In terms of dumb things you can do while driving, brake checking a truck hauling 50,000 lbs (22,679 kg) ranks right up there. Nevertheless, this Volkswagen Jetta driver decided to do just that.

This video, uploaded by the upset truck driver, shows the trucker being aggressively overtaken by a number of motorists as he attempts to change lanes to the left. After waiting almost 15 seconds with his turn signal on to make the move, the trucker shifts to his left and slots into traffic behind a minivan.

Seemingly out of nowhere and with the horn blaring, a fast-moving Jetta speeds past the trucker and aggressively cuts in front of him before slamming on the brakes.

Rather than briefly tapping the brake pedal to signal to the trucker that he was a little too close for comfort (a situation created by the VW driver, mind you), the motorist almost grinds to a halt, forcing the trucker to slam on his brakes to avoid a nasty collision.

Look, people often do stupid things when behind the wheel. We’re all guilty of it. However, getting angry at a truck driver and attempting a dangerous brake check is simply idiotic. If a collision were to have occurred, it doesn’t take a genius to realize that the Jetta would have come off second best.
