Common carriers — buses, taxis, rideshares, trains, airlines, and ferries — owe their passengers a heightened duty of care. In most U.S. states, that duty is the “highest degree of care” or “utmost care,” not ordinary reasonable care. The duty attaches from the moment a passenger boards through safely disembarking, and it is the central legal rule that makes a bus or rideshare injury case different from a typical car-crash case.

Key Facts at a Glance

Most U.S. jurisdictions impose a “highest degree of care” duty on common carriers toward their passengers, not the ordinary reasonable-care standard that governs everyday negligence.
The Texas Supreme Court reaffirmed in VIA Metropolitan Transit v. Meck that bus operators must “act as a very cautious, competent, and prudent person would act under the same or similar circumstances.”
The duty turns on and off with the passenger relationship: a carrier owes the high duty during boarding, transit, and disembarking, but only ordinary care once the passenger has safely exited the vehicle.
New York and Arizona are the two notable outliers — in Bethel v. NYC Transit Authority (1998) and Nunez v. Professional Transit Management (Arizona), the courts replaced the high-duty rule with ordinary reasonable care.
In 2024, 110 people died in school bus–related crashes — a 14% drop from the 128 deaths in 2023 — with roughly 71% of those killed being occupants of other vehicles, not bus passengers.
Commercial bus and motorcoach drivers must hold a CDL with a passenger endorsement under 49 CFR § 383.91, and carriers are bound by the Federal Motor Carrier Safety Regulations in 49 CFR Parts 390–397.
Bus passengers usually have a stronger negligence case than ordinary motorists because the elevated duty makes a breach easier to prove — the carrier had to do more than “be reasonable.”

If you were injured as a passenger on a bus, taxi, rideshare, train, ferry, or commercial flight, your case is governed by a legal rule most accident victims have never heard of — and that rule, more than any other, is what makes these cases worth filing. The law treats the carrier that sold you a ride as owing you a heightened duty of safety, well above what an ordinary driver owes everyone else on the road. Understanding that duty is the foundation of every common-carrier injury claim.

This guide is a cornerstone for the rest of our common-carrier coverage. Bus, motorcoach, rideshare, and other passenger-injury articles all link back here for the controlling legal standard, so the doctrine is explained once, in depth, with primary sources. If you are looking for vehicle-specific guidance, our spoke articles on school buses, city and transit buses, and similar carriers will point you to the relevant section here for the underlying legal rule.

We cover what a common carrier is, what the heightened duty actually requires, the few states that have rejected it, when the duty starts and ends, what evidence proves a breach, and how all of this affects the value of a claim. Throughout, the citations are to controlling case law and federal regulation — supreme court decisions, the Restatement of Torts, and the Federal Motor Carrier Safety Regulations — because these are the sources that win cases.

What Is a Common Carrier?

A common carrier is any business that holds itself out to the public to transport passengers or goods for hire on a regular basis. The defining feature is the offer of transportation to the general public for a fare — not a private arrangement between two parties. Because the carrier solicits the public and the public must rely entirely on the carrier for safe transport, the law has long treated the relationship as special, with duties beyond ordinary negligence.

In modern practice, common carriers include city and transit buses, school buses, motorcoaches, taxis, rideshare vehicles, limousines, passenger trains, ferries and water taxis, and commercial airlines. The Restatement (Second) of Torts § 314A recognizes the common-carrier-passenger relationship as a special relationship that triggers heightened affirmative duties, and the Restatement (Third) continues that recognition. The label “common carrier” is a status, not a vehicle type, and it is what triggers the rules that follow.

Two practical points matter here. First, government-operated transit — a city bus or a public school bus — is still a common carrier for purposes of the duty of care, even though suing a public entity adds procedural hurdles like short notice deadlines (see our cornerstone on suing a government vehicle). Second, rideshare services have been litigated extensively over whether they are common carriers; courts have increasingly answered yes for purposes of the duty owed to riders, while leaving the employment and indemnification questions to separate statutes.

What Duty of Care Does a Common Carrier Owe?

In the majority of U.S. jurisdictions, a common carrier owes its passengers the highest degree of care consistent with the practical operation of the system. This is sometimes called the “utmost care” standard, the “extraordinary care” standard, or the “very cautious, competent, and prudent person” standard. All three labels describe the same idea: a duty more demanding than the ordinary reasonable-care rule that governs everyday negligence.

