Sample Delaware School Bus Test Questions

Question 1

While students are boarding, you realize that one student expected at the stop is missing. What should you do?

  1. A Wait indefinitely for the student
  2. B Ask the other students where the missing student is
  3. C Immediately continue to the next stop without checking
  4. D Cancel the remainder of the route

Correct answer: B – Ask the other students where the missing student is

On a Delaware route, count the students waiting at the stop and make sure each one boards. If an expected student is missing, ask the other students where that student is. This helps the driver gather information while continuing to monitor the mirrors and loading area.

Question 2

A school-bus driver believes a scheduled stop should be moved. What is required before using the new location?

  1. A Verbal notice to the parents
  2. B Agreement from the students who use the stop
  3. C Written approval from the appropriate school district official
  4. D A note placed inside the bus

Correct answer: C – Written approval from the appropriate school district official

Delaware districts create school-bus routes and stops, and bus operators must follow those locations. A driver should not relocate a stop independently, even if another location appears more convenient. Written approval from the appropriate school district official must be obtained before the stop is changed.

Question 3

What is the main function of a school bus’s overhead inside rearview mirror?

  1. A Checking the driver’s appearance
  2. B Watching traffic directly behind the bus
  3. C Replacing the required post-trip inspection
  4. D Observing passenger activity inside the bus

Correct answer: D – Observing passenger activity inside the bus

The overhead inside mirror allows the driver to observe students and other passengers in the bus. It may provide limited visibility through certain rear emergency doors, but it does not adequately show traffic behind the bus. Exterior side mirrors must be used to monitor vehicles approaching from the rear.

Question 4

After boarding is complete on a Delaware route and every student is seated and accounted for, which pair of actions belongs in the departure sequence?

  1. A Close the door and turn off the alternating flashing red lights
  2. B Open the door and activate the hazard flashers
  3. C Keep the red lights operating while entering traffic
  4. D Move the bus before making the final mirror check

Correct answer: A – Close the door and turn off the alternating flashing red lights

Before leaving, close the door and turn off the alternating flashing red lights. The complete departure sequence also includes engaging the transmission, releasing the parking brake, signaling left, and checking every mirror again. Enter traffic only after students are accounted for and it is safe to proceed.

Question 5

What is the principal safety benefit of anti-lock brakes on a school bus?

  1. A They operate only after the driver activates a special switch
  2. B They help prevent wheel lockup during hard braking and help maintain control
  3. C They guarantee a shorter stopping distance on every surface
  4. D They require the driver to use a different normal-braking technique

Correct answer: B – They help prevent wheel lockup during hard braking and help maintain control

ABS detects impending wheel lockup and adjusts brake pressure to help the driver maintain control. It may or may not shorten the stopping distance, but it can help preserve steering ability and prevent skids caused by overbraking. During normal braking, use the same basic braking technique whether or not the bus has ABS.

Question 6

As a Delaware school-bus driver approaches a railroad-highway grade crossing, approximately how far before the crossing should the hazard lights be activated?

  1. A 200 feet
  2. B 300 feet
  3. C 400 feet
  4. D 600 feet

Correct answer: A – 200 feet

Activate the hazard lights approximately 200 feet before the railroad-highway grade crossing. This gives following drivers advance notice that the bus is slowing and preparing to stop. Continue scanning the surroundings and checking traffic behind the bus while approaching the crossing.
