Sample South Carolina School Bus Test Questions

Question 1

In South Carolina, how far from the nearest rail must a school bus stop before crossing railroad tracks?

  1. A Between 10 and 40 feet
  2. B Between 15 and 30 feet
  3. C Between 20 and 50 feet
  4. D Between 15 and 50 feet

Correct answer: D – Between 15 and 50 feet

South Carolina law requires a school bus to make a full stop not less than 15 feet and not more than 50 feet from the nearest rail. The CDL manual directs the driver to stop within that range where the tracks are most visible. After stopping, the driver must determine that crossing is safe before proceeding.

Question 2

A school bus driver must wear the installed driver’s safety belt whenever operating the bus.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

A driver may not operate a commercial motor vehicle equipped with a driver’s seat belt unless properly restrained by that belt. The rule applies while operating the school bus, regardless of the trip’s length. Wearing the belt also helps keep the driver positioned behind the wheel and able to maintain control during sudden maneuvers or a crash.

Question 3

Which condition is specifically identified as a concern when deciding whether to evacuate a school bus?

  1. A The smell of raw or leaking fuel
  2. B Students having a loud conversation
  3. C A routine flat tire in a safe parking area
  4. D A student missing an unloading stop

Correct answer: A – The smell of raw or leaking fuel

The South Carolina CDL manual identifies the smell of raw or leaking fuel as a condition to consider when deciding whether evacuation is needed. The driver must recognize the hazard and make a timely decision. A fire or threat of fire requires evacuation, while other conditions must be evaluated based on the danger of remaining aboard versus leaving the bus.

Question 4

When outside convex mirrors are properly adjusted, which tire area should be visible?

  1. A The tops of the front tires
  2. B Only the rearmost portion of the rear tires
  3. C The front of the rear tires touching the ground
  4. D Both front tires through the windshield

Correct answer: C – The front of the rear tires touching the ground

Properly adjusted outside convex mirrors should show the entire side of the bus up to the mirror mounts, the front of the rear tires touching the ground, and at least one traffic lane on each side. These mirrors provide a wide-angle view, but they distort the apparent size and distance of people and objects.

Question 5

Why must a school bus driver use extra caution at a passive railroad crossing?

  1. A Other vehicles are permitted to pass on the tracks
  2. B The crossing’s bells can hide the sound of a train
  3. C No active traffic-control device regulates the crossing
  4. D Trains are required to travel faster there

Correct answer: C – No active traffic-control device regulates the crossing

A passive crossing has no active traffic-control device. The driver must recognize the crossing from signs and markings, search the tracks for trains, and determine whether enough clear space exists to cross safely. Because no automatic device controls traffic, the decision to proceed remains with the driver.

Question 6

After choosing the appropriate type of school bus evacuation, what should the driver do next?

  1. A Secure the bus
  2. B Open every window
  3. C Send students for help before stopping the engine
  4. D Move the bus regardless of its condition

Correct answer: A – Secure the bus

After selecting the evacuation method, the South Carolina CDL manual directs the driver to secure the bus. Place the transmission in Park, or Neutral if there is no Park position, set the parking brake, shut off the engine, remove the key, and activate the hazard-warning lights. If time permits, notify dispatch after the bus is secured.
