There are many reasons why you shouldn’t cut off a semi truck. Anyone who’s gotten behind the wheel of a big rig for even a day knows why.

For everyone else, this video should help.

Here’s what happened when a red Saturn thought it would be okay to pull in front of a semi on the left in order to pass another one on the right. The trucker who posted the video on LiveLeak added the following caption:

The girl driving the impacted car was transported to the hospital with minor injuries after she made a VERY poor decision. An 80,000 lb rig vs. your 2,000 – 4,000 lb car will result in at least your car being torn up, at worst, we are pulling your corpse out from the wreckage. Give us room to work, stay away from our rear and sides and front.

As the driver bluntly, and accurately, put it, “Show us some respect, because your life, and the lives of your loved ones depend on it!”
