Arizona Window Tint Laws: VLT Limits, Exemptions, and Fines

Arizona window tint laws let you darken every piece of glass on a passenger vehicle, but the rules change depending on which window you’re tinting. Front side windows must allow at least 33 percent of visible light through, plus or minus 3 percent. Rear side windows and the rear windshield can go as dark as you want. Reflectivity on any tinted side window is capped at 35 percent, plus or minus 3 percent. All of this sits in Arizona Revised Statutes § 28-959.01, and getting it wrong usually means a civil traffic citation and a return trip to the tint shop.¹

Darkness and Reflectivity Limits by Window

The front driver and passenger windows are the most tightly regulated glass on the vehicle. Any film applied there must allow a visible light transmission (VLT) of at least 33 percent, with a 3 percent tolerance. That means a combined glass-and-film reading as low as roughly 30 percent is still legal, though most installers aim right at 33 to stay inside the margin.¹

Reflectivity is a separate measurement from darkness. It captures how much light the film bounces back outward, which is what produces a mirrored look. On the front side windows, film reflectivity is capped at 35 percent, plus or minus 3 percent. A film can meet the darkness rule and still fail if it’s too reflective.¹

Behind the driver, the rules relax significantly. Rear side windows have no VLT floor in the statute. The only limit on them is the same 35 percent reflectivity cap. You can run limo-dark film on them as long as the finish isn’t excessively mirrored.¹

The rear windshield follows its own rule. You can apply any level of tint to it as long as your vehicle has outside mirrors on both the left and right sides that give you a view of at least 200 feet behind the vehicle. Since almost every modern car and SUV comes with dual side mirrors, most drivers can tint the rear glass to any darkness.¹

Windshield Tint Strip

You can tint the top of your windshield, but Arizona measures the strip differently from most states. Instead of referencing the manufacturer’s AS-1 line, the statute requires that the bottom edge of the tint sit at least 29 inches above the driver’s seat when the seat is in its lowest and rearmost position, measured from a point five inches in front of the bottom of the backrest. On a typical sedan or truck, that works out to a strip roughly four to six inches down from the top of the glass, depending on seat height and windshield angle.¹

The windshield strip cannot be red or amber. Those colors overlap with emergency lighting and traffic signals, which is why they’re singled out. The statute lists no other color restrictions for the strip.¹

Why Your Film Rating Isn’t Your Final VLT

Factory automotive glass is not perfectly clear. Most of it leaves the manufacturer with a built-in tint that allows somewhere between 70 and 85 percent of light through on its own. When you apply aftermarket film over factory glass, the two transmissions multiply, and the combined number is always lower than the film’s rating alone.

Picture a front side window that transmits 74 percent of light bare. Apply a 35 percent VLT film over it and the net reading comes out around 26 percent, which fails the 33 percent threshold. To land inside the law with typical factory glass, installers often use film rated around 45 to 50 percent on front side windows. A reputable shop will meter your bare glass with a tint meter before recommending a shade. Insist on that step if you want to avoid buying a ticket along with your tint.

Medical Exemption

If a medical condition requires you to limit sun exposure, you can apply for an exemption from the standard limits. You’ll need a written statement from a physician licensed under Title 32, Chapter 13, 14, or 17 of the Arizona Revised Statutes, which covers doctors of medicine, osteopathic physicians, and naturopathic doctors. The statement must confirm that you need to be shielded from direct sunlight for medical reasons.¹

With that documentation, you apply to the Arizona Department of Transportation, which has authority to issue the exemption. It covers a vehicle you own or one in which you’re a regular passenger. The statute does not explicitly require you to carry the exemption paperwork with you, but keeping a copy in the glove box is the practical move. If an officer meters your windows during a stop, having the documentation on hand heads off a citation you’d otherwise need to contest in court.¹

What a Ticket Costs You

A tint violation in Arizona is a civil traffic offense. Officers check compliance with a handheld tint meter during traffic stops. If your windows fail, you’ll usually receive a corrective notice, essentially a fix-it ticket giving you time to remove or replace the illegal film and bring proof of correction to the court.

Fine amounts for civil traffic violations vary by court and jurisdiction, so there is no single statewide dollar figure. If you ignore the ticket or don’t fix the tint, the court can impose a monetary penalty and the violation lands on your driving record. Tint citations are equipment violations rather than moving violations, so a single one carries less weight than a speeding ticket. Repeat offenses draw more scrutiny and larger fines.

The ticket isn’t the only exposure. If you’re in an accident with non-compliant windows, your insurer may decline to cover damage to the tinted glass. A tint violation on your record can also nudge your rates the way any traffic citation can. One corrected fix-it ticket is a small risk; a pattern of them is not.

Driving Out of State or Running a Commercial Vehicle

Arizona-legal tint is not automatically legal in neighboring states. California and New Mexico apply stricter front-window limits, and film that passes a meter in Phoenix can fail one across the state line. Arizona law requires anyone who sells or installs window film to conspicuously disclose that applying it to driver or passenger side windows may be illegal in other states, which is worth remembering before a road trip.²

Commercial vehicles follow a different, stricter rule. Under federal regulation, the windshield and the windows immediately to the driver’s left and right on a commercial motor vehicle must maintain at least 70 percent light transmission, well above Arizona’s 33 percent standard for passenger cars. The 70 percent rule applies only to those openings; rear and cargo-area glass can be tinted more freely.³⁴ Federal commercial vehicle rules offer no individual medical exemption for darker tint, so a CDL holder who needs sun protection is limited to prescription eyewear or a compliant windshield visor strip while on duty.
