Sample New York Combination Test Questions

Question 1

Combination vehicles generally require more driving knowledge and skill than single commercial vehicles.

  1. A True
  2. B False

Correct answer: A – True

New York’s CDL manual explains that combination vehicles are usually heavier and longer than single commercial vehicles and require more driving skill. Drivers must manage concerns such as rollover risk, offtracking, trailer skids, coupling, and the additional parts of the trailer brake system. These factors require specialized knowledge and control.

Question 2

Why must wheel chocks be used when parking a trailer that has no spring brakes?

  1. A The trailer will always roll when parked on level ground
  2. B Stored air can leak away until the trailer has no braking force
  3. C The chocks maintain pressure in the service line
  4. D The chocks keep the tractor protection valve open

Correct answer: B – Stored air can leak away until the trailer has no braking force

A trailer without spring brakes uses stored air to apply its emergency brakes and does not have a separate parking brake. If the stored air leaks away, the brakes eventually release and the trailer wheels can turn freely. New York’s CDL manual instructs drivers to use wheel chocks to keep such a trailer from moving.

Question 3

Why should the trailer hand valve not be used for routine braking while driving?

  1. A It applies the tractor brakes too slowly
  2. B It automatically sets the parking brakes
  3. C It cannot operate when the trailer is loaded
  4. D It can cause the trailer wheels to skid

Correct answer: D – It can cause the trailer wheels to skid

The trailer hand valve applies the trailer brakes without applying the tractor brakes. Using it during normal driving can lock the trailer wheels and cause a trailer skid or jackknife. It should be used only to test the trailer brakes; routine braking should be performed with the foot brake, which applies the brakes at all wheels.

Question 4

After coupling a tractor and semitrailer, the locking jaws should encircle which section of the kingpin?

  1. A The shank
  2. B The head
  3. C The base
  4. D Any of these sections

Correct answer: A – The shank

The fifth-wheel locking jaws must close around the shank of the kingpin, not its head. Jaws closed around the head may indicate that the trailer was too high during coupling. Verify the jaw position, locking lever, and safety latch before operating the combination.

Question 5

In a crash, a fully loaded rig is about ten times more likely to roll over than an empty rig.

  1. A True
  2. B False

Correct answer: A – True

New York’s CDL manual states that fully loaded rigs are ten times more likely to roll over in a crash than empty rigs. Cargo piled high raises the center of gravity and makes the vehicle easier to overturn. Keep cargo low and centered, and reduce speed before entering turns.

Question 6

Why should cargo be positioned as close to the ground as practical?

  1. A It lowers the center of gravity and reduces rollover risk
  2. B It makes every type of cargo easier to unload
  3. C It eliminates the need for cargo securement
  4. D It prevents all trailer-wheel skids

Correct answer: A – It lowers the center of gravity and reduces rollover risk

Cargo loaded high raises the vehicle’s center of gravity, making it easier to tip over in a curve or sudden maneuver. Keeping the cargo low reduces rollover risk and is especially important in combination vehicles. The load should also be centered and distributed as evenly as possible.
