This bill amends New Jersey's current vehicle registration law to require the issuance of a single license plate for each automobile and motorcycle, which must be displayed on the rear of the vehicle. The existing requirement for two license plates is removed, and the language specifying the display of an identification mark is replaced with the requirement for a single license plate. Additionally, the bill allows for the display of the license plate at a height greater than 48 inches for certain commercial vehicles and clarifies that motorcycles must also display a single license plate on the rear.

Furthermore, the bill provides a provision for individuals who were previously issued two license plates, allowing them to return one plate to the New Jersey Motor Vehicle Commission and comply with the new single plate requirement. The act is set to take effect on the first day of the fourth month following its enactment, although the Chief Administrator of the New Jersey Motor Vehicle Commission is authorized to take necessary actions in advance for timely implementation.
