It's the first question every owner-operator and fleet manager asks, and the honest answer is: it depends. But "it depends" isn't useful when you're trying to budget. So here are real ranges, the factors that move them, and what actually drives the number up or down.
The short answer
For an owner-operator running under their own authority, full commercial truck insurance commonly runs about $9,000 to $17,000 per truck per year, or roughly $900 to $1,800 a month once you add up the full stack of coverages. Drivers leased onto a motor carrier pay far less, often $250 to $500 a month, because the motor carrier's policy covers much of the exposure.
Those are industry ranges, not a quote. Where you land inside them, or outside them, comes down to a handful of factors.
What moves your premium
- Driving record and CSA scores — a clean MVR is the single biggest lever on price.
- Years in business — new authorities pay more; a 2+ year track record earns better rates.
- What you haul — general freight prices differently than hazmat, reefer, or high-value cargo.
- Where you run — radius of operation and the states you drive in change the risk.
- Equipment value and age — physical damage premium tracks the value of the truck and trailer.
- Coverage limits and deductibles — higher limits cost more; higher deductibles cost less up front.
The full stack of coverages
When people compare "truck insurance" quotes, they're often comparing different things. A complete commercial trucking program usually includes several distinct coverages, each with its own premium:
- Primary liability — required for authority; covers injury and property damage you cause.
- Physical damage — comprehensive and collision on your own equipment.
- Motor truck cargo — the freight you haul, often worth more than the truck.
- Non-trucking (bobtail) liability — when the truck is used off-dispatch.
- Plus optional layers: trailer interchange, reefer breakdown, and more depending on your operation.
Why the cheapest quote is rarely the cheapest policy
The fast-quote model gets you a number quickly by shopping the same handful of secondary-market carriers every broker can reach. That's fine until you have a claim and discover the coverage was thin, the carrier is slow, or the policy gets non-renewed after one incident.
Premium A-rated carriers, the ones that price a clean fleet fairly and handle claims well, take longer to place because they underwrite carefully. The extra time is the point. A policy that's $50 a month cheaper but leaves a cargo gap can cost you a truck's worth of freight on a single load.
How to actually lower your cost
The durable ways to reduce premium aren't tricks, they're operational: keep your MVRs and CSA scores clean, build time in business, choose deductibles you can actually absorb, and work with a broker who can present your operation to markets that reward good risk.
That last point is where a specialist earns its keep. We place your submission with the carriers that match your operation, not just the ones that answer first.
