2026 QUICK ANSWER
Motor truck cargo insurance covers your legal liability when freight is lost or damaged while in your custody. Most owner-operators carry a $100,000 limit with a $1,000–$2,500 deductible, paying $1,500–$4,000 per year on general freight. Reefer and high-value commodity operators pay more. What the policy doesn't cover is where most claims go wrong. Know your exclusions before you haul.
Motor truck cargo insurance pays for the freight you're legally liable for when it's lost or damaged while in your custody. What you actually pay (and how well the policy performs at claim time) depends on five things: your commodity, your limit, your deductible, your loss history, and how carefully you read what the policy excludes.
What is cargo insurance, and why does it cover you differently than a shipper thinks?
Motor truck cargo insurance, often called motor truck cargo (MTC), is a legal liability policy. That distinction matters more than most drivers realize. It means the policy covers the shipper's freight to the extent you're legally liable for the loss as a carrier, not simply because the freight was damaged while on your truck.
Your liability as a carrier is established under federal law, specifically the Carmack Amendment (49 U.S.C. § 14706), which governs interstate freight claims. Under Carmack, you're presumed liable when cargo is delivered in worse condition than it was tendered to you. The burden then shifts to you to prove an exception: an act of God, shipper fault, inherent vice (a defect in the cargo itself), public enemy, or an act of public authority. If you can't establish one of those defenses, you owe the shipper the actual loss in market value.
Cargo insurance steps in to pay that liability. The policy pays for direct physical loss to covered property (the freight itself) while it's in your exclusive physical custody and control, in transit on your truck, or during the loading and unloading process. Once the consignee signs for the load at the destination, coverage ends.
One practical note: cargo insurance isn't the same as shipper's interest insurance, which covers the shipper's goods regardless of carrier fault. You're buying protection for your liability exposure, not a blanket property policy for the freight.
Is motor truck cargo insurance required?
Motor truck cargo insurance isn't federally required for most property carriers. The FMCSA mandates a $750,000 floor for primary liability under 49 CFR Part 387, but sets no cargo coverage minimum for dry van, flatbed, or reefer operations. If you're running general freight, you won't lose your operating authority for not carrying it.
In practice, it's still required. Every freight broker's carrier packet requires a certificate of insurance showing cargo coverage before they'll dispatch a single load. The standard floor in most carrier packets is $100,000. Haul without cargo coverage and you won't get freight from brokers, which is the primary load source for most owner-operators. You'll also be personally liable for every load you damage or lose, with no insurer to step in on your behalf.
HOUSEHOLD GOODS EXCEPTION
Household goods movers operate under a different rule: FMCSA requires a minimum of $5,000 per vehicle and $10,000 per occurrence in cargo coverage under 49 CFR Part 387. If you haul household goods, the federal cargo floor applies directly to your operation.
What does motor truck cargo insurance actually cover?
The core coverage is direct physical loss to lawful goods and merchandise while you have exclusive custody of them under a bill of lading (BOL), rate confirmation sheet, or other contract of carriage. That last part is load-bearing language: if there's no written shipping document connecting you to that freight, coverage typically won't apply.
Coverage is active from the moment you take physical custody of the load at the shipper's dock through delivery at the consignee, including ordinary stops, fuel stops, weigh stations, and delays reasonably incidental to the route. Most policies define this window with a transit clock: if a load sits at any location for more than 72 hours, coverage can lapse. Weather-related delays outside your control are usually exempt, but the moment that weather emergency ends, the clock resumes.
Covered perils broadly include external, physical causes: fire, lightning, explosion, windstorm, hail, flood, collision or overturn of the truck, theft of the entire load, stranding on a ferry, and collapse of a bridge or loading structure. The common thread is that something external and sudden has to cause the loss. Gradual, inherent, or self-caused damage is a different story.
Reefer operators: A standard cargo policy likely won't pay if your refrigeration unit breaks down and the load spoils. Most carriers exclude mechanical and electrical breakdown, including reefer unit failure, from the base policy. Refrigeration breakdown coverage can be added as an endorsement, but it comes with its own maintenance requirements. Expect to document regular inspections and keep records the insurer can review if you file a claim.
What motor truck cargo insurance does not cover
The exclusions section of a cargo policy is where claims go to die, and where you're most likely to be genuinely surprised. Read this section before you ever haul a load.
Inherent vice. If the cargo has a quality that causes it to damage or destroy itself (fruits that over-ripen, metal that corrodes, products with latent defects), that's not your fault and it's not a covered loss. Inherent vice is the legal term for this, and it's a hard exclusion in virtually every cargo policy.
Temperature and humidity damage without a covered cause. Produce that sweats because of ambient humidity, or a load that freezes in transit because of cold outside temperatures, is excluded under a standard policy unless there's a covered physical cause (like the truck rolling over or catching fire). This is the exclusion that surprises reefer operators most often.
