School Bus Practice Question 21

SSchool Bus · Question 21

A bus driver who notices a defect during pre-trip should:

• ADrive anyway
• BRepair if safe and authorized, otherwise report and not drive until repaired
• CWait until the next driver
• DDrive only short distances

Correct answer: B. Repair if safe and authorized, otherwise report and not drive until repaired

Why: Defects must be addressed before driving. Driving with known defects on a bus carrying students is a serious violation and risk.

How this question fits the School Bus test

Most fatal school bus incidents happen outside the bus, in the danger zones around it. This endorsement exists to make sure every driver can predict the behavior of children entering and exiting the loading zone.

Study technique for this topic

Know the dimensions of the front, side, and rear danger zones, the proper eight-light activation sequence, and the emergency evacuation procedure including front-door, rear-door, and split evacuations.
