What Commercial Auto Insurance Requirements Apply in Arizona?

What Is Commercial Auto Insurance?

Commercial auto suits businesses that use vehicles for work and need liability protection; damage to your own vehicles is a separate coverage choice. If employees drive personal or rented cars, check how those trips are handled. Read the national Commercial auto guide.

Arizona Commercial Auto Insurance Requirements

What Should You Watch for With Commercial Auto Insurance in Arizona?

• Check Whether Article 28-4033 Covers Your Operation

  Arizona applies its higher transportation limits to people subject to Article 2, whose scope is defined separately from the general 25/50/15 motor-vehicle floor. Ask the broker to identify the legal basis for your fleet’s limit instead of assuming every business vehicle uses either one schedule. ^1,2,3

• Freight Limits Change At The 26,000-Pound Line

  For covered nonhazardous property transport, § 28-4033 sets $300,000 at 20,001–26,000 pounds gross vehicle weight and $750,000 above 26,000 pounds. Check each vehicle’s rated weight with any regular combination before selecting the limit. ³

• Hazardous-Cargo Limits Turn On Material And Handling

  Arizona requires $5 million for specified high-risk materials and transport methods, and $1 million for other listed hazardous materials under the statute. Give the broker the exact commodity, packaging, and vehicle details so the required category is identified correctly. ³

• Large Passenger Vehicles Have A Separate Limit

  A vehicle with seating capacity of 16 or more falls under a $5 million liability requirement and must carry at least $300,000 in uninsured-motorist coverage under § 28-4033. If passenger capacity is part of your operation, include it in the limit review. ³

Which Providers Have Documented Arizona Licenses?

These providers publish a national listing for Commercial auto; the state records document licenses for the entities and roles shown below. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Arizona. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

• Corgi

  Corgi Insurance Services, Inc.

  Insurance producer · checked 2026-09-28

  Corgi’s company producer-license table lists 50 jurisdictions: 49 states and the District of Columbia, including DC license 3003091619. New Mexico does not appear in the table and is not included here; the omission does not establish that Corgi is unlicensed there. The company-reported table has no stated as-of date and does not establish product availability. ¹⁵

  Corgi links to trucking auto-liability coverage from its transportation menu.

• TechInsurance

  Specialty Program Group LLC

  Insurance producer · checked 2026-09-28

  TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ¹⁹

  TechInsurance arranges commercial auto insurance for small businesses.

Surplus-Lines Tax and Stamping Office in Arizona

Reported tax rate. 3% of gross premium and taxable policy fees, less returns; stamping fee rate not verified ^7,9,11,12

When Arizona is the insured’s home state, the tax is 3% of gross premium and taxable policy fees, less returned premium; the statute excludes stamping fees from that tax base. For a multistate risk, Arizona’s share is allocated by exposure under the statute. Arizona's surplus-lines policy notice says these policies do not receive guaranty-fund protection. Current stamping-fee amount was not independently confirmed from readable current evidence and is omitted.

The Surplus Line Association of Arizona

• Arizona has an exempt-commercial-purchaser search exception: A surplus-lines broker generally must make diligent effort to place an Arizona risk in the admitted market. For an exempt commercial purchaser, federal law removes that search only after the broker discloses the admitted-market protection difference and the purchaser then asks in writing for nonadmitted coverage. ^8,10