Mechanical breakdown. The reefer unit quits, the cargo spoils: base policy says no. You need the refrigeration breakdown endorsement, and even then the coverage won't apply if you failed to maintain the unit properly. Most refrigeration breakdown endorsements require documented maintenance logs. If you can't produce them, the claim can be denied.
Theft with caveats. Full load theft is generally covered. Pilferage (a box missing from a partial load, items stolen from a package) typically isn't. If your driver or someone you entrusted with the cargo steals from it, that's also excluded. The coverage is for third-party theft of freight you had no hand in losing. CargoNet and the NICB track cargo theft patterns annually: electronics and pharmaceuticals top the list every year.
Mysterious disappearance and inventory shortage. If you deliver a load short and can't document when or how it happened, that's a mysterious disappearance, and it's excluded. Inventory shortages discovered at delivery without a documented cause don't pay.
Fraud and false pretense. You get conned into releasing the load (a double-brokered load scam, a fraudulent pickup authorization) and the freight disappears. That's considered voluntary parting with possession due to fraud, and it's specifically excluded from most policies. FMCSA has documented the growing frequency of broker and carrier identity theft, and discussions on TruckersReport show how often operators assume cargo insurance protects them from this. It doesn't.
Property not moving under a BOL. Freight you're hauling as a favor, or a load with no written shipping document attached to it, may fall outside coverage entirely. Coverage attaches to your legal liability as a carrier, and that liability is documented by the bill of lading. No BOL, no clear coverage.
Excluded commodities. Most cargo policies exclude certain classes of freight outright, regardless of cause of loss. Common excluded commodities: currency, securities, and negotiable instruments; precious metals and jewelry; fine art; tobacco products; prescription pharmaceuticals; marijuana products; explosives and ammunition; and live animals (with narrow exceptions for death caused by a specified peril). If you regularly haul any of these, you may need a specialty policy or endorsement.
Property held too long in one place. Cargo that sits for more than 72 hours at a stop (even a truck stop, even your own terminal) can fall outside the transit window. Check your policy's exact language on this.
Pre-existing damage. If you pick up a load that's already damaged and don't document it, you own that damage in the eyes of the shipper. Pre-existing damage is excluded: the insurer only pays for damage that occurred while you had the load. This is why a clean, documented inspection at pickup matters, especially for auto haulers and flatbed operators.
EXCLUSIONS THAT TRIP OPERATORS MOST OFTEN
In practice, the claims that get denied fall into four buckets: reefer breakdown without the endorsement, partial theft or pilferage, mysterious disappearance with no documentation, and fraud-based release of the load. Know these before you haul, not after.
How motor truck cargo insurance is priced
Cargo insurance pricing comes down to four variables: commodity risk, limit, deductible, and your loss history. For the full line-by-line breakdown of what insurance costs across every coverage you carry as an authority holder, see our owner operator insurance cost breakdown for 2026.
Commodity. This is the biggest driver of cargo premium. A dry van operator hauling general commodities (paper goods, auto parts, packaged consumer products) is underwriting a very different risk than someone hauling electronics, pharmaceuticals, or high-value freight. Insurers price cargo relative to the theft attractiveness and claim frequency of what you're hauling. Electronics attract cargo theft the way a lot lizard attracts gossip. General dry van freight does not. ATRI research consistently documents the financial impact of cargo theft on owner-operators, and the numbers move significantly by commodity.
Limit. The standard cargo limit that satisfies most brokers and shippers is $100,000. If you're hauling high-value freight, automotive, or anything where a full-load loss could exceed that number, you may need $250,000 or higher. Higher limits cost more, and some commodities (electronics, pharmaceuticals) may require specific underwriting before a carrier will offer them at any limit.
Deductible. Cargo deductibles for owner-operators typically run $1,000–$2,500. A higher deductible lowers your premium but raises your out-of-pocket on every claim. If you're running tight margins and couldn't absorb a $2,500 hit on a small claim, that's worth weighing against the premium savings.
Loss history. A clean record brings standard pricing. A cargo claim in your recent history (especially a large one) can make you harder to write and more expensive to insure. Some carriers won't write cargo at all for operators with two or more claims in the prior three years.
Cargo insurance for a single-truck owner-operator running general commodities under standard limits commonly runs $1,500–$4,000 annually. Reefer operators and those hauling higher-value or theft-prone freight can see premiums in the $3,000–$8,000 range or higher, depending on lanes and loss history. Your CSA score through FMCSA's Safety Measurement System is visible to underwriters and factors into your pricing at renewal. Your actual premium depends on all the factors above.
What limit do you actually need?
The $100,000 cargo limit is the industry floor: it's what most freight brokers require in their carrier packets, and it covers most general commodity loads comfortably. But there are situations where $100,000 isn't enough, and taking on a load that exceeds your cargo limit is real exposure.
