Alabama Window Tint Laws
Alabama treats passenger cars and multi-purpose vehicles differently. On a passenger car, every window except the windshield must let through at least 32 percent of light, back glass included, with a 3 percent tolerance. On an SUV, van or other multi-purpose vehicle, the front seat windows follow that same rule but the rear windows may be darker where the manufacturer allows it under federal law, with an outside mirror then required on each side. Only the top six inches of the windshield may be tinted, nothing may reflect more than 20 percent of light, and every install needs a dealer-affixed compliance sticker.
Alabama's tint rules are simpler than most states', and stricter than a lot of people assume. Every window on the car has the same limit, which removes the usual confusion about front versus rear. Here is the current picture, what it means in practice, and the one consequence most drivers do not think about.
The Legal Limits
VLT means Visible Light Transmission, the percentage of light the glass lets through. A lower number is darker. Alabama splits vehicles into two groups. On a passenger car or station wagon, every window other than the windshield has to let through at least 32 percent of light, with a 3 percent tolerance, and that includes the back glass. On a multi-purpose or recreational vehicle, an SUV or van in ordinary language, the windshield and front seat windows follow the same rule, but the rear windows may be darker where the vehicle manufacturer allows it under federal law. When that darker rear film is fitted, the vehicle must have an outside rearview mirror on each side.
The windshield is treated separately. Non-reflective tint is permitted on the windshield above the manufacturer's AS-1 line, which is the small marking etched into the glass near the top of most windshields. Below that line the windshield must stay clear.
Reflectivity is capped as well. Front and back side windows may not be more than 20 percent reflective, which is what rules out the heavily mirrored films you occasionally see from out of state.
The Windshield Rule
Alabama's own enforcement agency states this simply: only the upper six inches of the front windshield may be tinted, and the material applied has to be transparent. Everything below that stays clear.
You will see the AS-1 line referenced constantly in tint discussions, and it is a useful landmark. It is a small mark etched into the glass near the top corners of most windshields, put there by the manufacturer, and on many vehicles it sits at roughly that same height. It is not what Alabama's rule is written against though, so if your AS-1 marking sits lower than six inches down, go by the six inches. If you are unsure on your specific vehicle, ask before the film goes on rather than after.
Worth separating out: windshield protection film is a different product entirely. That is a clear, optically neutral layer that guards against rock chips, it is not a tint, and it does not darken anything.
Exemptions and the Compliance Sticker
Alabama allows medical exemptions for drivers with a physician-certified condition that requires limited sun exposure. If that applies to you, get the certification handled before the install, and keep the documentation in the vehicle.
Alabama also requires that the film be certified by its manufacturer for use in the state, and that a compliance sticker identifying the film be applied to the vehicle. A shop that installs legal film and does not sticker it is leaving you exposed on a technicality, so it is a fair question to ask.
What the 32 Percent Limit Means for Your Film Choice
Here is the part most drivers miss. In states with looser limits, people reduce heat by going darker. Alabama takes that option away, because the floor is 32 percent on every window. Darkness cannot be your heat strategy here.
That leaves the film itself as the only variable. A 32 percent dyed film and a 32 percent ceramic film are equally legal and behave completely differently in a July parking lot, because ceramic rejects infrared heat while dye mostly absorbs it. If your reason for tinting is a cooler car rather than privacy, the legal limit effectively forces the ceramic decision. That is why we lead with ceramic film in this market.
Where these figures come from, and one honest caveat: the numbers above are taken from the Alabama Law Enforcement Agency's own published tinting regulations, which draw on Act 96-534 and Title 32, Chapter 5C. We use ALEA rather than a third-party tint-law site because we checked several of those in August 2026 and they contradicted each other on whether SUVs may go darker at the rear. Statutes get amended and enforcement is a matter for law enforcement and the courts, not a tint shop, so treat this as our reading of the current rules rather than legal advice. If you are near a limit or relying on a medical exemption, confirm the current statute before you commit.

Frequently Asked Questions
What is the legal tint limit in Alabama?
It depends on what you drive. On a passenger car or station wagon, every window except the windshield must allow at least 32 percent light transmission, with a 3 percent tolerance, and that includes the back glass. On an SUV, van or other multi-purpose vehicle, the front seat windows are held to the same 32 percent, but the rear windows may be darker where the manufacturer allows it under federal law, and an outside mirror is then required on each side. Only the top six inches of the windshield may be tinted, and nothing may reflect more than 20 percent of light.
Is 20 percent tint legal in Alabama?
No. 20 percent VLT is darker than the 32 percent floor Alabama sets for the front sides, back sides and rear window, so it is below the legal limit. Shops outside Alabama sometimes quote 20 percent as a standard shade because it is legal in their state. Confirm the limit for the state the car is registered and driven in.
Can I tint my windshield in Alabama?
Only above the manufacturer's AS-1 line, and the film must be non-reflective. The AS-1 marking is etched into the glass near the top corners of most windshields. Below that line the windshield has to stay clear. Note that windshield protection film, which is a clear product that guards against rock chips, is a different thing entirely and is not a tint.
Does Alabama allow medical exemptions for darker tint?
Yes, with physician certification for a condition requiring limited sun exposure. Get the paperwork sorted before the install, and keep it in the vehicle. Tell your installer up front so the film is chosen and documented correctly.
Do I need a tint compliance sticker in Alabama?
Alabama requires that film be manufacturer-certified for use in the state and that a compliance sticker identifying the film be applied to the vehicle. It is a reasonable thing to ask any shop about before booking, because a legal film without the sticker still leaves you arguing the point at the roadside.
Does factory privacy glass count toward the limit?
Factory privacy glass is tinted during manufacture rather than filmed, and it is generally treated differently from aftermarket film. What matters is the combined VLT of the glass and any film you add on top, so if you are filming over privacy glass, tell the installer, because a light film over dark factory glass can still land you under the limit.
