Driving Off with the Door Open Is a Form of Gross Negligence — The Duty to Prevent Passengers from Falling Off City Buses, Which Is Punishable Even If a Settlement Is Reached: Case Law, Obligations, and Response Measures

Written by minju.chun@aimatics.ai | Jul 31, 2026, 2:15:20 AM

At a bus stop, the doors close before all passengers have finished getting off, and the bus begins to move. A passenger falls and is diagnosed with a fracture.

This is a type of accident that repeatedly occurs among city bus operators. And it has one critical difference from ordinary traffic accidents.

Departing before the doors are fully closed is classified as one of Korea’s 12 major traffic violations. Even if the bus is covered by comprehensive insurance, and even if a settlement has been reached with the injured passenger, criminal proceedings may still continue separately. Court decisions go even further: even when the driver’s negligence is not clearly established, the bus company may still be held liable for the passenger’s injuries.

This article summarizes the three things city bus operators must understand about their duty to prevent passenger falls: court rulings, legal obligations, and practical response measures.

 

First — Court Rulings: The Company May Be Liable Even Without Clear Driver Negligence

The first thing to understand is how liability is structured. Many transportation companies assume that the company is liable only when the driver has done something wrong. In practice, however, courts apply a different standard.

Bus Company Liability for Passenger Accidents Is Close to Strict Liability

Under Korea’s Guarantee of Automobile Accident Compensation Act, the vehicle operator—typically the bus company—is generally liable when a passenger is injured or killed.

To avoid liability, the company must prove that the accident was caused by the passenger’s intentional act or attempted suicide. In practice, meeting this standard is extremely difficult.

In other words, the exemption standard for passenger accidents is far stricter than for ordinary third-party injury claims. Simply arguing that “our driver was not at fault” is not enough to avoid liability.

What Actual Court Cases Show

Published court decisions clearly demonstrate this structure.

  • A passenger suffered a fracture after falling when the bus began moving before the rear door had fully closed. The court recognized the company’s liability.
  • A passenger was boarding and climbing the steps when the driver closed the door and started moving. The passenger’s foot became trapped in the door, causing the passenger to fall onto the road. The court again recognized liability.

The common issue in both cases was the timing mismatch between the door operation and the vehicle’s departure.

Did the bus begin moving before the door was fully closed?

That brief moment becomes the central issue in determining liability.

If the passenger also violated safety rules or contributed to the accident, the compensation amount may be reduced. However, it is rare for the company’s liability to disappear entirely.

In summary, the issue a bus company can realistically dispute is not whether it has any responsibility at all, but rather:

What exactly happened at that moment?

To establish that, objective records are essential.

Second — Legal Obligations: Departing Before the Doors Are Fully Closed Is a Major Traffic Violation, and Insurance Does Not Prevent Criminal Liability

The duty to prevent passenger falls is not imposed by a single law. It is regulated through two separate legal frameworks.

When a violation involves a bus moving before the doors are fully closed, the case may follow a completely different legal path from an ordinary traffic accident.

Article 39, Paragraph 3 of the Road Traffic Act — Duty of All Drivers

All drivers must take necessary measures, including properly opening and closing vehicle doors, to prevent passengers from falling out of the vehicle.

This is the basic statutory provision governing the duty to prevent passenger falls.

A typical violation is departing while a door is open or before it has fully closed.

Article 26 of the Passenger Transport Service Act — Duty of Transportation Workers

The Passenger Transport Service Act also prohibits transportation workers from starting or operating a vehicle before its doors are fully closed.

Bus drivers therefore have two separate layers of responsibility:

  • the general duty imposed on all drivers; and
  • the additional duty imposed on passenger transport workers.

When a violation occurs, authorities may review not only the individual driver’s conduct, but also the company’s management and supervision responsibilities.

Departing Before the Doors Are Fully Closed Is One of the 12 Major Traffic Violations

This is the critical point.

Under Korea’s Act on Special Cases Concerning the Settlement of Traffic Accidents, violating the duty to prevent passenger falls—including departing before the doors are fully closed—is classified as one of the 12 major traffic violations.

The consequences are clear:

  • Criminal punishment may apply even if the company has comprehensive insurance.
  • Criminal proceedings may continue even after a settlement with the injured passenger.
  • The driver may face imprisonment for up to five years or a fine of up to KRW 20 million.

An accident that might otherwise be resolved through insurance and settlement can become a criminal case solely because the bus departed before the doors were fully closed.

If the company is also found to have failed in its safety management duties, the matter may expand to include employer liability and administrative penalties.

Third — Response: Record the Moment and Warn Before the Accident Happens

When the court rulings and legal duties are considered together, the appropriate response for transportation companies comes down to two priorities.

1. The Key Issues in Court Cases Become the Requirements for Recordkeeping

The central question in the court cases discussed above was ultimately the same:

Did the vehicle start moving only after the door was fully closed?

A company that can prove what happened and a company that cannot are placed in completely different positions, even in otherwise similar accidents.

The starting point of a legal response is therefore not a lawyer, but a reliable recordkeeping system.

Data should show, in chronological order:

  • door operation;
  • vehicle movement and departure; and
  • the passenger’s location and condition.

These records allow the company to clarify the facts during compensation negotiations and provide a basis for arguing contributory negligence by the passenger where appropriate.

