The incident took place just after 4 p.m. at the intersection of N. Highland Street and Clarendon Blvd, near the Clarendon Metro station.
It all started when one driver reportedly cut off another. That led to a dispute in which one of the parties involved got out of his or her vehicle. It was at that point that a man in the other vehicle flashed a gun, Arlington County Police spokeswoman Ashley Savage said Thursday.
The man drove off and no one was injured. A pedestrian was caught in the middle of the dispute and served as a witness for police, Savage said. There was also a cell phone video and surveillance video of the incident.
The suspect in the case later voluntarily came to the police station and was issued a court summons, Savage said. His court date is set for March 10.
