Sample Virginia Combination Test Questions

Question 1

Why must a combination-vehicle driver account for off-tracking when turning?

  1. A. It determines the vehicle’s fuel consumption
  2. B. It reduces tire wear during straight-line driving
  3. C. It causes the rear wheels to follow a different path through the turn
  4. D. It changes the fifth wheel’s locking position

Correct answer: C. – It causes the rear wheels to follow a different path through the turn

The Virginia CDL manual describes off-tracking as the rear wheels following a different path from the front wheels around a corner. A trailer’s rear wheels off-track more than the powered unit, and longer combinations off-track more. The driver must allow enough turning room to keep the rear wheels from striking curbs, pedestrians, or other objects.

Question 2

Which procedure verifies that air reaches both lines at the rear of the last trailer?

  1. A. Open the emergency and service shut-off valves at the rear of the last trailer, one at a time
  2. B. Open both shut-off valves at the rear of the tractor
  3. C. Accelerate and make a hard brake application
  4. D. Shut off the engine and listen only at the tractor

Correct answer: A. – Open the emergency and service shut-off valves at the rear of the last trailer, one at a time

After securing the vehicle and charging the system, open the emergency-line valve at the rear of the last trailer and listen for escaping air, then close it. Apply service pressure and repeat the check with the service-line valve. Air must reach the rear through both lines for all trailer brakes to operate properly.

Question 3

Which practices help reduce the risk of a combination-vehicle rollover?

  1. A. Keep the cargo low and centered
  2. B. Reduce speed before and through turns
  3. C. Make steering and lane changes smoothly
  4. D. All of the above

Correct answer: D. – All of the above

A high or off-center load raises rollover risk by making the vehicle less stable. Drivers should keep cargo low and centered, slow down for corners and ramps, and avoid abrupt steering or quick lane changes. These precautions are important whether the combination is fully loaded or empty.

Question 4

What is a possible result if a semitrailer is positioned too high during coupling?

  1. A. The trailer will immediately begin rolling
  2. B. The air lines cannot be connected
  3. C. The electrical cord cannot reach the trailer
  4. D. The kingpin may not couple correctly with the fifth wheel

Correct answer: D. – The kingpin may not couple correctly with the fifth wheel

The Virginia coupling procedure requires the trailer to be low enough that the tractor raises it slightly while backing under it. If the trailer is too high, the kingpin may not couple correctly with the fifth wheel. Adjust the landing gear until the trailer is at the proper height before continuing.

Question 5

How should you check that the trailer emergency brakes apply?

  1. A. Open both air-line valves at the rear of the trailer
  2. B. Place the trailer air supply control in emergency and pull gently against the trailer
  3. C. Turn off the engine and repeatedly press the brake pedal
  4. D. Release every parking brake and pull forward

Correct answer: B. – Place the trailer air supply control in emergency and pull gently against the trailer

First charge the trailer air system and verify that the trailer rolls freely. Stop, pull out the trailer air supply control or place it in the emergency position, and then pull gently with the tractor. Resistance from the trailer confirms that its emergency brakes have applied.

Question 6

Before backing the tractor under a semitrailer, which condition must be verified?

  1. A. The tractor protection valve is in the normal position
  2. B. All trailer brakes are released
  3. C. The trailer landing gear is fully raised
  4. D. The trailer brakes are locked

Correct answer: D. – The trailer brakes are locked

Before backing under the trailer, make sure air pressure is normal and lock the trailer brakes. Pull out the trailer air supply knob or move the tractor protection valve control to the emergency position. Back under the trailer slowly in the lowest reverse gear after the trailer is secured.
