Sample North Carolina CDL Test Questions - General Knowledge

Question 1

Which practices can help a commercial driver remain alert?

  1. A Get adequate sleep and schedule travel during normal waking hours
  2. B Include exercise in your routine and avoid heavy foods while driving
  3. C Avoid drowsiness-causing medicines and consult a physician about recurring sleepiness
  4. D All of the above

Correct answer: D – All of the above

Question 2

About how far ahead do low-beam headlights normally illuminate the road?

  1. A 250 feet
  2. B 200 feet
  3. C 150 feet
  4. D 350 feet

Correct answer: A – 250 feet

Low-beam headlights normally allow you to see about 250 feet ahead. Your speed must permit you to stop within the distance illuminated by your headlights. Otherwise, a hazard may become visible too late for you to stop safely.

Question 3

If an emergency forces your commercial vehicle onto the shoulder, how should you slow down if conditions permit?

  1. A Brake hard immediately after leaving the pavement
  2. B Move every wheel off the pavement before reducing speed
  3. C Let your speed fall to about 20 mph, then brake gently
  4. D Steer back onto the pavement before slowing

Correct answer: C – Let your speed fall to about 20 mph, then brake gently

If possible, avoid braking until the vehicle slows to approximately 20 mph. Then apply the brakes very gently because a loose shoulder surface may provide less traction. Keeping one set of wheels on the pavement, when possible, can also help maintain control.

Question 4

In North Carolina CDL weight terminology, what does the abbreviation GVW represent?

  1. A Government vehicle weight
  2. B Gross variable weight
  3. C Gross vehicle width
  4. D Gross vehicle weight

Correct answer: D – Gross vehicle weight

GVW is the abbreviation for gross vehicle weight. It should not be confused with GVWR, which stands for gross vehicle weight rating and refers to the manufacturer-specified loaded weight rating of a single vehicle.
