About 200 feet in advance (more in 50+ mph zones)
At the stop
After unloading
Only at night

10 feet in front, on each side, and behind the bus, plus any area required for the bus to maneuver
Only behind the bus
Only in front

At the school

Correct. The majority of student deaths involving school buses occur outside the bus, often in the danger zone right after unloading.

Question 12 of 20

When backing a school bus, you should:

Avoid backing whenever possible; if you must back, use a helper, sound the horn, never back across a roadway, never back with students aboard if avoidable
Back at full speed
Back with no warning
Back across roadways

After unloading at the end of the route, the driver must:

Walk through the bus to check for sleeping or hiding students, lost items, damage
Skip the walkthrough

Student management is important because:

Distracted driving by managing students causes crashes

You see a student running back toward the bus after being unloaded. You should:

Wait until the student is clear, account for them, before moving
Continue moving
Honk and accelerate

Securing the bus at the end of the day:

Park in designated area, set parking brake, turn off engine and lights, secure all doors
Leave the engine running
