## What Is Commercial Auto Insurance?

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. [9](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [10](https://content.naic.org/insurance-topics/auto-insurance "Auto Insurance") [11](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/business-vehicle-insurance "Business Vehicle Insurance") [12](https://nationalgeneral.com/forms_catalog/CA0001_10012013.pdf "Business Auto Coverage Form")

## Key Differences in Commercial Auto Insurance

### What the Coverage Includes

Chubb describes a Commercial Auto Broad Form Endorsement with rented-auto coverage for employees and auto loan or lease gap protection, plus agreed-value treatment for highly valued private passenger vehicles. MMA’s overview identifies commercial auto as an available business line without describing these endorsements. A company with leased vehicles or executives’ high-value cars should ask whether the quote includes these protections or needs separate endorsements. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") [8](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")

### Access and Service

Chubb says buyers can request a business quote online or work through an appointed independent agent or broker. MMA directs organizations to contact an adviser or specialist to discuss placement and does not establish an online flow or timing. Compare the submission route and what vehicle schedules and driver details are needed, then get the policy form and endorsements before binding. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") [8](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")

## What to Confirm in Commercial Auto Insurance Quotes

- Ask Chubb whether the broad-form and high-value vehicle endorsements apply to your vehicles and how agreed value is documented. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance")
- Ask MMA for the proposed forms, endorsement options, and submission details needed for your fleet. [8](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")
- Ask both providers for the proposed insurer, limits, deductibles, and endorsements before binding.
