Texas allows 5 percent tint on rear and back side windows, but not on the front windshield or front side windows
In Texas, the legal limit for window tint darkness is measured in Visible Light Transmittance (VLT) — the percentage of light that passes through the tinted glass. A 5 percent tint blocks 95 percent of light, making it extremely dark. You can use 5 percent tint on your rear window and back side windows without breaking the law. You cannot use it on your front windshield or front side windows, where Texas has stricter rules.
The reason for these different limits is visibility and safety. Police need to see into vehicles during traffic stops, and other drivers need to see pedestrians and oncoming traffic. Front windows have stricter limits because they affect your own ability to see the road and other drivers' ability to see you.
Key Takeaways
- Texas allows 5 percent tint on rear windows and back side windows, but prohibits it on front windows.
- Front side windows must allow at least 25 percent light through; the front windshield must allow at least 70 percent light through above the manufacturer's AS-1 line.
- Window tint darkness is measured in VLT (Visible Light Transmittance), and you can ask a tint shop to measure your windows before installation.
- If your tint is too dark for your window location, you can be stopped by police and issued a citation; the fine varies by county but typically ranges from $100 to $200.
- Medical exemptions exist for people with light-sensitive conditions, but you must carry documentation and display a special certificate on your vehicle.
The legal tint limits for each window in Texas
Texas law sets different VLT limits depending on which windows you are tinting. The rear window and back side windows (behind the driver and front passenger) can be as dark as you want — including 5 percent tint. The front side windows must allow at least 25 percent of light through. The front windshield is the most restricted: you can only tint the area below the manufacturer's AS-1 line (usually a few inches from the top), and that tinted section must allow at least 70 percent of light through.
The AS-1 line is a marking on the windshield itself — it is the boundary between the part the manufacturer designed for tinting and the part that must stay clear. You cannot tint above this line, even with a lighter tint percentage. If you are unsure where your AS-1 line is, a professional tint shop can identify it for you.
How to measure tint darkness before installation
If you are considering tinting your windows, you can have the darkness measured before the work is done. Professional tint shops use a device called a tint meter to measure VLT. The meter shines light through the glass and displays the percentage of light that passes through. This takes less than a minute per window and costs nothing if you are planning to have the shop do the work.
You can also ask the tint shop to show you sample tints at different percentages so you can see what 5 percent, 20 percent, and 25 percent actually look like. This is especially useful for front side windows, where the legal limit of 25 percent is darker than many people expect but still allows reasonable visibility. Many shops keep sample windows on display for this reason.
What happens if your tint is too dark
If you are stopped by police and your tint is darker than the legal limit for that window, you will be issued a citation. The offense is typically classified as a minor traffic violation. Fines vary by county but generally range from $100 to $200. You will not face jail time for a first offense, but the citation will appear on your driving record.
You have the option to remove or lighten the tint and show proof to the court, which often results in the citation being dismissed or reduced. Some courts allow you to submit a photo of your vehicle after the tint is removed rather than appearing in person. Check with the specific court listed on your citation for their procedure.
Medical exemptions for light-sensitive conditions
Texas allows a medical exemption for people with conditions that make them sensitive to light, such as lupus, porphyria, or severe photophobia. If you have a may have access to condition, you can tint your front side windows darker than the standard 25 percent limit. You must obtain a certificate from the Texas Department of Public Safety (DPS) and display it on your vehicle.
To get a medical exemption certificate, you need a signed statement from a licensed physician confirming that you have a light-sensitive condition and that tinted windows are medically necessary. You submit this letter along with your vehicle registration to your local DPS office. The certificate is valid for four years and must be renewed after that. Even with a medical exemption, you still cannot tint your front windshield above the AS-1 line, and the tint on front side windows must still allow at least 35 percent light through (not as dark as the rear windows).
Tint shops and installation in Texas
Most professional window tint shops in Texas are familiar with state law and will not install tint that exceeds the legal limits for each window. When you call or visit a shop, tell them you want tint that complies with Texas law, and they will recommend the appropriate darkness for each window. Reputable shops will measure your windows and confirm the VLT before installation.
If you choose to tint your windows yourself using aftermarket film, you are responsible for ensuring the final result meets Texas law. DIY tinting is difficult to do evenly and to the exact legal limit, and if the tint is too dark, you will face the same citation as if a shop had installed it. Many people find professional installation worth the cost partly because the shop assumes responsibility for compliance.
Frequently Asked Questions
Can I have 5 percent tint on my front side windows?
No. Front side windows must allow at least 25 percent of light through in Texas. You can only use 5 percent tint on your rear window and back side windows. If your front side windows are tinted to 5 percent, you can be cited.
What if I have a medical exemption — can I use 5 percent on front windows?
No. Even with a medical exemption, your front side windows must allow at least 35 percent light through. The exemption allows you to go darker than the standard 25 percent limit, but not as dark as the rear windows. Rear windows can still be 5 percent even without an exemption.
Is there a grace period for tint that is slightly too dark?
No. Texas law does not include a tolerance range. If your tint measures darker than the legal limit for that window, you can be cited. However, some officers may use discretion, and some courts are lenient on first offenses if you remove the tint promptly.
Do I need to remove tint if I move to Texas from another state?
If your tint was legal in your previous state but is too dark for Texas, you should have it removed or lightened before driving regularly in Texas. Texas police enforce the state tint law, and you can be cited even if the tint was legal where you installed it.
Can I tint my windshield above the AS-1 line?
No. Texas law prohibits tinting above the AS-1 line on any vehicle, even with a medical exemption. The AS-1 line is the manufacturer's safety boundary, and the area above it must remain clear for visibility and airbag deployment.
