In Arizona, legal tint is measured by VLT — the percentage of light the filmed glass lets through. The numbers below are the darkest tint the law allows at each window position, labeled VLT MAX: install film darker than the listed VLT and the vehicle is out of compliance. Figures are compiled from official Arizona state sources; laws change, so confirm the current statute before you tint.
| Window | Darkest Legal (VLT MAX) | Reflectivity |
|---|---|---|
| Front side windows (and front side wing vents) | Light transmission 33% plus or minus 3%, measured with the material and the glazing combined; luminous reflectance 35% plus or minus 3% | |
| Side windows behind the driver | No darkness limit — the only cap is luminous reflectance 35% plus or minus 3% or less | |
| Rear window | No darkness limit — luminous reflectance 35% plus or minus 3% or less; and the rear window is excepted from the section altogether when the vehicle has outside mirrors on both sides, each reflecting a view of the highway at least 200 feet to the rear | |
| Windshield | Transparent material on the topmost portion only; the bottom edge must sit at least 29 inches above the undepressed driver's seat (measured from a point five inches in front of the bottom of the backrest, seat in its rearmost and lowermost position, vehicle on a level surface); the material may not be red or amber |
How to Read These Numbers
- Front side windows (and front side wing vents): Front side windows — driver and front passenger — are the most tightly regulated and the ones checked first at a traffic stop or inspection.
- Rear window: The rear window rule often interacts with side mirrors: darker rear glass typically requires dual outside mirrors.
- Windshield: The windshield rule controls the strip at the top of the glass and how far film or a visor band may extend down. Most states allow a non-reflective strip above the manufacturer's AS-1 line.

Arizona Tint Law Questions
What is the darkest legal tint in Arizona?
For front side windows, Arizona allows tint down to Light transmission 33% plus or minus 3%, measured with the material and the glazing combined; luminous reflectance 35% plus or minus 3% — the VLT MAX. Rear windows may allow darker film; check the table above for each position.
What happens if my tint is darker than Arizona allows?
Over-dark tint can draw a citation and, in many states, a fix-it order requiring the film to be removed and the vehicle re-inspected. Laws also change — verify the current statute before tinting.
