Christopher Meli, 51, was upset with a temporary backup on Leonia Avenue as a man was teaching his girlfriend to parallel park on Monday, Sgt. Geoffrey Cole said.
Meli began honking his horn and exchanged words with the 29-year-old man before initially leaving, Cole said.
He then returned with a pocket knife and threatened him, the sergeant said.
Meli barricaded himself when police arrived but surrendered a short time later, Cole said.
No one was injured, he said.
Meli was processed at police headquarters and sent to the Bergen County Jail to await a first appearance in Central Judicial Processing Court.
He remained there on Tuesday, charged with aggravated assault, making terroristic threats, obstruction, hindering and weapons counts.
