A Merrick man has been accused of beating a West Sayville man following a road rage altercation that led to a car crash on the Southern State Parkway in West Babylon over the weekend.

New York State police said Rodney Selman, 42, got into a traffic dispute with the 49-year-old victim that resulted in one driver rear-ending the other while driving eastbound near exit 36 for Straight Path shortly before 9 p.m. Friday.

When both drivers pulled over, the feud escalated into a physical fight with the suspect throwing the victim to the ground, police said. The victim was taken to Good Samaritan Hospital in West Islip for treatment.

Selman was charged with assault. He will be arraigned at First District Court in Central Islip.
