Commercial Auto Insurance
for California Contractors —
Trucks, Vans, Fleets & Trailers
Personal auto insurance won't cover your work truck. The moment you're driving to a job site, hauling tools, or towing a trailer for your business, you need commercial auto insurance — or one accident could cost you everything.
Why Contractors Need Commercial Auto Insurance
California contractors rely on their vehicles every day — driving to job sites, hauling materials, towing equipment trailers, and transporting crews. But personal auto insurance policies contain a business use exclusion that can void your entire claim the moment your vehicle is used commercially. This isn't a technicality buried in fine print — it's a standard policy provision that California insurers enforce aggressively.
Commercial auto insurance is specifically underwritten for business vehicle use. It provides the liability limits that California general contractors, property managers, and project owners require — typically $1,000,000 combined single limit (CSL) per occurrence — and covers the full range of vehicles in a contractor's fleet, from a single pickup truck to a 20-vehicle operation with dump trucks, flatbeds, and equipment trailers.
Beyond liability, commercial auto insurance protects your investment in your vehicles with collision and comprehensive coverage, fills the gap left by your fleet policy with Hired & Non-Owned Auto (HNOA) coverage for employees using personal vehicles, and ensures compliance with California DMV Motor Carrier Permit requirements and federal DOT regulations for vehicles over 10,001 lbs GVWR.
What Personal Auto Does NOT Cover
Your personal auto insurer can deny the entire claim if the vehicle was being used commercially at the time of the accident. This includes:
What Commercial Auto Insurance Covers
Liability Coverage
Pays for bodily injury and property damage you cause to others while driving for business. Required by California law and virtually every GC contract. Minimum $1M CSL recommended.
Collision Coverage
Pays to repair or replace your vehicle after an at-fault accident, regardless of who caused it. Essential for financed or leased vehicles and high-value work trucks.
Comprehensive Coverage
Covers non-collision losses: theft, vandalism, fire, flood, hail, and falling objects. Contractor vehicles parked at job sites overnight are high-theft targets.
Hired & Non-Owned Auto (HNOA)
Covers your business liability when employees use their personal vehicles for work errands. Fills the gap your fleet policy doesn't cover. Often required by GC contracts.
Uninsured Motorist
Protects you when an at-fault driver has no insurance or insufficient coverage. California has one of the highest rates of uninsured drivers in the nation (~17%).
Medical Payments (MedPay)
Pays medical expenses for you and your passengers after an accident, regardless of fault. Supplements your health insurance and covers deductibles and co-pays.

DOT Numbers & California Motor Carrier Permits
California contractors operating commercial vehicles over 10,001 lbs GVWR are subject to federal DOT and state MCP requirements. Failure to comply can result in fines, out-of-service orders, and voided insurance claims.
We work with contractors to ensure their commercial auto policies meet the minimum liability requirements for DOT-regulated operations and can provide the insurance filings (MCS-90, Form E) required by the FMCSA and California DMV.
Fleet Insurance for Contractor Companies
If your contracting business operates three or more vehicles, a fleet policy is almost always more cost-effective than insuring each vehicle individually. Fleet policies consolidate all your vehicles under a single policy with one renewal date, one premium payment, and a single point of contact for all claims and certificates of insurance.
Fleet pricing typically delivers 10–20% savings compared to individual vehicle policies. For larger fleets (10+ vehicles), we can structure the policy with a fleet deductible program that further reduces premiums by self-insuring small claims while maintaining full coverage for catastrophic losses.
Which Contractor Trades Need Commercial Auto?
Every trade that uses vehicles for business needs commercial auto insurance. Here's how coverage needs vary by trade:
Important: Commercial Auto Does NOT Cover Your Tools
Commercial auto insurance covers the vehicle — not the tools, equipment, and materials inside it. Contractor tool theft from vehicles is one of the most common claims in California. A single break-in can result in $10,000–$50,000 in losses that your commercial auto policy won't cover.
A Tools & Equipment Floater (Inland Marine) covers your tools and equipment wherever they are — in your truck, on a job site, or in storage. We can bundle it with your commercial auto policy for comprehensive protection.
