Arizona’s windshield law requires every passenger car and truck to have an adequate windshield made of safety glass, and prohibits any damage, tint, or material that blocks the driver’s clear view through the windshield or any window. The rules sit in Title 28 of the Arizona Revised Statutes, and they interact with a separate insurance statute that lets you carry glass coverage with no deductible.
The Core Rule: Adequate and Unobstructed
Two statutes do the work. ARS 28-957.01 requires passenger vehicles and trucks to have an “adequate windshield,” without defining the word.1Arizona Legislature. Arizona Revised Statutes Title 28 – Section 28-957.01 – Windshields Required; Exceptions That leaves officers with discretion. A small chip near the edge often draws no attention. A spiderweb crack across the driver’s sightline almost always does.
ARS 28-959.01(B) is the provision with teeth. It prohibits operating a vehicle with any object or material on the windshield, side windows, or rear windows that “obstructs or reduces a driver’s clear view.”2Arizona Legislature. Arizona Revised Statutes Title 28 – Section 28-959.01 – Materials on Windows or Windshield; Exceptions The same language covers aftermarket tint, stickers, and accumulated damage. If damage meaningfully cuts into visibility, an officer can cite you without pulling out a ruler.
What You Can Legally Place on the Glass
The statute carves out a short list of permitted items:
- A sticker within a seven-inch square in the lower passenger-side corner of the windshield.
- A sticker within a five-inch square in the lower driver-side corner.
- A transparent sun-strip along the top of the windshield, with its bottom edge at least 29 inches above the driver’s seat measured in its lowest position.
- Dashcams and safety monitoring equipment mounted near the rearview mirror.2Arizona Legislature. Arizona Revised Statutes Title 28 – Section 28-959.01 – Materials on Windows or Windshield; Exceptions
Anything outside those carve-outs is subject to the general obstruction ban.
Window Tint Limits
Arizona’s tint rules are structured as exemptions from the obstruction ban. Tint that falls within the exempted ranges is legal; tint outside them violates ARS 28-959.01.
Front Side Windows
Front side windows and wing vents are exempt when the film allows at least 33 percent of light through (plus or minus 3 percent) and luminous reflectance stays at 35 percent or below (plus or minus 3 percent).2Arizona Legislature. Arizona Revised Statutes Title 28 – Section 28-959.01 – Materials on Windows or Windshield; Exceptions Most drivers aim slightly above 33 percent to stay clear of the tolerance edge. Heavily mirrored or metallic films that exceed the 35 percent reflectance ceiling are not permitted.
Rear Side Windows and Back Windshield
Rear side windows and the back windshield have no minimum light-transmission floor. They can be as dark as you want, up to full blackout, provided reflectance stays at or below 35 percent. If the rear window is tinted, the vehicle must have outside mirrors on both sides that give the driver a view of at least 200 feet to the rear.2Arizona Legislature. Arizona Revised Statutes Title 28 – Section 28-959.01 – Materials on Windows or Windshield; Exceptions
Windshield
Tint film on the windshield itself is limited to a transparent strip along the top. Its bottom edge must sit at least 29 inches above the driver’s seat, measured with the seat in its lowest and rearmost position. The strip cannot be red or amber, colors that could be mistaken for emergency lighting. Below the strip, the windshield must stay clear factory glass.2Arizona Legislature. Arizona Revised Statutes Title 28 – Section 28-959.01 – Materials on Windows or Windshield; Exceptions
Medical Exemption for Darker Tint
Arizona allows darker-than-normal tint on side and rear windows for drivers with medical conditions requiring protection from direct sunlight. The exemption is authorized under ARS 28-959.01(G) and administered by the Motor Vehicle Division through Form 40-1511.3Arizona Department of Transportation. Application for Window Tint Medical Exemption – Form 40-1511 Lupus, albinism, and severe photosensitivity are typical qualifying diagnoses, but the form doesn’t restrict it to a set list. Any condition where eye-protective devices alone provide inadequate protection can qualify.
The application requires certification from a licensed MD, DO, NMD, or ophthalmologist. Submit the completed form and vehicle information to MVD by mail or email. Once approved, the exemption covers the driver-side, passenger-side, and rear windows only. It does not permit additional tint below the AS-1 line on the windshield. Vehicles can be added to an existing exemption without a new physician signature.
