Carrier and Shipper Negligence in Freight Shipping: Carmack Claims

Fault in a freight loss claim usually comes down to where the failure happened: carrier and shipper negligence in freight shipping claims is divided by the loading dock, with the shipper responsible for how cargo is packaged, labeled, loaded, and valued before the trailer is sealed, and the carrier responsible for the equipment, the driver, and the handling of the freight once it takes possession. Federal law, specifically the Carmack Amendment at 49 U.S.C. § 14706, then decides how a claim is proved, what the carrier can raise as a defense, and how much you can actually recover.¹

Where the Dividing Line Sits

Once a carrier accepts freight and signs a clean bill of lading, it owes a duty of care equivalent to what a reasonably careful person would exercise under the same circumstances.² Before that moment, the shipper controls everything about the load. Carriers are often barred from the loading area entirely and may never see the inside of a sealed trailer, and that fact does most of the work in sorting out who pays. If the failure traces back to packaging, labeling, or the way the pallets were arranged, the shipper owns it. If it traces to a bad brake, a fatigued driver, or freight that shifted because tiedowns were skipped, the carrier owns it.

What Counts as Carrier Negligence

Equipment That Should Have Been Maintained

Motor carriers must systematically inspect, repair, and maintain every vehicle under their control, and every part affecting safe operation must be kept in proper working condition.³ Drivers complete a written inspection report at the end of each shift covering brakes, tires, steering, and coupling devices, and the next driver must confirm any needed repairs were made before rolling.

Refrigerated trailers generate a steady stream of claims. When a carrier skips scheduled reefer service or lets the unit run out of fuel mid-transit, the resulting temperature swing can destroy an entire load of perishables. Because the carrier controls the equipment, courts treat these failures as straightforward negligence.

Freight That Was Not Properly Secured

Federal rules require that tiedowns, chains, and straps collectively provide a working load limit equal to at least half the weight of the cargo.⁴ Damaged straps, missing friction mats, or empty voids where bracing should sit let freight slide during hard braking or a sharp turn. Post-accident inspections routinely surface these problems, and the responsibility sits with whoever loaded and secured the load, which is usually the carrier on less-than-truckload moves.

Driver Conduct and Hours of Service

A property-carrying driver may drive up to 11 hours after 10 consecutive hours off duty and cannot drive past the 14th consecutive hour after coming on duty, with a weekly cap of 60 or 70 hours over 7 or 8 consecutive days.⁵ Electronic logging devices record duty status automatically, and that record is often the first thing pulled when a claim turns contentious. A single hour over the limit can be enough to establish a pattern of negligent oversight, and route choices such as driving into a known severe weather warning show up in GPS logs as affirmative decisions.

What Counts as Shipper Negligence

Packaging That Cannot Survive the Trip

Long-haul freight endures constant vibration, stacking pressure, and the occasional hard stop. A 2,000-pound piece of machinery wrapped in thin plastic instead of proper dunnage and bracing often fails before the truck reaches its destination. The National Motor Freight Classification sets minimum packaging standards for less-than-truckload shipments, and freight that arrives damaged in substandard packaging generally shifts the loss back to the shipper.

Undisclosed or Mislabeled Hazardous Materials

Shippers offering hazardous materials for transportation must follow detailed rules for classification, marking, labeling, and placarding, and shipping papers must accurately identify each hazardous substance.⁶ A shipper who fails to disclose that a substance is flammable or corrosive owns the liability for any fire, spill, or contamination that follows.

Loading, Weight, and Shipper Load and Count

When the bill of lading is marked “shipper load and count,” the carrier accepts a sealed trailer without inspecting its contents, and responsibility for how the cargo is arranged inside stays with the shipper. Concentrating weight unevenly across axles or loading beyond the federal gross vehicle weight limit of 80,000 pounds for a standard five-axle combination can cause blowouts, brake failures, or fines at weigh stations.⁷ Carriers hit with overweight penalties can often push those costs back to the shipper who loaded the trailer.

How to Prove a Claim Under the Carmack Amendment

The Carmack Amendment gives the cargo owner a favorable starting position. To make out a prima facie case, you must prove three things: the goods were delivered to the carrier in good condition, the goods arrived damaged or did not arrive at all, and the dollar amount of your loss.⁸

Good condition at origin is usually established with a clean bill of lading, one carrying no notations about pre-existing damage, and reinforced by photographs at pickup. Damage or non-delivery is shown through delivery receipts with noted exceptions, receiving-dock photographs, or the simple fact that the freight never appeared. Loss amount is pinned down with commercial invoices, repair estimates, or replacement quotes.

Once you prove those three elements, the burden shifts. The carrier must then show both that it was free from negligence and that the damage resulted from one of the recognized legal defenses. It is not enough for the carrier to suggest that something else might have caused the damage. It has to prove what actually did.

One feature that catches shippers off guard is preemption. The Carmack Amendment displaces state-law claims for interstate cargo damage, so you cannot bring a separate state-court action for breach of contract, negligence, or deceptive trade practices against the carrier for the same shipment.⁹ Carmack is the avenue.

Defenses the Carrier Can Raise

Carriers are not automatically liable for every scratch and dent. Once you meet the prima facie burden, the carrier can escape liability by proving the damage resulted from one of five recognized defenses.