Consider: a single load of consumer electronics or medical equipment can easily run $200,000–$500,000. If that load is stolen or destroyed, your $100,000 policy pays $100,000 and you're personally on the hook for the rest, subject to your Carmack liability and any limitations in the bill of lading. Many shippers declare a released value (a per-pound limit, often around $0.50/lb for standard freight) in the BOL, which caps their claim. Others declare actual value. Read the BOL before you sign it.
If you haul automotive, electronics, or retail consumer goods in full truckloads, have a candid conversation with your agent about whether $100,000 is the right number, or whether you're chronically underinsured for the freight you're actually running. The American Trucking Associations publishes annual industry data that provides useful benchmarks for what a full-load loss actually costs across freight categories.
How does cargo insurance interact with the bill of lading?
The bill of lading (BOL) isn't just a shipping receipt: it's the contract of carriage, and it's the document that defines the scope of your legal liability on that load. Your cargo policy is written to respond to that liability.
Declared value vs. released value. If the shipper declares a specific value on the BOL, that's the upper bound of what they can claim from you. If the BOL lists a released value (a per-pound rate), that caps the claim even if the actual loss is higher. Most cargo policies pay the lesser of your legal liability, the declared value, the cost to repair or replace the freight, or your policy limit. The BOL determines which of those numbers applies.
Exclusions the shipper agrees to. Some shippers include language on the BOL limiting your liability for certain causes of loss. Those limitations can affect what the shipper can actually recover from you, and therefore what your insurer has to pay.
Who signs and when. Coverage attaches when you take physical custody of the freight under the BOL and ends when the consignee accepts the freight at the destination. Any gap (a load you're holding informally, a transfer of custody to another carrier) needs to be examined against your policy language to confirm coverage is still in place.
Do you need cargo insurance if you're leased on?
If you're leased on to a motor carrier, the carrier may provide cargo coverage under their policy for loads you haul on their authority. But "may provide" is doing a lot of work in that sentence.
You need to know: what commodity restrictions does the carrier's cargo policy have, what is the limit, what is the deductible and who pays it if there's a claim, and whether the carrier's policy covers you in any dispute with a shipper or whether it's structured to protect the carrier only.
If you're leased on, it's easy to assume you're fully covered for cargo. Plenty of operators find out otherwise at claim time. Get the carrier's cargo policy details in writing and have a licensed agent review the lease terms before you assume you have no cargo exposure. You can verify a carrier's active insurance filings through FMCSA's SAFER system. If there are gaps, you may be able to purchase your own cargo coverage even while leased on, though you'll need to understand how the two policies coordinate before you haul a load. OOIDA has documented cases where leased operators discovered cargo exposure only after filing a claim because they never reviewed the carrier's policy terms before loading.
LEASED ON?
The carrier's primary liability covers you while under dispatch. Cargo coverage is a separate question governed by your lease agreement. Before you assume you're covered, get the carrier's cargo policy declarations page, not just the certificate. For the full picture of what leased-on operators need to carry, see our leased-on vs. own authority insurance guide and our non-trucking liability insurance guide. Your leased-on insurance page covers the complete coverage stack.
What happens when you file a cargo claim?
The claims process for cargo is more procedurally intensive than you might expect. Missing a step can result in a reduced payment or an outright denial.
When a loss occurs, your responsibilities generally include:
- Take immediate steps to prevent further damage to the load: secure it, get it into appropriate storage, and don't dispose of anything without the insurer's involvement.
- Notify your insurer promptly. The sooner you report, the smoother the process.
- Document everything at the scene: photos of the cargo, the truck, the damaged items, and the shipping documents.
- Provide the insurer with a sworn proof of loss within the required timeframe, often 60 days from the date of their request.
- Make all shipping records available: BOLs, invoices, rate confirmations, driver logs.
BEFORE YOU FILE
Don't dispose of damaged freight before the insurer has examined or authorized it. Discarding cargo without their approval can void the claim. Salvage rights typically transfer to the insurer once you're paid for a loss. You cannot collect for a loss and then keep or sell the recovered freight.
Payment timelines vary, but most policies commit to paying covered losses within 30 days of receiving a satisfactory proof of loss.
One caveat on quantity and shortage claims: if you're delivering a load short and the shortage isn't explained by documented damage or theft, expect that claim to face scrutiny. Inventory discrepancy without a traceable cause is an excluded peril in most policies. Overdrive and FreightWaves both cover recurring patterns in cargo claim disputes that are worth reading before you're ever in one.
Motor truck cargo insurance companies: what to look for
The market for motor truck cargo insurance includes regional and national commercial truck insurers, specialty markets, and surplus lines carriers for hard-to-place risks. The right company depends on your commodity, your loss history, and your operating profile. For context on how the full insurance market serves owner-operators running under their own authority, see our own authority insurance guide.
