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. 6 3
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. 6 3

Aon vs Harper: Commercial Auto Insurance: documented features by provider
| Criteria | Aon Automobile Liability brokerage and risk-advisory offering | Harper Commercial Auto Insurance |
|---|---|---|
| Role in This Line | Aon presents Automobile Liability as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. 3Company-reported. Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement. | 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. 6,7Company-reported. Transportation industry page 'Why Harper' section and homepage coverage-list introduction. |
| Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. 3Not found in reviewed sources. Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement. | The reviewed pages do not name the insurer or insurers that would issue a commercial auto policy Harper places; the transportation page describes 'every market' generally without listing carriers. 6,7Not publicly disclosed. Checked the transportation industry page and homepage insurer-logo panel on 2026-09-23; no carrier names found for commercial auto specifically. |
| Who It’s For | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. 3Company-reported. Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement. | Harper says its transportation practice, which includes commercial auto liability, covers freight carriers, trucking companies, passenger transport services and specialized transportation operators. 6Company-reported. Transportation industry page 'Who this is for' section; general small-business intake elsewhere on the site does not repeat this list. |
| Coverage Features | Aon lists Automobile Liability in its property-and-casualty offerings for professional services firms. The page does not describe covered autos, drivers, liability limits or policy terms. 3Company-reported. Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to 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. 6,7Company-reported. Transportation industry page coverage callouts; the homepage separately describes commercial auto with 'coverage limits your contracts accept' rather than published limit amounts. |
| Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. 3Not publicly disclosed. Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed. | 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. 7,6Not publicly disclosed. Checked the homepage and transportation industry page on 2026-09-23. |
| Risk Services | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. 3Company-reported. Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated. | Harper says it delivers proof-of-insurance documents quickly to support FMCSA operating-authority requirements, and describes explaining commercial auto, cargo coverage and FMCSA requirements in plain terms. 6Company-reported. Transportation industry page 'Why Harper' section. |
| How to Apply | Confirm in your quote. | You can request a commercial auto quote through Harper's online intake by selecting the 'Work vehicles (commercial auto)' checkbox, or by using the transportation-specific intake form, along with the business's state and estimated annual revenue. 7,6Company-reported.
