Sample West Virginia Combination Test Questions

Question 1

During a coupling inspection, the fifth-wheel jaws are around the kingpin, but the locking lever is not in the locked position. What must you do?

  1. A Release the trailer brakes and begin driving slowly
  2. B Secure only the safety latch and continue
  3. C Correct the coupling problem before driving
  4. D Move the sliding fifth wheel to balance the load

Correct answer: C – Correct the coupling problem before driving

The fifth-wheel locking lever must be in its locked position, with the safety latch properly placed, before the combination is driven. West Virginia's manual directs the driver not to operate the unit if the coupling is incorrect. The connection must be inspected and corrected before departure.

Question 2

Which valve helps reduce air-brake application lag by quickly sending trailer-tank air to the trailer brakes?

  1. A Quick-release valve
  2. B Relay valve
  3. C Front-wheel limiting valve
  4. D Tractor protection valve

Correct answer: B – Relay valve

The service air line is connected to relay valves on the trailer. Service-line pressure tells the relay valves how much air pressure to send from the trailer tanks to the brakes. Using air stored near the trailer brakes allows them to apply more quickly than they would if application air had to travel directly from the tractor.

Question 3

After coupling a tractor and semitrailer, how should the landing gear be positioned before driving?

  1. A One-quarter raised, with the crank secured
  2. B Halfway raised, with the crank secured
  3. C Raised only until it clears the pavement
  4. D Fully raised, with the crank secured

Correct answer: D – Fully raised, with the crank secured

Raise the landing gear completely before driving and secure the crank handle. Landing gear left only partly raised can catch on railroad tracks or other objects and be damaged. The walk-around inspection should also confirm that the gear is fully raised, undamaged, and securely assembled.

Question 4

What does off-tracking describe when a combination vehicle turns?

  1. A The tractor leaves the roadway while the trailer stays in its lane
  2. B The trailer begins moving in the opposite direction
  3. C The rear wheels follow a different path from the front wheels
  4. D The vehicle travels on an unpaved road

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

Off-tracking occurs because the rear wheels follow a different path from the front wheels while turning. The West Virginia manual also refers to this effect as “cheating.” Longer vehicles off-track more, and the rear wheels of a trailer generally track farther inward than the tractor's rear wheels.

Question 5

If a trailer is too high for correct fifth-wheel coupling, what should you do?

  1. A Raise the trailer farther
  2. B Back under it at a higher speed
  3. C Approach the trailer at an angle
  4. D Lower the trailer to the proper coupling height

Correct answer: D – Lower the trailer to the proper coupling height

Lower the trailer until it is positioned so the tractor will raise it slightly while backing underneath. If the trailer is too high, the fifth wheel may not couple correctly. If it is too low, the tractor can strike and damage the trailer nose, so the height must be adjusted before completing the connection.

Question 6

Which procedure correctly tests the trailer emergency brakes?

  1. A Charge the trailer system, verify the trailer rolls, pull out the trailer air-supply control, and tug gently against the brakes
  2. B Move forward slowly and apply only the trailer hand valve
  3. C Fan the foot brake until the low-air warning activates
  4. D Check the trailer's ABS lamp without moving the vehicle

Correct answer: A – Charge the trailer system, verify the trailer rolls, pull out the trailer air-supply control, and tug gently against the brakes

First charge the trailer air system and confirm that the trailer rolls freely. Stop, pull out the trailer air-supply control or place it in the emergency position, then pull gently against the trailer. The resistance verifies that the trailer emergency brakes have applied; using the hand valve while moving slowly is the test for the trailer service brakes.
