Sample New York CDL Test Questions - General Knowledge

Question 1

Whenever possible, how should you position a combination vehicle before backing with a trailer?

  1. A So the trailer can be backed in a straight line
  2. B So the trailer must curve toward the passenger side
  3. C So the mirrors are unnecessary
  4. D In any position that avoids using a pull-up

Correct answer: A – So the trailer can be backed in a straight line

Position the combination vehicle so the trailer can be backed in a straight line whenever possible. Before moving, inspect the backing path and check side and overhead clearances. If a curved path is unavoidable, back toward the driver’s side for better visibility, use both mirrors, move slowly, and correct any drift promptly.

Question 2

Why is backing toward the driver’s side preferred when a turn is necessary?

  1. A Traffic law always requires it
  2. B It eliminates the need to use mirrors
  3. C It gives the driver a better view of the vehicle’s rear path
  4. D It guarantees that no helper will be needed

Correct answer: C – It gives the driver a better view of the vehicle’s rear path

New York’s CDL manual recommends driver-side backing because the driver can see the vehicle’s rear path more clearly. When turning toward that side, the driver can monitor the rear by looking through the side window while also checking the mirrors. Passenger-side backing provides less visibility and should be avoided when a safer driver-side approach is available.

Question 3

When a transport vehicle is required to display hazardous-materials placards, which description is correct?

  1. A Placards are displayed on each side and each end
  2. B Each placard measures at least 250 mm (9.84 inches) on each side
  3. C Placards are diamond-shaped, or square-on-point
  4. D All of the above

Correct answer: D – All of the above

Federal hazardous-materials rules require placards on each side and each end of a transport vehicle when placarding is required. Each diamond-shaped, square-on-point placard must measure at least 250 mm, or 9.84 inches, on each side. All three descriptions in the answer choices are correct.

Question 4

Which action helps protect a crash scene from a second collision?

  1. A Leave your vehicle stopped in a traffic lane
  2. B Stand in the roadway and wave at approaching vehicles
  3. C Call your employer before warning traffic
  4. D Activate the flashers and place reflective triangles where approaching drivers can see them

Correct answer: D – Activate the flashers and place reflective triangles where approaching drivers can see them

The New York CDL manual says the first priority at a crash scene is preventing another crash. If possible, move the involved vehicle to the roadside, turn on the hazard flashers, and set out reflective triangles. The warning devices must be visible early enough for approaching drivers to recognize the danger and respond safely.

Question 5

Which statement about steering and exhaust-system inspection is accurate?

  1. A More than 10 degrees of steering-wheel play can make the vehicle difficult to steer
  2. B An exhaust leak is acceptable when it is outside the cab
  3. C Minor power-steering fluid leaks are normal
  4. D Opening a window makes it safe to drive with a leaking exhaust system

Correct answer: A – More than 10 degrees of steering-wheel play can make the vehicle difficult to steer

The New York CDL manual identifies steering-wheel play exceeding 10 degrees—about two inches at the rim of a 20-inch wheel—as a condition that can make steering difficult. Power-steering components must be checked for leaks. Exhaust leaks are also defects because a damaged system can allow poisonous fumes into the cab or sleeper berth.

Question 6

An orange, diamond-shaped highway warning sign usually identifies:

  1. A A temporary traffic-control or work-zone condition
  2. B A permanent general-warning condition
  3. C A destination or route direction
  4. D A required stop

Correct answer: A – A temporary traffic-control or work-zone condition

Orange warning signs are used in temporary traffic-control zones, including areas affected by construction, maintenance, utility work, or incidents. These signs warn road users about conditions that might not otherwise be apparent. Temporary traffic-control warning signs generally have a black legend and border on an orange background.
