## Research Scope and Use

Use this comparison to evaluate AIG and Harper for Commercial Auto Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

AIG specifies heavy-truck, fleet-size, driver, and tenure criteria. Harper Insurance targets freight and passenger transport operators and describes a single application submitted to markets that write commercial auto. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://www.harperinsure.com/industries/transportation "Transportation Insurance")

## What Is AIG?

AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. [1](https://www.aig.com/investor-relations "Investor Relations") [2](https://www.aig.com/home/risk-solutions/business "Business")

[AIG profile](https://spot.insure/insurance-providers/aig)

## What Is Harper Insurance?

Harper suits hard-to-place businesses such as contractors, care providers, manufacturers and transportation firms; standard small businesses seeking direct quotes should compare online carriers. Its workers’ compensation service helps classify payroll for audits. [4](https://www.harperinsure.com/sms-terms "Text Messaging Terms and Conditions") [5](https://www.harperinsure.com/insurance-insights/harper-45m-funding-announcement "We're Announcing $47M to Build the Insurance Company Every Business Deserves")

## 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. [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://content.naic.org/insurance-topics/auto-insurance "Auto Insurance") [10](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/business-vehicle-insurance "Business Vehicle Insurance") [11](https://nationalgeneral.com/forms_catalog/CA0001_10012013.pdf "Business Auto Coverage Form")

## Key Differences in Commercial Auto Insurance

### Trucking Criteria and Transportation Operations

AIG targets for-hire fleets with trucks over 26,000 pounds, 11–250 power units, predominantly Class A/B CDL drivers, and four years in operation. Harper Insurance names freight carriers, trucking companies, passenger transport, and specialized operators. Harper describes commercial auto liability separately from collision and comprehensive vehicle damage, so an operator should request both parts and check whether its fleet fits AIG’s narrower criteria. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://www.harperinsure.com/industries/transportation "Transportation Insurance")

### Market Access and Proof of Insurance

AIG says access is through select brokers and describes a 24/7 incident-management hotline. Harper says it submits one application to insurers writing transportation risks and can provide proof-of-insurance documents for FMCSA operating-authority requirements. A carrier facing a filing deadline should ask Harper which proof can be issued after binding and confirm AIG’s broker process and incident contact. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [7](https://www.harperinsure.com/ "Harper Homepage")

## What to Confirm in Commercial Auto Insurance Quotes

- Ask AIG to confirm weight, fleet-size, CDL, and operating-history eligibility. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://www.harperinsure.com/industries/transportation "Transportation Insurance")
- Ask Harper how quickly proof of insurance can be issued and which liability and vehicle-damage parts are quoted. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [7](https://www.harperinsure.com/ "Harper Homepage")
- Confirm insurer identity, FMCSA filing needs, limits, and incident reporting process. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://www.harperinsure.com/industries/transportation "Transportation Insurance")

## Offering Details

| Criteria | AIG Truck Insurance Group Commercial Auto | Harper Commercial Auto Insurance |
| --- | --- | --- |
| Role in This Line | AIG describes itself as providing admitted automobile liability and physical-damage insurance to a specifically scoped for-hire trucking segment; the page does not identify the insurer subsidiary for a particular quote. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") (Evidence: Company-reported; scope: Role in this product is limited to the description on the linked AIG source..) | 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](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [7](https://www.harperinsure.com/ "Harper Homepage") (Evidence: Company-reported; scope: Transportation industry page 'Why Harper' section and homepage coverage-list introduction..) |
| Issuing Insurer | Confirm in your quote. | 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](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [7](https://www.harperinsure.com/ "Harper Homepage") (Evidence: Not publicly disclosed; scope: 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 | AIG scopes this commercial-auto offer to small and midsize for-hire trucking companies with heavy vehicles above 26,000 pounds, fleets of 11–250 power units, predominantly Class A/B CDL drivers and at least four years of operating experience. AIG says access is through select brokers. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") (Evidence: Company-reported; scope: Audience is the segment AIG names on the linked source; this is not an underwriting decision, quote or guarantee of availability..) | Harper says its transportation practice, which includes commercial auto liability, covers freight carriers, trucking companies, passenger transport services and specialized transportation operators. [6](https://www.harperinsure.com/industries/transportation "Transportation Insurance") (Evidence: Company-reported; scope: Transportation industry page 'Who this is for' section; general small-business intake elsewhere on the site does not repeat this list..) |
| Coverage Features | AIG lists admitted automobile liability and physical-damage products for the stated for-hire truck segment. It does not publish a buyer’s vehicle schedule, covered causes, territory, or policy endorsements on this page. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") (Evidence: Company-reported; scope: AIG’s public product description is not the policy. Actual entitlement depends on the applicable issued form, endorsements and declarations..) | 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](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [7](https://www.harperinsure.com/ "Harper Homepage") (Evidence: Company-reported; scope: 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 | AIG says liability deductibles may be offered up to $50,000. This is a stated underwriting option, not a standard deductible or limit for a specific policy. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") (Evidence: Not publicly disclosed; scope: This statement reports only what the linked public source discloses and does not substitute for a quote or issued policy..) | 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](https://www.harperinsure.com/ "Harper Homepage") [6](https://www.harperinsure.com/industries/transportation "Transportation Insurance") (Evidence: Not publicly disclosed; scope: Checked the homepage and transportation industry page on 2026-09-23..) |
| Risk Services | AIG describes a broker-facing appetite platform, trucking risk-control consulting, fleet-safety and DOT-compliance support, and a 24/7 incident-management hotline. These services do not expand policy coverage. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") (Evidence: Company-reported; scope: The linked page describes company-reported support; specific account services and third-party arrangements must be confirmed..) | 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. [6](https://www.harperinsure.com/industries/transportation "Transportation Insurance") (Evidence: Company-reported; scope: 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](https://www.harperinsure.com/ "Harper Homepage") [6](https://www.harperinsure.com/industries/transportation "Transportation Insurance") (Evidence: Company-reported; scope: Homepage and transportation industry page quote-intake forms..) |
