Blue Bird BB Conventional (2016, 2017, 2018, 2020), IC Bus PB105 (2012).

Reported by the companySep 30, 2026: 50 motorcoaches and 54 school buses of 9 to 15 seats. 70 drivers, all with a commercial license.

Why the numbers differ: only vehicles that met an inspector or a crash report appear on the records. Maryland doesn’t inspect every bus each year the way California does.
