Sample North Dakota CDL Test Questions - General Knowledge

Question 1

A fire extinguisher rated B:C is intended for which types of fires?

  1. A. Burning liquids and energized electrical equipment
  2. B. Cooking oils and animal fats
  3. C. Wood, paper, and cloth
  4. D. Combustible metals only

Correct answer: A. – Burning liquids and energized electrical equipment

The North Dakota CDL manual states that a B:C extinguisher is suitable for burning liquids and electrical equipment fires. Class B covers materials such as gasoline, oil, and grease, while Class C involves energized electrical equipment. An A:B:C extinguisher also covers ordinary combustibles such as wood, paper, and cloth.

Question 2

Which pair is identified as common causes of commercial-vehicle tire fires?

  1. A. High speed and frequent lane changes
  2. B. Overinflation and sharp turns
  3. C. Vehicle weight and rough pavement
  4. D. Underinflated tires and touching dual tires

Correct answer: D. – Underinflated tires and touching dual tires

Underinflated tires flex excessively and can build dangerous heat while the vehicle is moving. Dual tires that touch can rub together and generate additional heat. The CDL manual lists both underinflation and touching duals as causes of tire fires, making proper inflation and spacing important inspection points.

Question 3

What should you do if a hydraulic brake system loses pressure?

  1. A. Shift to a lower gear
  2. B. Pump the brake pedal
  3. C. Control the parking brake while searching for an escape route
  4. D. Use all of these actions as conditions require

Correct answer: D. – Use all of these actions as conditions require

A lower gear can help reduce speed, and pumping the brake pedal may generate enough hydraulic pressure for limited braking. Because the parking or emergency brake is separate from the hydraulic system, it may also be used with carefully controlled pressure. While slowing, look for an open field, side road, upgrade, or escape ramp.

Question 4

Which statement describes a safe practice when backing a commercial vehicle?

  1. A. If a trailer drifts, turn the top of the wheel away from the drift
  2. B. Avoid backing whenever a forward exit is available
  3. C. Position a helper where the driver cannot see the helper
  4. D. Backing is generally safer than moving forward

Correct answer: B. – Avoid backing whenever a forward exit is available

Because a driver cannot see everything behind a commercial vehicle, backing should be avoided whenever possible. When parking, select a position that allows you to pull forward when leaving. If backing is necessary, inspect the path, back slowly, use both mirrors, and use a visible helper when available.

Question 5

On a below-freezing North Dakota roadway, what is black ice?

  1. A. A thin, clear ice layer through which the pavement remains visible
  2. B. A ridge of partly melted ice beside the roadway
  3. C. Dark snow packed along the shoulder
  4. D. Ice that does not reduce tire traction

Correct answer: A. – A thin, clear ice layer through which the pavement remains visible

Black ice is a thin, clear layer that allows the pavement underneath to remain visible. It often makes the road appear wet rather than frozen. When the temperature is below freezing and the pavement looks wet, treat the surface as potentially icy and reduce speed accordingly.

Question 6

What term describes the different paths followed by the front and rear wheels of a long vehicle during a turn?

  1. A. Jackknifing
  2. B. Sidetracking
  3. C. Offtracking
  4. D. Fishtailing

Correct answer: C. – Offtracking

Offtracking occurs when a vehicle's rear wheels follow a different path from its front wheels while turning. Longer vehicles offtrack more, and the trailer's rear wheels may offtrack more than the tractor's rear wheels. Drivers must allow enough turning space while keeping the vehicle's rear from striking curbs, pedestrians, or other vehicles.
