CNA describes vehicle categories and liability, while THREE lists Business Auto as a component of its combined Business Owners Policy. ## Research Scope and Use Use this comparison to evaluate CNA and THREE by Berkshire Hathaway for Commercial Auto Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote. ## Summary CNA states liability for owned, hired and non-owned business vehicles and offers physical damage. THREE presents Business Auto within its combined BOP and supplies line limits in a quote-specific summary. [4](https://www.cna.com/products/commercial-auto "Commercial Auto Insurance for Businesses | CNA Insurance") [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") ## CNA Small Business Insurance: Products, Agents and Service CNA directs small-business buyers to independent agents and describes CNA Connect as a businessowners policy for more than 600 small-business classes. Issuer and availability vary by policy and state, so confirm both in a quote. [1](https://www.cna.com/solutions/small-business "Insurance for Small Businesses") [2](https://www.cna.com/products/cna-connect "CNA Connect Small Businessowners Policy (BOP) | CNA Insurance") [3](https://www.cna.com/cnadisclaimer/generaldisclaimer "General Disclaimer") [CNA profile](https://spot.insure/insurance-providers/cna) ## THREE small business insurance: coverage, issuer and buying routes THREE markets a packaged commercial insurance product through a direct quote route and partner agents. Berkshire Hathaway Direct Insurance Company is named as issuer on THREE’s sample policy. [5](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") [THREE by Berkshire Hathaway profile](https://spot.insure/insurance-providers/three) ## 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. [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 ### Standalone Detail or Combined Package CNA's commercial-auto record states liability coverage for owned, hired and non-owned business vehicles and separately lists automobile physical damage. THREE presents Business Auto as one part of its combined Business Owners Policy rather than as a standalone product in the reviewed overview. A buyer seeking auto alongside other small-business protections can explore THREE's package route; CNA's record provides more detail on vehicle scope.

CNA names Driver Distractions and Cargo Securement programs with claims support. Compare the package schedule against the vehicle exposures you need and ask CNA about the available prevention resources.

[7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") - Ask CNA about covered hired/non-owned vehicles and endorsements.
