The bus, driven by a man in his 60s, collided with some 32 vehicles including a truck, four other buses and 27 passenger cars near an intersection in Yatap-dong, Bundang in Gyeonggi Province at around 7:34 a.m.
It plowed into the vehicles over a stretch of roughly 100 to 150 meters in a chain-reaction crash before coming to a stop after hitting a traffic barrier.
Nine people including the bus driver were seriously injured, while the others sustained minor injuries. None of the injuries were considered life-threatening, and all those injured were reported to be in stable condition.
Many of those injured were passengers on the buses involved in the crash.
The driver told investigators that the brakes had failed. An initial breath test showed that he had not been drinking, but police plan to check whether he had taken drugs.
Police are investigating the exact cause of the crash.
