N.J. Stat. § 39:4-90
The driver of a vehicle approaching an intersection shall yield the right of way to a vehicle which has entered the intersection. When 2 vehicles enter an intersection at the same time the driver of the vehicle on the left shall yield the right of way to the driver of the vehicle on the right.
The driver of a vehicle within an intersection intending to turn to the left shall yield to a vehicle approaching from the opposite direction which is within the intersection or so close thereto as to constitute an immediate hazard, but the driver having so yielded, and having given a signal when and as required by law, may make the left turn; and other vehicles approaching the intersection from the opposite direction shall yield to the driver making the left turn.
