Sample Nevada CDL Test Questions - General Knowledge

Question 1

What does a parking sign displaying the international wheelchair-access symbol indicate?

This sign indicates ___________.
  1. A The space is reserved for an authorized person with a disability.
  2. B Parking is prohibited for every vehicle.
  3. C The space is open to any vehicle.
  4. D Parking is permitted only for a limited time.

Correct answer: A – The space is reserved for an authorized person with a disability.

Question 2

Which vehicle is generally required to stop before crossing railroad tracks?

  1. A Every commercial motor vehicle without exception
  2. B A passenger bus or a vehicle carrying regulated hazardous materials
  3. C Only a commercial vehicle traveling after dark
  4. D Only a commercial vehicle approaching an unmarked crossing

Correct answer: B – A passenger bus or a vehicle carrying regulated hazardous materials

Nevada law generally requires a bus carrying passengers, a school bus carrying a child, or a vehicle carrying regulated hazardous materials to stop at railroad tracks. The stop must be within 50 feet but not less than 15 feet from the nearest rail. Certain controlled, abandoned, industrial, or officially exempt crossings are exceptions.

Question 3

What does “off-tracking” mean when a combination vehicle turns?

  1. A The vehicle leaves a paved roadway.
  2. B The tractor passes traffic on the right.
  3. C The trailer temporarily travels on the shoulder.
  4. D The rear wheels follow a different path from the front wheels.

Correct answer: D – The rear wheels follow a different path from the front wheels.

During a turn, the rear wheels do not follow exactly the same path as the front wheels. This inward difference is called off-tracking, sometimes called cheating. Drivers must account for it because the rear portion of a long vehicle can strike a curb, vehicle, or other object even when the front clears it.

Question 4

What is a commercial driver’s primary tool for monitoring traffic beside and behind the vehicle?

  1. A A backing helper
  2. B The mirrors
  3. C The turn signals
  4. D The horn

Correct answer: B – The mirrors

Regular mirror checks help a commercial driver monitor traffic beside and behind the vehicle. Mirrors should be checked more often during lane changes, turns, merges, and tight maneuvers. Because mirrors cannot display every blind spot, the driver must also understand their limitations and remain alert to vehicles that disappear from view.

Question 5

Which description best identifies black ice?

  1. A A thin, nearly transparent layer of ice through which the pavement remains visible
  2. B A pile of melting ice beside the roadway
  3. C Snow packed only along the shoulder
  4. D Harmless frost that cannot affect vehicle control

Correct answer: A – A thin, nearly transparent layer of ice through which the pavement remains visible

Black ice is a thin, clear layer through which the road surface can still be seen. It often makes the pavement look wet rather than frozen, making it difficult to recognize. When temperatures are below freezing and the roadway appears wet, a commercial driver should watch carefully for black ice.

Question 6

If the normal speed is 55 mph and the road becomes wet, approximately what speed does the CDL handbook recommend?

  1. A 35 mph
  2. B 55 mph
  3. C 45 mph
  4. D 25 mph

Correct answer: A – 35 mph

The Nevada CDL handbook recommends reducing speed by about one-third on a wet road, using a reduction from 55 mph to about 35 mph as its example. Wet pavement can double stopping distance and makes turning without skidding more difficult. Further reduction may be necessary when visibility, traffic, or traction is especially poor.
