In Alabama, window tint is illegal when it blocks too much light, reflects too much light, or covers parts of the windshield it isn’t allowed to cover. The core rule for what tint is illegal in Alabama is the 32% visible light transmission (VLT) floor: on a standard passenger car, any side window or the rear window that lets less than 32% of light through violates state law, as does any side window that reflects more than 20% of light. A first offense is a misdemeanor carrying a fine up to $100 and up to 10 days in jail.1Alabama Legislature. Alabama Code Title 32, Chapter 5C – Section 32-5C-7 Penalties
Darkness Limits That Make Tint Illegal
Alabama’s tint rules live in Title 32, Chapter 5C of the state code, and the legal line depends on the type of vehicle and the window in question.
Passenger Cars
On sedans, coupes, and similar passenger vehicles, every side window and the rear window has to allow at least 32% of light through. The same floor applies all the way around the car, so you can’t legally run darker film on the back glass than on the front doors. Alabama builds in a 3% measurement tolerance, which means a tint meter reading of 29% would still pass.
SUVs, Trucks, and Vans
Multipurpose vehicles follow the 32% rule on the front side windows, but the windows behind the driver can go darker to the extent the vehicle manufacturer and federal law allow. Factory privacy glass on the rear and back side windows is permitted even when it reads well under 32%.
Windshields
Only the top six inches of the windshield can be tinted, the material there has to be transparent, and it cannot be red or amber.2Alabama Legislature. Alabama Code Title 32, Chapter 5C – Section 32-5C-3 Exceptions Any tint film applied below that strip is illegal, regardless of how light it is.3Alabama Law Enforcement Agency. Alabama Tinting Regulations
Reflectivity and Labels
Even tint that passes the 32% test can still be illegal if it is too reflective. Front and back side windows cannot reflect more than 20% of light, which rules out the mirror-finish metallic films.3Alabama Law Enforcement Agency. Alabama Tinting Regulations Color is not restricted, so bronze, charcoal, or any other shade is fine as long as the VLT and reflectivity numbers work.
Aftermarket tint also has to carry a compliance label visible from outside the vehicle, confirming it meets the VLT and reflectivity limits in Section 32-5C-2. The film’s manufacturer is required to supply those labels along with placement instructions before shipping into Alabama.4Alabama Legislature. Alabama Code Title 32, Chapter 5C – Section 32-5C-6 Display of Labels Indicating Compliance A missing or altered label can be charged as a separate violation and gives an officer an obvious reason to pull out a tint meter.
When Darker Tint Is Legal
A handful of situations take you outside the standard limits.
If you have a medical condition that calls for extra protection from sunlight, you can apply to the Alabama Law Enforcement Agency (ALEA) for an exemption. The application requires a written statement from an Alabama-licensed physician confirming the medical need. If ALEA approves it, the agency issues a decal with a unique identification number that goes on the windshield of each covered vehicle, and that decal is what tells an officer your darker tint is authorized.5Alabama Legislature. Alabama Code Title 32, Chapter 5C – Section 32-5C-4 Medical Exemptions The exemption can cover any vehicle you own or regularly ride in, and ALEA may attach specific conditions.
Vehicles not registered in Alabama are not subject to the state’s tint restrictions while driving through, and factory tint or darkening that was in place when the vehicle left the manufacturer is also exempt.2Alabama Legislature. Alabama Code Title 32, Chapter 5C – Section 32-5C-3 Exceptions Required federal, state, or local stickers on a window don’t count against your tint calculation. The out-of-state exemption cuts both ways: Alabama won’t ticket a visitor for darker tint, but if you take Alabama-legal tint into a stricter state, that state’s rules can apply.
Penalties and the One-Year Clock
A tint violation is a misdemeanor, and the penalty grows with each repeat offense committed within one year of the first:
- First offense: fine up to $100, up to 10 days in jail, or both.
- Second offense: fine up to $200, up to 30 days in jail, or both.
- Third or subsequent offense: fine up to $500, up to three months in jail, or both.1Alabama Legislature. Alabama Code Title 32, Chapter 5C – Section 32-5C-7 Penalties
The one-year window runs from the date of the first offense, not the first conviction. Expect to be ordered to remove or replace the illegal film regardless of which offense it is, and professional removal typically runs a few hundred dollars on top of the fine. Leaving the illegal tint on the car almost guarantees a second or third violation at the next stop.
How Officers Check Tint
During a traffic stop, officers use a handheld electronic tint meter that reads the percentage of light passing through the glass. These devices are generally accurate within about two percentage points, and Alabama’s built-in 3% tolerance absorbs some of that instrument variability, so a reading a point or two under 32% doesn’t automatically produce a citation.3Alabama Law Enforcement Agency. Alabama Tinting Regulations Officers also check for the compliance label on aftermarket tint and, for anyone running darker film, the ALEA medical decal on the windshield.
