Motor Carrier Liability: Who Pays When Freight Is Damaged?

When freight arrives damaged, short, or not at all, the question of who pays is not left to negotiation — it is governed by federal law. The Carmack Amendment makes motor carriers strictly liable for freight damage with very few exceptions. Understanding how this liability works is essential for every carrier, from solo owner-operators to large fleet operations.

The Carmack Amendment: Carrier Liability Under Federal Law

The Carmack Amendment (49 U.S.C. 14706), originally enacted in 1906, is the federal law that governs motor carrier liability for freight loss and damage in interstate commerce. It establishes a simple but powerful rule: the carrier that accepts freight is liable for its safe delivery.

Under Carmack, a shipper only needs to prove three things to establish a claim: (1) the goods were delivered to the carrier in good condition, (2) the goods arrived at the destination damaged or did not arrive at all, and (3) the amount of damages. Once the shipper proves these three elements, the burden shifts to the carrier to prove it is not liable under one of the five recognized defenses.

This strict liability standard means carriers are essentially insurers of the freight they haul. You do not need to be negligent to be liable — if the freight is damaged in your possession, you pay unless you can prove one of the narrow exceptions applies. This is why cargo insurance, while not federally required, is a practical necessity for every for-hire carrier.

Carmack Applies Even Without a Written Contract

The Carmack Amendment applies to all interstate freight transportation by motor carrier, regardless of whether there is a written contract between the parties. The bill of lading is the contract of carriage. Once you sign the BOL and take possession of the freight, Carmack liability attaches. Verbal agreements, handshake deals, or the absence of a formal contract do not change this.

The Five Carrier Defenses

A carrier can avoid Carmack liability only by proving the damage was caused by one of these five recognized exceptions. The burden of proof is on the carrier:

1

Act of God

Natural disasters that could not have been anticipated or avoided — tornadoes, earthquakes, floods, lightning strikes. Weather that is foreseeable (like winter storms in January) is harder to claim as an act of God. The carrier must show the event was extraordinary and unavoidable.

2

Act of Public Enemy

Damage caused by foreign enemies or acts of war. This is an extremely rare defense in modern trucking. Standard theft does not qualify — it must be an act by a recognized public enemy or foreign nation.

3

Act of the Shipper

Damage caused by the shipper's own actions — most commonly improper packaging, incorrect labeling, concealed defects, or failure to disclose the nature of the goods. If the shipper loaded the trailer (shipper load and count), the carrier may argue the shipper's loading caused the damage.

4

Authority of Law

Damage resulting from government action — a law enforcement seizure, quarantine order, or regulatory confiscation. If the government orders the freight destroyed or detained, the carrier is not liable.

5

Inherent Nature of the Goods

Damage caused by the natural characteristics of the freight itself — perishable food spoiling naturally, live animals dying of natural causes, or goods that are inherently fragile. The carrier must show the damage was inevitable regardless of how carefully the freight was handled.

How Freight Damage Claims Are Filed

The freight claim process has specific timelines that both shippers and carriers must follow:

Discovery — Damage is discovered at delivery (or within 5 days for concealed damage). The receiver notes damage on the delivery receipt and BOL. Photographs are taken.

Written claim filed (within 9 months) — The claimant (shipper or receiver) must file a written claim with the carrier within 9 months of delivery. The claim must state the amount of damages and include supporting documentation.

Carrier acknowledges (within 30 days) — The carrier must acknowledge receipt of the claim within 30 days.

Carrier responds (within 120 days) — The carrier must pay, decline, or make a settlement offer within 120 days of receiving the claim.

Lawsuit deadline (2 years) — If the claim is denied, the claimant has 2 years from the date of denial to file a lawsuit. If the carrier fails to respond, the 2-year period runs from the date the carrier should have responded.

Respond to Every Claim Within the 120-Day Window

Even if you believe the claim is baseless, respond formally within 120 days. Failing to respond does not make the claim go away — it simply removes your ability to dispute the claim amount and strengthens the claimant's position if the dispute goes to court. Acknowledge receipt, investigate, and provide a written response with your decision.

