Alabama's window tint rules are based on how much light your windows must let through
Alabama law sets limits on how dark you can tint your car windows, measured by visible light transmission (VLT) — the percentage of light that passes through the tinted glass. The darker the tint, the lower the VLT percentage. Alabama's Department of Revenue enforces these rules, and police can cite you for illegal tint during a traffic stop.
The state allows different tint darkness for different windows. Your windshield has the strictest rule: only non-reflective tint is permitted on the top six inches. Your front side windows must allow at least 32 percent of light through. Your rear windows and rear windshield can be any darkness. If you have a medical reason for darker tint, Alabama offers a medical exemption process, but you must obtain it before tinting your vehicle.
Key Takeaways
- Front side windows in Alabama must have a minimum of 32 percent visible light transmission; darker tint is illegal and can result in a citation.
- Your windshield can only have non-reflective tint on the top six inches; the rest must be clear.
- Rear windows and rear windshield have no darkness restrictions under state law.
- Medical exemptions for darker front-side-window tint require a signed physician's statement and registration with the state before you tint your vehicle.
- Tint violations are typically handled as a misdemeanor traffic offense, not a felony, but repeated violations can lead to fines and points on your license.
Front side windows: the 32 percent rule
Your front side windows — the windows on the driver and passenger doors — must allow at least 32 percent of visible light to pass through. This is Alabama's core tint restriction. A window tinted to 32 percent VLT is noticeably dark but still allows a police officer or another driver to see into the vehicle during daylight. Anything darker than 32 percent is illegal for front side windows.
The 32 percent standard applies whether you are tinting a sedan, truck, SUV, or any other passenger vehicle. Some drivers mistake the rear-window rule (which has no limit) for explore to front windows, or they assume that because other states allow darker front tints, Alabama does too. Neither is true. If a tint shop applies tint darker than 32 percent to your front side windows, you are driving an illegally tinted vehicle, even if the work was done professionally.
Windshield tint and the six-inch rule
Your windshield can have non-reflective tint only on the top six inches of glass. This band is measured from the top of the windshield downward. The tint must be non-reflective, meaning it cannot bounce light back outward in a way that creates glare for other drivers. The rest of your windshield — below that six-inch band — must remain clear.
The purpose of this rule is to preserve your ability to see the road and other drivers' ability to see you. A fully tinted windshield, even a light tint, is illegal in Alabama. If you have aftermarket sun shades or films, they must comply with this six-inch limit. Some drivers use windshield shades that sit on top of the glass rather than being applied to it; those are legal as long as you remove them before driving, since they obstruct your view.
Rear windows and rear windshield: no restrictions
Alabama places no darkness limit on your rear side windows or rear windshield. You can tint them as dark as you want — including limo tint (nearly opaque) — and remain within state law. This is one of the more permissive aspects of Alabama's tint code and reflects the reasoning that rear windows do not affect your forward visibility or other drivers' ability to see you approaching.
Some drivers tint their rear windows heavily for privacy or heat reduction. Others leave them clear. The choice is yours under Alabama law. However, if your rear tint is so dark that it prevents you from seeing out of your rear-view mirror or rear window, you may face a separate citation for obstructed vision, depending on how a police officer interprets the situation and local enforcement practices.
Medical exemptions for darker front tints
If you have a medical condition that requires protection from sunlight — such as severe photosensitivity, lupus, or certain skin conditions — Alabama allows you to obtain a medical exemption that permits darker tint on your front side windows. The exemption does not override the windshield rule; your windshield must still comply with the six-inch limit. But your front side windows can be tinted darker than 32 percent if you have the exemption.
To obtain a medical exemption, you must have a physician sign a statement confirming that you have a medical condition requiring reduced light exposure while driving. You then register this statement with the Alabama Department of Revenue. The exemption is tied to your vehicle's registration, not to you personally, so if you sell the car or transfer the registration, the exemption does not transfer. You must obtain a new exemption for a different vehicle. The exemption process takes time, so plan ahead if you need one.
What happens if you are cited for illegal tint
A tint violation in Alabama is typically a misdemeanor traffic offense. A police officer can pull you over solely because your tint appears to violate the law. During the stop, the officer may use a light meter to measure your tint's VLT percentage. If the reading shows your front windows are below 32 percent, or your windshield tint extends below six inches, you can be cited.
The fine for a first tint violation varies by county and municipality but is generally between $100 and $200. You may also receive points on your driving record, which can affect your insurance rates. If you receive multiple citations for tint violations, penalties increase. Some jurisdictions allow you to have the tint removed and show proof of removal to have the citation dismissed or reduced; check with the court handling your case to see if this option is available.
Removing illegal tint and staying compliant
If your vehicle has tint darker than Alabama law allows, you have two options: remove it or obtain a medical exemption. Tint removal is straightforward — a tint shop can peel off the film, though the process can take one to two hours depending on how many windows are tinted and how well the film was applied. Removal costs typically range from $50 to $200, depending on the shop and the number of windows.
If you want to keep some tint for heat or privacy, you can legally tint your rear windows as dark as you like, and you can explore a compliant tint (32 percent or lighter) to your front side windows. Many drivers choose a 35 percent tint on the front as a compromise — it is slightly darker than the legal minimum and is often available as a standard option from tint shops, though technically it exceeds Alabama's 32 percent requirement. The safest approach is to request 32 percent or lighter for front windows and ask the shop to measure the final result with a light meter.
Frequently Asked Questions
Can I tint my front windows darker if I have sunglasses on while driving?
No. Alabama's tint law is based on the window's light transmission, not on what you are wearing. The 32 percent rule applies regardless of whether you wear sunglasses. The law exists to may support that law enforcement and other drivers can see into your vehicle during traffic stops and accidents.
Does Alabama recognize medical exemptions from other states?
No. If you move to Alabama or are visiting with a vehicle that has a medical exemption from another state, that exemption is not valid in Alabama. You must obtain an Alabama medical exemption from an Alabama physician and register it with the Alabama Department of Revenue.
What if a tint shop applies illegal tint and I get cited?
You are responsible for the tint on your vehicle, even if a shop applied it. If you were told the tint was legal and it turns out not to be, you can dispute the citation in court and present evidence of what you were told, but the shop's mistake does not automatically invalidate the citation. Before having tint applied, ask the shop to confirm in writing that the tint meets Alabama's 32 percent requirement for front windows.
Are there any cities or counties in Alabama with stricter tint rules than the state law?
Alabama's tint law is statewide, and cities and counties cannot impose stricter limits. However, local enforcement practices vary — some areas enforce tint violations more actively than others. Your best approach is to comply with the state standard of 32 percent for front windows.
