Arizona Commercial Auto Insurance

Arizona's Minimum Liability Requirements

Arizona's standard financial responsibility law sets a minimum liability requirement of $25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage — commonly written as 25/50/15 — under A.R.S. §28-4009 (Arizona Department of Transportation).

Heavier commercial vehicles carry higher statutory minimums under A.R.S. §28-4033: vehicles between 20,001 and 26,000 lbs GVWR hauling nonhazardous property need a $300,000 combined single limit, vehicles over 26,000 lbs need $750,000, and hazardous materials haulers need between $1,000,000 and $5,000,000 depending on the substance. Vehicles carrying passengers for hire face their own tiered minimums — $250,000 for 8 or fewer passengers, $750,000 for 9-15, and $5,000,000 for 16 or more (Arizona Legislature, Insurance.com).

What Commercial Auto Insurance Covers

Commercial auto liability covers bodily injury and property damage your business vehicles cause to others. Physical damage coverage (collision and comprehensive) protects your own vehicles from accidents, theft, weather, and vandalism. Businesses with any vehicle used for work — from a single service van to a small delivery fleet — need a commercial policy rather than a personal auto policy, which typically excludes business use.

Common Questions

Frequently Asked Questions

Can I use my personal auto policy for a work vehicle?

Generally no. Personal auto policies typically exclude business use, and a claim involving a work vehicle on a personal policy can be denied. A commercial auto policy is built for that exposure.

Do higher-weight trucks need more than the standard 25/50/15?

Yes — under A.R.S. §28-4033, vehicles over certain GVWR thresholds carry statutory minimums well above the standard limit, scaling up based on weight and cargo type.

What if employees drive their own vehicles for work errands?

Hired and non-owned auto coverage extends your liability protection to those situations, which a personal auto policy generally won't cover for business use.
