Question 1

At a railroad-highway grade crossing, what must a school bus driver do before proceeding across the tracks?

Accepted Answer

Stop 15 to 50 feet before the tracks, open the door, and listen for approaching trains

Answer

Federal regulations require school bus drivers to stop between 15 and 50 feet from railroad tracks, open the service door, and listen for trains before crossing — regardless of whether signals are active.

Question 2

Under which condition should a school bus driver immediately evacuate students from the bus?

Accepted Answer

When there is a fire or imminent danger of fire on the bus

Answer

A fire or risk of fire is a life-threatening emergency requiring immediate evacuation. Most other situations allow the driver to use judgment, but fire leaves no time to wait.

Question 3

Before crossing the road in front of a stopped school bus, students must walk at least how far ahead of the front bumper?

Accepted Answer

10 feet

Answer

Students must walk at least 10 feet in front of the bus so the driver can clearly see them over the hood before they begin crossing. Crossing closer than 10 feet puts students in the driver's blind zone.

Question 4

After completing the final run of the day, what must a school bus driver do before leaving the vehicle?

Accepted Answer

Check tire pressure and fluid levels

Answer

Drivers are required to walk the full length of the bus and check every seat — including under seats — to confirm no child remains on board. Students falling asleep or hiding can easily be missed otherwise.

Question 5

What is the purpose of the crossing control arm (pupil safety arm) found on the front of a school bus?

Accepted Answer

To prevent students from walking directly in front of the bus and into the blind zone

Answer

The crossing control arm swings out from the front bumper when the door opens, physically blocking students from walking too close to the bus and into the area directly in front of the hood where the driver cannot see them.
