One person was killed in a five-vehicle collision Monday afternoon on the Pyeongtaek-Siheung Expressway in Danwon District, Ansan, Gyeonggi.
The accident occurred around 12:20 p.m. near the Namansan Interchange on the Siheung-bound side of the expressway, according to police.
The crash involved five vehicles: a passenger car, a 3.3-ton truck, two 25-ton trucks and a trailer.
Police said the pileup began when a 25-ton truck rear-ended a Hyundai Mighty cargo truck and a tanker truck in sequence. A trailer and a passenger car were subsequently caught in the crash.
The 25-ton truck driver was found unresponsive at the scene and later pronounced dead at a hospital. Two other drivers — of the car and one of the trucks — sustained minor injuries and were also taken to a hospital.
As of 3 p.m., tow operations were still underway and traffic remained backed up in the area. The expressway operator advised drivers to take a detour via the Yeongdong Expressway.
Police and fire authorities plan to investigate the exact cause of the accident once the scene is cleared.
