A suspected drunk driver plowed into four people — including a child — during a Halloween event outside a Brooklyn NYPD precinct, cops and sources said.

The 56-year-old motorist lost control of his black sedan around 4 p.m. and mounted the curb — hitting the victims at the “Trunk or Treat” event outside the 83rd Precinct stationhouse on Knickerbocker Avenue near Bleecker Street in Bushwick, police said.

He also struck a private ambulance stationed outside for the event, authorities said.

Three adults and one child were taken to Wyckoff Heights Medical Center, where they were listed in stable condition, cops said.

A few others were checked out at the scene by EMS, the FDNY said.

The driver was taken into police custody, where he is undergoing an alcohol breathalyzer test, sources said.

There was no indication that he intentionally targeted the police officers or children, and the incident was not terror-related, according to the sources.
