As a cross-country truck driver said ...

When you pass an 18-wheeler or it passes you, remember the tires are mostly bald and the brakes don't work.

Worse than that: You are driving in Russia and you see a truck.

I'm going to be ethnically insensitive: Considering the video is Russian, alcohol might have been involved in some of the crashes.
