Alabama Window Tint Laws (2026): Legal VLT Limits

Alabama sets a single tint standard for every vehicle registered in the state. The rear windshield and all side and door windows, front and back alike, must allow at least 32% of visible light through and may not reflect more than 20%. The front windshield is treated separately, and glass darkened before factory delivery is a recognized exception.

What is the legal tint limit in Alabama?

Alabama's window tint law is governed by Ala. Code 32-5C-1 through 32-5C-7. Before you read further, one key concept: a higher VLT percentage means lighter tint, while a lower VLT percentage means darker tint. So 32% is moderately dark, and anything darker (a lower number) would be illegal.

Ala. Code 32-5C-2(a)(2) does not sort windows into front and back, and it does not sort vehicles into cars and SUVs. It groups the rear windshield together with "the side or door windows" and applies one threshold to all of them: light transmission may not fall below 32%, and light reflectance may not rise above 20%, with a measurement tolerance of at least 3%. The front windshield is handled by its own subsection, 32-5C-2(a)(1), which allows no light-reducing material on it at all.

The statute also carries an enforcement condition that works in the driver's favor: the officer must be equipped with a light transmission meter before stopping the driver, and the reading must be taken before a person may be charged.

Factory-darkened glass behind the driver

The one place vehicle type enters the picture is not in 32-5C-2 but in the exceptions. Ala. Code 32-5C-3(6) exempts any vehicle "the windows or windshields of which have been tinted or darkened before factory delivery or permitted by federal law or regulation." The Alabama Law Enforcement Agency applies that exception to the windows behind the driver, stating that darker glass there is permitted as allowed by the vehicle manufacturer under federal law, and that an outside rearview mirror on each side of the vehicle is required when the darker glass is present. ALEA notes that the manufacturer determines the vehicle's classification.

Read that exception for what it actually says. It covers glass the manufacturer darkened, or darkening federal law permits for that vehicle. It is not a blanket permission to apply aftermarket film of any darkness behind the driver's row. If you are adding film to a vehicle that came with ordinary clear glass, the 32% floor in 32-5C-2 still governs those windows.

Windshield tint rules in Alabama

Alabama's windshield rule is a fixed measurement, not a reference to the AS-1 line that many other state statutes use. Ala. Code 32-5C-3(4) excepts "any transparent item which is not red or amber in color which is placed on the uppermost six inches of the windshield." The Alabama Code does not mention the AS-1 line anywhere.

Two conditions attach to that strip, and neither is about reflectivity. The item must be transparent, and it must not be red or amber in color. No tint of any kind is permitted on the main viewing area of the windshield below the six-inch strip.

Color does matter elsewhere in the chapter, so the red and amber ban on the windshield strip is the clearest color restriction in Alabama's tint law. On the rear windshield and the side and door windows, the operative limits are the 32% transmission floor and the 20% reflectance ceiling, which together rule out mirrored or metallic finishes that could dazzle oncoming drivers or law enforcement.

Medical exemptions

Alabama does allow a medical exemption for window tint darker than the standard legal limits. Under Ala. Code 32-5C-4(a), ALEA may issue an exemption to a person who must be shielded from the direct rays of the sun for medical reasons, covering any vehicle the person owns or in which the person is a habitual passenger. The application must be supported by a written statement from a physician licensed to practice medicine in Alabama, and ALEA may attach conditions and limitations.

Ala. Code 32-5C-4(b) singles out one condition for broader treatment. An exemption granted to a person with light-sensitive porphyria applies to all areas of the windshield and windows the physician prescribes in that written statement.

The verification mechanism is a decal, not glovebox paperwork. Ala. Code 32-5C-4(c) requires ALEA to design a decal carrying a unique identification number and to issue one to each person granted an exemption. The decal is placed on the windshield of each vehicle the exempt person operates, and ALEA may charge a reasonable fee for it. That decal is what answers an officer at the roadside, so the exemption is not fully in place until the decal is on the glass. ALEA routes medical waiver applications through the Driver License Division's Medical Records Unit.

How tint is measured and certified

Alabama uses a VLT meter (also called a photometer or tint meter) to measure the percentage of light passing through a window. The statute sets a measurement tolerance of at least 3%, so film nominally at the 32% standard is not treated as a violation on a reading a few points below it.

Alabama's compliance label requirement attaches to the vehicle, not to a category of licensed installer. Chapter 32-5C creates no tint installer licensing scheme. Ala. Code 32-5C-6 provides that a vehicle with light-reducing material applied to its windows or rear windshield "shall display a label visible from the outside of the vehicle" indicating compliance with the 32-5C-2 limits. The duty runs to the vehicle and its operator, so keep the label in place once it is affixed.

The labels themselves come from the film manufacturer. Ala. Code 32-5C-5 requires each manufacturer of tinting material to apply to the director for approval and registration of the material and its label before shipping it into Alabama, and to supply approved labels, written placement instructions, and notice that improper installation or failure to display a label violates state law. Altering or reproducing an approved label is itself unlawful.

If you are purchasing a vehicle with existing tint, ask the seller or a tint shop to verify the VLT readings with a meter before assuming the tint is legal. Film can degrade over time and may shift in either direction.

Penalties for illegal tint in Alabama

Violating Alabama's window tint law is a misdemeanor. Ala. Code 32-5C-7 sets three tiers rather than a simple first-and-after split:

Either penalty, or both together, may be imposed at each tier. The escalation is also time-limited in a way that matters: the second-tier and third-tier penalties apply only to an offense committed within one year after the date of the first offense. A citation years after an earlier one does not carry the escalated maximum.

In practice, law enforcement officers typically issue a citation and require you to bring the vehicle into compliance within a set period. However, because the violation is classified as a misdemeanor rather than a civil infraction, the potential consequences are more serious than in states that treat illegal tint as a simple fix-it ticket.

Liability is not limited to the driver. The second sentence of Ala. Code 32-5C-6 makes it unlawful for any person to install material that would put a window out of compliance with 32-5C-2, which reaches the shop that applied the film.

If you want to tint your windows in Alabama

The most important step is choosing a VLT that meets the 32% minimum, which applies to every side and door window and to the rear windshield. Many drivers opt for 35% film, which gives a meaningful reduction in heat and glare while staying comfortably above the legal floor after accounting for the measurement tolerance.

Choose a tint dealer familiar with the state code who will use approved material and affix the compliance label the vehicle must display under Ala. Code 32-5C-6. Ask for a written receipt or certificate showing the VLT of the film installed on each window. Store that documentation in your glove box.

If you have a medical condition that may qualify for an exemption, speak with your physician before installation. Getting the ALEA exemption and its decal first lets you choose a darker VLT without legal risk. If your vehicle came with factory-darkened glass behind the driver, confirm which windows that factory glass actually covers before assuming film may be added over or beside it.
