Sample North Carolina CDL Test Questions - General Knowledge

Question 1

In defensive commercial driving, what does “communicating” primarily involve?

  1. A Using a mobile phone
  2. B Applying the brakes repeatedly
  3. C Sounding the horn continuously
  4. D Signaling your intentions to other road users

Correct answer: D – Signaling your intentions to other road users

Communicating means giving other road users clear notice of what you intend to do. The North Carolina manual emphasizes early and continuous signaling for turns and lane changes and warns against canceling a signal too soon. Proper communication gives others time to recognize and respond to your planned movement.

Question 2

When using a fire extinguisher on a vehicle fire, should you move as close to the flames as possible?

  1. A Yes
  2. B No

Correct answer: B – No

Do not move as close to the fire as possible. The CDL manual directs drivers to remain as far from the fire as possible while using the extinguisher. Aim the discharge at the source or base of the fire rather than directing it into the upper flames.

Question 3

What does a ROAD NARROWS (W5-1) warning sign indicate?

This sign warns drivers that _____________.
  1. A Traffic-control devices are immediately ahead
  2. B The roadway width decreases ahead
  3. C All driving conditions ahead are hazardous
  4. D The road is about to join a major highway

Correct answer: B – The roadway width decreases ahead

The ROAD NARROWS sign warns that the pavement width decreases ahead. It is used before an abrupt transition on a two-lane road where opposing vehicles may be unable to pass through the narrowed section simultaneously without reducing speed. It does not indicate a highway entrance or a general traffic-control area.

Question 4

What is the proper service-brake technique on a long, steep downgrade after selecting a safe speed and low gear?

  1. A Apply the brakes continuously to hold the safe speed
  2. B Use only engine braking throughout the descent
  3. C Brake to about 5 mph below the safe speed, release, and repeat as speed returns
  4. D Use the parking brake together with engine braking

Correct answer: C – Brake to about 5 mph below the safe speed, release, and repeat as speed returns

Apply the service brakes firmly enough to produce a definite slowdown. When the vehicle reaches approximately 5 mph below the selected safe speed, release the brakes; the application should last about three seconds. When speed increases to the safe speed again, repeat the process. Engine braking remains the principal method of controlling speed on the downgrade.

Question 5

Which choice lists three cargo-related duties assigned to a commercial driver?

  1. A Measuring cargo dimensions, setting its value, and selecting the delivery order
  2. B Inspecting cargo, recognizing overloads or poor balance, and ensuring cargo is secured
  3. C Opening sealed freight, preparing shipping papers, and choosing the route
  4. D Setting freight rates, approving the cargo seal, and scheduling delivery

Correct answer: B – Inspecting cargo, recognizing overloads or poor balance, and ensuring cargo is secured

North Carolina’s CDL manual makes the driver responsible for inspecting cargo, recognizing overloads or poor weight balance, and knowing the load is properly secured. Cargo must not block the driver’s view or access to emergency equipment. Although the contents of a sealed load cannot be inspected, the driver must still check compliance with gross and axle-weight limits.

Question 6

What is the primary purpose of placards displayed on a vehicle carrying regulated hazardous materials?

  1. A To warn others about the hazards presented by the cargo
  2. B To identify a vehicle with air brakes
  3. C To mark every oversize load
  4. D To show the vehicle’s licensed weight

Correct answer: A – To warn others about the hazards presented by the cargo

Placards communicate the hazard associated with regulated cargo to motorists, emergency responders, and others. The North Carolina CDL manual explains that they are exterior signs identifying the cargo’s hazard class. When a vehicle must be placarded, placards are displayed where they are readable from the front, rear, and both sides.
