Driver Stabs Another Motorist As Road Rage Incident Escalates, Wild Video

This might be the road rage to end all road rages — a driver going way beyond yelling and flipping off someone, and instead, resorting to stabbing another motorist on the roads of L.A.

Check out this wild confrontation — a driver, accompanied by a woman, exits his white SUV, whips out a knife and charges at the driver of a silver SUV in the middle of the road, stabbing him several times in the arm on Saturday afternoon in Ontario.

Things had already hit a boiling point leading up to the stabbing — with cops later confirming the whole thing started with one driver cutting off the other.

Various surveillance videos from local businesses show the silver SUV driver speeding into a parking lot, pulling up next to the white SUV, getting out, attempting to punch the other driver and then quickly fleeing.
