A city Department of Correction bus jumped a curb and smashed head on into scaffolding in Brooklyn on Thursday night, injuring the two correction officers and both prisoners on board, police said.

The driver of the bus, a female correction officer, lost control and crashed on Johnson Street near Jay Street at about 5:10 p.m., according to cops and witnesses.

The scaffolding landed on the hood of the bus, which suffered a cracked windshield from the impact.

A window of a New York City College of Technology building was also damaged in the crash.

All four occupants sustained minor injuries, authorities said.

The correction officers were taken away on stretchers and transported to NewYork-Presbyterian Brooklyn Methodist Hospital, police and witnesses said.

The driver was wheeled away with a neck brace on, according to witnesses.

The prisoners at first refused medical attention, but were later taken to Brooklyn Hospital, police said.
