Alecia S. Jones and Tyson S. Stamper, both 22, are charged with two counts of aggravated assault on a law enforcement officer, as well as resisting arrest and possession of marijuana.
Stamper, who has a criminal history, was wanted on outstanding warrants out of Elizabeth and Clark, records show.
The couple had been pulled over around 9:50 a.m. Saturday when they attacked the officer, NJSP Trooper Charles Marchan said.
Passing off-duty police officers and good Samaritans stopped to help the trooper subdue the couple.
They were arrested and the trooper was taken to a local hospital with injuries that Marchan said weren't life-threatening.
Stamper was treated for a facial injury sustained in the assault, responders said.
