New Jersey Statutes Title 39. Motor Vehicles and Traffic Regulation 39 § 3-27.115

a. Upon the application of a former member of the New Jersey State Legislature, the Director of the Division of Motor Vehicles shall issue special registration plates for a motor vehicle owned or leased by the former member. The plates shall identify the holder as a “Senate-Former Member” or “General Assembly-Former Member”; provided however, if the former member served in both the General Assembly and the Senate, the former member shall receive plates identifying him as a former member of the Senate. The plates also shall contain the Shield of the State of New Jersey, in addition to the registration number and other markings or identification otherwise prescribed by law. The identifying characters displayed on the license plate shall be in a form as to adapt to the size of the license plate. The director shall design the special plates, subject to approval by the President of the Senate and Speaker of the General Assembly.

b. In addition to the fees otherwise prescribed by law for the registration of motor vehicles, an application for these special plates shall be accompanied by a fee of $50, which shall be retained by the Division of Motor Vehicles, to defray the cost of producing and distributing the plates. The application also shall be accompanied by proof, in a form specified by the director, that the applicant served as a member of the New Jersey General Assembly or State Senate.
