Hasbrouck Heights firefighters got the car and him out from under it, Colaneri said.
The victim was taken to Hackensack University Medical Center, where the extent of his injuries was to be determined, the lieutenant said.
His mother also was taken to HUMC with minor injuries after she was grazed, he said.
