This bill amends current New Jersey law to require the issuance of a single license plate for each automobile and motorcycle registered in the state, which must be displayed on the rear of the vehicle. The previous requirement for two license plates has been removed, and the bill specifies that individuals who were issued two license plates prior to the bill's effective date may return one plate to the New Jersey Motor Vehicle Commission. Additionally, the bill allows for the license plate to be displayed at a height greater than 48 inches for certain commercial vehicles and sanitation vehicles.

The bill also includes provisions regarding the visibility and maintenance of the license plate, prohibiting any obscuring of the plate's markings. It establishes penalties for displaying fictitious numbers and outlines fines for other violations related to license plate regulations. The act is set to take effect on the first day of the fourth month following its enactment, with provisions for anticipatory actions by the Chief Administrator of the New Jersey Motor Vehicle Commission to ensure timely implementation.
