Sample New Jersey CDL Test Questions - General Knowledge

Question 1

What must a driver do when approaching a YIELD sign?

When approaching this sign _______________.
  1. A Stop every time, even when the intersection is clear
  2. B Enter quickly before cross traffic arrives
  3. C Slow to a reasonable speed, stop if necessary, and yield to traffic presenting an immediate hazard
  4. D Continue because intersecting traffic must stop

Correct answer: C – Slow to a reasonable speed, stop if necessary, and yield to traffic presenting an immediate hazard

In New Jersey, a driver approaching a yield sign must slow to a reasonable speed for the existing conditions and visibility. The driver must stop if necessary and yield to intersecting traffic that is close enough to present an immediate hazard. The sign does not automatically require a stop when the way is clear.

  2. B The connections show no excessive corrosion
  3. C The battery box and its cover or door are secure and undamaged
  4. D All of the listed items

Correct answer: D – All of the listed items

The New Jersey CDL vehicle-inspection material requires several battery checks on a coach or transit bus. The batteries must be secure, connections tight, and cell caps present, with no excessive corrosion at the connections. The battery box and its cover or door must also be undamaged and secure.

Question 3

According to the CDL manual, what is the leading cause of injuries and deaths in roadway work zones?

  1. A Speeding traffic
  2. B Wet pavement
  3. C Poorly adjusted brakes
  4. D Reduced daylight

Correct answer: A – Speeding traffic

The New Jersey CDL manual identifies speeding traffic as the leading cause of injury and death in roadway work zones. Drivers should obey posted limits and watch the speedometer so their speed does not gradually increase. Additional speed reduction may be needed for poor road or weather conditions and when workers are near the roadway.

Question 4

An over-the-counter cold medicine warns that it may cause drowsiness. What should a CMV driver do?

  1. A Take half the recommended dose and continue driving
  2. B Do not operate the CMV while the medicine could impair alertness or safe driving
  3. C Use it only while driving during daylight
  4. D Drive if the dispatcher approves its use

Correct answer: B – Do not operate the CMV while the medicine could impair alertness or safe driving

Cold medicines and other over-the-counter drugs can cause drowsiness or otherwise interfere with safe driving. A driver may not operate a CMV when alertness or ability is impaired, or is likely to become impaired, enough to make driving unsafe. Dispatcher approval does not make an impairing medicine safe to use while driving.

Question 5

Which driver actions can cause a vehicle to skid?

  1. A Oversteering
  2. B Overbraking
  3. C Driving too fast for conditions
  4. D All of the above

Correct answer: D – All of the above

A skid occurs when the tires lose traction. Overbraking can lock the wheels, while oversteering demands a sharper turn than the vehicle can make. Driving too fast for conditions can also lead to serious skids and increase the likelihood of overbraking or oversteering.

Question 6

There is not enough room to stop before reaching an obstacle. Which statement about evasive steering is correct?

  1. A A vehicle can almost always be turned around an obstacle more quickly than it can be stopped
  2. B Stopping is always the safest available action
  3. C Leaving the roadway is always more dangerous than a collision
  4. D The driver should release the safety belt before impact

Correct answer: A – A vehicle can almost always be turned around an obstacle more quickly than it can be stopped

When there is not enough distance to stop, steering away from the hazard may be necessary. A vehicle can almost always be turned to miss an obstacle more quickly than it can be brought to a stop. However, abrupt steering can create a rollover risk for top-heavy vehicles and tractors pulling multiple trailers.
