## What Are the Key Differences Between Chubb and Harper Commercial Auto Insurance?

### Transportation Operators vs. Named Business Industries

Harper serves freight carriers, trucking companies, passenger transport and specialized transportation operators. Chubb lists manufacturing, technology, life sciences, oil and gas and wholesalers among eligible industries. Choose Harper if you run a regulated transportation operation needing FMCSA proof; choose Chubb if your business falls within its named industry classes. [3](https://www.harperinsure.com/industries/transportation "Transportation Insurance") [1](https://www.chubb.com/us-en/business-insurance/chubb-commercial-auto.html "Commercial Auto Insurance")

### 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.

### 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.
