Warning: video contains profanity and violence.
A confrontation between two drivers on a busy Austin street quickly escalated into a battle with weapons.
An onlooker captured the tense standoff on his cell phone Monday, which starts with a man marching over to a pickup truck and striking its door with a baseball bat.
The driver in that truck immediately jumps out, then runs back into his truck to put it in park. He reaches into the car and pulls out a wooden rod.
The men then begin to duel, hitting each other back and forth while other cars drive ahead.
The people shooting the video can be heard laughing at the men.
The incident was reported to Austin Police, who are cautioning motorists to keep calm on the road and avoid provoking other drivers.
