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

## Key Differences in Commercial Auto Insurance

### Truck Criteria and Adviser-Led Placement

AIG targets established for-hire trucking firms with vehicles above 26,000 pounds, fleets of 11–250 units, predominantly Class A/B CDL drivers, and at least four years in operation. Marsh McLennan Agency (MMA) describes commercial-auto placement through advisers who analyze operations, assets, liabilities, and loss exposures, but its overview does not state detailed policy terms. A company should use the analysis to frame its submission, then ask MMA which insurer and form match its fleet. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")

### Operational Risk and Coverage Questions

AIG describes a risk-control platform and trucking support services. MMA invites organizations to speak with an adviser or specialist, but does not state an online quote or bind timeline. If a fleet must satisfy a contract deadline, ask MMA what documents are needed and request the proposed limits and evidence-of-insurance timing; confirm AIG’s select-broker route as well. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")

## What to Confirm in Commercial Auto Insurance Quotes

- Ask AIG whether the fleet matches its published vehicle, driver, and operating-history requirements. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")
- Ask MMA which carrier and vehicle-use details its adviser needs before proposing terms. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")
- Confirm claims contacts, physical damage, hired/non-owned autos, and certificate timing. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")

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.
