A minor accident in Houston this week turned into a shoot out between two men as they emerged from their vehicles and began firing their handguns moments later.
The road rage incident was captured by television station KTRK in Houston.
The station reported a woman was grazed by a bullet and received treatment at a hospital.
"We were trying to console her and let her known an ambulance was on the way and you could hear the sirens, and to just hold on," said Erica Simon, a reporter with KRTK, who was on the scene.
One of the gunmen was also wounded and taken to the hospital.
Motorists at the scene found themselves caught in traffic.
"He was just wielding the gun everywhere shooting bullets and I felt so helpless because I wanted to tell people to stop going near there," said Annie Ranck, who witnessed the shooting.
