Commercial vehicles are the backbone of many contracting businesses in California. Whether you're a general contractor, plumber, electrician, or landscaper, your work van or truck isn’t just transportation—it’s a mobile asset, carrying expensive tools, equipment, and the responsibility of your business operations.
However, many contractors make costly errors when securing commercial auto insurance in California—mistakes that can lead to denied claims, regulatory fines, or serious financial setbacks.
At 1099 Insurance Broker, we’ve spent over 30 years helping California contractors protect their businesses. In this article, we’ll break down the top five mistakes contractors make when purchasing commercial auto coverage—and how to avoid them.
1. Assuming Personal Auto Insurance Will Cover Business Use
One of the most common and risky mistakes is relying on a personal auto policy to cover a work vehicle.
Why It’s a Problem:
Personal auto insurance is intended for vehicles used for individual or non-commercial purposes. If you get into an accident while transporting tools, driving between job sites, or hauling materials, your insurer may deny the claim because the use was commercial.
The Solution:
If your vehicle is used in any capacity for business, you need California commercial auto insurance. Commercial policies provide liability, collision, and comprehensive protection specific to business risks.
According to theCalifornia Department of Insurance, using personal insurance for business use violates most policy terms and could result in denied claims or policy cancellation.
2. Choosing State Minimum Liability Limits
California mandates minimum liability insurance for all registered vehicles, but for contractors, the bare minimum is rarely sufficient.
Why It’s a Problem:
Contractors often drive larger vehicles with heavier loads. If you're found at fault in an accident, damages could easily exceed the minimum required coverage, leaving your business liable for the difference.
The Solution:
Consider liability limits that match the scope of your work. Many contractors in California choose at least $1 million in liability coverage, especially when required by general contractors or municipalities.
3. Failing to List All Drivers or Business Uses
Omitting drivers or business activities during policy setup is a common mistake that can lead to significant coverage issues.
Why It’s a Problem:
If an employee drives your commercial vehicle and they’re not listed on your policy, your insurance company might deny your claim. Similarly, if you don’t disclose that you transport hazardous materials, for example, you may not be covered for related incidents.
The Solution:
Be honest and transparent about how your vehicles are used and who is behind the wheel. If your operations change over time, update your policy with your insurance agent.
4. Overlooking Tools and Equipment Coverage
Many contractors assume that everything in their work van is covered under their commercial auto policy. Unfortunately, that’s not the case.
Why It’s a Problem:
Commercial auto insurance protects the vehicle itself—but not the contents inside. If your van is broken into and tools are stolen, you may have no coverage unless you have added endorsements or separate equipment insurance.
The Solution:
Talk to your insurance provider about adding inland marine coverage or tools and equipment insurance to your policy. These endorsements are affordable and protect your livelihood from theft or damage.
5. Not Working with a Specialized Independent Agency
Choosing the wrong insurance provider can leave gaps in your coverage or cost you more than necessary.
Why It’s a Problem:
Many direct-to-consumer insurers don’t understand the specific needs of contractors in California. You might end up with generic coverage that doesn’t reflect your industry, or you might miss out on savings through bundling or carrier discounts.
The Solution:
Work with an experienced independent agency like 1099 Insurance Broker. We represent multiple A-rated carriers and tailor each policy to the contractor’s trade, location, and vehicle type. We also stay up to date on California regulations, so your coverage remains compliant and effective.
Additional Mistakes to Avoid
- Failing to regularly review your policy. Business changes—so should your coverage.
- Not requesting a certificate of insurance (COI). Many contractors lose out on jobs due to missing documentation.
- Ignoring non-owned vehicle risks. If employees drive their own vehicles for business, make sure you're protected.
FAQs
Do I need commercial auto insurance if I’m self-employed?
Yes. If you use your vehicle for work purposes—such as transporting tools or traveling to job sites—you need commercial auto insurance in California.

Final Thoughts: Trust the License — It Still Matters
The $1,000 exemption makes small repairs more accessible. That’s a win for many Californians. But it doesn’t replace the trust, protection, and professionalism that comes with hiring a licensed contractor.
Whether you’re a homeowner looking for peace of mind or a tradesperson building a business, the license isn’t just a formality — it’s a foundation.
