Arizona statute requires insurers to make no-deductible glass coverage available. The obligation is to offer it. Whether a given policy carries it is a separate question.
A.R.S. § 20-264(A) applies to any insurer writing private passenger automobile insurance that includes comprehensive coverage for motor vehicle damage. Those insurers must provide, at the option of the insured, complete coverage for the repair or replacement of all damaged safety equipment without regard to any deductible. Subsection (B) defines safety equipment as the glass used in the windshield, doors and windows, plus the glass, plastic or other material used in the lights.
The phrase doing the work is "at the option of the insured". The statute sets what an insurer has to make available, and nothing more. It gets called a free windshield law. The text doesn't say that, and what any particular policy covers is a question for the insurer or the agent who wrote it.
A.R.S. § 28-957.01 requires an adequate windshield on passenger vehicles, motor trucks and truck tractors, with exceptions that include implements of husbandry and fully autonomous vehicles. The statute never defines adequate. No crack length, no chip count.
The section that reaches a replacement job is A.R.S. § 28-959(D), which bars replacing glass or glazing material in a motor vehicle with anything other than safety glass. Subsection (E) defines safety glass as a product manufactured, fabricated or treated so that it substantially prevents shattering and flying of the glass when struck or broken, and that meets applicable federal safety standards. Subsection (A), the one that ties safety glass to sale and registration, applies to new vehicles.
The Arizona Registrar of Contractors licenses glazing under R-65, C-65 and the dual CR-65. All three cover buildings: glass products, window film, window treatments, and the steel and aluminum members that hold glass. None extends to vehicles.