The rule is venerable. The Texas Supreme Court traced the duty back to the early days of public transportation and explained that the common law has imposed a higher negligence duty on carriers of passengers for at least two centuries. The Court of Appeals of New York, before its 1998 about-face, applied the rule in essentially the same language: a carrier had to use “the highest degree of care” in maintaining its vehicles and operating them safely.

What does the duty look like in practice? It means the carrier is judged against what a very careful, competent operator would do — not what an average one would do. Inspecting and maintaining equipment to a higher standard than a private vehicle owner. Hiring, training, and supervising drivers to a stricter benchmark. Watching for hazards passengers cannot see. Acting promptly on a safety risk that an ordinary driver might let slide. When the carrier falls short of that elevated standard, the breach is proven.

Two limiting principles deserve attention. The duty does not make the carrier an insurer of passenger safety — a carrier is not liable for every injury, only for injuries caused by a failure to meet the elevated standard. And the duty applies to risks arising from the operation of the carriage; it generally does not cover purely independent third-party criminal acts the carrier could not reasonably have anticipated. Within those limits, the high-duty rule is a powerful tool for an injured passenger.

Which States Have Changed the Common-Carrier Rule?

A small minority of states have moved away from the heightened duty and now hold common carriers to ordinary reasonable care. The two most cited are New York and Arizona, and their decisions are worth understanding because they shape how the duty is argued nationally.

New York: Bethel v. NYC Transit Authority (1998)

In Bethel v. New York City Transit Authority, the New York Court of Appeals took the unusual step of “realigning” the standard of care for common carriers with the traditional reasonable-care rule. The court reasoned that two old rationales for the high duty — the perceived ultrahazardous nature of public transit and the passenger's total dependency on the carrier — had been eroded by modern transportation and modern negligence law. Under Bethel, a New York common carrier still owes its passengers reasonable care under the circumstances, but “reasonable” no longer means “extraordinary” as a matter of law.

Arizona: Nunez v. Professional Transit Management

Arizona reached a similar conclusion in Nunez v. Professional Transit Management. The Arizona Supreme Court vacated a judgment that had relied on the high-duty instruction, observing that the rule originated in England in the early days of public transportation and that most Arizona cases had recognized it only reluctantly. The court adopted the Restatement (Third) view: the special relationship between carrier and passenger creates broader duties (such as duties to protect from foreseeable third-party harm), but the standard of care for fulfilling those duties is ordinary reasonable care.

Why the split still matters

Even in jurisdictions that have moved to ordinary care, the carrier still owes the special-relationship duties recognized in the Restatement — a duty to act for the passenger's safety, to protect against foreseeable risks, and to come to the passenger's aid. What changed is the verbal standard, not the underlying obligation. In a New York or Arizona case, the elevated language is gone, but the carrier is still measured against what a careful operator would have done in the circumstances. In the rest of the country, the high-duty instruction itself is still available, and it materially helps a passenger prove negligence at trial.

When Does the High Duty Start and End?

The common-carrier duty attaches with the passenger relationship and ends when that relationship ends. It is not a duty owed to the world at large; it is owed to people who have become passengers of the carrier, while they are passengers.

In the typical bus case, the duty applies from the moment the passenger is in the act of boarding, throughout the ride, and through the act of safely disembarking. Once the passenger has safely exited the vehicle at the chosen destination, the contract to transport ends and the former passenger becomes a pedestrian. From that point, the carrier owes only ordinary care, the same duty everyone owes everyone else. West Virginia's high court applied that framework in Hayes v. Kanawha Valley Regional Transportation Authority, holding that the transit authority's high duty ended when the passenger safely stepped off the bus.

The boundary is where most boarding and disembarking cases are fought. A passenger reaching for the handrail, climbing the steps, or stepping down at a stop is still owed the heightened duty — and these are the moments when slips, falls, and being struck most often happen. A school child crossing the street after stepping off a school bus, on the other hand, may be outside the high-duty window the moment the door closes and the bus pulls away, depending on the state. The exact line is fact-specific, and it often becomes the most important factual question in the case.

How Is Breach of the Common-Carrier Duty Proven?

Proving a breach requires showing that the carrier did not meet the elevated standard the law imposes. The same categories of evidence appear in nearly every case: driver fitness, vehicle condition, operational practices, and the carrier's response to known risks.

