Sample Wyoming CDL Test Questions - General Knowledge

Question 1

What is the minimum tread-groove depth for a commercial vehicle tire that is not on a front wheel?

  1. A. 4/32 inch
  2. B. 2/32 inch
  3. C. 7/16 inch
  4. D. 3/8 inch

Correct answer: B. – 2/32 inch

Federal equipment regulations require at least 2/32 inch of tread-groove depth for commercial vehicle tires other than those covered by the front-wheel rule. Front tires on buses, trucks, and truck tractors require at least 4/32 inch. These minimums apply to commercial vehicles operating in Wyoming, with measurements taken in a major tread groove away from tie bars, humps, or fillets.

Question 2

After selecting a proper low gear on a long, steep downgrade, how should you use the service brakes?

  1. A. Apply them continuously to hold the safe speed
  2. B. Avoid using them under all circumstances
  3. C. Brake to about 5 mph below the safe speed, release, and repeat as speed returns
  4. D. Use the parking brake together with engine braking

Correct answer: C. – Brake to about 5 mph below the safe speed, release, and repeat as speed returns

Apply the brakes firmly enough to produce a definite slowdown. When the vehicle reaches approximately 5 mph below the selected safe speed, release the brakes; the application should last about three seconds. When the vehicle returns to the safe speed, repeat the process while continuing to use the engine’s braking effect.

Question 3

At a flashing red traffic signal in Wyoming, what must a driver do?

  1. A. Stop and proceed under the same rules that apply at a stop sign
  2. B. Slow down but continue without stopping if the road appears clear
  3. C. Continue as though facing a steady green signal
  4. D. Treat the signal as a yield sign

Correct answer: A. – Stop and proceed under the same rules that apply at a stop sign

Wyoming law requires a driver facing a flashing red signal to stop before the crosswalk, stop line, or intersection, as applicable. After stopping, the driver may proceed subject to the rules that apply after stopping at a stop sign. A flashing yellow signal, not a flashing red one, permits cautious movement without a required stop.

Question 4

Which action describes controlled braking during an emergency stop?

  1. A. Using the technique only when the vehicle lacks ABS
  2. B. Braking as hard as possible without locking the wheels
  3. C. Locking the wheels, releasing, and then fully reapplying the brakes
  4. D. Holding the brakes down after all wheels have locked

Correct answer: B. – Braking as hard as possible without locking the wheels

Controlled braking means applying the brakes as hard as possible without locking the wheels. Steering movements should remain very small during the stop. If the wheels lock or a larger steering correction is necessary, release the brakes and reapply them as soon as control permits.

Question 5

Which situation may require selecting a lower gear?

  1. A. Before starting down a steep grade
  2. B. Before entering a curve
  3. C. While climbing when a lower gear is needed to maintain engine speed
  4. D. All of the above

Correct answer: D. – All of the above

Select a proper low gear before beginning a steep downgrade and before entering a curve. Waiting until speed has built on a downgrade can make it difficult or impossible to engage the needed gear. On an upgrade, heavier loads and steeper grades may require progressively lower gears to keep the engine operating effectively.

Question 6

What should a commercial driver do when sleepiness begins?

  1. A. Pull off at a safe place and sleep
  2. B. Take a nap in a safe location
  3. C. Avoid using drugs as a substitute for sleep
  4. D. All of the above

Correct answer: D. – All of the above

A sleepy driver should stop driving and get rest or take a nap in a safe location. Drugs may temporarily keep someone awake, but they do not restore alertness and are not a substitute for sleep. Medications that cause drowsiness should also be avoided before driving.
