Window Tint Laws:
Texas & Every State
Every state regulates tint by VLT — Visible Light Transmission, the percentage of light your glass must still let through. This guide breaks down the Texas rules we install to every day at our Houston studio, then puts all 50 states + DC in one table.
Educational guide, not legal advice. Tint laws change — always confirm current rules with your state's DMV or statutes before installing.
How Tint Laws Actually Work
Four concepts explain every tint law in America. Learn these and the state table below reads itself.
Visible Light Transmission
The percentage of visible light that makes it through your glass. Higher VLT = lighter tint. A "70%" law is strict (barely any darkening allowed); a "25%" law allows a visibly dark window. "Any" means no darkness limit at all.
The stack is what's measured
Police meters read the combined VLT of film plus factory glass — and factory glass alone usually passes only 70–80% of light. Install "35% film" on 75% glass and the meter reads roughly 26%. Good shops quote the net number, not the box label.
The windshield line
Most states only allow tint on the windshield above the AS-1 line — the marking near the top edge of the glass — or above the top few inches. Below that, the windshield stays clear in almost every state.
Reflectivity limits
Separate from darkness, many states cap how mirrored a film can be. Texas caps side-window reflectance at 25%. Chrome-mirror films are illegal in most of the country regardless of VLT.
Zones, not one number
Every law splits the car into zones: windshield, front side windows, back side windows, rear window. Front sides are almost always the strictest — that's the number to know in your state.

What Each Tint % Looks Like
Same car, six shades — lower VLT means darker glass. In Texas, 25% or more is street-legal on the front side windows; 20% and darker lives behind the driver.

Texas Tint Law, Zone by Zone
Texas is friendlier than most states — but the front windows and windshield have hard limits, and they're enforced. Here's the law we build every Houston install around.
Front side windows
Must let 25% or more of the light through — film and factory glass combined — with reflectance of 25% or less.
Windshield
Untinted below the AS-1 line. Above it (or the top 5 inches, whichever is closer to the top), a strip is allowed at 25%+ VLT, ≤25% reflectance — and never red, amber or blue.
Back side windows
No darkness limit behind the driver — 20%, 5%, limo, your call.
Rear window
Any darkness if the car has outside mirrors on both sides. No mirrors on both sides? Then the rear glass needs 25%+ VLT.
Illegal tint is a misdemeanor in Texas with a fine of up to $200 under the default traffic-offense penalty — and a shop that installs film without the required compliance label can be fined up to $1,000. Texas ended annual safety inspections for regular passenger cars on January 1, 2025 (Houston's Harris County still runs an emissions check, which doesn't look at tint), so enforcement now happens where it always mattered most: the traffic stop, where the officer's meter reading — with a 3% grace variance — decides the ticket. We keep every Spec'd Studios install street-legal by default and confirm the net VLT on your exact glass before film goes on.

Rows marked ✓ are checked directly against the state's statute or DMV text; every other row is cross-checked across two independent 2025–2026 industry digests (compiled July 2026). Laws change and enforcement varies — treat this as a starting point and confirm with your state's DMV before installing. Values are for passenger cars; several states allow darker rear zones on SUVs, trucks and vans.
Tint that was legal in your old state has to meet Texas rules once your car is registered here. The usual fix for out-of-state cars: lighten the front sides to 25%+ and keep everything behind the driver as-is. We handle front-window swaps constantly at our EaDo studio — get a quote →. Not moving — just not local? We travel nationwide for wraps, PPF and tint: tell us where the car lives and we'll make a plan.
Medical Exemptions
Most states — Texas included — allow darker-than-normal tint for drivers with light-sensitive medical conditions. Here's how it works in Texas.
A medical need
Conditions like lupus, melanoma risk or photosensitivity disorders that make sun exposure through glass a genuine medical problem.
A signed statement
Texas requires a written statement from a licensed physician or optometrist that darker tint is medically necessary for a regular driver or passenger of the vehicle.
Keep it in the car
There's no state sticker — the signed statement is the exemption, so it lives in the glovebox and gets presented at a stop. It allows darker front side windows and a darker windshield band only; nothing below the AS-1 line, ever.
Other states run exemptions differently — some issue DMV permits or stickers, and a handful don't offer exemptions at all. Check your state's DMV page (linked rules in the table above) before going darker on medical grounds.
Tint Law FAQ
What's the darkest legal tint in Texas?+
On the front side windows: 25% VLT — the glass must still pass at least 25% of visible light. Behind the driver it's a different story: back side windows can be any darkness, and the rear window can too as long as the car has outside mirrors on both sides. That's why "limo back, legal front" is the standard Texas look.
Is 20% tint legal in Texas?+
On the back side windows and rear window (with dual side mirrors): yes. On the front side windows: no — 20% is below the 25% VLT minimum and is ticketable. If you want the darkest legal front, we install film that nets out just above 25% on your actual glass.
Can police pull you over just for tint?+
In Texas, tint that appears darker than the legal limit can be the reason for a traffic stop — it's an equipment violation on its own, no other offense needed. Officers carry VLT meters, and the meter reading through film + glass is what counts — Texas allows a 3% variance on the reading, and that's it.
How much is a tint ticket in Texas?+
Illegal tint is a misdemeanor with a fine of up to $200 under Texas's default traffic-offense penalty — and a shop that installs film without the required compliance label can be fined up to $1,000. The bigger cost is being ordered to strip and redo the film. Doing it legal the first time is cheaper than doing it twice.
Does factory glass tint count toward the limit?+
Yes. The law regulates the light that passes through the window, so meters measure film and glass together. Factory glass usually reads 70–80% by itself, which is why 35%-labeled film can meter in the high 20s once installed. We measure the net number on your car before and after.
Are windshield tint strips legal?+
In Texas, yes — above the AS-1 line (or the top 5 inches), non-reflective and 25%+ VLT. Below the line the windshield stays untinted — but Texas DPS explicitly allows clear, untinted UV film across the full windshield, no exemption needed. That's the street-legal way to kill windshield heat, and we cover it in the windshield protection guide.
I'm moving to Texas — do I have to change my tint?+
If your front side windows are darker than 25% VLT, yes — once the car is Texas-registered, Texas rules apply, and out-of-state paperwork won't beat a meter reading. The usual fix is re-doing just the front two windows and leaving the rest alone.
Do tint laws apply to Teslas and EVs differently?+
No — same zones, same numbers. The wrinkle is that EVs carry more glass (roofs, huge windshields), so more of the car benefits from legal film. We wrote a full Tesla & EV tint guide for exactly that.
Do you only install in Houston?+
Home base is our EaDo studio in Houston — and we travel nationwide for the right project. Wraps, PPF and tint on location for collections, fleets and builds anywhere in the US: tell us the city and the car and we'll make a plan. Out-of-state cars are welcome at the studio too — and we'll tint to your home state's numbers, not just Texas's.
Tint It Legal. Tint It Once.
Every Spec'd Studios install is metered against the law before the film goes on — darkest legal front, any look you want behind. Based in Houston, traveling nationwide. Tell us what you drive and we'll quote it, usually the same day.
