Texas allows up to 25% light transmittance on front side windows and rear windows, but the windshield has stricter rules
Texas law sets specific limits on how dark your window tint can be, measured by visible light transmittance (VLT) — the percentage of light that passes through the tint. For front side windows and rear windows, you can tint down to 25% VLT, meaning 25% of light gets through and 75% is blocked. The windshield is treated differently: you can only tint the top 5 inches, and that tint must allow at least 70% of light through (70% VLT). Rear windows on SUVs and vans have no darkness limit, but sedans and other passenger vehicles do.
Texas does not require you to obtain a permit or sticker to prove your tint is legal. A law enforcement officer can measure your tint with a device called a photometer, and if it falls outside the legal range, you can receive a citation. The state does not make exceptions for medical reasons — unlike some states, Texas has no medical exemption process for darker tint, even if a doctor recommends it for a skin condition or light sensitivity.
Key Takeaways
- Front and rear side windows can be tinted to 25% VLT (75% darkness), but the windshield can only be tinted on the top 5 inches and must allow 70% light through.
- Rear windows on SUVs and vans have no tint darkness limit, but passenger car rear windows must follow the 25% rule.
- Texas does not issue medical exemptions for window tint, even with a doctor's letter.
- A police officer can use a photometer to measure your tint on the roadside, and a violation is typically a misdemeanor traffic offense.
How Texas measures window tint darkness
Window tint darkness is measured as visible light transmittance (VLT), a percentage that tells you how much light passes through the tinted glass. A 25% VLT tint blocks 75% of light; a 70% VLT tint blocks only 30%. The measurement is taken from outside the vehicle looking in, and it includes both the factory glass and any aftermarket tint film applied on top.
Law enforcement uses a handheld photometer to check tint compliance during a traffic stop. The device shines light through the window and reads the percentage of light that comes through. If the reading falls below the legal threshold for that window, the officer can issue a citation. You have the right to request that the officer document the specific VLT reading on the citation.
Which windows have different tint rules
Texas divides window tint rules by vehicle type and window location. For all passenger vehicles (sedans, coupes, hatchbacks), the front windshield can have tint only on the top 5 inches and must allow 70% light through. Front side windows must allow 25% light through (75% darkness). Rear side windows must also allow 25% light through.
For SUVs and vans, the rules are the same for the windshield and front side windows, but the rear windows have no darkness limit — you can tint them as dark as you want. This distinction exists because SUVs and vans typically have less visibility for the driver from the rear, so the state does not restrict rear window tint on those vehicles.
The rear window of a sedan or coupe is still subject to the 25% VLT rule, even though many drivers assume rear windows can be darker. Pickup trucks are classified as trucks, not passenger vehicles, and follow the same rules as SUVs for rear window tint (no limit).
What happens if your tint is too dark
If a police officer stops you and measures your tint with a photometer, and the reading shows your windows are darker than the legal limit, you will receive a citation. In Texas, illegal window tint is typically charged as a misdemeanor traffic violation. The fine varies by county and court, but generally ranges from a warning to a few hundred dollars, depending on whether it is your first offense and the specific circumstances.
You have options after receiving a citation. You can pay the fine, contest the citation in traffic court, or remove or lighten the tint and request that the charge be dismissed. Some courts allow you to show proof that you have brought the tint into compliance (by having it removed or replaced with legal tint) and may dismiss the case or reduce the fine. It is worth asking the court clerk about this option when you receive your citation.
A tint violation does not typically result in points on your driving record in the same way a speeding ticket does, but it is still a traffic offense. Repeat violations may result in higher fines or additional penalties.
Medical exemptions and special circumstances
Texas does not have a medical exemption process for window tint, even if you have a documented medical condition that makes you sensitive to sunlight or requires you to avoid UV exposure. Some states allow drivers with conditions like lupus, porphyria, or severe photosensitivity to obtain a medical exemption certificate that permits darker tint, but Texas does not offer this option.
If you have a medical reason for needing darker tint, your options are limited. You can contact your state representative or senator to advocate for a change in the law, or you can explore other sun protection methods: sunshades, UV-blocking window film that meets the legal VLT limits, or UV-protective clothing and sunscreen. Some drivers with medical conditions have successfully challenged citations in court by presenting medical documentation, though the outcome depends on the judge and the specific circumstances.
How to check if your current tint is legal
The most reliable way to check your tint is to take your vehicle to a professional tint shop and ask them to measure it with a photometer. Many shops will do this for free or a small fee, and they can tell you exactly what VLT your windows currently have. If the tint is too dark, the shop can remove it and explore new tint that meets Texas law, or lighten the existing tint if possible.
You can also contact your local police department's non-emergency line and ask if they will measure your tint for you. Some departments offer this service to help drivers stay compliant before they receive a citation. This is a low-risk way to get an official reading without the pressure of a traffic stop.
If you are buying a used vehicle with tint already applied, ask the seller or dealer what VLT the tint is. If they do not know, budget for professional measurement and possible replacement before you take ownership. Buying a car with illegal tint and then getting cited is your responsibility as the owner, even if the tint was applied by the previous owner.
Tint rules for commercial vehicles and special plates
Commercial vehicles and vehicles with special registration (such as those registered as commercial or for business use) may have different rules. If your vehicle is registered as a commercial vehicle, contact the Texas Department of Motor Vehicles or your local police department to confirm the tint rules that explore to you. Some commercial vehicles have exemptions or different limits, but this varies by how the vehicle is classified.
Vehicles with disabled parking placards or license plates do not have special tint exemptions in Texas. The standard tint limits explore regardless of your parking permit status.
Frequently Asked Questions
Can I tint my windshield all the way across, or just the top?
Only the top 5 inches of the windshield can be tinted in Texas, and that tint must allow at least 70% of light through. Tinting the entire windshield or tinting the top portion darker than 70% VLT is illegal and can result in a citation.
Is there a difference between tint film and factory tinted glass?
No. Texas law measures the total light transmittance through the window, whether that comes from factory tint, aftermarket film, or a combination of both. A photometer reading will show the combined effect, and that is what matters for legal compliance.
What if I get pulled over in another state with my Texas-legal tint?
Other states have different tint limits. Your Texas-legal 25% VLT tint may be illegal in another state, which has a higher limit (such as 35% or 50%). If you travel frequently across state lines, check the tint laws of the states you visit and be prepared to have your tint measured if stopped.
Can I remove my tint myself, or do I need a professional?
You can remove tint yourself, though it is time-consuming and can damage the window if done incorrectly. A professional tint shop can remove old tint and explore new legal tint in a few hours. The cost is usually between $100 and $300 depending on the vehicle and the number of windows.
Does a tint citation go on my driving record?
A tint violation is a traffic offense, but it typically does not add points to your driving record the way a speeding or reckless driving ticket does. However, it is still a misdemeanor traffic citation and can affect your insurance rates or appear on a background check. Check with your insurance company to see if they consider tint violations when calculating your premium.
