Sample North Carolina CDL Test Questions - General Knowledge

Question 1

A small cardboard carton is lying in your lane. If traffic and clearance permit, what should you do?

  1. A Stop in the travel lane and direct traffic
  2. B Strike it to push it off the roadway
  3. C Steer around it with a smooth, safe maneuver
  4. D Place a steering tire directly over it

Correct answer: C – Steer around it with a smooth, safe maneuver

The North Carolina manual warns that a cardboard box may contain solid or heavy material capable of damaging a vehicle. Road debris can also harm tires, wheel rims, brake lines, or electrical lines. Scan far enough ahead to avoid the object smoothly rather than making a sudden, unsafe maneuver.

Question 2

You feel drowsy before beginning a trip. What is the safest action?

  1. A Eat a large meal
  2. B Get some sleep
  3. C Drink coffee and begin driving
  4. D Exercise briefly before leaving

Correct answer: B – Get some sleep

If you are drowsy, sleep before driving. The CDL manual describes sleep as the only safe cure for drowsiness and advises a sleepy driver to stop at the nearest safe place. Coffee, exercise, food, or drugs cannot replace the rest needed for safe driving.

Question 3

When should you select a lower range in a CMV with an automatic transmission?

  1. A Before beginning a downgrade
  2. B After starting an upgrade
  3. C While traveling through a curve
  4. D After leaving a curve

Correct answer: A – Before beginning a downgrade

Select a low range before starting down a grade. A lower range provides greater engine braking and prevents the transmission from shifting above the selected gear, unless governed rpm is exceeded. Waiting until speed has built up may prevent a successful downshift and can reduce the available engine-braking effect.

Question 4

Which practice helps you avoid overdriving your headlights at night?

  1. A Use high beams continuously
  2. B Look directly into approaching headlights
  3. C Keep your stopping distance within the illuminated roadway
  4. D Keep the instrument panel at maximum brightness

Correct answer: C – Keep your stopping distance within the illuminated roadway

At night, adjust your speed so your stopping distance remains within the distance illuminated by your headlights. Low beams normally provide less sight distance than high beams, making excessive speed especially dangerous. Looking into approaching headlights or using bright interior lighting can make it harder to see the roadway.

Question 5

When must a CMV driver be satisfied that safety-critical parts and accessories are in good working order?

  1. A At least once each week
  2. B At least once each day
  3. C Only after a problem was reported
  4. D Before driving the vehicle

Correct answer: D – Before driving the vehicle

Before driving, the driver must be satisfied that required equipment—including brakes, steering, lights, tires, mirrors, coupling devices, wheels, and emergency equipment—is in good working order. Federal regulation 49 CFR § 392.7 establishes this requirement. The North Carolina vehicle-inspection procedure helps drivers find defects that could cause a crash or breakdown.

Question 6

Before backing with a helper, which hand signal is most important for both people to understand?

  1. A Pull forward
  2. B Begin backing
  3. C Continue moving
  4. D Stop

Correct answer: D – Stop

Before backing begins, the driver and helper should agree on a clear set of hand signals, especially the signal for “stop.” The helper should stand near the rear of the vehicle where the driver can see them. A clearly understood stop signal allows the helper to warn the driver before the vehicle reaches a hazard.