We discuss the cost impact of a single passenger accident—and why CCTV footage alone may not be enough—in our article, “Can AI Prevent Passenger Falls and Door-Open Departure Accidents on Route Buses?”

2. Warn Before the Situation Becomes an Accident — Boarding and Alighting Safety Functions in Roadscope 10 DVR

A more fundamental response is to reduce the number of moments in which door operation, passenger movement, and vehicle departure become misaligned.

A.I.MATICS’ Roadscope 10 DVR integrates AI safe-driving functions with DVR and digital tachograph capabilities. Beginning with Roadscope 10, it provides two new detection and warning functions designed to address boarding and alighting risks on city buses.

Passenger Fall-Risk Warning

AI recognizes passengers’ locations and postures inside the bus and alerts the driver when a passenger may be at risk of falling.

This helps drivers recognize the danger of departing while:

  • a passenger is still standing in the aisle; or
  • an elderly or mobility-impaired passenger has not yet been seated.

Door-Entrapment Risk Detection and Warning

AI detects passengers near the bus doors and alerts the driver when it identifies a risk of entrapment.

This helps reduce situations in which:

  • the doors close before passengers have finished boarding or alighting; or
  • the vehicle begins moving before passengers are safely clear of the doorway.

It is important to clarify that these functions do not physically stop or control the vehicle.

They detect risk and notify the driver. The driver remains responsible for the final decision and vehicle operation, while AI monitors areas inside the bus and around the doors that the driver may not be able to observe alone.

Detected events are also recorded automatically.

This means that both priorities can be addressed through a single system:

  1. evidence and documentation; and
  2. accident prevention through advance warning.

Summary — Three Things to Remember About the Duty to Prevent Passenger Falls

Category Key Point
Court rulings Even when clear driver negligence is not established, the company may still be liable if a passenger is injured. The main issue that can be disputed is what exactly happened at the time of the accident.
Legal obligations
Article 39, Paragraph 3 of the Road Traffic Act and Article 26 of the Passenger Transport Service Act both apply. Departing before the doors are fully closed is one of the 12 major traffic violations, meaning insurance and settlement do not automatically prevent criminal prosecution.
Response Record door operation, vehicle departure, and passenger status in chronological order, and establish a system that warns the driver before a dangerous situation becomes an accident.

The legal consequences of passenger-fall prevention are too serious to rely solely on an individual driver’s attention.

A system that records what happened, and a system that warns before it happens—these two capabilities help protect both the company and the driver.

Frequently Asked Questions

Q. We reached a settlement with the injured passenger after a door-open departure accident. Can the driver avoid criminal punishment?

A. It is difficult.

A violation of the duty to prevent passenger falls, including departing before the doors are fully closed, is classified as one of the 12 major traffic violations under the Act on Special Cases Concerning the Settlement of Traffic Accidents.

Criminal proceedings may therefore continue regardless of whether the vehicle was covered by comprehensive insurance or a settlement was reached with the injured passenger.

A settlement may be considered during sentencing, but it does not automatically eliminate criminal liability.

Q. The driver says the door was closed before the bus started moving. Can the company still be held liable?

A. Yes.

Under the Guarantee of Automobile Accident Compensation Act, company liability is generally recognized in passenger injury cases. It is therefore difficult to avoid liability based only on the driver’s statement.

The key is objective evidence supporting that statement.

If the company has data showing:

  • when the door operated;
  • when the vehicle began moving; and
  • where the passenger was located,

it can establish the facts more accurately. If passenger negligence is confirmed, those records may also support a reduction in the compensation amount.

Q. What if the passenger rushed toward a closing door? Is the company still liable?

A. The compensation amount may be significantly reduced if the passenger is found to have been substantially at fault.

However, that determination still depends on the specific facts, including where the passenger was and what the passenger was doing at the moment the door began closing.

Video and operational data are necessary to establish contributory negligence by the passenger.

Q. How does the passenger fall-risk warning function work?

A. An in-vehicle AI camera recognizes passengers’ locations and postures and alerts the driver when it detects a potential fall-risk situation.

For example, the system may notify the driver if the bus is about to depart while:

  • a passenger is standing in the aisle; or
  • an elderly passenger has not yet been seated.

The system does not physically control the vehicle. Instead, AI monitors areas inside the bus that the driver may not be able to observe alone and provides a warning to support the driver’s decision.

Q. After a door-open departure accident, is only the driver penalized, or can the company also be held responsible?

A. The company may also face liability, separately from the driver’s criminal punishment.

As explained above, the company is generally subject to civil liability for passenger injuries.

From an administrative perspective, authorities may also review whether the company fulfilled its safety management obligations under the Passenger Transport Service Act. Depending on the findings, penalties such as administrative fines, surcharges, or suspension of operations may be considered.

A company with documented safety training, dangerous-driving monitoring, and corrective-action records may be treated differently from a company without such records.

The broader liability structure is explained in our article, “Can a Bus Company Also Be Penalized After One of the 12 Major Traffic Violations?”

Q. What records should be preserved after an accident?

A. To determine whether the bus started moving before the doors were fully closed, the following information should be available in chronological order:

  • door operation;
  • vehicle departure and movement;
  • passenger location and condition;
  • warnings delivered to the driver; and
  • the company’s safety training and corrective-action records.

Together, these records can serve as evidence that the company fulfilled its safety management duties.
