## Research Scope and Use

Use this comparison to evaluate AIG and Liberty Mutual 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.

## Summary

AIG specifies truck weight, fleet size, driver class, and operating history for its for-hire offer. Liberty Mutual describes liability, physical damage, bodily injury, and uninsured-motorist coverage, tailored to fleet and vehicle use. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet")

## 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 Liberty Mutual Business Insurance?

Liberty Mutual spans small-commercial, commercial, specialty, surety, and reinsurance businesses. The insurer and distribution route depend on the product, so check the offer and policy before you compare terms.

## 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

### A Narrow Trucking Appetite and Tailored Auto Programs

AIG describes a for-hire trucking segment with vehicles above 26,000 pounds, 11–250 power units, predominantly Class A/B CDL drivers, and at least four operating years. Liberty Mutual says its underwriters tailor commercial-auto solutions based on industry, fleet, location, and vehicle use. For businesses outside AIG’s stated fleet range, ask Liberty Mutual how its underwriting considers the actual operation and driver mix. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet")

### Coverage Categories to Compare

Liberty Mutual names liability, physical damage, bodily injury, and uninsured-motorist coverages, while stating policy terms control actual protection. AIG lists admitted liability and physical-damage products but does not publish the quote’s vehicle schedule or covered causes. Ask both providers to identify the policy forms and whether hired, borrowed, or non-owned vehicles need separate treatment. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet")

## What to Confirm in Commercial Auto Insurance Quotes

- Ask Liberty Mutual which coverages and limits fit your fleet and location. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet")
- Ask AIG to confirm the program’s vehicle-weight, power-unit, CDL, and tenure rules. [3](https://www.aig.com/home/risk-solutions/business/casualty/truck-insurance-group "Truck Insurance Group") [6](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet")
- Compare vehicle schedules, uninsured-motorist treatment, physical-damage deductibles, and exclusions.

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.
