C. Only the area directly behind the rear bumper
D. About 25 feet on each side and 50 feet behind the bus
Source: FMCSA CDL Manual §10.1.1

D. The state police department
Source: FMCSA CDL Manual §10.2.1

C. Because the bus mirrors cannot be adjusted to cover the left side
D. Because state law forbids students from standing on the left side
Source: FMCSA CDL Manual §10.1.1
