This dash-cam footage is from a fully loaded semi, driving southbound on highway 41 near Little Chute, Wisconsin. As it is a very heavy vehicle, smart driver’s notice his slow speed and pass it around, using turn signals on and everything. As the truck goes through an overpass bridge, two black SUVs pass the heavy vehicle in the left lane.

Now, we all know what the left lane serves for. If you come across a slow-moving vehicle in front of you, use the left lane to pass it around and continue on your journey driving at the maximum speed allowed. The road in front of the semi, however, seems to be full of slower vehicles, so the first SUV probably wanted to pass them all before switching lanes, but the second SUV seems to have wanted to speed things up a bit. So they did what every respectable driver on this planet hates the most - they tailgated the car in front of them.

No one wants when people “breathe down their necks", or in this case, rear bumpers. That second SUV came pretty close to the one in front, so they got what they asked for. The first SUV slams on the breaks, causing the tailgater to lose control of their car in the middle of a highway and drive through the central barrier.

The rules on the road are there for all of us. We don’t think break-checking someone is a good idea, but the driver of a SUV with plates that say “PRINSES" sure got what she asked for.

While on the subject of terrible drivers that want to bypass the rules of traffic and semis, we just have to tell you what happens when you try the opposite of “PRINSES” here. We hope we don’t have to tell you how big semis can be. Given they have to haul enormous amount of freight, semis have moving power that can be difficult to stop at a moment's notice, so you would be smart to steer clear of their path if you find yourself near them on the freeway.

This driver, however, was "fortunate" enough to have the finger shown to him by the driver of that van, just before he tries to brake check the semi. If you ignore the rudeness, all you are left to judge upon is the guy's reasoning. What was he thinking? The finger was retrieved just before the semi's momentum nudged the driver into some sense and he slammed the gas pedal! Thank goodness for that dash cam.

This other driver had it much worse and that was purely out of negligence. A semi driver had the most unfortunate thing happen to them on the highway some 2 miles outside Lewisville. They are trying to over take a caravan in the middle lane, but a silver sedan from the far right lane tries to move to the far left lane on the highway, right in front of the heavy vehicle, cutting him off! The result is not at all pleasing.

This here is natural selection at it's finest!
