Insert Bus (or Gross Weight Bus, or "regular" Bus) plates are issued chiefly to chartered coaches, and are an interesting hybrid of designs. They display the weight codes and insert stickers of Insert Truck plates; yet often featured colors and replacement cycles more comparable to those of passenger plates.

This 1928 "City Bus" plate appeared on eBay in March 2007. Although it's without precedent, I assume it was a precursor of the BX Bus type:
BX Bus plates are intended for privately-operated urban mass transit vehicles. They carry a constant December expiration.

School Bus plates have gone through numerous formats and incarnations over the years. Early plates closely followed the conventions of Insert Truck plates; complete with weight codes and provision for a tab. A constant "SB" prefix was implemented from 1957 to 1972. Many School Bus plates carry an expiration month of June, coinciding with the end of the school year; though 1962-75 and 1988-98 issues expired in December. On-plate inspection stickers were introduced in the 1970s.
In late 2004, the previous Insert Bus, BX Bus, and School Bus types began to be combined into a consolidated "Bus" class. Plates issued to school buses may continue to be identified, however, by their inspection stickers and five-year June expirations.

Special plates for use on academic driver education program vehicles were introduced in 1975. The original black-on-red issue was evidently validated until 1988; afterwards, several series of plates were introduced adhering to the colors and replacement cycles of School Bus plates. Issuance of Driver Education plates was discontinued after 2004; however, some earlier plates remain in use.
