## 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

### Vehicle Coverage and Tailoring

CNA specifies liability for owned, hired and non-owned business vehicles and lists automobile physical damage with optional Drive Other Car coverage for executives. Liberty Mutual names liability, bodily injury, physical damage and uninsured-motorist coverages, and says underwriters tailor solutions to industry, fleet, location and vehicle use. For a business with mixed vehicle types or changing operations, compare how each proposal schedules vehicles and drivers rather than relying on these overview lists. [4](https://www.cna.com/products/commercial-auto "Commercial Auto Insurance for Businesses | CNA Insurance") [4](https://www.cna.com/products/commercial-auto "Commercial Auto Insurance for Businesses | CNA Insurance") [7](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet") [7](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet")

### Risk Support and Access

CNA names Driver Distractions and Cargo Securement programs and claims support. Liberty Mutual's cited product page lists coverages but does not establish an online application or binding route. Ask Liberty Mutual how its team handles quoting and ask CNA which safety resources are available to the fleet. [4](https://www.cna.com/products/commercial-auto "Commercial Auto Insurance for Businesses | CNA Insurance") [7](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet")

## What to Confirm in Commercial Auto Insurance Quotes

- Request Liberty Mutual's vehicle-specific limits, deductibles and quote route. [7](https://business.libertymutual.com/commercial-solutions/commercial-auto-and-fleet/ "Commercial Auto and Fleet")
- Ask CNA for the Drive Other Car endorsement and service details in writing. [4](https://www.cna.com/products/commercial-auto "Commercial Auto Insurance for Businesses | CNA Insurance") [4](https://www.cna.com/products/commercial-auto "Commercial Auto Insurance for Businesses | CNA Insurance")
