MFSAB Bus (Multi-function School Activity Bus):
MFSAB Bus or multi-functional school activity bus is defined as a school bus that does not transport students to and from home or school bus stops. Technically, though, the MFSAB is a vehicle that must meet all of the requirements for a school bus, save traffic control devices. The only requirement that the MFSAB will not have is the flashing lights or stop arms used in pick-up and drop-off of students from a bus stop or home. An MFSAB is also called a shuttle bus.
