Arizona Window Tint Laws: Complete Legal Guide

Window tint can reduce glare, protect your interior, and keep your vehicle cooler—but only if it meets Arizona's legal requirements. Breaking tint laws in Arizona can result in traffic citations, failed vehicle inspections, and the costly hassle of having your tint removed. Understanding the state's specific regulations will help you enjoy the benefits of tint without legal trouble.

Quick Reference Table

Understanding VLT (Visible Light Transmission)

VLT stands for Visible Light Transmission, which measures what percentage of light passes through your window tint. If a tint has 50% VLT, that means 50% of visible light comes through the tint, while 50% is blocked. The higher the VLT percentage, the lighter the tint; the lower the percentage, the darker it is.

Arizona's VLT limits are designed to balance privacy and safety. Darker tints may look great, but excessively dark front windows reduce visibility for you and other drivers, which is why Arizona enforces stricter limits on front windows compared to rear windows. Knowing your vehicle's current tint darkness and the legal limits will save you from citations.

Front Windshield Rules

Arizona allows window tint on your front windshield, but only above the manufacturer's AS-1 line (the line marked on the windshield). The tint must be non-reflective and allow at least 70% of light to pass through. This means you can only use very light tints on the upper portion of your windshield.

Many drivers use clear protective films or very light tints on the AS-1 area for sun protection and safety purposes. If you're considering front windshield tint, work with a professional installer who understands exactly where the AS-1 line is on your specific vehicle model.

Side Window Rules

Arizona distinguishes between front and rear side windows with different regulations. Your front side windows (driver and passenger windows) must allow at least 50% of light through, making them moderately light. This is a recent change—Arizona tightened its front window rules in recent years to improve driver visibility and road safety.

Your rear side windows have no legal limit in Arizona. You can tint them as dark as you want, including limo tint or full darkness. This flexibility gives you privacy in the back while maintaining safe visibility from the driver's seat. When installing tint, ensure your installer understands the difference between front and rear side windows, as mixing these up is a common mistake.

Rear Window Rules

Arizona has no darkness restrictions for your rear window. You can apply any level of tint darkness to the rear window—even complete darkness—without legal consequences. This allows maximum privacy and heat rejection in the rear of your vehicle.

If your vehicle has dual side mirrors (a mirror on each side), you're still allowed to tint your rear window completely dark. The dual mirrors serve as your backup visibility aid, so the law doesn't require rear windows to remain transparent.

Restricted Colors

Arizona does not ban specific tint colors like red or amber. You're free to use any color tint, including reflective or metallic finishes, as long as you meet the VLT requirements for your window type. However, reflective tints are allowed on the front windshield above the AS-1 line, while side windows should use non-reflective tints to avoid creating glare that distracts other drivers.

Medical Exemptions

Arizona does offer medical exemptions for window tint. If you have a medical condition—such as severe sun sensitivity, lupus, or certain skin disorders—that requires additional sun protection beyond standard tint limits, you can apply for an exemption.

To obtain a medical exemption, you'll need to submit a written request to the Arizona Department of Transportation (ADOT) along with documentation from a licensed physician explaining your medical necessity. Your doctor must specify why darker tint is medically required. Once approved, you'll receive an exemption certificate to keep in your vehicle. This certificate protects you from tint-related citations, though law enforcement may still ask to see your medical documentation during traffic stops.

Penalties for Illegal Tint

If your tint violates Arizona's laws, you can receive a traffic citation. Non-moving violation tickets for illegal tint typically range from $100 to $250, depending on the severity and your jurisdiction. Some officers issue "fix-it tickets," which allow you to remove or adjust your tint and have the citation dismissed upon proof of correction.

During vehicle inspections—whether for registration or safety—illegal tint will cause your inspection to fail. You'll need to have the tint adjusted or removed before passing reinspection. Repeat violations or refusing to correct illegal tint could result in vehicle registration suspension.
