A Bronx driver used his fist to settle a traffic dispute with an elderly man in a road rage incident that was caught on camera.

The suspect could be seen arguing with a 72-year-old as both drivers stood next to their vehicles in Morris Heights on April 24, according to police.

The pugnacious perp then cold-cocked the man in the head, video of the incident shows.

He fled the Jerome Avenue and Featherbed Lane scene and left the victim with a laceration, police said.

The injured driver was treated at St. Barnabas Hospital following the afternoon incident, according to the NYPD.

The incident remained under investigation Tuesday.
