In this episode we reveal disasters caused by drivers drifting across the carriageway, from the worker who crashed a tanker full of fuel into a group of parked cars in Thailand to the driver in Norway who veered directly into the path of an oncoming HGV.

We witness the dangers of the hard shoulder, including a rescue worker in Texas who came face to face with a flying SUV, and a motorist who ended up rear-ending a roadworks vehicle in San Diego, California.

We also see what happens when exiting the motorway goes wrong, like the car that got shunted up the motorway in Staffordshire after pulling in front of a huge lorry, and the motorist in Malta who got their exit strategy all wrong and flipped upside down onto their roof.

Plus, we reveal why it pays to expect the unexpected, and what can happen when animals stray onto the highway.

In this episode we reveal disasters caused by drivers making high risk manoeuvres, from the man in the USA who attempted to pass a truck via a grass verge and ended up getting his car totalled, to the driver in China who attempted to move his car through a small gap and got it flipped onto its roof.

We witness the dangers of level crossings, including a truck that got hit by a freight train in Oregon after it got stuck attempting a turn as the barriers came down, and an oversized vehicle in Kansas that destroyed a lighting rig at a crossing as it attempted to pass underneath.

We also see what can go wrong when driving in the snow, like the truck that took out a car as it skidded sideways down a motorway in Russia, and what happened after a vehicle skidded towards a massive forty car pile-up in West Virginia.

Plus we reveal traumatic tales of towing trailers, and what can happen when tractors get into accidents on the highway.
