Sample Nevada CDL Test Questions - General Knowledge

Question 1

An 8-foot cargo article is not blocked or positioned against forward movement. What is the minimum number of tiedowns required?

  1. A 1
  2. B 2
  3. C 3
  4. D 4

Correct answer: B – 2

An article longer than 5 feet but no longer than 10 feet must have at least two tiedowns when it is not blocked or positioned to prevent forward movement. The rule applies regardless of the article’s weight within that length category. Different minimums apply to shorter articles and to cargo that is properly blocked, braced, or immobilized.

Question 2

An underinflated tire can contribute to a vehicle fire.

  1. A True
  2. B False

Correct answer: A – True

Underinflated tires are identified as a possible cause of commercial-vehicle fires. During a trip, inspect tires and wheels for signs of excessive heat whenever you stop, and use the mirrors to watch for smoke. Maintaining correct tire pressure and correcting tire defects are important parts of fire prevention.

Question 3

Cargo blocking is used to help prevent a load from sliding.

  1. A True
  2. B False

Correct answer: A – True

Blocking may be placed at the front, rear, or sides of an article to keep it from sliding. It should fit snugly against the cargo and be secured to the deck. Bracing also prevents movement, but it generally extends from the upper portion of the cargo to the floor or walls of the cargo compartment.

Question 4

If a vehicle does not have automatic air-tank drains, when should the tanks be drained?

  1. A At the end of every working day
  2. B Once each month
  3. C Every six months
  4. D Once each year

Correct answer: A – At the end of every working day

The Nevada CDL manual directs drivers to drain air tanks at the end of each working day unless the vehicle has automatic drains. Draining removes moisture and oil that collect in the tanks. Allowing these materials to remain in the system can interfere with air-brake operation and may contribute to brake failure.

Question 5

What should you do with the space ahead when another driver is tailgating your commercial vehicle?

  1. A Reduce it to discourage passing
  2. B Brake sharply to warn the following driver
  3. C Increase your following distance
  4. D Maintain speed while signaling the driver to pass

Correct answer: C – Increase your following distance

Increase the space between your vehicle and the vehicle ahead when you are being tailgated. The added room allows you to slow or change direction more gradually if a hazard develops. Signal early, avoid sudden changes, and do not speed up or use brake-light tricks to confront the following driver.

Question 6

Why should a driver position the vehicle for driver-side backing whenever practical?

  1. A Traffic law always requires it
  2. B It guarantees that the maneuver will take less time
  3. C It provides a better view of the vehicle’s rear path
  4. D It eliminates the need to check the passenger-side mirror

Correct answer: C – It provides a better view of the vehicle’s rear path

The Nevada CDL manual recommends backing toward the driver’s side because visibility is better. The driver can watch the rear of the vehicle through the side window while continuing to use the mirrors. Passenger-side backing creates a larger blind area and should be avoided when the vehicle can reasonably be repositioned for a safer approach.
