A child is close to the front bumper below the driver’s direct view. Which school-bus mirrors are specifically intended to help check this danger zone?
Correct answer: The correctly adjusted front crossover mirrors.
Crossover mirrors show areas immediately in front of the bus and near the front wheels and service door. Use all mirrors in a systematic check; no single mirror covers every danger zone.

You counted a child at the stop, but cannot account for that child after the others board. What should happen before the bus moves?
Correct answer: Secure the bus, take the key, and check around and underneath it.
The driver must account for children before departure. If a child outside cannot be located, secure the vehicle and inspect the surrounding danger zones.

The final school-bus stop is complete and the bus sounds empty. What check should still be made at the end of the route?
Correct answer: Walk through and around the bus, checking especially for sleeping students and other problems.
A physical post-trip inspection can find sleeping students, belongings, damage, and equipment problems that a quick mirror glance misses.

After stopping a school bus at a railroad crossing, how can you improve the check for an approaching train?
Correct answer: Silence passengers and noisy equipment, open the service door and driver’s window, and look and listen.
The manual recommends reducing noise and opening the service door and driver's window to look and listen. Follow applicable state and local school-bus procedures as well; inactive warning lights do not prove the tracks are clear.

A school bus stalls on the tracks and a train is approaching. What direction should evacuated students move?
Correct answer: Away from the tracks and toward the approaching train, at an angle away from the bus.
Get everyone out and clear immediately. Moving away from the tracks toward the approaching train helps avoid the likely path of debris if the train hits the bus.

While children are unloading, two students inside begin arguing. What should remain your immediate focus?
Correct answer: The children outside and the unloading danger zones; address the behavior once they are safe.
Loading and unloading require the driver’s full outside attention. If needed, stop and secure the bus at a safe place to deal with a behavior problem after the unloading students are safe.

At an approved drop-off maneuver, backing is unavoidable and no safer option exists. Should students get off before or after the bus backs?
Correct answer: After backing, so students are not outside the bus during the maneuver.
Avoid backing wherever possible. If it is unavoidable, follow the lookout and inspection procedures and never back while students are outside; at a drop-off, back before unloading.

A school bus is parked close to a roadside object. As the driver steers away, why must the rear overhang be watched in the mirrors?
Correct answer: The tail can swing toward nearby objects on the side opposite the turn.
A bus’s rear overhang can swing outward as it turns. Check mirrors before and during the turn to protect the clearance beside the rear of the bus.

Strong gusts are pushing a school bus sideways. What is the manual’s recommended response?
Correct answer: Hold the wheel firmly, reduce speed, and stop safely off the roadway if necessary while coordinating with dispatch.
The broad side of a bus can catch strong winds. Anticipate gusts, slow down, and wait safely if conditions cannot be managed.
