Window Tint Laws in Alabama
The exact legal darkness allowed on every window of your vehicle in Alabama, plus reflection limits, the medical exemption, and what a ticket costs.
How dark you can legally go
Visible-light transmission (VLT) allowed for each window.
Common tint shades, and whether they're legal here
What the shop sells, mapped to the Alabama limit.
| Film shade | Front side | Back & rear |
|---|---|---|
| 70% (light) | Legal | Legal |
| 50% | Legal | Legal |
| 35% (factory look) | Legal | Legal |
| 20% | Too dark | Too dark |
| 5% (limo) | Too dark | Too dark |
Alabama sets one number for every window that can be tinted: 32% (±3%). Factory privacy glass darker than 32% on the rear and back side windows of SUVs, vans, and trucks is allowed because it is original manufacturer glazing, not aftermarket film (§32-5C-2).
Film is sold by its own VLT, but police measure the installed darkness: the film combined with your factory glass. Ask the shop for the net, as-installed VLT before you buy.

Penalties & how it's enforced
What happens if your tint is too dark.
Act 2021-451 (effective 2021-01-01): The 32% standard has held since the chapter took effect (Act 96-534, Aug 15, 1996). A 2021 amendment (Act 2021-451) adjusted administrative provisions without changing the VLT numbers.
The medical exemption: how to qualify
For drivers with a documented light-sensitivity condition.
What Alabama drivers get wrong
Alabama keeps window tint simple: one number, 32% (±3%), for the front doors, the back side windows, and the rear glass alike. Aftermarket film on the windshield is limited to a transparent, non-reflective strip across the top 6 inches, and no window film may bounce back more than 20% of light. The one wrinkle is factory privacy glass: an SUV or van that left the plant with dark rear glass is legal at that darkness because it is original glazing, not film you added.
Common questions
What is the legal tint limit in Alabama?
Every window that can carry aftermarket film must allow at least 32% of light through, with a 3% measurement tolerance. That single number covers the front side windows, the back side windows, and the rear window. The windshield gets only a transparent strip on the top 6 inches.
Is factory privacy glass legal in Alabama?
Yes. Rear and back side windows that came dark from the manufacturer are legal at that darkness even if they read below 32%, because they are original glazing rather than aftermarket film. The 32% rule applies to film you add.
Does Alabama offer a medical exemption for window tint?
Yes, under §32-5C-4. You apply through the Alabama Law Enforcement Agency with a physician certifying a condition that requires reduced light. ALEA can set conditions on the exemption.
