Sample Wyoming CDL Test Questions - General Knowledge

Question 1

When operating a bus, properly secured baggage and freight must meet which conditions?

  1. A. The driver can move freely and easily
  2. B. Riders can use any emergency door or window
  3. C. Riders are protected if carry-ons fall or shift
  4. D. All of the above

Correct answer: D. – All of the above

Baggage must be secured so the driver can move freely, riders can use any emergency exit, and shifting items do not injure passengers. Doorways and aisles must also remain clear of carry-on baggage. These requirements are included in the Wyoming CDL manual’s passenger-vehicle loading guidance.

Question 2

Approximately how far ahead do properly operating high-beam headlights illuminate the road?

  1. A. 350 to 500 feet
  2. B. 100 to 200 feet
  3. C. 200 to 300 feet
  4. D. 500 to 700 feet

Correct answer: A. – 350 to 500 feet

The Wyoming CDL manual estimates that high beams illuminate approximately 350 to 500 feet ahead, while low beams reach about 250 feet. At night, adjust speed so the vehicle can stop within the illuminated distance. Dirty or improperly aimed headlights can substantially reduce the available sight distance.

Question 3

Before entering a downhill exit ramp that curves, what should the driver of a heavy vehicle do?

  1. A. Maintain the ramp’s posted advisory speed
  2. B. Reduce to a safe speed before reaching the curve
  3. C. Wait until entering the curve to downshift
  4. D. Shift into a higher gear before turning

Correct answer: B. – Reduce to a safe speed before reaching the curve

The Wyoming CDL manual warns that a downgrade makes speed reduction more difficult, especially when the ramp also curves. Braking and turning together can increase the risk of losing control. Enter the curved portion slowly enough to complete the turn safely, using the proper gear before the curve.

Question 4

Which group of items should be monitored or checked while a commercial vehicle is in operation?

  1. A. Exhaust smoke, fuel receipts, cargo, and mud flaps
  2. B. Pumps, hoses, shock absorbers, and frame members
  3. C. Instruments, mirrors, tires, cargo or cargo covers, and lights
  4. D. Spring hangers, brake shoes, crossmembers, and the fifth-wheel platform

Correct answer: C. – Instruments, mirrors, tires, cargo or cargo covers, and lights

During a trip, regularly check the instruments, mirrors, tires, cargo and its covers, and lights. Pay attention to anything you see, hear, smell, or feel that may indicate trouble. If something appears unsafe, investigate it rather than waiting until the end of the trip.

Question 5

On a paved Wyoming road where no other maximum speed is specified, the maximum lawful speed for a school bus is:

  1. A. 50 mph
  2. B. 55 mph
  3. C. 45 mph
  4. D. 65 mph

Correct answer: D. – 65 mph

State law sets a 65 mph maximum on paved roads at locations where another maximum is not specified. A lower posted limit must still be followed, and the driver must reduce speed when curves, weather, traffic, or other hazards make 65 mph unsafe. The stated limit is a maximum, not a required traveling speed.

Source: W.S. § 31-5-301(a), (b)(iv) — Maximum speed limits

Question 6

Which sequence correctly describes stab braking in a vehicle without ABS?

  1. A. Apply the brakes fully and keep them applied after the wheels lock
  2. B. Release the brakes when the wheels lock and do not reapply them
  3. C. Pump the brakes lightly before the wheels begin rolling
  4. D. Brake fully, release when the wheels lock, and reapply fully when they roll again

Correct answer: D. – Brake fully, release when the wheels lock, and reapply fully when they roll again

Stab braking begins by applying the brakes fully. If the wheels lock, release the brakes; once the wheels begin rolling again, apply them fully. Reapplying before the wheels roll can prevent the vehicle from straightening. This technique is used for emergency braking in vehicles without ABS.
