What Is the Legal Tint in Arizona? Window Tint Laws Explained
Arizona has some of the most permissive window tint laws in the country — which makes sense given the intense desert sun. But "permissive" doesn't mean "anything goes." The state sets specific limits based on which window you're tinting, what type of vehicle you drive, and whether you have a medical exemption. Getting this wrong can mean a fix-it ticket, a failed inspection, or a fine.
How Window Tint Is Measured: VLT Explained
All tint laws are built around a single measurement: Visible Light Transmission (VLT). VLT is the percentage of visible light that passes through the glass and film combined.
- A higher VLT percentage means more light gets through — lighter tint
- A lower VLT percentage means less light gets through — darker tint
So a 70% VLT film is nearly clear, while a 5% VLT ("limo tint") is nearly opaque. When Arizona law sets a minimum VLT, it's telling you how much light must still pass through.
Arizona Tint Laws by Window and Vehicle Type 🌵
Arizona draws a clear line between sedans/coupes and SUVs/vans/trucks. The rules differ depending on which vehicle category you own.
Passenger Vehicles (Sedans and Coupes)
| Window | Legal Requirement |
|---|---|
| Windshield | Non-reflective tint allowed on the top 5 inches only |
| Front side windows | Must allow more than 33% VLT |
| Rear side windows | Any darkness allowed |
| Rear window | Any darkness allowed |
SUVs, Vans, and Trucks
| Window | Legal Requirement |
|---|---|
| Windshield | Non-reflective tint allowed on the top 5 inches only |
| Front side windows | Must allow more than 33% VLT |
| Rear side windows | Any darkness allowed |
| Rear window | Any darkness allowed |
In Arizona, front side windows are treated the same across vehicle types — 33% VLT is the threshold. Rear windows get much more flexibility for both categories.
Reflectivity Rules
Arizona also restricts how reflective window film can be. Metallic or mirrored tints can blind other drivers, which is why the law limits this regardless of VLT.
- Front side windows: Must not be more than 35% reflective
- Rear side windows: Must not be more than 35% reflective
Standard dyed films usually fall well within this limit. Highly metallic or chrome-style films are where drivers tend to run into problems.
Other Requirements Arizona Enforces
A few additional rules apply regardless of which window you're tinting:
- Dual side mirrors: If the rear window is tinted, Arizona requires dual side mirrors — one on each side of the vehicle — so the driver retains adequate rear visibility
- Film certification: Arizona does not currently require tint manufacturers to certify their film for the state, but this can vary — check with your installer
- Sticker requirement: Arizona does not require a compliance sticker between the film and glass, unlike some other states
- Color restrictions: Tint colors are generally not restricted under Arizona law, though red and amber films may create confusion with vehicle lighting signals and are best avoided
Medical Exemptions in Arizona
Arizona allows medical exemptions for darker tint on side and rear windows. If a driver or passenger has a condition that requires protection from sunlight — such as lupus, photosensitivity disorders, or certain skin conditions — they may be eligible to apply darker film that would otherwise be illegal.
To qualify, you typically need documentation from a licensed physician. The exemption is attached to the vehicle, not the person, and the documentation is generally kept in the vehicle. The process goes through the Arizona Department of Transportation (ADOT), though specifics can change — confirm current requirements directly with ADOT.
Why Arizona's Tint Laws Are More Lenient Than Most States
Arizona's climate is a direct reason the state allows darker rear tint without restriction. Interior temperatures in parked vehicles can reach 150°F or higher during summer, and tinted windows meaningfully reduce heat buildup, UV exposure, and sun glare. The legislature has balanced road safety concerns — primarily front visibility — with the practical need for sun protection.
That said, Arizona law enforcement does enforce front window violations, and 33% VLT on front side windows is a real limit, not a suggestion. Officers use tint meters to measure compliance at traffic stops.
What Shapes Your Actual Situation 🔍
Even within Arizona, several variables affect how tint laws apply to your vehicle:
- Vehicle type — sedan vs. SUV changes which windows have flexible limits
- Year and make — some factory glass already has a built-in VLT from the manufacturer, which counts toward the total measurement
- Medical status — a verified medical need opens different options
- Local enforcement — while state law is uniform, enforcement intensity can vary by county or municipality
- Film quality and installer accuracy — film that's labeled "35% VLT" may not perform exactly at that level once applied to glass with its own tint value
The 33% front window rule is straightforward enough. But once you factor in your specific vehicle's factory glass, which film you're using, and the combined VLT measurement, the real-world number gets more nuanced. That combined measurement — not just the film's rating alone — is what an officer or inspector would measure.
