Key Differences in Commercial Auto Insurance

Coverage and Fleet Use

THREE presents Business Auto as part of a combined Business Owners Policy rather than a standalone policy on the reviewed page. MMA describes commercial auto as a business coverage placement but does not specify whether it is packaged with a BOP. 3 6

How Buyers Reach the Market

THREE offers an online quote route with licensed Small Business Advisors; MMA invites contact with an adviser or specialist. A buyer seeking bundled small-business insurance should compare the full package, while a company needing a standalone fleet policy should confirm whether the selected product permits it. 3 6

What to Confirm in Commercial Auto Insurance Quotes

  • Ask THREE whether Business Auto appears in your BOP quote and review the sample-policy wording and issuing insurer. 6
  • Ask MMA whether auto is standalone or bundled in the proposed program and who issues the policy. 3
  • Ask both providers which insurer issues the policy and how newly added vehicles or drivers are reported. 3 6
