On average the cost of a windshield replacement in Arizona ranges between $150 to $700, including the cost of labor. However, as mentioned, it will vary on the make and model of your vehicle, as well as any special features you have on your windshield.

Comprehensive auto glass coverage on a car insurance policy may help pay to repair or replace your windshield if it's cracked or shattered by a rock. Another coverage, called full glass coverage, may also be available to help protect you against the cost of fixing or replacing a windshield.

Arizona does not have any specific law that makes it illegal if your glass has minor cracks and chips in it. All the state wants is for you to have nothing obstructing your view while driving.
