Members of the Paramus Volunteer Rescue Squad extricated the 27-year-old woman and 14-year-old boy after the crash closed the northbound highway around 1:45 p.m.
Both were taken to Hackensack University Medical Center with injuries that weren't considered life-threatening, Paramus Deputy Police Chief Robert Guidetti said.
It began when a Hyundai Sonata rear-ended the victims’ Nissan Sentra in the right lane of the highway just north of Midland Avenue, Guidetti said.
The force of the impact pushed the Sentra into a Ford Ranger pickup truck and then into the center lane, where it was struck and spun around by the Freightliner, the deputy chief said.
Police gave the 26-year-old Old Bridge driver of the Sonata a summons for careless driving, Guidetti said.
