A 9-year-old girl was critically hurt when her allegedly boozed-up uncle got into a crash with another drunk driver in Brooklyn early Tuesday, according to cops and police sources. 

The girl’s uncle, Marcos Portorreal, 53, was driving a Ford Explorer south on Kings Highway and making a left turn onto East 92nd Street in East Flatbush around 1 a.m. when he collided with a Range Rover heading north on Kings Highway, according to authorities and the sources.

The girl, who was in her uncle’s car, was taken to the Kings County Hospital Center in critical condition, with a broken leg and brain injuries, authorities said. 

Three other passengers in the Ford — two 46-year-old women and one 28-year-old woman — each suffered minor injuries, cops said. 

Portorreal was arrested and charged with driving while intoxicated, police said. 

The driver of the Range Rover, 40-year-old Garth Morris, was hit with the same charge, cops said.
