Texas Window Tint Law: 25 Percent Front, a Required Label, and No Annual Inspection Since 2025
Texas holds the front side windows to twenty five percent visible light transmission measured with the original glass in place, applies that same twenty five percent to the windshield strip permitted above the AS-1 line, and then stops regulating darkness almost entirely once you are behind the driver. The rear side windows have no darkness limit in the Transportation Code at all. The rear windshield has one only until a pair of outside mirrors is fitted.
The bigger change is not in the percentages. It is that an ordinary Texas car is no longer inspected at all.
| Glass | Texas standard | Note |
|---|---|---|
| Windshield | No film below the AS-1 line; the strip above it must transmit 25 percent or more | Where there is no AS-1 mark the strip stops five inches below the top of the glass |
| Front side windows | 25 percent or more, measured with the original glass | Luminous reflectance 25 percent or less |
| Rear side windows | Not regulated | No darkness limit in the Transportation Code |
| Rear windshield | 25 percent or more, or any darkness with an outside mirror each side | Mirrors must give a view 200 feet to the rear |
| Label | One per vehicle reading Complies with TRC Chapter 547 | Rearmost bottom corner of the driver side window |
The annual safety inspection ended on January 1, 2025
House Bill 3297 removed the safety inspection requirement for non commercial vehicles across the state, effective the first day of 2025. Registration now carries a seven dollar fifty inspection program replacement fee in its place, which the Department of Public Safety was careful to describe as not an increase in the cost of registration. Commercial vehicles are untouched and still need a passing safety inspection in every county. Emissions testing also survives in the metropolitan counties, Harris, Dallas, Tarrant, Travis, Williamson and El Paso among them, with Bexar joining in 2026.
For window film this matters more than any percentage on this page. The annual inspection used to be the one moment in a Texas vehicle year when a licensed station put a meter on the glass and a failing figure had a consequence attached to it. For a private car that moment no longer exists. Nothing in the registration cycle measures tint now, so the only test the film faces is a traffic stop, and the only person with a routine reason to check the numbers beforehand is the shop that installs it.
The label is the installer problem, and it is a thousand dollar problem
Texas requires a label on every vehicle carrying sunscreening material: one per vehicle, stating that it complies with Chapter 547 of the Transportation Code, placed at the rearmost bottom corner of the driver side window. The duty falls on whoever installs the film, and failing it is a misdemeanor carrying a fine of up to one thousand dollars. Ask to see the sticker before you drive off. A shop that skipped it has left a four figure exposure on its own side of the counter and left you nothing to point at when a stop goes sideways.
The medical exemption is a defense, not a permit
This is the detail most summaries state backwards. Texas stopped issuing window tint exemption certificates on the first of January 2019. What the statute provides instead is a defense to prosecution: it is a defense that the defendant, or a passenger in the vehicle at the time of the violation, is required for a medical reason to be shielded from direct sunlight. A defense is raised after a citation, not produced in place of one. A signed statement from a physician or an optometrist buys a strong answer in court and, often enough, discretion at the roadside. It does not buy immunity from the stop itself.
Reflectance, and the part about selling the car
Alongside the transmission figure Texas caps luminous reflectance at twenty five percent or less on the regulated glass, again measured in combination with the original glass. That is the provision mirrored and metallic films run into, and because it is measured separately from darkness a film can pass one test and fail the other. The statute also carves out the seller: offering for sale or selling a vehicle whose windows do not comply is not an offence under the section, which is exactly how a used car arrives wearing film that its new owner inherits along with the keys.
Who is outside the rules
The exceptions run by use rather than by darkness. Law enforcement vehicles sit outside them. So do vehicles used to transport passengers for hire, which covers taxis, limousines and buses. Everything else is measured the same way whether it is a sedan or a three quarter ton truck, because Texas does not lean on the multipurpose passenger vehicle carve out that several neighboring states use to loosen the glass behind the driver.
Leaving Texas changes the calculation faster than most drivers expect, and the bordering-jurisdiction table further up this page holds the live figures. Oklahoma and Arkansas match Texas at twenty five percent up front, and Louisiana now does too after lowering its front limit in 2025, so the front glass usually travels. The back does not: all three regulate the rear side windows that Texas leaves alone, and New Mexico runs the darkest front side allowance in the country. A build that is legal on a Houston commute is not automatically legal an hour past the line.
