Texas drivers use window tint to block heat and protect their privacy. Tinted windows can also reduce glare and shield the skin from UV rays. On hot roads, tint brings real comfort.
But Texas law does not allow all types of tint. The rules limit how dark each window can be. These limits help officers see inside the car. They also make sure drivers can see clearly at night.
The state uses a rule called Visible Light Transmission, or VLT. This shows how much light passes through the glass. A lower number means the tint is darker.
This guide explains Texas tint laws for 2025. It covers legal limits, banned colors, and medical rules. Read this before you tint your car or drive in Texas. You will avoid fines and stay within the law.
What Is VLT and Why It Matters
Texas tint law uses a rule called Visible Light Transmission, or VLT. This tells how much light passes through your window and the tint. A high number means more light comes in. A low number means the tint is darker.
If a window must have 25% VLT, it must let in at least 25% of visible light. You cannot use a film that blocks more than 75% of the light on that glass.
Each window on your car follows a different rule. The law sets separate VLT limits for front, back, and rear windows. You must follow the rule for each part.

Legal Tint for Front Side Windows
In Texas, the front side windows must allow at least 25% VLT. This rule means the window should let in a quarter of the light. You can’t use darker films on these windows. If you break this rule, you may get a fine.
Also, the tint must not reflect more than 25% of light. Highly reflective films are not allowed. Some tint shops offer mirror-like tints. These are often illegal in Texas. Stick to non-reflective or lightly reflective films.
Legal Tint for Back Side Windows
Texas allows any level of tint on back side windows for most passenger vehicles. You can use darker tint or even full black-out film. Still, keep reflectivity under control. Reflective film cannot go beyond 25%.
For SUVs and vans, these back windows often come pre-tinted from the factory. You may still add more film, as long as it stays within state rules.
Legal Tint for Rear Window
Texas law allows dark tint on the rear window if your car has side mirrors on both sides. These mirrors must give a clear view behind the car.
If your car has no side mirrors, the rear window must let in at least 25% of visible light. A tint that blocks more than 75% would break the rule.
This law helps police see inside and keeps driving safe. Before you tint the rear window, check that both mirrors work and meet the law.
Windshield Tint Rules
Texas allows a strip of tint at the top of the front windshield. This is called the AS-1 line. The tint strip must not go below this line, which sits about 5 inches from the top of the windshield.
The tint must be non-reflective and must not block visibility. Full windshield tint is not allowed. Only factory-installed sun filters or clear UV films are legal. Anything darker will break the law and lead to fines.
Reflectivity Rules
Texas also limits how reflective your tint can be. Reflective tint can cause glare and blind other drivers. It may also stop law enforcement from seeing inside your vehicle.
Both front and back side windows must not reflect more than 25% of light. This rule applies to all cars, no matter the window’s size or shape. Avoid mirror-style or metallic films unless they meet this reflectivity limit.
Color Restrictions
Texas does not allow red, blue, or amber tint on any car windows. These colors may look like lights used on police or emergency vehicles.
Stick to basic colors such as gray, black, or green. These shades are safe and legal.
Some tint shops may offer bright colors to change your car’s look. Ask before you buy. If the color breaks state law, you could face a fine or a traffic stop.
Medical Exemptions
Some drivers have health conditions that require extra sun protection. Texas allows medical tint exemptions in such cases. The driver must carry a signed letter or prescription from a licensed doctor or optometrist.
With an exemption, you may install darker tint on front windows or even the windshield. Still, you must keep the medical proof inside the car. If stopped, you must show this to the officer.
Apply for the exemption through the Texas Department of Public Safety (DPS). Your paperwork must match your vehicle’s license plate and registration.
Tint Sticker Requirement
Texas law also asks for a sticker on each tinted window. This sticker must be placed between the tint film and the glass. It shows that the tint meets state standards.
The installer should provide this sticker after completing the job. If your tint has no sticker, police may question its legality-even if it follows the rules.
Never remove these stickers unless you remove the tint. They serve as proof that your vehicle is in compliance.
Penalties for Illegal Tint
If your window tint breaks Texas law, you may face:
- A fine of up to $200
- A fix-it ticket that requires you to remove or replace the tint
- Trouble during vehicle inspection or renewal
Repeat offenses can lead to higher fines and even license points. The best way to avoid trouble is to check the VLT rating before applying new film. Ask the tint shop for a certificate of compliance.
Final Thoughts
Texas tint laws aim to protect both drivers and the public. They allow comfort from sun and heat but still keep your car safe and legal.

Before you tint your car, speak with a licensed installer. They will know what meets Texas law. Ask for proof that the film is legal.
