Sample Washington School Bus Test Questions

Question 1

Children in a school bus danger zone are at risk only from being struck by their own bus.

  1. A FALSE
  2. B TRUE

Correct answer: A – FALSE

Children in a danger zone may be struck by their own school bus or by another vehicle. The area to the left of the bus is always considered dangerous because passing vehicles may enter it. Drivers must monitor the entire area around the bus rather than watching only the bus's immediate path.

Source: Washington State Commercial Driver Guide — § 10.1.1, “Danger Zones”.

Question 2

Under Washington rules, which vehicle requires a CDL with the proper school bus endorsement regardless of its seating capacity?

  1. A A family van carrying fewer than six people
  2. B A passenger car used by a school employee
  3. C A public school bus
  4. D A privately used recreational vehicle

Correct answer: C – A public school bus

State regulation requires every public school bus, regardless of capacity, to be operated by a driver with a CDL and the proper classification and endorsements. The S endorsement authorizes operation of school buses. The 16-person threshold applies to the general passenger-vehicle category and does not eliminate the separate public-school-bus requirement.

Question 3

Which situation requires a school bus driver to evacuate the students?

  1. A The ABS malfunction lamp remains on
  2. B The bus stalls on a railroad-highway crossing, although no train is visible
  3. C The bus is safely parked on a highway shoulder and the interior is warm
  4. D The dispatcher asks the driver to wait for assistance in a safe location

Correct answer: B – The bus stalls on a railroad-highway crossing, although no train is visible

A school bus stalled on or adjacent to a railroad-highway crossing must be evacuated. This requirement does not depend on whether a train is currently visible. Students should be moved away from the tracks and toward an approaching train's direction, because collision debris travels in the train's direction of movement.

Source: Washington State Commercial Driver Guide — § 10.3.1, “Planning for Emergencies”—“Mandatory Evacuations”; § 10.4.4, “Special Situations”—“Bus Stalls or Trapped on Tracks”.

Question 4

How should a school bus driver use the crossover, convex, and flat mirrors when checking the danger zones?

  1. A Look into every mirror simultaneously at four-second intervals
  2. B Check only the mirrors showing traffic behind the bus
  3. C Check the interior mirror before looking at any outside mirror
  4. D View the mirrors in a logical sequence to locate any child or object

Correct answer: D – View the mirrors in a logical sequence to locate any child or object

The crossover, convex, and flat mirrors should be checked in a logical sequence. This systematic scan helps the driver verify that no child or object is in a danger zone before moving the bus. Mirror adjustment and proper use are essential because no single mirror shows every area around the vehicle.

Source: Washington State Commercial Driver Guide — § 10.1.5, “Outside Left and Right Side Crossover Mirrors”.

Question 5

What should students do before crossing the roadway after leaving a school bus?

  1. A Run across immediately after the driver signals
  2. B Stop at the roadway edge, check for traffic, and wait for the driver's signal
  3. C Cross without stopping whenever a crossing arm is extended
  4. D Walk behind the bus and cross from there

Correct answer: B – Stop at the roadway edge, check for traffic, and wait for the driver's signal

The Washington guide instructs students to stop at the roadway edge, look in all directions, confirm the bus's red lights are still flashing, and wait for the driver's signal. After receiving the signal, they must remain visible in front of the bus and continue checking traffic as they cross. A crossing arm does not eliminate these precautions.

Question 6

During a school bus inspection, what must you verify about the passenger entry door?

  1. A It operates smoothly, regardless of how it closes
  2. B It closes securely only from a remote control
  3. C It closes securely from outside the bus
  4. D It is undamaged, operates smoothly, and closes securely from inside

Correct answer: D – It is undamaged, operates smoothly, and closes securely from inside

Washington’s supplemental CDL guide requires inspection of the passenger entry door for damage, smooth operation, and secure closure from inside the bus. The door is used for normal passenger entry and exit, so its condition and operation are safety-critical. The inspection also includes the handrails, entry steps, and any passenger lift.
