In this episode we reveal disasters caused by drivers making misjudgements at junctions, from the lorry sent flying in a collision with another big rig in Washington State, USA, to a horrifying head-on smash between two vehicles on a blind bend near Harrogate.We witness the dangers of pile ups, including a massive combination of collisions in Bulgaria on an icy road at night, and a pile up caused by a long lorry performing a U turn on a motorway in Thailand.We also see crashes caused by bad driving in luxury cars, like the hydroplaning Lamborghini that took out a Peugeot before smashing into a central reservation in Russia, and the driver of a Ferrari in Dubai who lost control after accelerating too hard and ended up heading head first into a wall.Plus, we reveal how objects that don't normally belong on a motorway can lead to major accidents, and why undertaking can lead to really dangerous driving disasters.
