Sample South Carolina Passenger Test Questions

Question 1

When must a commercial bus driver use the installed driver’s seat belt?

  1. A Only on interstate highways
  2. B Whenever operating the bus
  3. C Only when passengers are aboard
  4. D Only in heavy traffic

Correct answer: B – Whenever operating the bus

Federal motor carrier rules prohibit operating a commercial motor vehicle with an installed driver’s seat belt unless the driver is properly restrained. The requirement applies whenever the driver operates the bus, not merely on highways or in heavy traffic. The South Carolina CDL manual also instructs bus drivers to use the seat belt at all times for safety.

Question 2

When should you sign the previous driver’s inspection report?

  1. A As soon as you enter the bus
  2. B Only when the previous driver is present
  3. C Whenever a mechanic asks you to sign
  4. D After reviewing it and confirming that the required repair certification is present

Correct answer: D – After reviewing it and confirming that the required repair certification is present

Federal inspection rules require a driver to review the last applicable vehicle inspection report before driving. The carrier must certify listed defects as repaired or as not requiring repair, and the driver signs after reviewing the report and acknowledging the required certification. A mechanic’s request or the previous driver’s presence does not replace that review.

Question 3

What indicates that a bus is traveling too fast through a banked curve?

  1. A The bus leans toward the outside of the curve
  2. B The bus remains level
  3. C The bus leans toward the inside of the curve
  4. D The engine speed decreases

Correct answer: A – The bus leans toward the outside of the curve

The South Carolina CDL manual identifies outward leaning on a banked curve as a sign that the bus is traveling too fast. Excessive curve speed can contribute to a rollover when traction is good or a slide when traction is poor. Drivers should reduce speed before entering the curve.

Question 4

Which type of tire is prohibited on the front wheels of a bus?

  1. A A regrooved, recapped, or retreaded tire
  2. B A radial tire with adequate tread
  3. C A properly inflated all-season tire
  4. D A tire meeting the required load rating

Correct answer: A – A regrooved, recapped, or retreaded tire

Federal motor carrier rules prohibit operating a bus with regrooved, recapped, or retreaded tires on its front wheels. The restriction is categorical and applies even if the tire otherwise appears serviceable. Front-wheel tires must also meet the applicable condition and minimum tread-depth requirements.

Question 5

On a dry road at 45 mph, what minimum following interval should a 30-foot bus maintain?

  1. A 3 seconds
  2. B 4 seconds
  3. C 5 seconds
  4. D 6 seconds

Correct answer: B – 4 seconds

The South Carolina CDL manual’s following-distance guideline allows one second for each 10 feet of vehicle length at speeds below 40 mph. A 30-foot bus starts with three seconds. Because the bus is traveling faster than 40 mph, one additional second is added, making four seconds under the stated conditions.

Question 6

Which item is not included in the required federal emergency equipment for a commercial bus?

  1. A A fire extinguisher meeting the required rating
  2. B An approved set of warning devices for a stopped vehicle
  3. C A securely mounted and readily accessible required fire extinguisher
  4. D A general-purpose repair tool kit

Correct answer: D – A general-purpose repair tool kit

Federal equipment rules require buses to carry a properly rated fire extinguisher and an authorized set of warning devices for stopped vehicles. The extinguisher must be charged, accessible, and securely mounted. The rule does not require a general-purpose repair tool kit, although a carrier may choose to provide one.
