[3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](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. [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

### Transportation focus and vehicle damage

Harper’s transportation practice serves freight carriers, trucking companies, passenger transport, and specialized operators. It distinguishes liability for vehicle accidents and third-party injuries from physical-damage coverage for collision and comprehensive damage to vehicles. THREE lists Business Auto within its combined BOP but does not identify trucking classes or explain physical-damage options in the reviewed offering. A carrier should ask Harper about transport fit and ask THREE whether its package extends to fleets and required filings. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### Operating-authority documents

Harper says it can deliver proof-of-insurance documents quickly for FMCSA operating-authority requirements and explains auto, cargo, and FMCSA rules. THREE’s reviewed Business Auto description does not mention transportation filings or cargo. For a regulated carrier, document timing can affect when operations begin; confirm the named insured, filing responsibility, and delivery with each quote. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [5](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway")

## What to Confirm in Commercial Auto Insurance Quotes

- Ask Harper which liability and physical-damage options satisfy your FMCSA obligations. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance")
- Ask THREE whether Business Auto is available for transportation operators and supports required filings. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")
- Confirm who files proof of insurance and whether cargo is separate. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance")

## Offering Details

| Criteria | Harper Commercial Auto Insurance | THREE Business Owners Policy |
| --- | --- | --- |
| Role in This Line | Harper describes itself as taking one application for a transportation business and calling the insurance companies that write commercial auto for that kind of operation, rather than underwriting the policy itself. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [4](https://www.harperinsure.com/ "Harper Homepage") (Evidence: Company-reported; scope: Transportation industry page 'Why Harper' section and homepage coverage-list introduction..) | THREE presents Business Auto as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. [7](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 | The reviewed pages do not name the insurer or insurers that would issue a commercial auto policy Harper places; the transportation page describes 'every market' generally without listing carriers. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [4](https://www.harperinsure.com/ "Harper Homepage") (Evidence: Not publicly disclosed; scope: Checked the transportation industry page and homepage insurer-logo panel on 2026-09-23; no carrier names found for commercial auto specifically..) | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. [6](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 | Harper says its transportation practice, which includes commercial auto liability, covers freight carriers, trucking companies, passenger transport services and specialized transportation operators. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") (Evidence: Company-reported; scope: Transportation industry page 'Who this is for' section; general small-business intake elsewhere on the site does not repeat this list..) | The reviewed product page does not state separate eligibility rules for Business Auto; the general quote and advisor route is not proof that a particular business qualifies for it. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [5](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms..) |
| Coverage Features | Harper describes commercial auto liability as coverage for vehicle accidents and third-party injuries during transportation operations, alongside a separate physical-damage coverage for collision and comprehensive damage to the vehicles themselves. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [4](https://www.harperinsure.com/ "Harper Homepage") (Evidence: Company-reported; scope: Transportation industry page coverage callouts; the homepage separately describes commercial auto with 'coverage limits your contracts accept' rather than published limit amounts..) | THREE's Business Owners Policy page lists Business Auto among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Official THREE package marketing for Business Auto. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy..) |
| Limits and Retentions | Harper's reviewed pages do not publish commercial auto liability or physical-damage limits and deductibles; the homepage says only that coverage comes with 'limits your contracts accept,' meaning the buyer's own contracts, not a published Harper figure, set the target. [4](https://www.harperinsure.com/ "Harper Homepage") [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") (Evidence: Not publicly disclosed; scope: Checked the homepage and transportation industry page on 2026-09-23..) | The reviewed public product page does not state a separate limit or deductible for Business Auto; THREE says the quote-specific insurance summary lists limits and deductibles. [7](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [6](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible..) |
| Risk Services | Harper says it delivers proof-of-insurance documents quickly to support FMCSA operating-authority requirements, and describes explaining commercial auto, cargo coverage and FMCSA requirements in plain terms. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") (Evidence: Company-reported; scope: Transportation industry page 'Why Harper' section..) | Confirm in your quote. |
| How to Apply | You can request a commercial auto quote through Harper's online intake by selecting the 'Work vehicles (commercial auto)' checkbox, or by using the transportation-specific intake form, along with the business's state and estimated annual revenue. [4](https://www.harperinsure.com/ "Harper Homepage") [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") (Evidence: Company-reported; scope: Homepage and transportation industry page quote-intake forms..) | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. [5](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..) |
