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 6
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 6
