Sample New York CDL Test Questions - General Knowledge

Question 1

What is the general brake-pedal technique when operating a commercial vehicle with working ABS?

  1. A Always use less pedal pressure than with conventional brakes
  2. B Brake normally, using only the force needed to stop safely and maintain control
  3. C Pump the brake pedal rapidly whenever ABS activates
  4. D Release the accelerator and wait for ABS to apply the brakes

Correct answer: B – Brake normally, using only the force needed to stop safely and maintain control

With ABS, use the brakes as you normally would and apply only the braking force needed to stop safely while maintaining control. Monitor the vehicle as it slows and reduce pressure if safely necessary to regain control. During an emergency stop, a straight truck or combination vehicle with working ABS on every axle may be braked with a full application.

Question 2

Driving a commercial motor vehicle while under the influence of a drug that makes you unable to drive safely is:

  1. A Allowed whenever the drug was prescribed
  2. B Prohibited
  3. C Allowed for diet pills and cold medicines
  4. D Acceptable if only a small amount of alcohol is also consumed

Correct answer: B – Prohibited

Federal on-duty rules prohibit a driver from using or being under the influence of specified drugs or any other substance to a degree that makes the driver incapable of safely operating a motor vehicle. For covered prescribed substances, the exception applies only when a licensed medical practitioner has advised that the substance will not affect safe operation. Alcohol can intensify the effects of other drugs.

Question 3

Which listed item is a suspension-system component?

  1. A Tie rod
  2. B Drag link
  3. C Pitman arm
  4. D None of these

Correct answer: D – None of these

The tie rod, drag link, and pitman arm are identified as parts of the steering system. Suspension components include items such as springs, spring hangers, torque rods, shock absorbers, and air-suspension parts. None of the three listed steering-linkage components is a suspension part.

Question 4

What is perception distance?

  1. A The distance traveled while moving your foot from the accelerator to the brake pedal
  2. B The distance traveled from seeing a hazard until your brain recognizes it
  3. C The distance traveled after the brakes are applied
  4. D The complete distance required to recognize a hazard and stop

Correct answer: B – The distance traveled from seeing a hazard until your brain recognizes it

Perception distance begins when the driver’s eyes see a hazard and ends when the brain recognizes it. Reaction distance follows while the driver responds and physically applies the brakes. Braking distance is then traveled while the brakes slow the vehicle; these three distances make up total stopping distance.

Question 5

A tank vehicle may carry liquids or gases even when the tank is leaking.

  1. A True
  2. B False

Correct answer: B – False

New York’s official CDL manual directs drivers not to carry liquids or gases in a leaking tank. Before loading, unloading, or driving, inspect beneath and around the vehicle for signs of leakage. The tank shell, valves, pipes, connections, hoses, manhole covers, and vents are among the components that must be checked.

Question 6

When speed doubles, the braking distance under comparable conditions becomes about how many times longer?

  1. A Three times
  2. B Two times
  3. C Four times
  4. D Five times

Correct answer: C – Four times

Doubling speed makes the vehicle’s braking distance approximately four times longer under comparable conditions. For example, increasing speed from 20 mph to 40 mph quadruples both braking distance and impact force. This four-times relationship concerns braking distance; total stopping distance also includes the distance traveled during perception and reaction.
