You might want to add a bullet proof vest to your list of PPE as you leave your house to drive to work or the store, ‘cause it's becoming a war zone out there!

Watch as a FL driver opens fire WHILE DRIVING 100 MPH on the highway, shooting through his own windshield at another driver.

Marco Mazzetta claims another driver, in a Nissan 370z, had been driving aggressively, and had even bumped his truck before passing him, then slowing down, and flashing a firearm at him through an open window.

Fearful for his own life, Mazzetta said he reacted by pulling his own gun and opening fire, right through his own windshield.

"I'm not a fan of guns; I'm a fan of not getting shot."

The whole incident was caught on Mazzetta's dash cam as a stunned male in the passenger seat fearfully looks on.

"I know this video doesn't capture my smartest moments," he told a local reporter.
