Seongnam Bundang City Bus Pile-Up, South Korea: Route 340 Bus Hits 32 Vehicles at a Morning Rush-Hour Signal, 57 Injured in the First Count and 70 by Evening, No Deaths Reported; Driver Says the Brakes Failed, Police Check the Brakes, the Pedals and Drugs

What happened

At about 7.34 am local time on Wednesday 11 November 2026, a Seongnam city bus, Route 340, ran into vehicles waiting at a signal on Pangyo-ro in Yatap-dong, Bundang district, Seongnam, Gyeonggi province, South Korea. It was the morning rush hour, and the bus was carrying passengers. Reports say it hit vehicles one after another over a stretch of 100 to 150 metres, took a traffic light and a utility pole down, and stopped only when it struck the central median barrier. Yonhap, through The Korea Times, counts 32 vehicles hit, not counting the bus itself: four other buses, one cargo truck and 27 passenger cars. That is about 4.04 am in India.

No death is reported in any outlet we opened. The injured count kept rising through the day. Early reports said 34 and then 48 were hurt, with 6 seriously. Yonhap and fire authorities later gave 57, with 9 seriously and 48 slightly. By the evening, News1 and Seoul Shinmun reported 70 injured, 10 seriously and 60 slightly, and none in danger of dying. Seoul Shinmun says 55 people were taken to hospitals and 15 walked in for treatment, and that firefighters freed the driver, who was trapped. The driver, a man in his 60s, told police that the brakes did not work. A breath test at the scene found no alcohol. Police are checking whether the brakes were defective, whether the pedals were misused and whether the driver had taken drugs, and they are going through the bus’s dashcam and nearby CCTV. None of this has been established. We use no names for the driver or anyone hurt.

What the reports say

• When: About 7.34 am local time (KST) on Wednesday 11 November 2026, during the morning rush hour (Yonhap via The Korea Times, Weekly Kyunghyang, Pressian, Seoul Shinmun). That is about 4.04 am IST and 10.34 pm UTC on Tuesday 10 November.
• Where: Pangyo-ro in Yatap-dong, Bundang district, Seongnam, Gyeonggi province. Seoul Shinmun puts the impact zone between the Areum and Beolmal intersections; some outlets say Imae-dong or name only the Beolmal intersection.
• The bus: A Seongnam city bus on Route 340, driven by a man in his 60s. The reports do not name the operating company or say how many passengers were on board; the injured count says many were.
• Vehicles hit: 32 vehicles in total in most outlets: four other buses, one cargo truck and 27 passenger cars (Yonhap via The Korea Times, Weekly Kyunghyang, Pressian). Seoul Shinmun counts 32 including the Route 340 bus. Early reports said 16 or 17. The bus rear-ended vehicles waiting at a signal, hit a traffic light and utility pole and stopped against the median barrier.
• Injured: The count moved from 34 (early) to 48 (6 serious) to 57 (9 serious, 48 slight) to 70 (10 serious, 60 slight, News1 and Seoul Shinmun, late on 11 November). Most were bus passengers with abrasions and bruises. No death is reported and the injured are not in danger of dying.
• Rescue: Fire authorities sent 45 personnel and 18 vehicles in the first report and 88 personnel and 33 vehicles in the later count (Newdaily, Seoul Shinmun, The Korea Herald). Firefighters freed the trapped driver. Both directions of Pangyo-ro were closed for a time and all closures were lifted by about 10 am.
• The driver’s account: The driver told police the brakes did not work (Yonhap via The Korea Times, Weekly Kyunghyang, Pressian). The breath test found no alcohol. The Korea Herald says police suspect a brake malfunction but call it unconfirmed.
• Police checks: Police are checking dashcam and CCTV footage for a possible brake defect and for possible pedal misuse, and plan to check whether the driver had taken drugs (Seoul Shinmun, Yonhap). No result is reported.

Where reports differ and what we do not know

• Number injured: 34, 48, 57 and 70 were all reported on the same day as counts were revised. The last two figures come from fire-authority tallies reported by Yonhap and by News1 and Seoul Shinmun. We use 70 as the latest count and 57 as the figure most outlets carried in the morning.
• Serious injuries: 6 (early), 9 (Yonhap, Korea Times, Weekly Kyunghyang, Pressian) and 10 (News1, Seoul Shinmun). Some reports include the driver in the serious group.
• Number of vehicles: 32 vehicles besides the bus (Yonhap via The Korea Times) against 32 including it (Seoul Shinmun). Early reports said 16 or 17 vehicles and 34 injured. One headline said 32 buses, which the body of the same report contradicts.
• Place: Yatap-dong (most outlets), Imae-dong (News1) and the stretch between the Areum and Beolmal intersections on Pangyo-ro (Seoul Shinmun). The pin on our map is at the area level.
• Cause: The brake failure comes from the driver’s own account. Police have not confirmed it and are also checking pedal misuse and drugs. We do not say what caused the crash.
• Not yet reported: The bus operator, its maintenance and inspection record, the last brake service, the bus’s speed, the CCTV results, the drug test result and any charge against the driver.

What this case teaches

A city bus is heavy and full of people, so a failure at the front of a traffic queue ends up in the lap of everyone behind. What the reports show is simple: a bus was moving fast enough to hit one vehicle after another over about 150 metres and to take a traffic light down with it, at a time when roads are full and passengers are standing and sitting in the first rows. It is too early to say whether the brakes, the driver’s foot or something else was the cause, and the police have not said. We repeat only what the driver says and what the checks are looking at.

For passengers, the lessons are the ones that apply on any city bus. Sit with your back against the seat if you can, hold the rail with both hands when the bus is moving fast or the driver shouts, keep clear of the front glass and the first row, and keep phones and bags out of your hands. After a crash, get off by the nearest door or emergency window if there is smoke or fuel and move to the pavement away from moving traffic. For other drivers in a queue at a signal, keep the handbrake off but your foot ready, look in the mirror when you stop and leave a gap if the lane beside you is open. Our guides cover what to do after a road collision as a driver or passenger, safety in buses, trains and metros, road accident first aid before the ambulance arrives and why the first hour after a crash matters.

Other bus cases on the site include the BEST bus that lost control and hit two cars at Wadala signal in Mumbai, the Belapur bus pile-up where brake failure was investigated, the Calgary bus pile-up and the coach rollover on the A3 motorway in Croatia. We read the reports up to the evening of 11 November 2026 and found no inspection result yet. We will update this post when one is published.
