Sample North Dakota CDL Test Questions - General Knowledge

Question 1

Which condition is acceptable during an inspection of the brakes and suspension?

  1. A Brake shoes and pads are free of oil, grease, and brake fluid
  2. B One missing leaf in a leaf spring can be ignored
  3. C A cracked spring hanger does not need repair
  4. D All of these conditions are acceptable

Correct answer: A – Brake shoes and pads are free of oil, grease, and brake fluid

Brake shoes or pads must not be contaminated with oil, grease, or brake fluid because contamination can reduce braking effectiveness. Cracked or broken spring hangers are suspension defects. A missing or broken leaf can also be dangerous, even when the number missing is not enough by itself to place the vehicle out of service.

Question 2

You are approaching a downhill off-ramp that curves while driving a heavy commercial vehicle. What should you do?

  1. A Rely on the posted ramp speed because it is set for the heaviest vehicles
  2. B Reduce to a safe speed before reaching the curve
  3. C Accelerate before entering the curve
  4. D Wait until you are in the curve to downshift

Correct answer: B – Reduce to a safe speed before reaching the curve

Ramp speed signs may indicate a speed suitable for automobiles but not for a large or heavily loaded commercial vehicle. A downhill curve is especially hazardous because the downgrade makes slowing more difficult. Reduce to a safe speed before reaching the curved portion of the ramp rather than braking and turning at the same time.

Question 3

During an air-pressure buildup check at operating rpm, a dual air system should build between which pressures within 45 seconds?

  1. A From 85 to 100 psi
  2. B From 40 to 60 psi
  3. C From 60 to 80 psi
  4. D From 100 to 120 psi

Correct answer: A – From 85 to 100 psi

The North Dakota CDL manual specifies that a dual air system should build from 85 to 100 psi within 45 seconds when the engine is running at operating rpm. A vehicle with larger-than-minimum air tanks may require more time and still be safe. In that situation, follow the manufacturer's specifications.

Question 4

A white rectangular parking sign displaying the International Symbol of Accessibility indicates:

This sign indicates ___________.
  1. A A parking space reserved for persons with disabilities
  2. B Parking is prohibited for every vehicle
  3. C The space is available to any driver
  4. D Parking is permitted for a limited time

Correct answer: A – A parking space reserved for persons with disabilities

The Accessible Parking sign designates a parking space reserved for persons with disabilities. It displays the official International Symbol of Accessibility. A VAN ACCESSIBLE plaque may be installed below it when the space is designed to accommodate a wheelchair-accessible van.

Question 5

When driving a commercial vehicle at night, which speed practice should you follow?

  1. A Use caffeine so you can maintain your daytime speed
  2. B Increase speed to reduce the time spent driving after dark
  3. C Open a window whenever you begin feeling sleepy
  4. D Drive slowly enough to stop within the distance illuminated by your headlights

Correct answer: D – Drive slowly enough to stop within the distance illuminated by your headlights

North Dakota's CDL manual instructs drivers to match their speed to their headlight sight distance. At night, headlights reveal much less roadway than daylight does. If your stopping distance extends beyond the illuminated area, you may see a hazard too late to stop. Sleep is the only safe remedy when you become drowsy.

Question 6

Which statement correctly describes how vehicle weight affects braking?

  1. A As vehicle weight increases, the brakes must do more work and absorb more heat
  2. B Brakes gain stopping power as they become extremely hot
  3. C Continuous heavy braking is preferred on long downgrades
  4. D Brake drums cool immediately during repeated braking

Correct answer: A – As vehicle weight increases, the brakes must do more work and absorb more heat

Stopping a heavier vehicle requires the brakes to perform more work and absorb more heat. Excessive heat caused by overusing the brakes can produce brake fade or failure. On a long or steep downgrade, engine braking should control most of the vehicle's speed while the service brakes provide supplemental braking.
