A dumbass driver’s impatience caused a horrific crash … and the video is hair-raising.

The video — taken on I-64 in Virginia  … shows one vehicle tailgating another … aggressively trying to get around the other car.

The driver makes the move on the left shoulder … bouncing along the grassy side of the interstate, until its tires spin out, and the small SUV begins tumbling.

Good news here … the person who posted the video says the driver was up and talking before paramedics arrived … and shared a pic of the woman sitting up on a stretcher.

It’s not clear why this person decided to pass the other vehicle … but, it looks like they dodged what could’ve been a deadly situation.
