School Bus Practice Question 8

SSchool Bus · Question 8

The stop arm is deployed when:

• AThe amber lights are on
• BThe bus is fully stopped and the red lights are flashing
• CThe driver leaves the bus
• DLoading is complete

Correct answer: B. The bus is fully stopped and the red lights are flashing

Why: Stop arm extends only with the red lights, after the bus is at a complete stop. It signals motorists to stop and not pass the bus.

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.
