The footage below, filmed through a dashcam on a highway in South Korea, proves how even the most careful of drivers can sometimes find themselves in the midst of a fatal crash.
A Hyundai Azera driver blacked out after hitting a car in another accident (not seen in this video); the Azera continued down a hill and onto the highway where it smashed into an oncoming truck.
The three people onboard the Azera died, while the truck driver was left critically injured and the people inside the car with the dashcam came out with minor injuries.
