Sample Wisconsin School Bus Test Questions

Question 1

What basic procedure should a school bus driver follow at a required railroad crossing stop?

  1. A Stop, proceed and stop again
  2. B Stop, check the signals and turn on the radio
  3. C Slow, listen and continue
  4. D Stop, look and listen

Correct answer: D – Stop, look and listen

In Wisconsin, loaded and empty school buses must stop at railroad crossings unless the tracks are posted “exempt” or “abandoned.” At the crossing, the driver must look and listen carefully for an approaching train. Active signals do not replace the driver’s responsibility to make sure proceeding is safe.

Question 2

After stopping to unload students at school, how should the bus be secured?

  1. A Leave it in gear and release the service brake
  2. B Shift to Neutral and immediately lift your foot from the brake
  3. C Shift to Park but release every brake
  4. D Shift to Park or Neutral, apply the foot brake and set the parking brake

Correct answer: D – Shift to Park or Neutral, apply the foot brake and set the parking brake

The Wisconsin unloading procedure calls for a complete stop, shifting to Park or Neutral and applying the foot brake. The driver then secures the bus by turning off the ignition and engaging the parking brake. The key must also be removed if the driver leaves the driver’s compartment.

Question 3

What must happen before students approach a bus that has stopped to load them?

  1. A They may approach as soon as the amber lights turn off
  2. B The driver should wave them forward before checking traffic
  3. C They should begin boarding while the bus finishes stopping
  4. D The driver must make a final traffic check and then signal them to approach

Correct answer: D – The driver must make a final traffic check and then signal them to approach

Students should board only when the driver signals them. Before giving that signal, the driver must complete the safe stopping procedure and make a final check that traffic has stopped. The entrance door can then be fully opened and the students directed to approach in an orderly manner.

Question 4

Properly adjusted crossover mirrors should show the area extending from the front of the bus to the service door.

  1. A True
  2. B False

Correct answer: A – True

Crossover mirrors must provide a view of the front danger zone, both front tires where they touch the ground and the area extending to the service door. They work with the flat and convex mirrors to help the driver check for children or objects around the bus.

Question 5

What should students do when they must cross the roadway after leaving the school bus?

  1. A Run across as soon as they leave the bus
  2. B Stop where the driver can see them, wait for the signal and check traffic while crossing
  3. C Cross without looking if the bus has a crossing-control arm
  4. D Walk behind the bus and cross from there

Correct answer: B – Stop where the driver can see them, wait for the signal and check traffic while crossing

Students should move to a position in front of the bus where the driver can see them and stop at the roadway’s edge. They should cross only after receiving the driver’s signal. While crossing, they must look in both directions, make sure the roadway is clear and continue watching for traffic.

Question 6

How should you apply the brakes during normal braking in a school bus equipped with ABS?

  1. A Apply maximum force because the wheels cannot lock
  2. B Use the parking brake to increase braking force
  3. C Pump the brake pedal repeatedly
  4. D Use your normal braking technique and only the force needed

Correct answer: D – Use your normal braking technique and only the force needed

Brake as you normally would, using only enough force to stop safely and maintain control. ABS activates when a wheel would otherwise lock because of excessive braking. During emergency braking in an ABS-equipped bus, do not pump the brake pedal.
