Horrific video shows bus ploughing into traffic killing four people after its driver fell asleep in the middle of a journey


This is the horrific moment four people were killed as a bus driver accused of falling asleep at the wheel ploughed into a line of stationary cars.

Dashcam footage of the shocking crash in Yeongdong, South Korea shows the out-of-control bus smashing straight into the cars, shoving them violently to one side, scattering the battered vehicles.

Initially the car filming drives in the same lane ahead of the bus, but as they approach a tunnel they move into the other one to avoid queuing traffic - and unwittingly saving their own lives.
