This CDL practice test, designed to mirror the format and style of the actual North Dakota DMV permit test, features 20 carefully curated questions. To pass, you must correctly answer at least 16 questions, reflecting the DMV's requirement of an 80% passing score. Our North Dakota CDL practice test adopts a multiple-choice and true/false format, identical to what you'll encounter at the DMV. This familiarizes you with the testing method, honing your skills in identifying the correct answer amidst plausible alternatives. The format is straightforward yet effective, allowing you to focus on content mastery rather than adjusting to a new testing style. One of the standout features of this ND DMV practice test is its randomized question sets. Each time you take this CDL prep test, you'll encounter the same set of sample permit test questions, but the order of the questions will be randomized. This approach is critical in ensuring that you're not just memorizing the sequence of drivers test questions and answers, but truly understanding the underlying principles and knowledge required for the CDL. It's a dynamic way to prepare, keeping you engaged and alert to new challenges. Furthermore, we believe in learning from every attempt.

This aspect of the North Dakota practice prep test is invaluable in deepening your understanding of the material. It's not just about knowing the right answer to a DMV question, but understanding why it's right, and why other options are not. These explanations are tailored to reinforce your learning and clarify any misconceptions. We encourage you to utilize this resource as part of your preparation strategy.

Sample North Dakota CDL Test Questions - General Knowledge

Question 1

On a very slippery surface, how should you correct a rear drive-wheel acceleration skid?

  1. A. Apply more power to the drive wheels
  2. B. Turn the steering wheel sharply away from the skid
  3. C. Release the accelerator and depress the clutch
  4. D. Apply the service brakes firmly

Correct answer: C. – Release the accelerator and depress the clutch

Acceleration skids commonly occur on ice or snow when excessive power causes the drive wheels to spin. Remove your foot from the accelerator to reduce power to those wheels. If the surface is very slippery, depress the clutch so the engine does not prevent the wheels from rolling freely and regaining traction.

Question 2

In a manual-transmission commercial vehicle stopped on an upgrade, what should you do before moving your right foot from the brake pedal?

  1. A. Place a wheel chock in front of a tire
  2. B. Shift into neutral
  3. C. Partly engage the clutch
  4. D. Release the clutch completely

Correct answer: C. – Partly engage the clutch

Partly engage the clutch before moving your right foot from the brake pedal. This begins applying engine power and helps prevent the vehicle from rolling backward. The parking brake may also be used when necessary, but it should not be released until enough engine power has been applied to hold the vehicle.

Question 3

For safe vehicle handling, how should cargo weight be distributed from front to rear?

  1. A. Centered and properly balanced in the cargo area
  2. B. Concentrated toward the front
  3. C. Concentrated toward the rear
  4. D. Placed over whichever axle has the highest rating

Correct answer: A. – Centered and properly balanced in the cargo area

The North Dakota CDL manual emphasizes balancing cargo in the cargo area. Excessive weight on the steering axle can make steering difficult and damage the axle or tires. Cargo placed too far rearward can leave the steering axle too lightly loaded for safe control, while insufficient weight on the drive axles can reduce traction.

Question 4

What does perception distance measure?

  1. A. The distance traveled while moving your foot from the accelerator to the brake
  2. B. The distance traveled from seeing a hazard until your brain recognizes it
  3. C. The distance traveled after the brakes begin slowing the vehicle
  4. D. The time required to bring the vehicle to a complete stop

Correct answer: B. – The distance traveled from seeing a hazard until your brain recognizes it

Perception distance is the distance a vehicle travels from the moment the driver sees a hazard until the brain recognizes it. It is separate from reaction distance and braking distance. Visibility, alertness, and the nature of the hazard can affect how quickly the driver recognizes danger.

Question 5

What should you do before entering a curve in a heavy vehicle?

  1. A. Reduce to a safe speed and select the proper gear
  2. B. Accelerate and shift after entering the curve
  3. C. Stop before every curve

Correct answer: A. – Reduce to a safe speed and select the proper gear

The North Dakota CDL manual instructs drivers to slow to a safe speed and downshift to the proper gear before entering a curve. Selecting the gear beforehand permits some power to be applied through the curve, helping vehicle stability. Braking or shifting after entering can interfere with smooth control.

Question 6

Under which road condition should a vehicle retarder be turned off?

  1. A. When the road is wet, icy, or covered with snow
  2. B. Whenever the driver slept fewer than six hours
  3. C. Whenever the vehicle is carrying liquid cargo
  4. D. Under all of these conditions

Correct answer: A. – When the road is wet, icy, or covered with snow

A retarder can cause the drive wheels to skid when traction is poor. Turn it off on wet, icy, or snow-covered roads. This is especially important because a retarder may apply braking force whenever the accelerator is fully released, depending on how the system is set.
