Sample Hawaii CDL Test Questions - General Knowledge

Question 1

Which action is part of monitoring a commercial vehicle while driving?

  1. A Watch only for pedestrians
  2. B Open the hood to check the brake fluid
  3. C Monitor gauges and instruments for signs of trouble
  4. D Leave the turn signals operating continuously

Correct answer: C – Monitor gauges and instruments for signs of trouble

During a trip, regularly monitor the vehicle's instruments, including air-pressure, temperature, pressure, and electrical gauges. Also check the mirrors and remain alert for anything unusual that you see, hear, smell, or feel. If a warning or other sign of trouble appears, investigate it from a safe location rather than continuing without checking.

Question 2

Which statement describes a safe practice when backing a heavy vehicle?

  1. A Remain in the cab instead of getting out to check the path
  2. B Avoid backing when a forward-moving alternative is available
  3. C Have a helper shout directions from anywhere behind the vehicle
  4. D Back toward the passenger side whenever possible

Correct answer: B – Avoid backing when a forward-moving alternative is available

Backing is dangerous because the driver cannot see everything behind the vehicle. Avoid it whenever practical, and park in a position that permits a forward departure. When backing is necessary, start from the proper position, check the path, back toward the driver's side when possible, and use a helper who gives clear signals from a visible location.

Question 3

A CMV is stopped on the shoulder of a divided highway in Hawaii. Where should its three warning devices be placed?

  1. A 50 feet, 50 feet, and 50 feet from the vehicle
  2. B 100 feet, 50 feet, and 50 feet from the vehicle
  3. C Within 10 feet, then 100 feet and 200 feet toward approaching traffic
  4. D 100 feet ahead, 100 feet behind, and 10 feet beside the vehicle

Correct answer: C – Within 10 feet, then 100 feet and 200 feet toward approaching traffic

On a divided or one-way highway, place one device on the traffic side within 10 feet of the rear of the stopped CMV. Place the other two 100 feet and 200 feet toward approaching traffic, in the center of the occupied lane or shoulder. These devices generally must be placed as soon as possible and within ten minutes.

Question 4

How far ahead should a commercial driver generally scan?

  1. A 1 to 2 seconds
  2. B 5 to 8 seconds
  3. C 12 to 15 seconds
  4. D 18 to 21 seconds

Correct answer: C – 12 to 15 seconds

Good drivers look at least 12 to 15 seconds ahead while continuing to shift their attention between near and distant conditions. At lower speeds, that is approximately one city block. At highway speeds, it is about one-quarter mile. Looking well ahead provides more time to adjust speed, change lanes safely, or respond to developing hazards.

Question 5

What does a yellow diamond warning sign displaying a truck indicate?

This sign warns drivers to _____________.
  1. A A railroad crossing used only by freight trains
  2. B A route reserved exclusively for trucks
  3. C Passenger vehicles must remain in the left lane
  4. D Trucks may be entering or crossing the highway

Correct answer: D – Trucks may be entering or crossing the highway

This warning sign alerts drivers that trucks may enter or cross the highway ahead. Reduce speed as conditions require and watch for large vehicles entering the traffic stream. Hawaii's driver manual explains that warning signs identify dangers that exist or may be found on or near the road and require drivers to be prepared to take safe action.

Question 6

In defensive-driving terms, what is a hazard?

  1. A Any road condition or road user that presents a possible danger
  2. B Only a solid object lying in the travel lane
  3. C Only something that completely blocks the roadway
  4. D An event determined entirely by chance

Correct answer: A – Any road condition or road user that presents a possible danger

A hazard is any roadway condition or road user—such as a driver, bicyclist, or pedestrian—that presents a possible danger. A hazard does not have to be blocking the road or creating an immediate emergency. Recognizing it early gives the driver more time to slow down, check surrounding traffic, or take another safe action.
