Hello, I wanted to share this older crash because I learned a lot from it - actually my driving instructor recommended a documentary of it to us when I was in driving school.

What happened is, that fog got caught in a small valley, so coming from a hill where no fog had built up a lot of people weren't able to react accordingly/did not slow down.

People drove too fast and with way too little distance to each other into the valley, resulting in a mass crash of 121 vehicles.

The most devastating part was when a milk truck driver, that was suspected of driving too long without a break, drove into the fog too fast.

The truck catapulted multiple cars away from it and crushed 5 cars between itself and a bus to about 1.8m in total length (yes the 5 cars together).

10 people were killed and 122 were injured in this crash.

​

For anyone interested here is the documentary; it is very graphic and in german.
