"She was going north on Route 21 around 10:30 [a.m.] when she lost control and the car went over the guardrail," one said. "It flipped three or four times and landed in the river."
A Belleville police officer arrived as the passerby jumped in.
He threw them a safety preserver ring and pulled both to shore, a local police officer said.
Dive teams from Lyndhurst, Wallington, North Arlington brought the vehicle to the North Arlington riverbank to be towed out.
The submerged car can be seen in this aerial shot:
