What Are the Key Differences Between AIG and Marsh McLennan Agency 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. [1] [5]

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. [1] [5]

What Should You Confirm in AIG and Marsh McLennan Agency Commercial Auto Insurance Quotes?

  • Ask AIG whether the fleet matches its published vehicle, driver, and operating-history requirements. [1] [5]
  • Ask MMA which carrier and vehicle-use details its adviser needs before proposing terms. [1] [5]
  • Confirm claims contacts, physical damage, hired/non-owned autos, and certificate timing. [1] [5]

AIG specifies heavy-truck fleet and driver criteria with a 24/7 incident hotline. Marsh McLennan Agency describes adviser-led commercial-auto placement based on business operations and loss exposures.
