A 20-year-old woman was killed after a single-vehicle accident in Brooklyn, cops said.

The victim was the passenger in a 1994 Honda Civic when the driver, also 20, struck multiple parked cars at 3:50 a.m. Tuesday on St. John’s Place between Rogers and Nostrand avenues in Crown Heights, police said.

She was ejected from a rear window and pronounced dead at Kings County Hospital, authorities said. The driver is in stable condition at Methodist Hospital.

Police couldn’t immediately say if alcohol played a factor or if he simply lost control.

No charges were lodged and the investigation is ongoing.