Released Value Rates and Liability Limits

Carriers can limit their liability through released value provisions in the bill of lading. This is a negotiated arrangement where the shipper agrees to declare a lower value for the freight in exchange for a lower freight rate. If the freight is damaged, the carrier's liability is capped at the declared value rather than the full actual value.

For a released value provision to be enforceable, the carrier must: (1) maintain a published tariff or written agreement with the released rate, (2) give the shipper a reasonable opportunity to choose between full liability and the released rate, (3) obtain the shipper's written agreement to the released value, and (4) offer a genuine reduction in the freight rate as consideration for the reduced liability.

If any of these steps is missing, courts will generally enforce full Carmack liability regardless of what the BOL says. Many freight claims are won or lost on whether the released value process was properly followed — making documentation critical.

The Bill of Lading's Role in Freight Claims

The bill of lading is the most important document in any freight damage dispute. It serves as the contract of carriage, the receipt for the goods, and the primary evidence of the freight's condition at pickup. Every carrier should treat the BOL with the same care as a legal contract — because that is exactly what it is.

At pickup, inspect the freight carefully. Note any pre-existing damage, improper packaging, or discrepancies between the BOL description and the actual freight. Write exceptions directly on the BOL before signing. At delivery, note the condition of the freight and have the receiver sign for it. These notations are your first line of defense in any claim dispute.

Shipper Load and Count (SLC)

When the BOL is marked “Shipper Load and Count,” it means the shipper loaded and sealed the trailer without the carrier inspecting the contents. This notation helps the carrier argue that any shortage or concealed damage may have been caused by the shipper's loading, not by anything the carrier did. Always note SLC on the BOL when the shipper loads the trailer and the carrier does not verify the contents.

Protecting Your Carrier from Damage Claims

While you cannot eliminate Carmack liability, you can significantly reduce your exposure:

Photograph every load at pickup and delivery — Timestamped photos from multiple angles. This is your strongest evidence. Many claims evaporate when the carrier produces clear photos showing the freight's condition.

Note all exceptions on the BOL — Any pre-existing damage, packaging issues, or discrepancies must be written on the BOL at pickup. Do not sign a clean BOL if the freight has any issues.

Secure freight properly — Follow FMCSA cargo securement rules (49 CFR Part 393). Improper securement is negligence, and negligence eliminates most of your defenses.

Maintain proper reefer temperatures — For temperature-sensitive freight, document temperature settings at pickup and download reefer data showing continuous temperature maintenance throughout the trip.

Carry adequate cargo insurance — Your cargo policy pays claims on your behalf. Without it, freight claims come directly from your operating capital. Standard coverage is $100,000; consider higher limits for high-value freight.

Broker vs Carrier Liability for Freight Damage

A common source of confusion: who is liable when freight brokered through a freight broker is damaged? The general rule is clear — the carrier that physically transported the freight bears Carmack liability. Brokers are not carriers and are generally not liable under Carmack.

However, brokers can be liable for negligent carrier selection — if the broker hired a carrier with known safety issues, lapsed insurance, or a history of freight damage, the broker may share liability. This is why responsible brokers check carrier SAFER records, CSA scores, and insurance before tendering freight.

Keep All Rate Confirmations and BOLs for 2+ Years

The statute of limitations for freight claims is 2 years from the date of denial. Keep every rate confirmation, BOL, proof of delivery, and claim correspondence for at least 2 years after delivery. Digital storage is fine, but make sure the documents are backed up and easily retrievable. Losing documentation in a dispute is the same as losing the dispute.

How Our Team Helps Carriers Manage Liability

At O Trucking LLC, we help carriers minimize freight damage exposure through proper documentation and process:

BOL documentation guidance

We guide drivers on proper BOL procedures — noting exceptions at pickup, photographing loads, and ensuring delivery documentation is complete. Good documentation at the time of the event prevents costly disputes weeks later.

Broker and shipper vetting

We verify broker legitimacy and shipper requirements before accepting loads. Knowing the freight type, value, and special handling requirements upfront lets the carrier prepare properly and avoid loads that exceed their insurance coverage or handling capabilities.

Claims process coordination

When a damage claim does occur, we help carriers gather and organize the documentation needed to respond — photos, BOL copies, rate confirmations, and trip records. A well-documented response filed within the 120-day window is critical for resolving claims fairly.
