An off-duty FDNY firefighter was arrested on charges of driving drunk and leaving the scene after crashing a car in the Bronx, police said.

Jose Valdez, 37, was busted at around 9:45 p.m. Friday in the 45th Precinct, which serves a portion of the northeastern section of the borough, authorities said.

Cops spotted Valdez, who was behind the wheel of a gray 2018 Jeep, rear-end another vehicle and then drive off, the NYPD said. Following a car stop, he was placed under arrest.

Valdez was charged with driving while intoxicated, leaving a scene with property damage as a driver, driving while impaired by alcohol, and refusing to take a breath test, police said.

The parked car was unoccupied at the time of the crash, police said. No one was reported injured.