Driver qualification and training. Did the driver hold a valid CDL with a passenger endorsement under § 383.91? Was training documented and current? Did the carrier follow up on prior complaints or incidents?
Hours of service and fatigue. Commercial passenger drivers are bound by federal hours-of-service limits; violations are powerful evidence of a fatigue-related breach.
Vehicle inspection and maintenance. The carrier must inspect and maintain its vehicles under Federal Motor Carrier Safety Regulations; missed brake inspections, ignored defect reports, and out-of-service violations all support a breach.
Operational practices. How fast was the driver going relative to road and weather? Was the route appropriate for the vehicle? Were stops made safely and signaled properly?
Response to known risks. Did the carrier act when it learned of a hazard — a worn handrail, a problem stop, a complaint about the driver — or did it ignore it until someone was hurt?

The records that prove (or disprove) each of these live with the carrier: driver-qualification files, log records, maintenance logs, incident reports, telematics, and onboard video. They can be discarded on a routine schedule, so a written preservation demand is one of the first things experienced counsel sends after a serious common-carrier injury. The same urgency applies in our coverage of trucking liability evidence, and for the same reason: the proof that wins the case is in the operator's hands.

Who Can Be Held Liable When the Carrier Is at Fault?

Liability in a common-carrier case typically reaches well beyond the driver. The defining purpose of the high-duty rule is to make the carrying organization — not just the individual operator — answer for the safety of paying passengers. That principle reaches a familiar list of defendants.

The carrier (operator). Whether a private bus company, motorcoach operator, taxi or rideshare company, transit authority, or school district, the carrier is responsible for its drivers' conduct on the job and for its own system-level decisions about training, hiring, vehicle maintenance, and route safety.
The driver. Directly liable for negligent operation. Often the carrier is responsible for the driver's acts under respondeat superior, so the driver and the carrier are usually sued together.
A maintenance contractor. Vehicles serviced by a third party can produce liability for that contractor where defective repair caused the failure.
A manufacturer. Defective brakes, tires, or other components can support a product-liability claim against the manufacturer.
Other motorists or third parties. A carrier crash can be caused or worsened by another driver's negligence, and that party may share fault.
A government entity. Where the carrier is public (a transit authority, school district, or municipal fleet), the public defendant is governed by the state's tort-claims act — see suing a government vehicle for the procedural rules and notice deadlines.

Identifying every responsible party is essential because each may carry separate insurance, and because the procedural rules — deadlines, notice requirements, immunities — can differ defendant by defendant. The garbage truck cornerstone walks through the same public/private analysis on the goods-carrier side; the structure is the same for passenger carriers.

What Compensation Can Common-Carrier Passengers Recover?

Injured passengers can generally recover economic damages (medical bills, future care, lost income, lost earning capacity), non-economic damages (pain and suffering, loss of enjoyment of life), and — in the most egregious cases — punitive damages. In a fatal case, surviving family members may pursue wrongful-death and survival claims under state law.

The heightened duty matters here, too, in two practical ways. First, because breach is easier to prove than under ordinary negligence, the liability case is stronger, which moves settlement value upward. Second, because carriers typically maintain substantial insurance — motorcoaches alone face FMCSA minimum coverage in the millions, depending on capacity — there is usually meaningful coverage to pay a fair recovery. Our overview of damages in truck accident cases details how each category is calculated; the analytical framework is the same for passenger carriers, with adjustments for the type of injury and the available coverage.

Punitive damages deserve a special note in common-carrier cases. Because the carrier's elevated duty includes affirmative obligations to recognize and respond to known hazards, a documented pattern of ignoring safety — prior complaints, repeated maintenance failures, knowing violations of federal rules — can support a punitive claim on top of compensatory damages. Punitive awards are governed by state law and carry heightened standards (often gross negligence or willful and wanton conduct), but a high-duty carrier that knowingly cut corners is exactly the conduct punitive damages were designed to address. Catastrophic injuries deepen the stakes; see our guide on catastrophic truck and bus injuries for the cost-of-care side of the analysis.

Frequently Asked Questions

What is a common carrier in plain English?

A common carrier is any business that offers transportation to the general public for a fare on a regular basis. The label covers city and transit buses, school buses, motorcoaches, taxis, rideshare vehicles, trains, ferries, and commercial airlines. The defining feature is the public offer of transport for hire — not a private agreement between two parties.

