Sample Nevada CDL Test Questions - General Knowledge

Question 1

What should you do before driving if you are drowsy?

  1. A Eat a large meal
  2. B Sleep or take a nap
  3. C Rely on coffee to remain alert
  4. D Exercise briefly and begin driving

Correct answer: B – Sleep or take a nap

If you are drowsy, sleep before driving. Even a nap can improve alertness and may prevent a fatigue-related crash. Do not begin or continue a trip when you cannot remain alert enough to observe hazards and control the vehicle safely.

Question 2

Which of these can cause a commercial vehicle to skid?

  1. A Over-steering
  2. B Over-braking
  3. C Driving too fast for conditions
  4. D All of these

Correct answer: D – All of these

The Nevada CDL manual identifies over-braking, over-steering, over-acceleration, and excessive speed for conditions as causes of skids. Hard braking can lock the wheels, while excessive steering can demand more traction than the tires have available. Driving at a safe speed reduces the need for sudden braking, acceleration, or steering corrections.

Question 3

Which statements correctly describe required hazardous-material placards?

  1. A They are displayed on the front, rear, and both sides of the vehicle.
  2. B They measure at least 250 mm (9.84 inches) on each side.
  3. C They are square-on-point, forming a diamond shape.
  4. D All of the above.

Correct answer: D – All of the above.

A vehicle required to display hazardous-material placards generally has them on each side and each end. Each placard must measure at least 250 mm, or 9.84 inches, on each side. Its square-on-point orientation creates the familiar diamond shape used to communicate the cargo’s hazard class.

Question 4

Which practice is recommended when operating a commercial vehicle?

  1. A Back toward the passenger side whenever possible.
  2. B Avoid backing when a forward exit can be arranged.
  3. C Use only spoken directions from a helper.
  4. D Back quickly to spend less time in the blind area.

Correct answer: B – Avoid backing when a forward exit can be arranged.

The Nevada CDL handbook advises drivers to avoid backing whenever possible because they cannot see everything behind the vehicle. When parking, choose a position that will allow you to pull forward when leaving. If backing is necessary, inspect the path, move slowly, use both mirrors, and use a helper when available.

Question 5

A 40-foot commercial vehicle is traveling at 50 mph. What minimum following interval should the driver maintain?

  1. A 3 seconds
  2. B 4 seconds
  3. C 7 seconds
  4. D 5 seconds

Correct answer: D – 5 seconds

Allow at least one second for every 10 feet of vehicle length when traveling below 40 mph. At higher speeds, add one additional second. A 40-foot vehicle requires four seconds based on length, plus one second because the speed exceeds 40 mph, for a total of at least five seconds.

Question 6

What type of information is normally shown on a brown highway sign?

  1. A Recreation or scenic-area information
  2. B A general traffic warning
  3. C A traffic law or regulation
  4. D Emergency medical services only

Correct answer: A – Recreation or scenic-area information

The Nevada Driver’s Handbook identifies brown as the standard color for recreation and scenic-area information. These signs may direct travelers toward parks, campgrounds, historic locations, or similar attractions. Regulatory signs are normally white, while general warning signs are typically yellow or yellow-green.
