[4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") [8](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [7](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")

## 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

### Standalone option and policy enhancements

Chubb underwrites commercial auto directly and sells it either standalone or through its Total Account Solution alongside a BOP. Its revised multi-state forms include a broad-form endorsement with enhancements such as rented-auto coverage for employees and auto loan or lease gap coverage; high-value vehicles can use an agreed-value endorsement. THREE lists Business Auto among the categories in its combined BOP but does not say whether it can be purchased separately or name similar endorsements. Ask for the specific forms and vehicle schedule before comparing the offerings. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") [8](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### Risk services and published limits

Chubb describes outside risk-management consulting and fleet-safety materials; when bundled through its small-business Total Account Solution, it publishes personal-injury-protection and uninsured/underinsured motorist limits up to $1 million. Its standalone page does not publish limits. THREE’s reviewed record likewise does not state commercial-auto limits or fleet services and offers an online quote with advisor support. Match the quote route to the limits shown on each declaration, including any state-specific restrictions. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") [5](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business") [6](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway")

## What to Confirm in Commercial Auto Insurance Quotes

- Ask Chubb whether coverage is standalone or bundled and whether the $1 million limits apply to your chosen package. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") [5](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business")
- Ask THREE for vehicle schedules, liability limits, and any available fleet-risk services. [8](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")
- Compare endorsements for rented vehicles, loan gaps, and hired/non-owned autos. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") [8](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

[8](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant..) |
| Issuing Insurer | Confirm in your quote. | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. [7](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy..) |
| Who It’s For | Chubb lists the industries it serves for commercial auto, including manufacturing, climate tech, natural resources, financial services, professional services, technology, life sciences, media and entertainment, federal contractors, oil and gas, and wholesalers/distributors.

[4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") (Evidence: Company-reported; scope: Commercial Auto product page coverage-highlights list; availability depends on the issued policy and state..) | THREE's Business Owners Policy page lists Business Auto among its marketed coverage categories in the combined policy.

[6](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the route for the overall THREE product. It does not show whether Business Auto will be offered for a particular business or whether a customer can bind that line without an issued policy..) |
