The short answer
Damage in front of the driver requires a more conservative assessment than an identical chip elsewhere. ROLAGS defines the Driver's Primary Viewing Area as a 12-inch-wide zone centered on the driver that extends from the top to the bottom of the windshield-wiper sweep. Within that zone, the damage must not exceed 1 inch in diameter, the finished pit must not exceed 3/16 inch, and the repair must be at least 4 inches from another repair.
Meeting those measurements does not automatically make repair appropriate. Resin can improve clarity, but a residual blemish, refraction or light scatter may remain. ROLAGS calls for the finished repair to be inspected from the driver's seated position and recommends replacement if the technician believes the repair would affect proper vehicle operation. Visibility should be assessed under realistic conditions, including direct sun, shadows and nighttime headlights. Arizona law also protects the driver's clear view through the windshield.
