We have new exclusive new details on a road rage incident that is going viral. Eyewitness News was the first to show you the video Saturday.
When David Dao started recording cell phone video, an argument was already underway at the intersection of FM 1960 and 290 Saturday around 11:30am. And, in less than three minutes, things quickly escalated.
On the video, you can see the truck's driver try to calm down the woman, who is his passenger. Then as the white car pulls up, the truck drives up suddenly:

The woman approaches the white car again and the passenger throws a drink at her. The truck's driver then kicks the car's grille, which sparks an all-out brawl in the middle of the roadway.
We spoke to the driver of the white car on the phone. He did not want to go on camera.
The man driving the car claims the blue truck was speeding and nearly hit his car. The drivers exchanged words. Then the man driving the car claims the truck driver cursed at him, and it grew more heated from there.
