Your commercial vehicles aren't covered by personal auto insurance—and neither are your pockets if you get sued. Commercial auto insurance is non-negotiable for any business operating vehicles, but figuring out the right coverage limits can feel like guesswork. Here's how to calculate what you actually need.
State Minimums Are a Starting Point, Not a Finish Line
Every state mandates minimum liability coverage for commercial vehicles, but these floors are dangerously low. Most states require $25,000 bodily injury per person and $50,000 per accident, with property damage starting at $20,000. If your commercial vehicle causes a serious accident—especially one involving multiple vehicles or injuries—these limits evaporate instantly.
A single at-fault collision injuring two people can easily exceed $100,000 in medical costs alone. Judgments routinely climb to $250,000–$500,000 or more depending on injury severity and your state. Meeting only your state's minimum is betting your business on luck.
Calculate Coverage Based on Your Vehicle and Cargo Value
Your vehicle's replacement cost matters. A delivery van worth $30,000 and a tractor-trailer worth $150,000 need different protection. Start here:
- Vehicle value: Insure for at least the replacement cost. If you financed the vehicle, your lender will require collision and comprehensive coverage up to that amount.
- Cargo value: If you carry products or materials, insure the typical cargo value you transport. A plumbing supply truck might carry $5,000–$15,000 in materials; a food delivery vehicle might carry $500–$2,000.
- Business interruption risk: If one vehicle going down halts your operations, you need higher limits and possibly commercial auto coverage that includes rental reimbursement.
For most small businesses, liability limits of at least $100,000 per person and $300,000 per accident are prudent. Larger operations or those carrying valuable cargo should push to $250,000–$500,000.
Fleet Size Changes Your Approach
A single commercial vehicle has different risk than a fleet of 10. Insurers calculate fleet premiums differently—usually offering better per-vehicle rates but requiring you to cover more aggregate exposure.
For a 5-vehicle fleet, assume you'll pay $1,200–$2,500 per vehicle annually for basic liability and collision coverage. For 20+ vehicles, rates often drop to $800–$1,500 per vehicle, but your total premium scales with fleet size. A fleet of 15 vehicles might run $12,000–$25,000 yearly depending on vehicle type, driver history, and coverage limits.
Fleet operators should also consider:
- Uninsured motorist coverage: Protects you if an uninsured driver causes damage. Standard in most policies; verify your limits.
- Hired and non-owned auto coverage: Covers vehicles you don't own but use for business (rentals, borrowed equipment trailers). Costs $300–$800 annually for most small fleets.
- Physical damage coverage: Collision and comprehensive. Collision covers accidents; comprehensive covers theft, weather, and vandalism. Skip this only if your vehicles are fully paid off and replaceable.
Industry and Usage Matter More Than You Think
A plumbing contractor whose van sits parked 60% of the time has different risk than a delivery service running routes 12 hours daily. Insurers assess annual mileage, territory (local vs. multi-state), cargo type, and driver experience.
High-risk factors that raise premiums include:
- Hazardous materials transport
- Long-haul interstate driving
- Younger or less experienced drivers
- Multiple prior claims or violations
Safer operations—local deliveries, established drivers, excellent safety records—qualify for discounts of 10–25%.

Don't guess. Contact at least three insurers with identical vehicle and coverage details. Prices vary wildly; a $150,000 liability limit might cost $1,100 at one carrier and $1,800 at another.
Specify your exact needs: vehicle type, usage, annual mileage, driver count, desired deductible ($500, $1,000, or higher), and any add-ons. You can compare trusted commercial auto insurance providers side-by-side through Mercoly, which helps you find and evaluate options in one place rather than calling dozens of brokers individually.
Frequently Asked Questions
Q: Will my personal auto insurance cover my commercial vehicle? No. Personal policies explicitly exclude business use. Operating a commercial vehicle on a personal policy voids your coverage and may result in denial of claims.
Q: Is hired and non-owned auto coverage necessary for a small business? If your employees or contractors ever use their personal vehicles for business tasks, or if you occasionally rent vehicles, this coverage is critical—it fills gaps that neither your policy nor theirs may cover.
Q: How often should I review my commercial auto insurance limits? At minimum annually, or whenever your fleet size, vehicle values, or business scope changes. Growing businesses often underestimate their exposure and need higher limits.
