How Dark Can You Tint Your Windows in Alabama? A Complete Guide to Tint Laws
Window tinting adds style, reduces heat, protects interiors — but if you live in Alabama, you also need to stay within the law. Whether you're a driver, homeowner, or business owner, this guide explains exactly how dark you can go, what’s legal on the road, and what’s smart for homes and offices.
Why Tint Laws Matter in Alabama
Tint darkness isn’t just about comfort or looks — it’s a visibility and safety issue for law enforcement and other drivers. Alabama, like many states, has clear restrictions on how much light your windows are legally required to let in.
Violating these laws can lead to:
- Fines or tickets
- Vehicle inspection failures
- Orders to remove the tint
Let’s break down the rules — starting with your car.
Legal Window Tint Limits for Cars in Alabama
Alabama's tint laws are measured using VLT% (Visible Light Transmission) — the percentage of visible light that passes through your windows.
🚗 Passenger Vehicles (Sedans)
| Window | Legal Limit (VLT%) |
|---|---|
| Windshield | Non-reflective tint allowed above AS-1 line or top 6 inches |
| Front Side | ≥ 32% VLT |
| Rear Side | ≥ 32% VLT |
| Rear Windshield | ≥ 32% VLT |
🚙 SUVs, Vans, Trucks (Multipurpose Vehicles)
| Window | Legal Limit (VLT%) |
|---|---|
| Windshield | Same as sedans |
| Front Side | ≥ 32% VLT |
| Rear Side | Any darkness allowed |
| Rear Windshield | Any darkness allowed |
Other Notes:
- Reflectivity: No window may reflect more than 20% of light.
- Tint Colors: Red and amber tints are illegal.
- Medical Exemptions: Permitted with proper documentation.

How to Know If Your Tint is Legal
Most reputable tint shops in Florence or Muscle Shoals will stay within the law, but if you're buying a used vehicle or DIY'ing your tint, check with a VLT meter (many inspection stations use these). Police can — and do — pull over drivers for suspected illegal tint.
Is 20% Tint Legal in Alabama?
Short answer: Not for your front windows.
- 20% VLT is too dark for front side windows or rear glass on sedans.
- Only SUVs, vans, or trucks may use 20% (or darker) on rear windows only.
- If your sedan has 20% all around, you’re at risk of getting cited.
What About Tinting Homes and Businesses?
Alabama’s tint laws only apply to vehicles. For residential or commercial windows, you can go as dark or reflective as you want — but here’s the tradeoff:
🌡 Energy & Comfort
- 5%–20% VLT tints drastically reduce heat and glare
- Reflective tints (mirror-like) push even more heat away, ideal for west-facing windows
🏢 Privacy & Aesthetics
- Commercial offices often use mirror or charcoal tints for privacy and branding
- Homeowners near busy roads or urban areas prefer 15–25% tint for added privacy without blacking out rooms
🌅 Smart Tip
Some extremely dark tints can reduce natural light too much. In bedrooms and home offices, a lighter film (35–50%) might be a better long-term choice.
Medical Exemptions for Vehicle Tint
Drivers with conditions like lupus, melanoma, or photosensitivity may qualify for darker tints.
To apply for an exemption in Alabama:
- Download and complete the Application for Window Tinting Medical Exemption from ALEA.
- Submit medical verification signed by a licensed physician.
- Wait for approval and keep exemption paperwork in the vehicle.
Tint Law Enforcement in Florence & the Shoals
Florence PD and state troopers do enforce tint regulations. You’re most likely to be pulled over if:
- Your tint is visibly darker than stock
- Your vehicle is registered out-of-state but appears heavily modified
- It's nighttime or you're stopped for another traffic issue
Avoid problems by keeping receipts from your tint installer showing the VLT percentage.
Final Thoughts: How Dark Should You Go?
- Want maximum privacy and have a truck or SUV? Go as dark as you like on rear glass.
- Want legal peace of mind? Stick with 35% VLT or higher on front side windows.
- For homes and offices, let function guide your decision — not fashion.
