What Are the Key Differences Between Aon and Harper Commercial Auto Insurance?

Liability and Vehicle Damage

Harper separates commercial-auto liability for transport accidents and third-party injury from physical damage for collision and comprehensive losses to the business’s own vehicles. Aon’s reviewed page lists Automobile Liability for professional-services firms but does not specify vehicle damage. A trucking or passenger-transport operator should ask Harper how the separate coverages coordinate, and ask Aon whether its proposed form addresses the scheduled vehicles and uses. [4] [1]

Operating Authority and Intake

Harper says it can deliver proof-of-insurance documents to support FMCSA operating-authority requirements and describes commercial auto for transportation operations. Aon names law, accounting, and consulting firms for its Professional Services Practice. A carrier with a launch date should ask Harper which filing and certificate recipient it will support, and ask Aon whether it can submit the same operation; Harper’s service description does not guarantee an issued certificate.

Harper

  • role: Harper describes itself as taking one application for a transportation business and calling the insurance companies that write commercial auto for that kind of operation, rather than underwriting the policy itself.

  • eligibility: Harper says its transportation practice, which includes commercial auto liability, covers freight carriers, trucking companies, passenger transport services and specialized transportation operators. Transportation industry page 'Who this is for' section; general small-business intake elsewhere on the site does not repeat this list.company-reportedSource ↗
  • coverage: Harper describes commercial auto liability as coverage for vehicle accidents and third-party injuries during transportation operations, alongside a separate physical-damage coverage for collision and comprehensive damage to the vehicles themselves. Transportation industry page coverage callouts; the homepage separately describes commercial auto with 'coverage limits your contracts accept' rather than published limit amounts.company-reportedSource ↗Source ↗

  • limits: Harper's reviewed pages do not publish commercial auto liability or physical-damage limits and deductibles; the homepage says only that coverage comes with 'limits your contracts accept,' meaning the buyer's own contracts, not a published Harper figure, set the target.
