P.S.C. truck
Public Service Commission generally regulates Commercial and For-Hire transportation, among many other things. As far as license plates are concerned, PSC plates were generally the precursor to Apportioned plates, though there are some differences and there was an overlap in issuance 1986-1992. In most cases PSC plates were used in conjunction with other plates, usually a weight truck plate.
Today, a system exists of a sticker applied to the side of a tractor-trailer, or an internal code on the registration of For Hire vehicles, such as Charter Limousines, Taxis and Buses.
