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 Chubb underwrites commercial auto on ISO forms with a Broad Form endorsement for industries from manufacturing to oil and gas. Harper takes one transportation application and calls markets that write commercial auto for freight, trucking, passenger transport and specialized operators, including FMCSA proof-of-insurance documents.

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

Commercial auto insurance addresses liability and vehicle-damage exposures from vehicles used in business. [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") ## Key Differences in Commercial Auto Insurance ### Chubb Industries vs. Transportation Operators Chubb underwrites commercial auto for industries including manufacturing, climate tech, natural resources, financial and professional services, technology, life sciences, media, federal contractors, oil and gas, and wholesalers. Harper’s transportation practice covers freight carriers, trucking companies, passenger transport services and specialized transportation operators, calling the insurance companies that write commercial auto for that kind of operation rather than underwriting the policy itself. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") [8](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [9](https://www.harperinsure.com/ "Harper Homepage") ### Broad Form vs. Liability Plus Physical Damage Chubb uses ISO’s revised multi-state forms and a Commercial Auto Broad Form Endorsement (broad form insured, fellow employee coverage where allowed, rented-auto coverage for employees, auto loan/lease gap) plus a High Value Vehicle endorsement. 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. Harper’s reviewed pages do not name the issuing insurer. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") [8](https://www.harperinsure.com/industries/transportation "Transportation Insurance") ### How You Buy, Filings and Limits You can request a Chubb quote online or through an appointed agent; bundled Total Account Solution auto includes PIP and UM/UIM up to $1 million. Harper delivers proof-of-insurance documents quickly to support FMCSA operating-authority requirements, takes intake by selecting “Work vehicles (commercial auto)” or a transportation form with state and estimated annual revenue, and says coverage comes with limits your contracts accept rather than a published Harper figure. [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") [8](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [9](https://www.harperinsure.com/ "Harper Homepage") ## What to Confirm in Commercial Auto Insurance Quotes - Ask Harper which market it would call and whether FMCSA filings are included. [8](https://www.harperinsure.com/industries/transportation "Transportation Insurance") - Ask Chubb whether MCS-90 or motor-carrier filings are available on its ISO form if you need operating authority. [4](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance") - Compare Chubb’s bundled PIP and UM/UIM up to $1 million with the contract limits Harper aims to meet. [5](https://www.chubb.com/us-en/business-insurance/workers-compensation-small.html "Workers' Compensation Insurance for Small Business") [9](https://www.harperinsure.com/ "Harper Homepage") - Confirm whether Harper quotes physical damage on a separate coverage, and whether Chubb’s Broad Form loan/lease gap applies.
