Texas Window Tint Laws

Under Texas law, front side windows must allow at least 25 percent visible light transmission (VLT). Rear side windows and the rear windshield can be any darkness, as long as the vehicle has dual outside mirrors. Windshield tint is limited to a strip above the manufacturer’s AS-1 line or the top five inches, also at 25 percent VLT minimum. These state of Texas tint laws apply equally to sedans, trucks, SUVs, and vans.

What Is the Legal Tint Limit in Texas by Window?

VLT measures how much visible light passes through your window glass and tint film combined. A lower VLT percentage means a darker tint. Here is how Texas Transportation Code § 547.613 breaks tint restrictions down by window position:

• Windshield: Tint allowed only above the AS-1 line or the top five inches, whichever is closer to the top. Must have at least 25 percent VLT and no more than 25 percent reflectance.
• Front Side Windows: Must allow at least 25 percent of light through. This applies to the windows immediately to the left and right of the driver.
• Rear Side Windows: No VLT minimum. Any darkness is permitted.
• Rear Windshield: Any darkness is allowed if the vehicle has dual outside mirrors reflecting at least 200 feet behind. Without those mirrors, 25 percent VLT is required.

One thing that sets Texas apart from many other states is that these legal window tint limits do not change based on vehicle type. Whether you drive a compact car or a full-size pickup, the same VLT requirements apply.

What Happens During a Traffic Stop for Window Tint?

Law enforcement officers across Texas carry portable VLT meters that measure light transmission through your windows. During a routine traffic stop, an officer can test your tint on the spot. The meter is pressed flat against the glass, and the reading determines whether your windows meet the 25 percent threshold.

VLT meters can produce slightly different readings depending on calibration, glass age, and where on the window the measurement is taken. Some drivers have had legal tint flagged because the meter read one or two percentage points below the threshold.

If you believe a reading was inaccurate, that is something a defense attorney can challenge. You are generally not required to consent to a tint test during a stop, but refusing may not prevent the officer from issuing a citation based on visual observation.

What Are the Penalties for Illegal Window Tint in Texas?

Operating a vehicle with noncompliant tint is a misdemeanor under § 547.613. First-offense fines are commonly reported to range from $20 to $25, depending on the jurisdiction, and repeat violations can run up to $275 or more. Installers who apply tint that does not meet state standards face fines of up to $1,000.

Beyond fines, illegal tint can cause your vehicle to fail the annual Texas safety inspection. You will need to remove or replace the tint before your registration can be renewed. In some cases, officers issue a fix-it ticket, giving you a window to correct the tint before further penalties apply.

Additional Texas Tint Rules Drivers Should Know

The legal window tint limits are just one part of the picture. The Texas Administrative Code, Title 37, Part 1, Rule 21.3 lays out several additional requirements:

• Restricted Colors: Red, blue, and amber-tinted films are prohibited on all vehicle windows.
• Manufacturer Certification: All tint film sold in Texas must be certified by the manufacturer to comply with state regulations through the Department of Public Safety.
• Compliance Sticker: Per § 547.609, a label stating the tint meets legal standards must be installed between the film and glass on the driver’s side window.
• Reflectivity Limits: Both front and rear side windows must not exceed 25 percent reflectance.
• Dual Mirror Requirement: If the rear window is tinted to any darkness, the vehicle must have outside mirrors on both sides reflecting at least 200 feet behind.

Failing to meet any of these requirements can result in a citation even if your VLT is within the legal range.

Can You Get a Medical Exemption for Darker Tint in Texas?

Yes. Texas allows medical exemptions for drivers with conditions that make them sensitive to sunlight, such as lupus, albinism, or certain skin disorders. To qualify, you need a signed statement from a licensed physician or optometrist that identifies your condition and explains why a darker tint is medically necessary.

The Texas Department of Public Safety no longer issues Window Tint Exemption Certificates. The physician’s letter itself now serves as your exemption. Keep a copy in the vehicle at all times. Even with a valid medical exemption, the windshield remains restricted. You can apply an untinted UV-protective film below the AS-1 line, but only if it reduces total visible light transmission by no more than five percent.

How to Make Sure Your Window Tint Is Legal

The simplest way to avoid problems is to use a professional installer who knows Texas Transportation Code § 547.613 and can verify compliance before you leave the shop. Ask for a manufacturer’s certificate of compliance and confirm the sticker has been placed on the driver’s side window. Some drivers opt for slightly lighter tint on the front windows, around 28 to 30 percent VLT, to create a buffer against variations in meter readings. Keep your compliance paperwork with your registration and insurance.
