In Texas, the front side windows must allow at least 25 percent VLT. The windshield can only be tinted along the top 5 inches (or down to the AS-1 line, whichever is lower). Rear side windows and the back glass can be any darkness. That is the law in plain English.
Most of what you have heard from a friend, a guy at a car meet, or another shop is wrong about at least one of those rules. So here it is, in detail, from a shop in Wylie that has to live with these laws every working day.
The actual statute
Texas Transportation Code Section 547.613 is the law that governs window tint on passenger vehicles. The numbers below come straight from it.
Windshield
You can tint a strip across the top of the windshield. The strip can be no wider than 5 inches measured down from the top of the glass, or it must stop at the AS-1 line marked by the manufacturer, whichever results in a smaller strip.
Inside that strip, the tint can be any darkness you want. It is the only place on the windshield you can tint.
The rest of the windshield must remain free of tint film. Factory tint in the glass itself is fine. Aftermarket film below the strip is not.
Front side windows
The driver and front passenger windows must allow at least 25 percent VLT. This is where most owners run into trouble.
A 25 percent VLT means 25 percent of visible light gets through the window. Lower numbers mean darker tint. Texas does not allow you to go below 25.
Not 20. Not 15. Not 5. The legal floor is 25 percent VLT on the fronts.
We will not install darker than legal. If a shop offers to put 5 percent on your fronts, walk away. They are setting you up for a ticket.
Rear side windows
No VLT restriction. You can tint the rear side windows as dark as you want, including 5 percent (limo tint).
Rear windshield
Same as the rear side windows. No VLT restriction. As dark as you want.
This applies to passenger cars and light trucks with outside mirrors on both sides, which is essentially every modern vehicle.
Reflectivity
No window can have more than 25 percent reflectivity. Reflective or mirrored films above that level are illegal in Texas. We use quality films from XPEL, Llumar, 3M, and Suntek that meet the reflectivity rules without issue.
Common myths we hear weekly
“20 percent on the fronts is fine because my buddy in Plano has it.” Your buddy is breaking the law. He just has not been pulled over for it yet.
“You can tint the whole windshield as long as it is light.” No. The strip rule is the strip rule. Anything below the AS-1 line or 5 inch mark must be untinted.
“Cops in Wylie do not pull people over for tint.” They absolutely do, and so do troopers anywhere else in the state. It is also a common reason for being asked to roll the window down at a stop.
“Limo tint on the back is illegal.” Not in Texas. The back glass and rear side windows can be as dark as you want.
What happens if you get pulled over
Illegal tint in Texas is a Class C misdemeanor. Fine up to about $200, plus you may be required to remove the illegal film and provide proof of compliance.
The bigger cost is sometimes the secondary issue. A tint stop can become a longer stop. If the officer sees a reason to look closer at anything else, they will. Easier to be legal in the first place.
Medical exemption
Texas allows a medical exemption for drivers or passengers with a verified medical condition that requires reduced sun exposure. If you qualify, you get a signed exemption certificate from a licensed medical practitioner and you keep a copy in the vehicle.
With the exemption, you can install darker tint on the front side windows than the standard 25 percent VLT minimum. The exemption does not waive the windshield strip rule.
What we install for legal Texas tint
For the fronts, we usually go 35 percent VLT in a quality ceramic. That gives you significant heat and UV reduction, looks darker than factory, and stays on the right side of the legal line with margin.
For owners who want as dark as legal, we install at 25 percent VLT on the fronts. We test every install with a tint meter to confirm we are inside the law.
For the rears, you tell us. 35, 20, 5, your call. We commonly install 20 percent for a clean uniform look from the outside, or 5 percent if you want full privacy on the back glass.
We install Llumar IRX, 3M Crystalline, and Suntek carbon depending on the budget and the performance you want. All of them are available in Texas-legal VLT ranges.
Pricing for a legal install
Carbon tint full vehicle runs $250 to $375 in our shop. Ceramic full vehicle runs $450 to $700. Headlight tint runs $100 to $200 per pair.
Send us your year, make, and model and what VLT you want for fronts and rears, and we will give you a real quote.
The simple version
Stay at 25 percent VLT or higher on the front side windows. Tint only the top strip of the windshield. Go as dark as you want on the rears. Use a quality film. Get it installed by a shop that owns a tint meter and uses it.
That is how you stay legal in Texas and still get the tint you actually want.
