An off-duty NYPD cop was arrested for drunken driving early Sunday after smashing his car into two vehicles in Queens, police sources said.

Officer George Kaewussdangkul, 26, crashed at the intersection of 41st Avenue and 114th Street in Corona around 12:06 a.m., cops said.

Responding officers said he smelled of alcohol but refused to take a Breathalyzer test, according to police sources.

Kaewussdangkul — a Bronx patrolman — was charged with driving while intoxicated and refusal to take a breath test, cops said. No injuries were reported.
