Marsh McLennan Agency provides business insurance and employee health and benefits, alongside retirement, wealth, and private-client services across the United States and Canada. Its US small-business page lists six common coverage types and directs buyers to request a personalized quote by phone; the insurer and terms for a specific placement must be confirmed in the proposal.

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. [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://content.naic.org/insurance-topics/auto-insurance "Auto Insurance") [10](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/business-vehicle-insurance "Business Vehicle Insurance") [11](https://nationalgeneral.com/forms_catalog/CA0001_10012013.pdf "Business Auto Coverage Form") ## Key Differences in Commercial Auto Insurance ### Industry and Account Review The Baldwin Group names transportation operators and government contractors as audiences for commercial auto liability. Marsh McLennan Agency (MMA) describes a broader business-insurance placement and says advisers analyze an organization’s operations, assets, liabilities and loss exposures. This means the two records set different context: Baldwin highlights transport and contract work, while MMA describes an organization-wide review. Neither audience guarantees eligibility or specifies auto policy terms. If vehicles support a government contract or are part of a wider company program, ask both advisers how they assess those exposures and whether the auto policy is coordinated with other lines. [4](https://baldwin.com/business-insurance/industries/transportation/ "Transportation Insurance & Risk Management") [7](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA") ### Adviser Route and Policy Terms MMA invites buyers to contact an adviser or specialist but does not establish a quote or bind timeline. Baldwin similarly describes a broker-advisory relationship without naming the insurer for a specific placement. Neither summary publishes limits, deductibles or covered vehicle schedules. Compare the actual carrier proposal, especially liability limits, physical damage and hired/non-owned coverage, rather than the breadth of either firm’s advisory language. [4](https://baldwin.com/business-insurance/industries/transportation/ "Transportation Insurance & Risk Management") [7](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA") ## What to Confirm in Commercial Auto Insurance Quotes - Ask Baldwin which carrier will quote your fleet and what vehicle, contract and state details it needs. [4](https://baldwin.com/business-insurance/industries/transportation/ "Transportation Insurance & Risk Management") - Ask MMA which adviser will handle the commercial auto placement and request the insurer and policy terms.

The reviewed public sources do not establish a representative customer rating for The Baldwin Group’s commercial advisory business. BBB pages show different legal entities: an A+ regional insurance-agency grade with zero listed reviews and complaints for The Baldwin Group Mid-Atlantic, LLC, and an A- grade plus six complaints in three years for The Baldwin Group Personal Insurance, LLC. A 2026 personal-lines complaint describes delayed refund handling. A separate National General auto review mentions a Baldwin referral but concerns insurer policy administration.
