What Drives the Price of Commercial Truck Insurance

Usually the largest recurring cost after the truck payment and fuel, and the one most likely to be quoted at double what a new authority expected.

We are not going to print a premium figure. Quotes vary by an enormous margin on factors specific to you, and any number published on a website is either out of date or was invented for the article. What we can do is explain exactly what moves the number, so the quotes you receive make sense.

The legal floor

Under 49 CFR § 387.9, the minimum public liability limits for for-hire carriers of property are:

Operation	Minimum
Non-hazardous property, GVWR under 10,001 lbs (for-hire, 49 CFR § 387.303)	$300,000
Non-hazardous property, GVWR 10,001 lbs or more	$750,000
Oil and certain listed hazardous materials	$1,000,000
Bulk hazardous substances in cargo tanks and certain high-hazard materials	$5,000,000

The $750,000 line applies to for-hire carriers of general freight in interstate commerce. The hazardous materials lines also apply to private carriers. Household goods carriers have an extra federal cargo requirement of $5,000 per vehicle and $10,000 per occurrence, which is the one case where cargo cover is a filed federal minimum rather than a broker demand.

The floor nobody actually operates at

Brokers commonly require $1,000,000 in auto liability and $100,000 in cargo before tendering a load. Meeting only the federal minimum leaves you legal and largely unable to find work, which is why the $750,000 figure is close to theoretical for a general freight carrier.

The coverages, and which are genuinely optional

Coverage	What it does	Optional?
Auto liability	Injury and damage you cause to others	No — federally required and filed
Cargo	The freight you are carrying	In theory; in practice brokers require it
Physical damage	Your own truck and trailer	Only if you own it outright
Non-trucking liability	Use of the truck off dispatch	Usually required if leased on
Trailer interchange	Trailers you pull that are not yours	Depends on your operation
Occupational accident or workers' compensation	Injury to you or your drivers	Depends on state and structure

What underwriters actually price on

Time in business under your own authority. The single biggest factor. A brand-new authority has no loss history, and the absence of a record is priced as risk, not as a clean slate.
Your driving record. Violations and accidents on the MVR, over the last three to five years.
CDL experience. Years driving, and years in the class of equipment you will run.
Radius of operation. Local, regional or long haul.
Commodities. General freight prices differently from refrigerated, cars, hazmat or high-value electronics.
Equipment value and age. Drives physical damage cover.
Where you are based. Garaging address matters more than people expect.
Loss runs. If you have prior coverage, your claims history follows you.

Practical ways the number comes down

Survive the first year. Most of the new-authority loading disappears once you have a clean year of history.
Get multiple quotes, and start early. Insurance is usually the long pole in getting authority, not the paperwork.
Ask what changes the price. Deductible, radius, driver criteria — a good agent will show you the levers rather than a single number.
Do not under-insure to save the premium. One at-fault accident above your limit ends the business and follows you personally.

Whatever you are quoted, put the annual figure into the cost per mile calculator before you commit. Insurance is a fixed cost, so it lands hardest on operations with low annual mileage.

How the federal requirement actually works

Three mechanics catch new carriers out, and none of them are about price.

Your insurer files the proof, not you. FMCSA requires the insurance company to file the certificate (Form BMC-91 or BMC-91X for liability) on your behalf once you have a docket number. FMCSA says the filing is due within 20 days of your application being published in the FMCSA Register, and that authority is not granted until it is on file. A name or address that does not exactly match your registration delays it further.
The MCS-90 endorsement protects the public, not you. Every for-hire interstate liability policy carries it. Under its wording, the insurer pays a final judgment for public liability whether or not the truck involved is described in the policy — and you agree to reimburse the insurer for any payment it would not otherwise have owed. It does not cover the cargo you haul. In practice that means an unlisted truck or an excluded driver can turn an accident into a personal debt.
Cancellation runs on notice. Under 49 CFR § 387.7(b)(1), the insurer or the carrier may cancel by giving 35 days' notice in writing. A notice of cancellation for non-payment is a deadline, not a formality. Proof of the cover must be kept at your principal place of business.

