What Are the Key Differences Between AIG and Liberty Mutual 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. [1] [5]

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. [1] [5]

  • Ask Liberty Mutual which coverages and limits fit your fleet and location. [1] [5]
  • Ask AIG to confirm the program’s vehicle-weight, power-unit, CDL, and tenure rules. [1] [5]
  • Compare vehicle schedules, uninsured-motorist treatment, physical-damage deductibles, and exclusions. [1] [5]
