Texas allows window tint on your car, but the darkness is limited and varies by window location

Texas law permits you to tint your vehicle windows, but the state sets specific limits on how dark the tint can be. The darkness is measured as visible light transmission (VLT) — the percentage of light allowed to pass through the tinted window. The darker the tint, the lower the VLT percentage. Texas does not ban tint entirely, but it does restrict how much you can use depending on which windows you are tinting.

The rules are different for the front windshield, front side windows, and rear windows. Front windows have stricter limits because they affect the driver's ability to see the road and other drivers' ability to see into the vehicle. Rear windows have looser limits because they do not affect forward visibility. Understanding where you can tint and how dark you can go will help you avoid a traffic stop or a fix-it ticket.

Key Takeaways

  • Your front windshield can have tint only on the top six inches, and that tint must allow at least 70 percent of light through.
  • Front side windows must allow at least 25 percent of light through, meaning you can use darker tint than on the windshield.
  • Rear windows and rear windshield can be as dark as you want — Texas sets no limit on how dark they can be.
  • Medical exemptions exist for people with light-sensitive skin conditions, but you must carry documentation in your vehicle and register the exemption with the state.
  • A police officer can pull you over for illegal tint, and you may receive a ticket or a fix-it notice requiring you to remove the tint.

Front windshield tint rules in Texas

Your front windshield can have tint, but only in a narrow band at the top. Texas law allows tint on the upper six inches of the windshield only. That tint must allow at least 70 percent of light to pass through, which is a fairly light tint — it will not darken your view much.

The reason for this restriction is safety. The windshield is your primary view of the road, and tint that is too dark can reduce your ability to see pedestrians, other vehicles, and road hazards. The six-inch limit keeps the tint out of your direct line of sight while driving. If your windshield tint extends below six inches or is darker than 70 percent VLT, you are in violation of Texas law.

Front side window tint limits

Your front side windows — the windows next to the driver and front passenger — can be tinted darker than the windshield. Texas requires that front side windows allow at least 25 percent of light through. This means you can use a much darker tint on these windows than on the windshield, but you cannot make them completely opaque.

The 25 percent rule is a balance between privacy and safety. Dark front windows make it harder for other drivers to see into your vehicle, but they still allow enough light through that a police officer can see your face if they approach your car during a traffic stop. If your front side windows are darker than 25 percent VLT, you are violating the law.

Rear window and rear windshield tint — no limit in Texas

Texas places no restriction on how dark you can tint your rear windows or rear windshield. You can make them completely black if you want. The reason is that rear windows do not affect your ability to drive forward, and they do not affect other drivers' safety on the road ahead of you.

Because there is no legal limit on rear tint, this is where many people choose to explore their darkest tint. You can tint the rear side windows and rear windshield as dark as you like without violating Texas law. However, some aftermarket tint shops may refuse to explore extremely dark tint to rear windows for liability reasons, even though it is legal.

Medical exemptions for window tint in Texas

If you have a medical condition that makes you sensitive to sunlight — such as lupus, porphyria, or severe photosensitivity — you may be able to tint your windows darker than the law normally allows. Texas offers a medical exemption for people with documented light-sensitive skin conditions. To use this exemption, you must have a letter from a licensed physician stating that you have a condition requiring protection from sunlight.

You must carry the physician's letter in your vehicle at all times. You should also register the exemption with the Texas Department of Public Safety by submitting the physician's letter and a completed form. Once registered, you will receive documentation that you can show to a police officer if you are stopped. Without this documentation, a police officer has no way to know that your tint is medically necessary, and you can still receive a ticket.

What happens if your tint is illegal

If a police officer determines that your window tint violates Texas law, you can receive a traffic ticket. The violation is a misdemeanor, and the fine can range depending on the officer's discretion and local court policy. In many cases, you will receive a fix-it ticket, which gives you a set amount of time — usually 10 days — to remove the illegal tint and show proof to the court that you have done so.

If you receive a fix-it ticket, you can have the tint removed by a tint shop or by yourself, and then you submit proof of removal to the court. This usually dismisses the ticket. If you do not remove the tint within the time given, the ticket becomes a regular violation with a fine. Some people choose to fight the ticket in court if they believe the tint is within legal limits, but this requires evidence that your tint meets the VLT requirements — which usually means having the tint tested by a professional.

How to measure your window tint darkness

Window tint darkness is measured using a device called a tint meter, which reads the VLT percentage of your windows. Police officers in Texas often carry tint meters, and they use them to determine whether your tint is legal. If you want to know whether your tint is within the legal limit before you have it installed, you can ask the tint shop to measure it with their meter.

Some tint shops will test your windows for free before installation to make sure the tint will be legal. If you already have tint and want to know if it is legal, you can visit a tint shop and ask them to measure it. This can help you decide whether you need to remove it or whether it is within the legal limit. Keep in mind that tint can fade or darken over time, so a tint that was legal when installed may become illegal years later.

Frequently Asked Questions

Can I tint my windshield below the six-inch line?

No. Texas law allows tint only on the top six inches of the windshield. If your tint extends below that line, it is illegal, even if the tint itself is light enough. The six-inch limit is measured from the top of the windshield down.

Is there a penalty for having illegal tint?

Yes. You can receive a traffic ticket, which is a misdemeanor. The fine amount varies, but you may also receive a fix-it ticket giving you time to remove the tint. If you do not remove it within the important date, you face a fine.

Can I have different tint darkness on different windows?

Yes. You can have light tint on your front windows and very dark tint on your rear windows, as long as each window meets its own legal requirement. Many people use this approach to get more privacy in the back while staying legal in front.

Do I need a medical exemption letter with me at all times?

Yes. If you are using a medical exemption to have darker tint than the law allows, you must carry your physician's letter in your vehicle. Without it, a police officer cannot verify that your tint is medically necessary and can still ticket you.

What VLT percentage should I ask for if I want legal tint?

For front side windows, ask for 25 percent VLT or higher. For the windshield top band, ask for 70 percent VLT or higher. For rear windows, you can go as dark as you want. A reputable tint shop will know these limits and can help you choose a legal darkness level.
