Six vehicles collided inside the Nogosan-1 tunnel on the Seoul Metropolitan Area 1st Ring Expressway this Friday, triggering a fire [1].
The incident highlights the high risks associated with multi-vehicle accidents in confined tunnel environments, where smoke and fire can quickly obstruct emergency access and trap motorists.
The collision occurred around 11:40 a.m. [1] at the tunnel entrance located in Jangheung-myeon, Yangju city, Gyeonggi Province. According to reports, the crash caused one sedan to ignite [1]. The flames then spread to a nearby SUV and partially affected a third vehicle [1].
Fire crews and police responded to the scene to extinguish the blaze and manage the resulting traffic congestion. In total, two vehicles — the initial sedan and the SUV directly ahead of it — were fully consumed by the fire [1]. A third car, positioned behind the two fully burned vehicles, was partially damaged [1].
Despite the intensity of the fire and the number of cars involved, officials said there were no injuries [1]. The pile-up included a mix of vehicle types, including a sedan and an SUV [1].
Witnesses described a scene of sudden confusion as traffic came to a standstill. One unnamed witness said, "Cars were not moving at all and I wondered what was happening, then I saw many fire trucks and ambulances arriving."
Emergency responders used hoses to battle the flames that had engulfed the vehicles [1]. The fire caused a temporary traffic jam as authorities worked to clear the wreckage and ensure the tunnel was safe for motorists to resume travel [1].

This incident underscores the critical nature of tunnel safety protocols and the rapid response capabilities of Gyeonggi Province emergency services. While the lack of casualties is a positive outcome, the fact that a single collision led to a three-car fire demonstrates how quickly hazardous conditions can escalate in enclosed transit corridors, potentially leading to mass casualties if evacuation or suppression systems fail.
