A few years ago, a video appeared on the Internet showing the irrational behavior of a semi-trailer driver.

He overtook a truck on the highway, braked perfectly in front, and finally learned a better lesson.

The video, uploaded to YouTube two years ago, has already become a hit, with nearly 4 million views to date, and many netizens commending the truck driver’s calmness.

When he overtook the truck in front of him on the freeway, he swerved back into his lane, obviously distracted by the waiting pickup driver. He overtook the author of the video clip, and then, for no reason, he braked in front of the truck.

In the end, the reckless driver learned a big lesson, because his behavior was noticed by the police on the road. They stopped the attacker, and then a truck driver stopped in front of them and told the police what had happened. Lesson learned?
