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. 1,2

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. 7,8,9,10
Key Differences in Commercial Auto Insurance
Standalone trucking products beside packaged Business Auto
AIG describes admitted auto liability and physical-damage products for for-hire trucking fleets above 26,000 pounds, with 11–250 power units and at least four years operating. THREE presents Business Auto as a component of its combined Business Owners Policy rather than identifying a separate standalone auto policy. A truck operator should ask whether either structure fits the fleet and whether auto can be purchased independently or appears in the package quote. 3 6
Broker access compared with an online package quote
AIG says select brokers access its trucking offer and describes services such as fleet-safety and DOT-compliance support. THREE directs small-business prospects to an online quote, with licensed Small Business Advisors available to help; its public product page does not state a separate Business Auto limit or deductible. Buyers should compare the proposed declarations and policy terms, because an online package listing does not establish that Business Auto is included for a particular risk. 3 6

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.[1][2]

The inspected sources report separate measures: NerdWallet’s 4.0/5 editorial rating is excluded from the source-rating average; Trustpilot displayed 2.5/5 from five user posts and BBB displayed 4.8/5 from 265 reviews. Trustpilot and BBB include different purchase, service and agent/intermediary interactions, not a verified common policyholder cohort. BBB separately lists complaints. Any source-rating average weights eligible platforms equally and is not a pooled, representative customer-experience estimate or a claims-quality measure.[4][3][1][2]

AIG vs THREE by Berkshire Hathaway: Commercial Auto Insurance: documented features by provider
| Criteria | AIG Truck Insurance Group Commercial Auto | THREE Business Owners Policy |
|---|---|---|
| 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. 3Company-reported. Role in this product is limited to the description on the linked AIG source. | THREE presents Business Auto as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. 6Company-reported. Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant. |
| Issuing Insurer | Confirm in your quote. | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. 5Company-reported. This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy. |
| 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. 3Company-reported. Audience is the segment AIG names on the linked source; this is not an underwriting decision, quote or guarantee of availability. | The reviewed product page does not state separate eligibility rules for Business Auto; the general quote and advisor route is not proof that a particular business qualifies for it. 6,4Not publicly disclosed. Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms. |
| 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. 3Company-reported. AIG’s public product description is not the policy. Actual entitlement depends on the applicable issued form, endorsements and declarations. | THREE's Business Owners Policy page lists Business Auto among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. 6,5Company-reported. Official THREE package marketing for Business Auto. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy. |
| 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. 3Not publicly disclosed. This statement reports only what the linked public source discloses and does not substitute for a quote or issued policy. | The reviewed public product page does not state a separate limit or deductible for Business Auto; THREE says the quote-specific insurance summary lists limits and deductibles. 6,5Not publicly disclosed. No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible. |
| 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. 3Company-reported. The linked page describes company-reported support; specific account services and third-party arrangements must be confirmed. | Confirm in your quote. |
| How to Apply | Confirm in your quote. | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. 4Company-reported. This is the route for the overall THREE product. It does not show whether Business Auto will be offered for a particular business or whether a customer can bind that line without an issued policy. |
