How Much Does Commercial Truck Insurance Cost? What California Truckers Should Know
Key Takeaways
- Industry benchmark: U.S. motor carriers paid an average of 10.6 cents per mile for liability and cargo insurance in 2025, up 3.9% from 2024, according to the American Transportation Research Institute (ATRI).
- Your price will be different. Driving record, years in business, cargo, routes, and coverage limits can move your premium far above or below the average.
- California adds its own factors, including state permit filings and one of the highest cargo theft rates in the country.
- The cheapest policy isn’t always the cheapest choice. Low limits can cost you loads if brokers and shippers require more coverage.
- You can lower your premium with a clean record, the right deductibles, and accurate information on your application.
“How much is truck insurance?” is the first question most owner-operators ask, and the hardest one to answer with a single number. Two trucks parked side by side can have very different premiums.
This guide gives you a reliable industry benchmark, explains what drives your price, and shows you how to keep costs under control without leaving gaps in your coverage.
The Industry Benchmark: Cost per Mile
The most reliable public benchmark comes from the American Transportation Research Institute (ATRI), which surveys motor carriers every year on what it costs to run a truck.
In its 2026 report, covering 2025 data, ATRI found:
- Truck insurance premiums averaged 10.6 cents per mile in 2025, up from 10.2 cents in 2024.
- That’s a 3.9% increase in one year.
- Early 2026 data showed insurance costs still rising, up another 6.4% in the first quarter.
To put it in perspective: at that average, a truck that runs 100,000 miles a year would pay about $10,600 in insurance. This is only an illustration based on a national average. It is not a quote, and your premium can be much higher or lower.
What Drives Your Premium
Insurers price every truck based on risk. These are the factors that matter most.
Your Driving Record and CDL Experience
This is usually the biggest factor. Accidents, moving violations, and inspection problems raise your rate. More years of clean CDL driving lower it.
Years in Business
New authorities typically pay more because they don’t have a track record yet. Rates often improve as you build a few years of safe, claim-free history.
Your DOT Safety Record
Insurers review your inspection and safety history. A clean record can help you get better pricing. Learn more in our guide on how a clean DOT record can lower your truck insurance quotes.
What You Haul
General dry freight is usually the baseline. Refrigerated loads, high-value goods, and hazardous materials carry more risk and higher premiums.
Where You Drive
Local routes within Southern California are priced differently than long-haul interstate runs. Your operating radius and the areas you travel affect your risk.
Your Truck
The age, value, and type of your tractor and trailer affect physical damage premiums. A newer, more expensive truck costs more to repair or replace.
Your Coverage and Limits
Higher liability and cargo limits cost more, and so does adding physical damage coverage. The limits you need depend on your operation, the law, and your contracts.
Your Claims History
Past claims tell insurers how likely you are to file again. A history of frequent or large claims raises premiums.
Your Deductibles
A higher deductible lowers your premium, but you pay more out of pocket if you have a claim.
California Factors to Keep in Mind
State permit filings. Most carriers that haul property within California need a Motor Carrier Permit (MCP) from the DMV, and your insurer must file proof of liability coverage with the state. If you cross state lines, the FMCSA also requires your insurance on file, with a minimum of $750,000 in liability for most general freight.
Cargo theft. California leads the nation in cargo theft. In the first quarter of 2026, the state accounted for 36% of reported cargo theft incidents in the U.S., according to Overhaul’s quarterly report. That risk can affect the cost and terms of cargo coverage.
Leased-On vs. Your Own Authority
How you operate changes what you pay for:
| Leased to a Motor Carrier | Your Own Authority | |
|---|---|---|
| Primary liability | Usually covered by the carrier while you’re dispatched | You buy it yourself |
| Federal and state filings | Handled under the carrier’s authority | Your insurer files them for you |
| What you usually buy | Non-trucking liability or bobtail, plus physical damage | Primary liability, cargo, physical damage, and more |
| Typical cost | Lower, because the carrier carries the main liability | Higher, because you carry the full risk |

Why the Cheapest Policy Can Cost You Loads
Meeting the legal minimum keeps you on the road, but it may not get you hired. Industry contracts regularly require $1,000,000 in auto liability, and major shippers may ask for more, plus cargo and general liability coverage.
If your limits are too low, you may lose access to better-paying brokers and shippers. When you compare quotes, compare the coverage too, not just the price.
How to Lower Your Premium Without Losing Coverage
- Protect your driving record. Every year of clean driving helps.
- Keep your truck and paperwork inspection-ready to avoid violations.
- Choose deductibles you can afford if you need to file a claim.
- Describe your operation accurately. Your real radius, cargo, and drivers help insurers price you correctly.
- Avoid gaps in coverage. A lapse can make your next policy more expensive.
- Review your policy at every renewal. Your profile and the market change every year.
- Work with an independent agency that can compare several insurers for your exact operation.
What You Need for an Accurate Quote
