What Are the Key Differences Between AIG and Aon Commercial Auto Insurance?

Trucking Fleet Criteria and Professional-Service Audience

AIG’s program targets for-hire trucking firms with trucks over 26,000 pounds, 11–250 power units, predominantly Class A/B CDL drivers, and at least four years of operations. Aon’s professional-services practice identifies law, accounting, and consulting firms as its audience and lists automobile liability as a line it helps arrange. A trucking operator should check AIG’s specific thresholds; a professional firm should ask Aon which carrier and form fit its vehicle use. [1] [2]

Insured Vehicles and Risk Advice

AIG lists automobile liability and physical damage for its trucking segment. Aon’s page does not describe covered autos, drivers, or liability limits, and its role is brokerage and advice rather than underwriting. For either route, provide vehicle and driver schedules and request the insurer’s actual declarations; AIG also says access is through select brokers. [1] [2]

What Should You Confirm in AIG and Aon Commercial Auto Insurance Quotes?

  • Ask AIG to verify power-unit count, vehicle weight, CDL mix, and operating history. [1] [2]
  • Ask Aon who would issue and place the policy for the firm’s vehicles and what limits apply. [1] [2]
  • Confirm whether physical damage, hired vehicles, and employee-owned autos are included. [1] [2]

AIG names heavy-truck, fleet-size, driver, and experience criteria for its trucking offer. Aon lists automobile liability for professional-service firms through its brokerage and advisory practice, without publishing auto schedules or limits.
