blocking methods.