Safety Glass and Registration
Every piece of glass in a vehicle’s doors, windows, and windshield must be safety glass, meaning the laminated or tempered type that resists shattering into dangerous shards. ARS 28-959 defines it as glass “manufactured, fabricated or treated in a manner that substantially prevents shattering and flying of the glass when struck or broken” and that meets federal standards.4Arizona Legislature. Arizona Revised Statutes Title 28 – Section 28-959 – Safety Glass Required; Applicability; Denial or Suspension of Registration; Definition
Compliance is tied to registration. ADOT can refuse to register a new vehicle without approved safety glass, and can suspend the registration of any vehicle later found without it. Replacement glass must meet the same standard. If a shop installs non-safety glazing, both the shop and the vehicle owner face potential violations.
Replacement glass comes in two forms. OEM (Original Equipment Manufacturer) glass is made by the same company that produced the original, to identical specifications. Aftermarket glass, sometimes labeled OEE, is made by a different manufacturer to similar specifications, with possible small variations in thickness, curvature, or fit. Either type is legal in Arizona as long as it meets the safety-glass standard.
Camera Recalibration After a Windshield Replacement
Most vehicles built in the last decade carry a forward-facing camera mounted to the windshield. It powers lane-departure warnings, automatic emergency braking, and adaptive cruise control. When the windshield is replaced, that camera must be recalibrated. The new glass acts as a second lens, and small differences in the glass or mounting position throw off the system’s aim.
The stakes are concrete. If camera alignment is off by one degree, a collision-avoidance system will misread objects by roughly eight feet at a distance of 100 feet. At 30 miles per hour, a vehicle needs about 89 feet to stop on dry pavement, so an uncalibrated system might not trigger braking until past the point of impact. No dashboard warning appears. The system looks fine until it fails.
Recalibration is done statically (indoors, with manufacturer targets at set distances and a diagnostic tool), dynamically (driving at specific speeds on well-marked roads while the system self-adjusts), or both in sequence. The process takes 30 minutes to several hours and typically costs between $600 and $1,100 depending on the vehicle. No current vehicle can recalibrate itself after a windshield swap. If a shop tells you the car will “figure it out” while you drive, that is wrong, and skipping the step leaves the shop liable regardless of any waiver you sign.
Insurance: The No-Deductible Option
Arizona has one of the more driver-friendly glass insurance rules in the country. Under ARS 20-264, any insurer writing comprehensive auto coverage must offer the policyholder the option of full glass repair or replacement with no deductible. The statute’s definition of “safety equipment” includes all glass in the windshield, doors, and windows, plus light covers.5Arizona Legislature. Arizona Revised Statutes Title 20 – Section 20-264 – Automobile Insurance; Damaged Safety Equipment Deductible Optional; Definition
The key word is “option.” Insurers must offer it. You are not required to buy it. Drivers who skip the coverage pay out of pocket for replacements that can run $250 to $800 on a standard passenger vehicle and considerably more on luxury cars or vehicles with advanced safety systems.
When you file a glass claim, you choose the shop. Arizona Administrative Code R20-6-801 prohibits insurers from forcing you to use a specific shop or travel unreasonably far for repairs.6Cornell Law School Legal Information Institute. Arizona Administrative Code R20-6-801 – Unfair Claims Settlement Practices Insurers may suggest preferred vendors, and many route glass claims through third-party administrators that sometimes steer callers toward affiliated shops, but the final choice is yours.
Penalties
Windshield and tint violations are civil traffic offenses. Common violations, including operating without an adequate windshield, using non-approved glass, or having improper materials on windows, carry a base fine around $80 in many Arizona courts. Mandatory surcharges and assessments raise the total, and the total varies by court. For tint violations specifically, fines can reach $250.
Officers often handle windshield-damage citations as fix-it tickets: repair or replace the glass, bring proof of compliance to the court, and the fine may be reduced or dismissed. That outcome is at the officer’s discretion, not guaranteed. Repeat tint violations are treated less leniently, and an officer can require removal of non-compliant film. Because ARS 28-959 ties safety-glass compliance to vehicle registration status, ongoing equipment violations can eventually create registration problems as well.4Arizona Legislature.

Arizona’s heat is its own enforcement mechanism. A small chip that would cost around $50 in resin repair can spread into a full crack, and a $400-plus replacement, within a week of desert summer driving. Fix it early and the compliance question rarely comes up.
