New Jersey Statutes Title 39. Motor Vehicles and Traffic Regulation 39 § 4-86

The driver of a vehicle shall not drive to the left side of the center line of a highway in overtaking and passing another vehicle proceeding in the same direction unless the left side is clearly visible and free of oncoming traffic for a sufficient distance ahead to permit the overtaking and passing to be made in safety.

The driver of a vehicle shall not drive to the left of the center of a highway in order to overtake and pass another vehicle proceeding in the same direction upon the crest of a grade or upon a curve in the highway where the driver's view along the highway is obstructed within a distance of five hundred feet.

Except when otherwise directed by a duly constituted traffic or police officer or when the lane in which he is operating is obstructed and impassable, the driver of a vehicle shall not cross an appropriately marked “No Passing” line in a “No Passing” zone duly established pursuant to a duly promulgated regulation of the State Highway Commissioner or an ordinance or resolution duly adopted by a municipal governing body or a board of chosen freeholders, whichever has jurisdiction over the highway.