Act of God. Natural disasters such as hurricanes, floods, earthquakes, or lightning strikes that the carrier was powerless to avoid. The defense fails if the carrier had warning and could have taken reasonable steps to protect the freight. A tornado without warning is an act of God; driving into a storm known about for 12 hours is not.
Act or default of the shipper. Damage caused by the shipper’s own mistakes, including inadequate packaging, improper loading, or failure to disclose special handling needs. This is the defense carriers invoke most often.
Inherent vice. Deterioration caused by the natural properties of the goods themselves, such as produce ripening and spoiling or chemicals degrading at normal temperatures. The carrier must prove the damage came solely from the goods’ inherent nature and not from any failure on its part, such as ignoring the shipper’s temperature instructions.⁸
Public enemy. Losses caused by hostile military forces or acts of war. Rarely raised in modern domestic freight.
Public authority. Government action interfering with the shipment, such as a law-enforcement seizure or a quarantine order that prevents delivery.

A carrier that claims only part of the shipment was damaged by inherent vice or another defense must identify what portion of the loss it caused versus what portion the defense covers. If it cannot make that separation, the defense fails entirely.

Deadlines and Concealed Damage

Two hard deadlines matter. A carrier cannot set a claim-filing period shorter than nine months from the date of delivery, and it cannot set a lawsuit deadline shorter than two years from the date it sends you a written denial of all or part of your claim.¹⁰ These are floors. A carrier’s tariff or contract may extend them, never shorten them.

Two details about the two-year clock trip up shippers. It starts when the carrier issues a written disallowance, not when the damage occurred. A settlement offer alone does not trigger it unless the carrier explicitly states in writing that part of the claim is disallowed and explains why. A communication from the carrier’s insurer does not count as a disallowance unless the insurer identifies itself as acting on the carrier’s behalf and provides the same written notice and reasoning. Keep every piece of correspondence.

Concealed damage, the kind discovered only after unpacking sealed cartons or crates, has its own timing rule. For shipments moving under carriers that participate in the National Motor Freight Classification, the industry standard requires the consignee to report concealed damage within five business days of delivery. Notify the delivering carrier immediately, confirm in writing, request a joint inspection, and preserve the container and contents in the condition they were in when the damage was found. Missing the five-day window does not automatically kill the claim, but the burden then shifts to you to prove the damage did not happen in your possession, which means documenting who unloaded the freight, where it was stored, and what touched it. Truckload carriers outside the NMFC may have different notice periods in their tariff or bill of lading, so read those documents early.

What You Can and Cannot Recover

The Carmack Amendment limits carrier liability to actual loss or injury to the property.¹ The goal is to restore the claimant to the position they would be in if the cargo had arrived intact.¹¹ That usually means the cost to replace the goods or repair them to their pre-shipment condition, not retail markup.

Actual loss is often not what you collect. Carriers may limit their liability through released value rates, capping exposure at a set dollar amount per pound.¹ A common cap is $0.50 per pound. Under that rate, a destroyed 2,000-pound shipment yields at most $1,000, regardless of whether the goods were worth $500 or $500,000. You can avoid the cap by declaring a higher value on the bill of lading before the shipment moves and paying the carrier’s premium for the increased coverage. For high-value electronics, pharmaceuticals, or precision equipment, treat the declaration as a standard step in freight tendering rather than an afterthought.

Some remedies stay off the table because of preemption. Courts have consistently held that punitive damages and attorneys’ fees are not recoverable under the Carmack Amendment. Consequential damages such as lost profits from a production shutdown caused by a late or damaged shipment sit in a gray area. Some courts permit recovery when the carrier knew the shipment was time-sensitive, but the prevailing approach limits recovery to the physical damage to the goods themselves. If your business depends on just-in-time delivery, address delay consequences through your contract and cargo insurance rather than relying on a freight claim.

Where the Carmack Amendment Does Not Reach

Carmack covers carriers that provide transportation services, including motor carriers and freight forwarders.¹ Freight brokers, who arrange transportation but do not physically move the goods, fall outside the statute. Many shippers book loads through brokers without realizing they have no Carmack claim against the broker if the freight is damaged. The claim runs against the carrier that actually transported the shipment, and if your only relationship is with the broker, tracking down the responsible carrier and proving delivery in good condition is harder.

Carmack also applies only to interstate shipments. Purely intrastate moves within a single state are governed by that state’s own commercial and transportation laws, which vary considerably. If your freight crosses a state line at any point in transit, Carmack applies even when origin and destination sit in the same state.

What to Do Before and at Delivery

Most freight damage disputes are decided by what happened at the dock, not in a courtroom. Photograph every shipment at origin, showing packaging condition and how the freight sits on the pallet. Make sure the bill of lading accurately describes the cargo, its condition, its weight, and its value. For anything fragile, temperature-sensitive, or worth more than the carrier’s default per-pound cap, declare the full value and pay the premium.

On the receiving end, inspect freight before signing the delivery receipt. Note any visible damage directly on the receipt. Signing clean when the freight is visibly damaged weakens your prima facie case substantially. For sealed shipments, write “subject to inspection” on the receipt and open everything as quickly as possible. The five-day concealed-damage window is tight, and every day freight sits unopened makes the carrier’s after-delivery argument stronger.
