Bundang

A serious road accident in South Korea's Seongnam city has left dozens of people injured after a public bus crashed into 31 other vehicles during the morning rush hour. The chain collision took place in the Bundang district, south of Seoul, involving several buses, a truck and dozens of passenger cars.

The accident happened at approximately 7:34 a.m. local time near a traffic junction in Yatap-dong. The bus struck vehicles waiting at a traffic signal before continuing forward and crashing into a central road barrier.

The scale of the collision created a major emergency response, with damaged vehicles spread across the road and passengers and drivers requiring medical attention.

Injury figures reported as rescue operation continued

Initial figures from South Korean authorities put the number of injured people at 48. A later report based on fire department information gave a higher figure of 57 people receiving treatment, including nine with serious injuries. None of those injuries were reported to be life-threatening in that account.

The difference in the reported totals appears to reflect updates during the emergency response. The exact final number of injured people may become clearer as authorities complete their assessment.

The bus driver was also injured and had to be rescued from the damaged vehicle before being taken to hospital. Several passengers and people travelling in the other vehicles were among those hurt.

Emergency responders established a medical station near the crash site to assess victims and arrange treatment. Fire and rescue personnel worked alongside police to manage the situation and assist those trapped or injured.

Thirty-two vehicles involved in the collision

The crash involved a total of 32 vehicles, including the bus that triggered the chain collision. The group consisted of four buses, one cargo truck and 27 passenger cars.

The vehicles were caught in the collision as traffic waited near the signal. The impact continued along a stretch of road before the bus finally stopped against the median barrier.

Images from the scene showed extensive damage to the front of the bus, with its windshield shattered and the vehicle resting against the central divider. Other cars involved in the accident also suffered damage.

The large number of vehicles involved made the rescue and traffic-management operation more complicated. Authorities had to secure the area, assist injured people and move damaged vehicles from the roadway.

Driver reportedly told police that brakes failed

One of the main questions facing investigators is what caused the bus to lose control and strike so many vehicles.

The driver, a man in his 60s, reportedly told police that the brakes had not worked. This statement has made possible brake failure an important part of the investigation, but authorities have not yet established it as the confirmed cause.

A breathalyser test did not detect alcohol in the driver's system. Police are expected to examine the circumstances surrounding the journey and determine whether any mechanical fault or other factor contributed to the collision.

Investigators plan to study recordings from the vehicle's onboard black-box system and CCTV footage from the surrounding area. These records could help establish the bus's speed, movement before the impact and the sequence in which the vehicles were struck.

The investigation will also need to determine whether the bus had any mechanical problems before the accident and whether the vehicle's braking system was functioning properly.

Morning traffic disrupted in Seongnam

The crash occurred during one of the busiest periods of the day, when commuters were travelling to work and school. The accident caused disruption around the Bundang area as emergency teams took control of the scene.

Traffic movement was temporarily restricted while rescue workers treated victims and authorities arranged for damaged vehicles to be removed. The restrictions added to congestion on nearby roads.

The incident also raised concerns about the safety of public transport and the condition of vehicles operating on busy urban routes. A single serious failure involving a large passenger vehicle can have consequences for many road users, particularly at junctions where traffic is stopped.

However, investigators will need to establish the technical and operational facts before drawing conclusions about responsibility or any possible safety violations.

Investigation to establish the cause

The South Korean authorities now face the task of reconstructing the collision and determining why the bus continued into a line of vehicles.

Black-box data, CCTV recordings, vehicle inspections and statements from the driver and witnesses are expected to play an important role. Investigators may also examine maintenance records and the bus's recent operating history if a mechanical problem is suspected.

For now, the reported brake failure remains the driver's account rather than a confirmed finding. The investigation will determine whether the accident resulted from a technical defect, a driving-related issue or another factor.

The crash has highlighted the risks that can arise during busy commuting hours when large vehicles share crowded roads with private cars and commercial transport. With dozens injured and 32 vehicles involved, the incident has become a major road-safety investigation in the country.

Further details are expected as police and fire authorities complete their assessment of the victims, inspect the damaged vehicles and establish the sequence of events.
