Trailer Driver Injured in 27-Ton Truck Engine Failure Accident

South Korean authorities have confirmed that a freight truck accident occurred on the Pyeongtaek–Jecheon Expressway near the Cheondeungsan No. 3 Tunnel on April 19, 2026, resulting in one driver being hospitalized with leg injuries. The incident, which took place in the Pyeongtaek-bound lanes, prompted a full closure of that direction while emergency crews responded and investigators began assessing the cause.

According to initial reports from YTN and corroborated by local traffic police, the 27-ton truck experienced an engine malfunction shortly before entering the tunnel, leading to a loss of control and subsequent collision. The driver of the trailer reportedly evacuated the vehicle safely but began experiencing pain in the lower limbs and was transported to a nearby medical facility for evaluation and treatment. No other injuries were reported among passing motorists or nearby personnel.

Emergency services arrived at the scene within minutes, securing the area and initiating traffic diversion protocols. The Pyeongtaek-bound lanes remained closed for several hours as investigators examined the vehicle, reviewed dashcam footage from nearby cars, and interviewed witnesses. Authorities have not released the identity of the driver or the name of the logistics company operating the truck, citing ongoing investigative procedures.

Police officials stated that preliminary inspections suggest mechanical failure as a possible contributing factor, though they emphasized that the investigation remains open and that other elements — including road conditions, vehicle maintenance records, and driver fatigue — are being reviewed. No citations or charges have been filed at this stage.

The Cheondeungsan No. 3 Tunnel, a key segment of the expressway connecting industrial zones in Pyeongtaek to inland logistics hubs, sees frequent heavy vehicle traffic. Officials noted that while tunnel accidents are relatively rare due to strict monitoring systems, incidents involving large freight vehicles can pose significant risks due to limited maneuverability and extended stopping distances.

As of the latest update, traffic flow in the Pyeongtaek-bound direction has been restored, though authorities continue to advise drivers to remain alert for possible residual delays or inspection checkpoints. The truck involved in the accident has been removed from the scene and is undergoing forensic mechanical analysis.

This incident adds to a growing national conversation about commercial vehicle safety on South Korea’s expressways, particularly concerning aging fleets and maintenance compliance. Transportation safety advocates have previously called for stricter inspection protocols for vehicles over 20 tons, especially those regularly using mountainous or tunnel-heavy routes like the Pyeongtaek–Jecheon corridor.
