Sample Wyoming CDL Test Questions - General Knowledge

Question 1

What is the recommended way to grip a commercial vehicle’s steering wheel?

  1. A Firmly with both hands on opposite sides
  2. B Firmly with the dominant hand only
  3. C Loosely with both hands near the bottom
  4. D Loosely with one hand whenever traveling straight

Correct answer: A – Firmly with both hands on opposite sides

Hold the steering wheel firmly with both hands positioned on opposite sides. A curb, pothole, or other road impact can cause the wheel to pull suddenly. A firm two-handed grip helps the driver maintain control when that happens.

Question 2

Which vehicle fire may require large amounts of water for cooling?

  1. A A tire fire
  2. B A gasoline fire
  3. C A diesel-fuel fire
  4. D An energized electrical fire

Correct answer: A – A tire fire

A burning tire must be cooled, and the CDL manual warns that a large amount of water may be necessary. Gasoline and diesel are flammable-liquid fires for which water can spread the burning fuel. Water must not be used on an energized electrical fire because it can conduct electricity and cause shock.

Question 3

A yellow diamond sign displays a black cross symbol. What condition is ahead?

This sign warns drivers to _____________.
  1. A A slow-vehicle route begins on the right
  2. B A detour turns to the right
  3. C A stop is required at the sign
  4. D A crossroad where traffic may enter from either side

Correct answer: D – A crossroad where traffic may enter from either side

The Cross Road warning sign indicates an intersection ahead and the possibility of turning or entering traffic. The horizontal line represents a roadway crossing the driver’s route from both the right and left. The sign warns of the intersection but does not by itself require a stop.

Question 4

On which vehicle is stab braking inappropriate as a wheel-lock-and-release technique?

  1. A A vehicle with air brakes
  2. B A vehicle carrying hazardous materials
  3. C A vehicle towing a trailer
  4. D A vehicle with working anti-lock brakes

Correct answer: D – A vehicle with working anti-lock brakes

Stab braking involves fully applying the brakes, releasing them when the wheels lock, and reapplying them after the wheels begin rolling. ABS is designed to prevent wheel lock by automatically adjusting brake pressure. With working ABS, use the necessary braking force to stop safely and maintain control rather than attempting to produce wheel lock.

Question 5

Should the trailer hand valve be applied before the foot brake during normal driving to prevent a jackknife?

  1. A No, because applying only the trailer brakes can cause a trailer skid
  2. B Yes, because it prevents the trailer wheels from skidding
  3. C Yes, because it allows the driver to steer with both hands
  4. D Yes, because it is the preferred method for straight-line stops

Correct answer: A – No, because applying only the trailer brakes can cause a trailer skid

Do not use the trailer hand valve for normal driving because applying only the trailer brakes can cause the trailer to skid. The foot brake applies the brakes throughout the combination, including the trailer. Using the foot brake presents less danger of a skid or jackknife than relying on the hand valve.

Question 6

If reflective triangles are used as a commercial vehicle’s emergency warning devices, how many must be carried?

  1. A Two
  2. B Four
  3. C One
  4. D Three

Correct answer: D – Three

A commercial power unit using reflective warning devices must carry three red bidirectional reflective triangles. The Wyoming CDL pre-trip procedure instructs drivers to confirm that all three are present. Other permitted warning-device packages may use the specified number of fusees or liquid-burning flares instead.
