Commercial Auto vs. Personal Auto
for California Contractors (2026)
Using personal auto insurance for your work truck is one of the most common and costly mistakes CA contractors make. Here's exactly why — and what commercial auto covers instead.
⚠️ Personal auto policies void coverage for business use
If you are in an accident while driving to a job site, hauling materials, or transporting tools, your personal auto insurer will deny the claim. This leaves you personally liable for all damages.

No. Personal auto insurance policies contain a 'business use exclusion' that voids coverage if the vehicle is used for business purposes. If you are in an accident while driving to a job site, hauling materials, or transporting tools, your personal auto insurer will deny the claim. California contractors need commercial auto insurance for any vehicle used for work.
What does commercial auto cover that personal auto does not?
Commercial auto covers business use of vehicles, higher liability limits required for contractors, tools and equipment in transit (with endorsement), hired and non-owned auto liability, and multiple drivers on the same policy. Personal auto excludes all business use and has lower liability limits.
