Alabama distinguishes passenger cars from manufacturer-classified multipurpose and recreational vehicles. Check the vehicle classification before choosing darker film for the rear.
Read the official sources ↓Rules by window
| Window | Requirement |
|---|---|
| Windshield | Transparent material is allowed only on the uppermost six inches under the ordinary rule; red and amber are excluded from this exception. |
| Front side | At least 32% light transmission. |
| Rear side | Passenger cars and station wagons: at least 32%. Qualifying multipurpose and recreational vehicles may use darker rear tint within the federal/manufacturer allowance. |
| Rear window | Passenger cars and station wagons: at least 32%. The qualifying rear-window exception requires exterior mirrors on both sides. |
Reflection, approved materials and labels
Ordinary side and rear tint must not exceed 20% light reflectance. Manufacturers must obtain approval and registration for their tint materials and compliance labels. The vehicle must display a compliance label visible from outside; ALEA says a tint dealer must affix it.
Medical exemptions
Apply to ALEA with a written statement from an Alabama-licensed physician. The exemption may cover a vehicle the applicant owns or regularly rides in and may carry conditions. For light-sensitive porphyria, the approved exemption covers the windshield and window areas prescribed by the physician. ALEA issues a uniquely numbered windshield decal and may charge a reasonable fee.
Other statutory exceptions
Section 32-5C-3 separately addresses factory or federally permitted glazing and vehicles not registered in Alabama. Section 32-5C-2 also exempts personal-use vehicles belonging to and occupied by an active or retired state, local or federal law-enforcement officer, with law-enforcement identification carried while driving.
Before installation
Have the installer measure the existing glass and the finished window. A film’s advertised VLT does not establish transmission through both layers. Manufacturer classification controls the multipurpose/recreational rear-window allowance described by ALEA.
