Sample South Carolina School Bus Test Questions

Question 1

While students are boarding, you notice that an expected student is missing. What should you do?

  1. A Wait at the stop until the student arrives
  2. B Ask the other students where the student is
  3. C Leave immediately without checking
  4. D Finish the route before asking about the student

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

The driver should count the students at the stop and, when possible, know which students normally board there. If an expected student is missing, ask the other students where that student is. Continue monitoring the mirrors and make sure all boarding students are seated and facing forward before moving the bus.

Question 2

At a passive railroad crossing, who must make the final decision that the school bus can cross safely?

  1. A The school bus driver
  2. B The dispatcher
  3. C A student assistant
  4. D The driver of the vehicle behind the bus

Correct answer: A – The school bus driver

A passive crossing has no active traffic-control device to regulate traffic. The school bus driver must search for trains and determine whether sufficient clear space exists to cross safely. South Carolina law also requires the driver, after stopping, to ascertain that it is safe before crossing the tracks.

Question 3

A school bus may have a tail swing of up to:

  1. A One foot
  2. B Three feet
  3. C Five feet
  4. D Seven feet

Correct answer: B – Three feet

A school bus can have as much as three feet of tail swing. During a turn, the rear of the bus moves in the direction opposite the front of the bus. Check the mirrors before and throughout each turn to monitor this movement and maintain clearance from vehicles, pedestrians, and fixed objects.

Question 4

When unloading at school, the driver must remove the ignition key even when remaining in the driver’s compartment.

  1. A FALSE
  2. B TRUE

Correct answer: A – FALSE

When unloading students at school, the driver should secure the bus by turning off the ignition switch. The ignition key must be removed if the driver leaves the driver’s compartment. Because the statement requires key removal even when the driver remains in the compartment, it is false.

Question 5

Which three actions are essential before a school bus proceeds across railroad tracks?

  1. A Stop, accelerate, and shift
  2. B Slow, signal, and sound the horn
  3. C Stop, check the radio, and proceed
  4. D Stop, look, and listen

Correct answer: D – Stop, look, and listen

The bus must stop before the tracks, and the driver must look and listen for an approaching train. Radios and other noisy equipment should be turned off, passengers should be quiet, and the service door and driver’s window should be opened. Proceed only after checking the signals again and determining that every track is clear.

Question 6

What should a driver do after missing a student’s unloading stop?

  1. A Do not back up; follow the established local procedure
  2. B Reverse to the missed stop immediately
  3. C Unload the student at any convenient location
  4. D Have the student walk back from the next stop

Correct answer: A – Do not back up; follow the established local procedure

The South Carolina CDL manual specifically instructs drivers not to back up after missing a student’s unloading stop. The driver should follow the local procedure established for that situation. The student should not be discharged at an unapproved location merely because the scheduled stop was missed.
