Sample New Jersey CDL Test Questions - General Knowledge

Question 1

What does a Signal Ahead (W3-3) warning sign tell a driver?

This sign indicates that the driver is ___________.
  1. A A yield sign is ahead
  2. B A stop sign is ahead
  3. C A traffic-control signal is ahead
  4. D A railroad crossing is ahead

Correct answer: C – A traffic-control signal is ahead

The Signal Ahead sign warns drivers that they are approaching a traffic-control signal. It is particularly important where the primary signal is not visible from far enough away for drivers to respond safely. A commercial driver should be prepared to adjust speed and stop if the upcoming signal requires it.

Question 2

A Reverse Turn sign showing a right turn followed by a left turn warns of:

This sign warns drivers to _____________.
  1. A Two gradual curves, first right and then left
  2. B One right turn
  3. C One left turn
  4. D Two successive turns, first right and then left

Correct answer: D – Two successive turns, first right and then left

A Reverse Turn sign warns of two roadway turns in opposite directions separated by a relatively short distance. When the symbol bends right first and then left, the driver will encounter the right turn first. The sign allows the driver to reduce speed as needed before entering the sequence of turns.

Question 3

During a vehicle inspection, what condition should you look for at wheel bearing seals?

  1. A Excessive tightness
  2. B Leakage
  3. C Low brake-fluid level
  4. D Incorrect safety markings

Correct answer: B – Leakage

Wheel bearing seals should be checked for signs of leakage during the vehicle inspection. A leaking seal can allow lubricant to escape from the wheel bearing area. The driver should examine the wheel and hub area for visible wetness or other evidence of a leak.

Question 4

How should you control your speed when driving at night?

  1. A Depend on caffeine if you become sleepy
  2. B Drive faster to shorten the trip
  3. C Rely on fresh air from an open window to remain alert
  4. D Drive slowly enough to stop within the distance illuminated by your headlights

Correct answer: D – Drive slowly enough to stop within the distance illuminated by your headlights

At night, adjust your speed so that your stopping distance remains within your sight distance. You must be able to stop within the area illuminated by your headlights; otherwise, a hazard may become visible too late. If you become sleepy, stop at the nearest safe place because sleep is the only safe cure for fatigue.

Question 5

Over-the-counter cold medicine can make a commercial driver drowsy.

  1. A True
  2. B False

Correct answer: A – True

Some prescription and over-the-counter cold medicines can cause drowsiness or otherwise reduce safe driving ability. The New Jersey CDL manual advises drivers to pay attention to medication warning labels and their doctor's instructions. A driver should determine a medicine's possible effects before operating a commercial vehicle.

Question 6

What should you do when another vehicle is following your commercial vehicle too closely?

  1. A Increase the following distance ahead of you
  2. B Flash your brake lights repeatedly
  3. C Accelerate to create distance behind you
  4. D Signal that the other driver should pass

Correct answer: A – Increase the following distance ahead of you

Increase the space between your vehicle and the traffic ahead. This extra room reduces the likelihood that you will need to make a sudden speed or direction change. Avoid speeding up or flashing your brake lights at the tailgater; the New Jersey CDL manual recommends gradual, predictable driving instead.
