Dust walls on I-10, flooded interchanges on I-17, and heat that finishes batteries early. Phoenix driving puts different pressure on a policy than a mountain highway does.
Arizona's required minimum is 25/50/15. On Valley traffic that is a low ceiling.
Three exposures that are ordinary here and rare almost everywhere else.
In the August 2025 haboob, visibility on I-10 fell to dozens of feet. The advice from the National Weather Service is to pull well off the road, stop, and turn your lights off so nobody follows them into you. Collisions out of blowing dust usually involve several vehicles, which is where liability limits and uninsured motorist cover both get tested at once.
Depressed interchanges fill faster than the pumps drain them, and stretches of I-17 have closed outright in monsoon storms. A flooded car is a comprehensive claim, not collision, and a car driven into standing water is an argument you would rather not be having with an adjuster.
The state minimum is 25/50/15. One multi-vehicle collision on a Valley freeway can pass that before anybody is treated. What sits above the minimum is the part of the policy that decides whether a bad morning becomes a bad decade.
The parts that are easy to leave on default and expensive to leave there.
Carriers must offer both in Arizona and you may reject them in writing. On roads this busy, rejecting them is a decision worth making deliberately rather than by signature.
An insurer offering comprehensive in Arizona must also offer glass replacement with no deductible, but you have to elect it. Between gravel and dust-blasted windshields, it pays for itself here faster than most options.
Hail, blowing dust, flood water and theft are all comprehensive perils. Dropping comprehensive to save a little is the most common false economy we see on Valley policies.

An agent prices it across carriers and calls with the comparison.
