A reader recently sent us this dash cam clip, showing an impatient car driver putting her life at risk because she was upset about getting stuck behind his rig.

The video was uploaded by truck driver Brian Robertson, who wrote the following description:

This is a clear example of an aggressive driver. If I had been looking in my driver side mirror when she cut me off I would run over her. She really needs some anger management classes!

In the clip, Robertson moves to the left lane in order to pass another semi truck. After he completes the pass, a Toyota driver dangerously zooms in front of his rig and smashes her brakes in order to vent her frustrations. Had he not been paying close attention, the little Toyota would have been turned into scrap metal.

Most truckers experience these kind of incidents on a regular basis. It makes you wonder if people who perform these maneuvers are flat out stupid or just have a death wish. Perhaps it’s both.
