Did you know? The way school districts number their buses varies greatly. Sometimes the numbers aren't just to differentiate one bus from another, but are a reference to something specific, like that bus's capacity, for example.
Durand school buses whose numbers are hyphenated, are done so to denote the year the bus was put into service. The number before the hyphen is the year the bus was purchased by the district.
Durand began using hyphenated numbers in the early 1980s but stopped again in the mid-2000s.
