A 47-year-old man was critical Sunday morning after being struck in a hit-and-run in Brooklyn, cops said.

The man was hit by a westbound black Nissan SUV around 3:40 a.m. at Conduit Boulevard and Crescent Street in Cypress Hills, according to the NYPD.

The SUV did not stop, cops said.

EMS rushed the 47-year-old to Brookdale Hospital, where he was in critical condition with head trauma Sunday morning, according to authorities.

“The car hit him and he landed by a tree across the street and the drivers passing stopped to try to help him,” said Anjum Joseph, 48, the manager of the nearby Bolla Market who told The Post he saw a video of the accident.
