What Are the Key Differences Between Aon and Zurich U.S. Commercial Auto Insurance?

Different Placement Audiences

Aon places Automobile Liability within a practice aimed at law, accounting, and consulting firms. Zurich's reviewed auto offering is specifically for rental fleets and describes fleet-size, vehicle, and rental-use information in its application. A professional-services company should verify that Zurich's rental-fleet scope applies before comparing it with Aon's broader brokerage listing. [1] [6]

Liability and Vehicle Damage

Zurich identifies state financial-responsibility liability and uninsured/underinsured motorist and no-fault personal-injury options for rental fleets, plus specified-peril, comprehensive, and collision physical damage. Aon only lists Automobile Liability and does not provide these details in its record; ask Aon for its proposed forms and scheduled vehicle protection. [6] [1]

Zurich’s Catastrophic Option

Zurich says its catastrophic physical-damage option requires an occurrence involving at least two insured autos and excludes collision, overturn, and conversion. Aon's record does not describe an equivalent auto option, so ask whether its proposal covers fleet-wide events and how each policy treats a single-vehicle loss. [6] [1]
