Legal window tint in Arizona comes down to a few specific numbers: front side windows must transmit at least 33% of visible light, the windshield can carry only a tinted strip whose bottom edge sits at least 29 inches above the driver’s seat, and no window may exceed 35% reflectance or use red or amber film. Rear side windows and the back window have no darkness limit at all. The rules live in A.R.S. § 28-959.01, and getting them wrong can mean a citation, a repair order, and in some cases trouble with your insurer.1Arizona Legislature.

Front Side Windows: The 33% Rule
The two windows next to the driver and front passenger, including any wing vents, have to maintain a visible light transmission (VLT) of at least 33%. VLT measures the percentage of outside light that passes through the glass and film together. A lower number means a darker window.1Arizona Legislature. Arizona Code 28-959.01 – Materials on Windows or Windshield; Exceptions; Requirements; Violation; Definitions
The statute allows a plus-or-minus three percent tolerance, so a reading of 30% VLT on a front side window still falls inside the compliant range. That tolerance is a cushion, not a target. Meter readings fluctuate with conditions, and experienced installers usually choose a film rated at 35% VLT so a borderline reading never puts you in violation.
Windshield: Top Strip Only
You can run a tinted strip across the top of the windshield, but the bottom edge of that strip has to sit at least 29 inches above the driver’s seat measured in its lowest and rearmost position. The common shorthand references, the “top five inches” or the AS-1 line, are approximations. The legal standard is the 29-inch measurement from the seat.1Arizona Legislature. Arizona Code 28-959.01 – Materials on Windows or Windshield; Exceptions; Requirements; Violation; Definitions
The strip cannot be red or amber. Clear or lightly shaded films designed to block UV and infrared heat are the standard windshield choice, and some ceramic films reject significant heat while remaining nearly invisible.
Rear Side and Back Windows: No Darkness Limit
Arizona is more permissive here than many drivers expect. Rear side windows and the back window have no VLT limit, regardless of whether you drive a sedan, SUV, or van. Full limo tint is legal on those surfaces. The only cap that applies is reflectance.1Arizona Legislature. Arizona Code 28-959.01 – Materials on Windows or Windshield; Exceptions; Requirements; Violation; Definitions
The frequent claim that sedans have to keep rear windows at 33% VLT is incorrect. The 33% rule applies only to front side windows. The statute makes no distinction between vehicle body styles for rear glass. If a shop tells you a sedan’s rear windows have to stay lighter than an SUV’s, they’re confusing Arizona law with another state’s rules.
Reflectance: 35% on All Side and Back Glass
Reflectance measures how much light bounces off the window’s surface, creating a mirror-like appearance. Highly reflective film can throw glare at other drivers, so Arizona caps it. Front side windows cannot exceed 35% luminous reflectance, and rear side and back windows carry the same 35% limit. Both figures include the same plus-or-minus three percent tolerance as the VLT rules.1Arizona Legislature. Arizona Code 28-959.01 – Materials on Windows or Windshield; Exceptions; Requirements; Violation; Definitions
Reflectance is independent of darkness. A very dark film with low reflectance is legal on rear glass. A lighter film with a shiny, metallic finish can violate the reflectance limit while meeting VLT. Modern ceramic and nano-ceramic films tend to combine low reflectance with strong heat rejection, which is why they’ve largely replaced older metallic films in the Arizona market.
Colors You Can’t Use
Red and amber tint are prohibited on any window, including the windshield strip. Those colors can be mistaken for emergency lighting or create confusion at intersections.1Arizona Legislature. Arizona Code 28-959.01 – Materials on Windows or Windshield; Exceptions; Requirements; Violation; Definitions Neutral, gray, charcoal, and blue-toned films are fine. Most quality automotive films are neutral by default, so this restriction rarely comes up outside of specialty or decorative film.
Medical Exemption for Darker Front Windows
If a medical condition requires extra protection from sunlight, Arizona lets you go darker on front side windows than the standard 33% allows. The process runs through the Arizona Department of Transportation’s Medical Review Program.
You submit a completed Application for Window Tint Medical Exemption (Form 40-1511), certified by a Doctor of Medicine, Doctor of Osteopathic Medicine, Naturopathic Medical Doctor, or Ophthalmologist confirming that you need to be shielded from direct sunlight and that standard eye protection isn’t adequate.2Arizona Department of Transportation. Application for Window Tint Medical Exemption
Once approved, you receive a certificate that has to stay in the vehicle at all times. The certificate is vehicle-specific, so if you own more than one car you need one for each.3Department of Transportation. Medical Review – Section: Window Tinting Exemption If you’re pulled over and can’t produce the certificate, an officer can cite you for non-compliant tint just as if you had no exemption.
What a Tint Violation Costs
A tint violation in Arizona is a civil traffic offense. The statute itself doesn’t set a specific fine, and the amount depends on the court handling the citation. Equipment violation fines in Arizona justice courts generally run in the low hundreds of dollars, with repeat or combined citations pushing the total higher.
The fine often isn’t the worst part. An officer can issue a repair order requiring you to remove or replace the non-compliant film, and ignoring that order triggers an additional violation. Some insurers treat tint citations like any other moving violation on your record, which can lift your premium at renewal. And if you’re in a covered accident with illegal tint, an insurer may refuse to pay for damage to the non-compliant windows.
Picking Film That Handles Arizona Heat
Drivers often reach for the darkest tint available, but darkness and heat rejection aren’t the same thing. A cheap dyed film at 5% VLT blocks almost all visible light but can still let plenty of infrared heat through. A high-end ceramic film at a legal 35% VLT can reject far more heat while keeping your front side windows compliant.
The spec to look for is infrared rejection (IRR) or total solar energy rejected (TSER). Modern nano-ceramic and multi-layer optical films can reject 90% or more of infrared heat even at high VLT. On rear windows, where there’s no darkness cap, pairing high IRR with low VLT gives you maximum heat protection. For front side glass, a ceramic or crystalline film in the 35 to 40% VLT range is the practical sweet spot: compliant with room to spare, low reflectance, and serious heat rejection in desert conditions.
Ask your installer for documentation showing the film’s VLT and reflectance ratings. Keep it with your vehicle records so you have a reference if a traffic stop ever turns into a question about your tint.