Claims handling. Cargo claims can be contentious: competing interests between you, the shipper, and the broker make these messier than most commercial claims. An insurer with a dedicated commercial trucking claims team who understands Carmack liability handles these differently than one routing cargo claims through the same pipeline as a homeowner's. That difference shows at claim time.
Commodity appetite. Some insurers are aggressive writers for general dry van freight and cautious on refrigerated freight, electronics, or specialty commodities. Others specialize in exactly the commodity you haul. Quote with carriers that actually want to write your operation. DAT can give you a sense of which commodity lanes carry the most activity in your region, which affects which markets are most competitive for your operation.
Endorsement availability. If you need refrigeration breakdown, courier coverage, or coverage for specific equipment types, confirm those endorsements are available and understand their terms before binding. Not every cargo insurer offers every endorsement, and the terms vary between carriers.
How limits and deductibles are structured. Confirm what deductible applies per occurrence and whether it interacts with your physical damage deductible on a combined loss. The highest applicable deductible typically applies when both coverages are triggered in the same event. The American Trucking Associations publishes annual benchmarking data that provides useful context for what operators in your segment typically carry.
WHAT TO KNOW BEFORE YOUR FIRST LOAD
Motor truck cargo insurance covers your legal liability for freight in your custody, from pickup under a bill of lading through delivery. The standard limit is $100,000 with a $1,000–$2,500 deductible. General freight premiums typically run $1,500–$4,000 per year. Reefer and high-value commodity operators pay more. What the policy doesn't cover is where most claims go wrong: gradual or inherent damage, reefer breakdown without an endorsement, partial theft and pilferage, loads with no shipping document, cargo held more than 72 hours in transit, and a list of excluded commodities most operators never read until after a denial. Know your exclusions before you haul, not after.

Frequently asked questions
Is motor truck cargo insurance required by the FMCSA?
Not for general freight property carriers. FMCSA mandates minimum primary liability limits but doesn't set a cargo coverage floor for dry van, flatbed, or reefer operations. Household goods movers are the exception: federal rules require $5,000 per vehicle and $10,000 per occurrence. In practice, freight brokers require $100,000 in cargo coverage in their carrier packets. Without it, you won't get dispatched on brokered freight.
What's the difference between cargo insurance and shipper's interest insurance?
Cargo insurance (MTC) covers your liability for freight damage as a carrier. You owe the shipper the value of what was lost or damaged, and cargo insurance pays that obligation. Shipper's interest insurance covers the shipper's goods regardless of whether you're legally at fault. You buy cargo insurance to protect your exposure as a carrier. Shippers buy shipper's interest to protect their own goods.
Does cargo insurance cover a stolen load?
Full load theft is generally covered. Pilferage (individual items or boxes stolen from a partial load) typically isn't. If the theft involves someone in your custody, your driver, or another party you entrusted with the freight, that's also excluded. Document your cargo condition at pickup and delivery on every load.
What happens if I deliver a load short?
If you can't document how the shortage occurred, it's classified as mysterious disappearance and it's excluded. If the shortage resulted from documented damage or theft, it may be covered. Your protection is a detailed inspection at pickup, a signed delivery receipt that notes any shortage, and photos. The operator who documents everything at pickup and delivery is the one whose shortage claims actually pay.
Does my carrier's cargo policy cover me if I'm leased on?
It depends on the carrier's policy terms. Some carriers provide cargo coverage for all freight hauled under their authority. Others have commodity restrictions, sub-limits, or policy structures that leave the operator exposed in a claim. Get the carrier's policy declarations page in writing, not just the certificate of insurance. Verify their active coverage through FMCSA's SAFER system. If there are gaps, a licensed agent can tell you what you'd need to purchase on your own.
How much does motor truck cargo insurance cost per year?
General freight operators typically pay $1,500–$4,000 annually for a $100,000 limit. Reefer operators and those hauling high-value or theft-prone commodities pay $3,000–$8,000 or more. Your specific premium depends on commodity, limit, deductible, loss history, and CSA score. A licensed agent can price it specifically for your operation and commodity.
What is the Carmack Amendment and why does it matter?
The Carmack Amendment (49 U.S.C. § 14706) is the federal law governing carrier liability for freight damage and loss. It establishes that you're presumed liable when cargo is delivered damaged, unless you can prove a specific exception (act of God, shipper fault, inherent vice, public enemy, or act of public authority). Cargo insurance is written to respond to that Carmack liability. Without cargo coverage, you bear that liability personally.
Do I need cargo insurance on every load I haul?
Coverage attaches automatically when you take custody of freight under a bill of lading. There's no load-by-load election: your policy is continuous. If you haul freight with no bill of lading or written shipping document, coverage may not apply to that load. Never take custody of freight without a BOL, and confirm your policy is active and in good standing before your first load of a new policy term.
