Understanding Common Carrier Law: Duties & Strict Liability

In the vast, interconnected world of logistics and travel, certain companies operate under a unique and elevated set of legal standards. These entities, known as Common Carriers, form the backbone of commerce, moving everything from commercial freight to everyday passengers. But what precisely is a common carrier, and why is its legal liability so much stricter than that of an ordinary business?

A common carrier is defined as a person or commercial enterprise that holds itself out to the general public to transport goods or passengers for compensation. Unlike a private carrier, which can choose its clients and negotiate individual contracts, a common carrier essentially offers its service to anyone willing to pay the fee, making its service public.

Typical examples of common carriers include:

• Railroads and Bus Lines
• Commercial Airlines
• Shipping Companies and Motor Freight Carriers
• Public Utilities and Telecommunications Providers (in some jurisdictions)

The Unique Duty of Extraordinary Diligence

Due to their public-facing role and the trust placed in them for public safety and commerce, common carriers are bound by legal obligations that far exceed the “reasonable care” expected of most businesses. This is often referred to as the duty of extraordinary diligence or the highest degree of care.

This stringent standard of care covers several key areas:

Table 1: Common Carrier Key Duties

Duty	Description
Duty to Serve	Must accept all passengers or goods offered for transport without unreasonable discrimination, provided there is space and the fee is paid.
Duty of Safety/Care	Must use the utmost diligence for the safe carriage of passengers and the vigilance over goods. This includes maintaining safe vehicles and properly training employees.
Duty of Reasonable Rates	Must charge rates that are fair, affordable, and non-discriminatory, often subject to regulatory approval (tariffs).

Strict Liability: The Cargo Standard

Perhaps the most defining characteristic of a common carrier, especially concerning cargo, is the principle of Strict Liability.

Strict liability means the carrier is held accountable for loss or damage to goods while in their custody, regardless of negligence. In other words, the carrier is held to a standard similar to that of an insurer. A shipper only needs to prove that the goods were delivered to the carrier in good condition and arrived at the destination damaged or did not arrive at all. The burden of proof then shifts entirely to the carrier to prove that the loss was due to a legally excepted cause.

The Five Common Law Exceptions

While strict liability is a high bar, a common carrier is not an absolute guarantor against every conceivable loss. Under common law, there are five major exceptions that can excuse a common carrier from liability for lost or damaged goods, provided the carrier can prove they were free from any negligence themselves.

1. Act of God: An irresistible superhuman cause, such as a natural disaster like a hurricane, earthquake, or sudden flooding, that could not have been foreseen or prevented.
2. Act of the Public Enemy: Damage or loss caused by an organized force at war with the government, not including criminal acts like theft or vandalism.
3. Act of Public Authority: Loss caused by a governmental action, such as the seizure of goods under quarantine laws or legal process.
4. Act of the Shipper: Damage resulting from the shipper’s own fault, such as improper packaging, misdirection, or failure to secure the load.
5. Inherent Vice or Nature of the Goods: Loss arising from a natural defect or quality of the cargo itself, such as the spoilage of perishable goods or the fermentation of liquids, provided the carrier’s negligence did not contribute to the loss.

Summary of Common Carrier Legal Responsibility

The law governing common carriers is rooted in ancient principles recognizing the carrier’s control over public commerce and safety. This body of law ensures transparency, safety, and accountability in transportation and logistics.

1. A Common Carrier must hold itself out to serve the general public for compensation, separating it from a private carrier.
2. They owe passengers and cargo a duty of extraordinary diligence, or the highest degree of care and foresight.
3. For cargo loss or damage, they are typically held to a standard of strict liability, meaning fault or negligence does not need to be proven by the claimant.
4. Liability can only be excused if the carrier proves the loss was caused by one of the five specific common law exceptions (Act of God, Public Enemy, Public Authority, Shipper’s Act, or Inherent Vice) AND that they were entirely free of negligence.
5. Federal laws like the Carmack Amendment heavily regulate liability, especially for interstate freight, and may allow carriers to limit liability under specific, legal contract terms.

Frequently Asked Questions (FAQ)

Q1: What is the difference between a Common Carrier and a Private Carrier?

A: A Common Carrier offers its services to the general public and is bound by a high duty of care and strict liability. A Private Carrier only transports goods or passengers under specific, individual contracts and can choose its clientele. Private carriers are usually only liable for damages caused by their own negligence.

Q2: Does “Common Carrier” status apply to ride-sharing services like Uber or Lyft?

A: This is a complex area of law that varies by jurisdiction. While they may appear to fit the definition, many states have enacted specific transportation network statutes that explicitly exempt them from common carrier status, though they still face significant regulatory and insurance requirements.

Q3: Can a Common Carrier limit its liability in a contract?

A: Yes, but only under specific, legally defined conditions. For instance, the Carmack Amendment allows carriers to limit liability to a value stated in the bill of lading, but only if the shipper is offered the opportunity to declare a higher value and pay a corresponding higher rate. A carrier generally cannot contractually exempt itself from liability caused by its own negligence or regulatory breaches.

Q4: When does Common Carrier liability for cargo begin and end?

A: Liability typically begins when the goods are completely delivered to and accepted by the carrier for immediate transportation. It continues until the transportation is completed and the carrier has tendered delivery to the consignee. Once transportation is complete, the carrier’s liability may reduce to that of a warehouseman (a lower standard of care) if the goods are not picked up promptly.

Q5: What standard of care is owed to passengers?

A: Common carriers owe passengers the highest degree of care and vigilance. This means they must use all human care and foresight to ensure safe transport. If an injury occurs, the carrier is presumed to be at fault unless they can prove they observed this extraordinary diligence.
