Texas Window Tint Law: Limits, Exemptions, and Fines

Texas window tint law sets a single key number for the parts of the car an officer cares about: front side windows and the windshield strip must allow at least 25% of light through (25% VLT) and reflect no more than 25% of light back.¹ Rear side windows have no darkness limit, and the rear windshield is unrestricted as long as the vehicle has an outside mirror on each side. Everything else in the statute is detail around those rules.

Front Side Windows

The driver’s window and front passenger window are where almost every tint ticket is written. Under Texas Transportation Code Section 547.613, any sunscreening device on these two windows must allow at least 25% of light through and reflect no more than 25% of light back.¹

The measurement that matters is the film and the glass together, not the film on its own. Factory glass already blocks some light, so a film rated at exactly 25% will measure below the legal threshold once it’s on the window. A reputable installer accounts for this, but confirm it before you pay. There is no color restriction on front side windows, but the 25% reflectance cap rules out mirror-finish films.

Rear Side Windows and the Rear Windshield

Everything behind the driver’s seat is exempt from VLT and reflectance limits.¹ You can run privacy film as dark as you want on rear side windows, including fully opaque film, on sedans, SUVs, and trucks.

The rear windshield is exempt only if the vehicle has an outside mirror on each side that gives the driver a view at least 200 feet to the rear.¹ Nearly every modern passenger vehicle meets that condition, so in practice the rear window has no darkness limit either.

Windshield Strip and the AS-1 Line

The windshield gets the strictest treatment. Tint film is only allowed on the strip above the manufacturer’s AS-1 line, or the top five inches of the windshield, whichever is closer to the top.¹ That strip has to meet three conditions: at least 25% VLT with the glass, no more than 25% reflectance, and no red, blue, or amber coloring. Those colors are reserved for emergency vehicles and could be confused with traffic signals.

Below that strip, the statute prohibits any material that alters color or reduces light transmission. A truly clear UV film that doesn’t change color or dim the glass would not trigger the ban, but the statute does not carve out an explicit exemption. Officers won’t give you the benefit of the doubt during a stop, so confirm any full-windshield film is measurably clear before installation.

Medical Exemption for Darker Tint

If a medical condition makes extra sun protection necessary, Texas allows darker-than-legal tint on the two front side windows and the upper windshield strip. You need a signed statement from a licensed physician or optometrist that identifies you and states that sunscreening is necessary for your health.² The exemption does not cover the main viewing area of the windshield below the AS-1 line or five-inch mark.³

The statute doesn’t list qualifying diagnoses. The physician’s judgment that sun shielding is medically necessary is what matters, and conditions commonly cited include lupus, melanoma and other skin cancers, albinism, xeroderma pigmentosum, and photosensitivity from certain medications. Keep the signed statement in the vehicle. Without it on hand, an officer has no way to verify the exemption and will write the ticket.

Fines and How to Get the Ticket Dismissed

Driving with illegal tint is a misdemeanor under Section 547.613. Fines for equipment violations typically run up to $200, with court costs on top. A separate penalty of up to $1,000 per offense applies to professional installers who fail to place the required compliance label.¹ That $1,000 figure sometimes gets quoted as the driver’s fine; the statute reserves it for installers.

There is a practical way out. Under Section 547.004, a court may dismiss an equipment violation if you fix the problem before your first court appearance and pay a reimbursement fee of no more than $10.⁴ Removing the non-compliant film, or having it replaced with a legal one, and bringing proof to court is the cheapest resolution. The dismissal option does not apply to commercial motor vehicles.

Enforcement After the End of Safety Inspections

Texas eliminated its annual vehicle safety inspection program for non-commercial vehicles on January 1, 2025.⁵ A $7.50 inspection replacement fee is now collected at registration, and tint compliance is enforced through traffic stops. You won’t find out there’s a problem at an annual appointment. The first sign is a patrol officer’s lights in your mirror.

The Compliance Label

Texas requires professional installers to place a compliance label between the film and the glass. The Department of Public Safety interprets this as one label per vehicle, at the rearmost bottom corner of the driver’s side window, reading “Complies with TRC Chapter 547” or equivalent.² Missing the label isn’t automatically illegal, but it removes the quick visual signal that tells an officer the tint is within limits, which makes a stop and citation more likely.

Out-of-State Vehicles and Commercial Trucks

Vehicles not registered in Texas are explicitly exempt from the state’s tint law.¹ Driving through on plates from another state, Texas cannot cite you for tint that is legal where the vehicle is registered. Once you register in Texas, the exemption ends and the 25% VLT standard applies.

Commercial motor vehicles follow a stricter federal standard. Under 49 CFR 393.60, the windshield and the windows immediately left and right of the driver on a commercial vehicle must allow at least 70% light transmission.⁶ Other windows on the commercial vehicle have no federal tint restriction, and the Section 547.004 fix-it dismissal is not available for commercial drivers.
