This dashcam footage from Australia shows a nasty pile-up after drivers react late to a seemingly sudden traffic jam on a five-lane highway.

The video shows a couple of drivers braking hard (there even appears to be a little cloud of smoke, likely from one of the vehicles locking up its brakes) as traffic forms in the lane on the extreme left.

The person behind the wheel of the silver Toyota Camry fails to stop in time, clattering into the vehicle in front (which, in turn, shunts into the Camry in front of it).