Why the same premium costs more on fewer miles

Insurance is billed per year, or per unit per year, not per mile. Whatever you are quoted, the cost per mile depends on how many miles you spread it across. The table below uses $10,000 of annual premium as a unit for the arithmetic — it is not a quote and not a market price. Scale it to your own figure.

Illustrative arithmetic: $10,000 ÷ annual miles. The middle row uses ATRI's 2025 average of 85,991 miles per truck.
Annual miles	Cost per mile, per $10,000 of premium	Relative to 110,000 miles
60,000	$0.167	1.83×
85,991	$0.116	1.28×
110,000	$0.091	1.00×

The same policy costs 83 percent more per mile at 60,000 miles than at 110,000. That is why a regional or part-year operation feels insurance far more than a long-haul truck does, even on an identical quote.

For orientation only: ATRI's 2026 report put the insurance line (liability and cargo premiums) at 10.6 cents per mile across surveyed fleets in 2025, up 3.9 percent, with premiums in the first quarter of 2026 running 6.4 percent above the 2025 average. Those are averages for established fleets with loss history and fleet pricing. They are useful for seeing the direction of travel, and useless as a forecast of what a new one-truck authority will be quoted.

Comparing quotes, step by step

Send every agent the same specification. Same liability limit, same cargo limit, same deductibles, same radius, same commodities, the same listed drivers and the same units. Quotes built on different assumptions cannot be compared.
Ask for the premium broken down by coverage. Liability, cargo, physical damage, non-trucking liability and trailer interchange priced separately show you where the money is.
Read the cargo exclusions against what you haul. Commodity exclusions, unattended-vehicle conditions and, for refrigerated freight, whether reefer breakdown is covered at all.
Confirm who files, and when. Ask the agent to confirm the BMC-91 or BMC-91X filing once your docket number is issued.
Ask about the payment terms. Down payment, instalments, and what happens after a missed payment.
Convert the annual total to a per-mile figure at realistic miles, using the arithmetic above, and only then compare it with what loads pay.

Common mistakes

Adding a truck or driver without telling the insurer. The MCS-90 may still pay the injured party; the reimbursement clause means you may then owe the insurer.
Giving an address that is not where the truck is actually garaged. Garaging location is priced; misstating it is a misrepresentation that can undermine a claim.
Buying cargo cover on headline limit alone. A $100,000 limit with an exclusion for the commodity you carry is worth nothing on that load.
Assuming a carrier's policy covers you off dispatch. If you are leased on, the motor carrier's liability usually covers you under dispatch; the time in between is what non-trucking liability is for.
Picking a deductible you could not pay this month. A low premium with a deductible larger than your cash reserve moves the risk back onto you.

Edge cases

Vehicles under 10,001 lbs. Cargo vans and some hotshot setups run for-hire under the $300,000 federal minimum, but brokers often apply the same $1,000,000 requirement. See cargo van freight and commercial auto insurance for light vehicles.
Intrastate-only operations. The federal $750,000 entry is for interstate for-hire carriage; states set their own requirements for purely intrastate work.

Frequently asked questions

What is the minimum insurance FMCSA requires?

$750,000 in public liability for non-hazardous property in vehicles rated 10,001 pounds or more, under 49 CFR § 387.9. Higher limits apply to hazardous materials.

Why is my quote so high as a new authority?

Underwriters have no loss history to price against, so a new authority is priced conservatively. It typically improves substantially after a clean first year.

Do I need cargo insurance?

It is not part of the federal financial responsibility minimum for general freight, but brokers routinely require $100,000 in cargo cover before giving you a load.

What is the MCS-90 endorsement?

A federally prescribed endorsement on for-hire interstate liability policies. The insurer pays a final judgment for public liability even if the vehicle is not described in the policy, and you agree to reimburse the insurer for any payment it would not otherwise have owed. It does not cover cargo.

Is the minimum lower for a cargo van?

Yes. For-hire carriers of non-hazardous property in vehicles under 10,001 pounds GVWR need $300,000 in public liability. Brokers frequently ask for more.

Who files my insurance with FMCSA?

Your insurance company files the certificate, usually Form BMC-91 or BMC-91X, on your behalf after you receive a docket number. Your authority is not granted until it is on file.
