Traffic was backed up on the 101 Freeway at around 9:30 a.m., the witness said, when two men in cars in front of him began yelling at each other as they “were jockeying for position.”

One of the men leaned out his window and punched the other driver’s car door, and at that point they both got out of their cars and begin to fight, according to the witness.

The video shows one of the men almost falling into moving traffic after getting punched.