What is the highest degree of care?

It is the elevated standard the law applies to a common carrier toward its passengers in most U.S. states. The carrier must act as a “very cautious, competent, and prudent person” would in the same circumstances — a standard above ordinary reasonable care. It does not make the carrier an insurer of safety, but it does make a breach materially easier to prove.

Is a rideshare driver a common carrier?

Increasingly, yes. Courts in multiple jurisdictions have held that rideshare services holding themselves out to the public for fares meet the definition of a common carrier for purposes of the duty owed to riders. The carrier-status question is separate from the employment question (independent contractor vs. employee), which is governed by other statutes and is litigated separately.

Does the high duty apply to school buses?

Generally yes. School buses transporting students for the district are common carriers and owe the heightened duty during boarding, transit, and disembarking. The duty typically does not extend to a child crossing the street after safely stepping off the bus, but where the injury occurs in the loading or unloading zone, the high duty is normally in force.

If I was hurt after getting off the bus, does the heightened duty still apply?

Usually only until you have safely disembarked. Once the passenger has safely exited the vehicle at the chosen destination, the relationship ends and the carrier owes only ordinary care. Whether you had “safely disembarked” in a given case can itself be the key factual question, so the boundary is fact-specific.

Are buses and rideshares regulated by the federal government?

Many are. Interstate motorcoach and bus operators are regulated by the FMCSA, including driver licensing under 49 CFR § 383.91, hours of service, and the carrier-safety provisions of 49 CFR Parts 390–397. Local transit and taxi/rideshare regulation varies by state and city, but federal rules still apply where the operator crosses state lines or carries enough passengers to meet the federal threshold.

Does the duty change if the carrier is a city or other government entity?

The substantive duty (the standard of care) is the same, but procedural rules change dramatically. A public carrier is shielded by sovereign immunity to the extent the state's tort-claims act allows, and the act typically imposes short notice deadlines — sometimes as little as 90 days — that ordinary injury cases do not have. Our cornerstone on suing a government vehicle explains the procedural framework.

Why does the common-carrier rule make my case stronger?

Because breach is easier to prove. Under ordinary negligence, the plaintiff must show the defendant did not act as a reasonable person would; under the common-carrier rule, the plaintiff need only show the carrier did not act as the most careful operator would. The elevated standard moves more conduct over the line into actionable negligence, which strengthens both the liability case and settlement leverage.

What evidence is most important in a common-carrier case?

The carrier's records: driver-qualification files, hours-of-service logs, maintenance and inspection records, incident reports, prior complaints, onboard camera footage, telematics, and route data. Much of this is in the carrier's exclusive control and can be lost on routine schedules, so a written preservation demand should go out quickly.

How quickly should I contact a lawyer after a bus or rideshare injury?

As soon as possible. If the carrier is public, a notice-of-claim deadline measured in months may already be running. If the carrier is private, evidence can still vanish in weeks. Either way, early representation is the most reliable protection. A free consultation carries no cost or obligation.

The Bottom Line on the Common-Carrier Duty

The common-carrier duty is one of the oldest and most powerful rules in American tort law. It exists because passengers, having paid for transport and surrendered control of their safety to the carrier, deserve more than the ordinary protections of a stranger on the road. In most states, that translates into a duty of the highest degree of care — a standard that gives injured passengers a real, structural advantage in proving negligence.

For anyone hurt as a passenger on a bus, rideshare, taxi, train, ferry, or commercial flight, the rule is the place to start. Knowing whether your state still applies the heightened duty, when the duty attached and when it ended in your particular trip, and what records prove the breach is the difference between a strong case and a lost one. Contact us for a free consultation to be connected with a common-carrier injury lawyer who can apply this framework to your facts.

Two things bear repeating before you act. First, the high-duty rule is a powerful tool, but it does not run on its own — it has to be invoked, applied to the facts, and proven with the carrier's records, which means moving quickly while those records still exist. Second, the procedural overlay matters as much as the substantive rule. A public carrier triggers a state tort-claims act with a notice deadline that can be a fraction of the ordinary statute of limitations, and missing that deadline forfeits the claim no matter how strong the duty-of-care case would have been. Treat both as urgent, and the heightened duty does the work it was designed to do.
