Sample Nevada Combination Test Questions

Question 1

How should you test trailer service brakes when the combination has a trailer hand control?

  1. A Build normal pressure, move forward slowly, and apply the trailer brakes with the hand control
  2. B Place the trailer air-supply control in emergency and pull forward
  3. C Shut off the engine and repeatedly press the foot brake
  4. D Release all parking brakes and pull forward without applying another control

Correct answer: A – Build normal pressure, move forward slowly, and apply the trailer brakes with the hand control

Build normal air pressure, release the parking brakes, and move forward slowly. Apply the trailer brakes with the hand control, or trolley valve, if the vehicle has one; you should feel the brakes engage. During normal operation, use the foot brake because it applies the service brakes throughout the combination.

Question 2

How should trailer service- and emergency-line shut-off valves be positioned for travel?

  1. A Every shut-off valve should be open
  2. B Every shut-off valve should be closed
  3. C Valves should be open between units and closed at the rear of the last trailer
  4. D Service-line valves should be open and emergency-line valves closed

Correct answer: C – Valves should be open between units and closed at the rear of the last trailer

Nevada's CDL handbook directs drivers to keep shut-off valves open throughout the combination except at the back of the last trailer. Both the service- and emergency-line valves at the rear of the final trailer must be closed. This arrangement permits air to reach each trailer without escaping from the end of the system.

Question 3

What is the main safety benefit of using a helper when backing a combination vehicle?

  1. A The helper can monitor blind areas and signal the driver
  2. B The helper can make the vehicle back more quickly
  3. C The helper can operate the trailer brakes from outside
  4. D The helper can adjust the mirrors while the vehicle moves

Correct answer: A – The helper can monitor blind areas and signal the driver

A helper can watch blind areas that are not visible from the driver's seat. The helper should stand near the rear where the driver can see them without entering the vehicle's path. Before backing, the driver and helper should agree on clear hand signals, especially a stop signal.

Question 4

Which action tests whether a tractor and semitrailer are securely coupled?

  1. A Accelerate rapidly from a stop
  2. B Make a sharp turn at low speed
  3. C Gently pull forward while the trailer brakes remain applied
  4. D Check only the rearview mirrors

Correct answer: C – Gently pull forward while the trailer brakes remain applied

Raise the trailer landing gear slightly off the ground and keep the trailer brakes applied. Gently pull the tractor forward to confirm that the trailer remains locked to the tractor. This pull test is followed by a visual inspection of the fifth-wheel jaws, locking lever, safety latch, and coupling surfaces.

Question 5

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

  1. A The driver steers onto the shoulder while turning
  2. B The vehicle reverses direction while traveling through a curve
  3. C The rear wheels travel along a different path from the front wheels
  4. D The vehicle leaves a paved road for a gravel surface

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

Nevada's CDL handbook calls the different path followed by the rear wheels off-tracking, sometimes called cheating. Longer vehicles off-track more than shorter vehicles, and trailer wheels generally track farther inside than the tractor's wheels. The driver must allow enough turning clearance to keep the rear wheels away from curbs and other hazards.

Question 6

During a fifth-wheel inspection, should you look into the coupling gap to verify that the jaws are closed around the kingpin shank?

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

The statement is true. Look into the back of the fifth wheel and verify that the locking jaws have closed around the shank, not the head, of the kingpin. Also confirm that there is no gap between the upper and lower fifth-wheel surfaces and that the locking lever and safety latch are secured.
