A Virginia driver, a Maryland driver, two guns, and a knife sounds like a setup for a joke. But as the Post reports, it was the exact combination of things that came together for an insane road rage incident in D.C. last weekend:

The man behind the wheel of the yellow Scion TC said the woman driving the blue Toyota RAV4 wouldn’t let him into the right lane to exit near East Capitol Street. She waved a knife through her car window, the man told D.C. police.

He brandished a gun, the woman told police in response, explaining that she could see the weapon in her rearview mirror.

The female driver stopped, forcing the man to slam on his brakes on busy Interstate 295, police said. Both got out — but without their weapons. An off-duty Prince George’s County police officer who intervened said in a report that he saw the woman punch the man in the head before intervening and separating them.

Authorities said the man had a black .380 Smith & Wesson on the driver’s side floorboard of his vehicle and a black Glock 29 in the center console. Police said the Glock had an extended clip, and both were loaded.

Both were charged, the Virginia man for illegally possessing a gun in D.C. and the Maryland woman for assault and carrying a knife.
