This is the shocking moment two drivers became involved in a dangerous road rage incident in the US state of Arizona last month.

Footage filmed in Phoenix on January 3 shows two men arguing at a set of lights.

One of the drivers in a dark blue sedan then deliberately rams the other man's car while he is outside the vehicle.

In retaliation, the man screams obscenities and begins to bang on the window of the driver who has just rammed his car.

Incredibly, the driver then drives directly at his foe but he leaps onto the hood and then stamps on the windshield.

As the lights change, the driver of the dark blue sedan then turns right sharply and runs over the other man sending him crashing onto the tarmac.

Fortunately, he can be seen getting to his feet a few moments later.

Shocked onlooker, Edward Zaragoza, said: ‘I was surprised when the man drove the car fast to deliberately slam into another vehicle. I wanted to go and help but the trouble all happened so fast.’
