Thinking about tinting your car windows in Granbury? Before you do, you need to know the rules. Texas window tint laws are specific about how dark your windows can be, and getting it wrong can mean fines, failed inspections, and the hassle of removing your tint.
Here’s everything you need to know about legal window tint in Texas for 2026.
How Texas Measures Window Tint
Texas uses VLT (Visible Light Transmission) to measure window tint darkness. VLT is the percentage of light that passes through your window. The lower the number, the darker the tint.
For example:
- 70% VLT = Very light, almost clear
- 35% VLT = Medium tint
- 20% VLT = Dark tint
- 5% VLT = “Limo tint,” nearly blacked out
When measuring VLT, Texas looks at the combined darkness of your tint film AND your factory glass together, not just the film alone. This matters because most factory windows already block some light.
What’s the Legal Tint Limit for Each Window?
Here’s what’s legal in Texas for all vehicle types (cars, trucks, SUVs, and vans):
Windshield
- Tint allowed only above the AS-1 line (or top 5 inches if no AS-1 line)
- Must allow more than 25% light transmission
- Must be less than 25% reflective
- Clear UV film is allowed on the entire windshield without restrictions
Front Side Windows (Driver & Passenger)
- Must allow more than 25% of light in (25% VLT or higher)
- Must be less than 25% reflective
Back Side Windows
- Any darkness allowed
- No VLT restrictions
Rear Window
- Any darkness allowed IF you have dual side mirrors
- Without dual side mirrors: must allow more than 25% light in
Note: These laws apply to cars, trucks, and SUVs. If you’re looking to tint your RV, there are different considerations since those aren’t subject to Texas vehicle inspection requirements.
What Does 25% Tint Actually Look Like?
A lot of people ask us what 25% tint looks like in real life. At 25% VLT, you can still see into the vehicle from outside during the day, but it provides solid privacy at night. It’s dark enough to reduce glare and block heat, but light enough to keep you legal.
For reference, factory “privacy glass” on most trucks and SUVs is usually around 15-20% VLT on the rear windows, which is legal in Texas for back windows.

Other Rules You Need to Know
Beyond the darkness limits, Texas has a few other requirements:
Restricted Colors: Red, blue, and amber tints are not allowed on any window. These colors can be confused with emergency vehicle lights.
Certification Sticker Required: Texas law requires a sticker between the tint film and glass on the driver’s side window. This sticker identifies the installer and confirms the tint meets state requirements. At Granbury Window Tint, we include this sticker with every installation.
Dual Side Mirrors: If your rear window is tinted darker than 25%, your vehicle must have side mirrors on both sides.
Film Certification: All window tint film sold in Texas must be certified by the manufacturer. We only use certified films from trusted brands like GeoShield to ensure your tint is legal and high-quality.
What Happens If You Get Caught with Illegal Tint?
Getting caught with illegal tint can cost you:
- First offense: $20-$25 fine
- Repeat offenses: Up to $275 or more
- Failed inspection: Your vehicle won’t pass the annual Texas safety inspection with illegal front window tint
- Fix-it ticket: You may be required to remove the tint and prove compliance
The bigger hassle is failing your inspection. In Texas, you can’t renew your registration without passing inspection, so illegal tint on your front windows will catch up with you eventually.
Can You Get a Medical Exemption for Darker Tint?
Yes. Texas allows medical exemptions for drivers who need a darker tint due to health conditions. Qualifying conditions include:
- Lupus
- Albinism
- Photosensitivity disorders
- Certain skin conditions or skin cancer
- Xeroderma pigmentosum
To get an exemption, you need a signed statement from a licensed physician or optometrist explaining that a darker tint is medically necessary. You’ll need to keep this document in your vehicle and present it during inspections or traffic stops.
Note: As of January 2019, Texas DPS no longer issues Window Tint Exemption Certificates. The doctor’s statement alone serves as your documentation.
How to Stay Legal and Still Get the Tint You Want
Here’s the good news: you can still get great heat rejection, UV protection, and a sharp look while staying within Texas law.
Ceramic tint is a game-changer for Texas drivers. Ceramic films block significantly more heat than traditional dyed films at the same darkness level. So you can run a legal 25% VLT on your front windows and still get serious heat rejection, sometimes blocking 50-60% of solar heat.
We recommend ceramic tint for anyone who wants maximum performance within legal limits. It costs a bit more upfront, but the comfort difference in Texas summers is worth every penny.
Go dark on the back. Since Texas allows any darkness on rear and back side windows, many customers choose 5-20% VLT on the back half of their vehicle for maximum privacy, then 25-30% on the front to stay legal.
The same heat-blocking benefits apply to home window tinting, too, if you’re tired of hot rooms and faded furniture. Residential tint uses similar technology to keep your house comfortable.
