Embarcadero Risk brings together source-based comparisons for businesses moving people and goods.Research updated 2026-09-30

Chubb underwrites commercial auto as a standalone policy or BOP add-on and offers broad-form endorsements and fleet-safety resources. THREE lists Business Auto in its combined BOP, while its reviewed record leaves vehicle terms to the quote.

What Are the Key Differences Between Chubb and THREE by Berkshire Hathaway 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. [5] [1]

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. [5] [6] [2]

  • Ask THREE for vehicle schedules, liability limits, and any available fleet-risk services. [1]
  • Compare endorsements for rented vehicles, loan gaps, and hired/non-owned autos. [5] [1]

THREE by Berkshire Hathaway

  • role: 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.

  • coverage: 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. 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.company-reportedSource ↗Source ↗
  • insurer: The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. 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.company-reportedSource ↗
  • application: THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. 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.company-reportedSource ↗
  • limits: 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. No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible.not-disclosedSource ↗Source ↗
