Is 20% Tint Legal in Arizona? VLT Laws Explained
Window tint laws in Arizona strike a balance between privacy and safety, and exceeding the legal limits can result in a fix-it ticket, fines, and vehicle inspection failures. Understanding Arizona's tinting regulations before you tint your windows—or choosing a tint shop—helps you avoid costly violations and keep your vehicle legal on the road.
Quick Reference: Arizona Window Tint Limits
| Window | Legal VLT % | Notes |
|---|---|---|
| Front Windshield | 70% (AS-1 line) | Must allow 70% of light above the AS-1 line |
| Front Side Windows | 33% | Driver and passenger side windows |
| Rear Side Windows | No limit | Any darkness allowed |
| Rear Window | No limit | Any darkness allowed |
What Is VLT and Why Does It Matter?
VLT (Visible Light Transmission) is a percentage that measures how much visible light passes through your window tint. A higher percentage means lighter tint; a lower percentage means darker tint. For example, 70% VLT tint blocks 30% of light, while 33% VLT blocks 67% of light.
In Arizona, the law sets minimum VLT standards for your windshield and front side windows to ensure drivers can see the road and law enforcement can see into the vehicle during traffic stops. Rear windows have no restrictions, giving you more flexibility with darker tints if desired. Staying within these limits keeps you compliant and safe.
Front Windshield Tinting Rules in Arizona
Arizona law allows you to tint your windshield, but only above the AS-1 line (the manufacturer's line marking where the sunshade begins on most vehicles). The tint applied above this line must allow at least 70% of visible light to pass through.
This rule exists so that the upper portion of your windshield remains clear enough for safe driving and visibility. If you choose to tint your entire windshield below the AS-1 line with a non-reflective material, that's allowed without a light transmission restriction, but most drivers opt for a windshield sun strip or full windshield tint that complies with the 70% limit. Check with your tint installer to confirm they apply tint in compliance with this requirement.
Front Side Window Requirements in Arizona
Both the driver's and passenger's front side windows are limited to a maximum of 33% VLT. This means your tint can block up to 67% of light on these windows.
33% tint is a popular choice in Arizona because it provides good heat rejection and privacy while maintaining reasonable visibility both into and out of the vehicle. This darkness level is legal and commonly seen on cars, trucks, and SUVs throughout the state. Your tint shop should always confirm they're applying 33% VLT (or lighter) to your front side windows to keep you compliant.
Rear Window and Rear Side Window Rules in Arizona
Arizona imposes no restrictions on tint darkness for rear side windows or your rear window. You can apply any level of tint—including limo tint or completely opaque tint—to the rear of your vehicle without violating state law.
This flexibility is one of Arizona's more relaxed regulations, allowing drivers to customize the rear for privacy and heat control as desired. Many drivers choose to match their rear tint to their front side windows for a uniform appearance, or go significantly darker in the back. As long as your front windshield and front side windows comply, your rear tinting choices are your own.
Restricted and Prohibited Tint Colors in Arizona
Arizona does not ban specific tint colors like red, amber, or blue. You can legally apply any color tint—including reflective tints—as long as you meet the VLT requirements for your windshield and front side windows.
However, reflective or mirrored tints on front side windows must not be excessively reflective, and Arizona law prohibits any material that significantly impairs visibility or creates a safety hazard. When in doubt, stick with standard gray or smoke-colored tints and confirm with your installer that any specialty color complies with state regulations.
Medical Exemptions for Window Tint in Arizona
Arizona does offer medical exemptions for window tinting, allowing drivers with certain medical conditions to exceed the standard VLT limits. Conditions that may qualify include photosensitivity, lupus, severe burns, and other light-sensitive disorders.
To obtain a medical exemption, you'll need a written certification from your physician stating that darker window tint is medically necessary. Submit this letter along with your vehicle registration and a written request to the Arizona Department of Transportation (ADOT). If approved, you'll receive an exemption document to keep in your vehicle. Law enforcement recognizes this exemption if you're stopped, so always carry it with you.
Penalties for Illegal Window Tint in Arizona
A violation of Arizona's window tint laws is typically issued as a fix-it ticket, often called a safety equipment violation. The fine is relatively modest—usually between $100 and $250—and you have a set period (often 10 days) to correct the violation by removing or lightening your tint.
If you don't address the violation, you may face additional penalties and difficulty passing vehicle inspections. Law enforcement may also cite you for obstructed visibility if tint is deemed unsafe. The best approach is compliance: choose a reputable tint shop that knows Arizona law and applies tint that meets state requirements.
