Sample Delaware CDL Test Questions - General Knowledge

Question 1

What term describes the rear wheels following a more inward path than the front wheels during a turn?

  1. A Jackknifing
  2. B Sidetracking
  3. C Off-tracking
  4. D Fishtailing

Correct answer: C – Off-tracking

Off-tracking occurs because the rear wheels follow a different path from the front wheels during a turn. The rear wheels track farther toward the inside of the corner, and longer vehicles off-track more. Drivers must allow enough turning room to keep the rear wheels away from curbs, pedestrians, and other objects.

Question 2

Which preparation helps prevent distracted driving?

  1. A Eat a heavy meal immediately before driving
  2. B Depend on large amounts of coffee
  3. C Learn the vehicle’s features and adjust controls before moving
  4. D Keep a phone ready for reading messages while driving

Correct answer: C – Learn the vehicle’s features and adjust controls before moving

The Delaware manual recommends eliminating in-vehicle distractions before driving. Learn the vehicle’s equipment, adjust the mirrors and controls, program the radio or navigation system, and secure loose objects before moving. Do not read or type messages while driving, and avoid activities such as eating that take attention away from the road.

Question 3

When backing with a trailer, position the combination to back:

  1. A In a straight line whenever possible
  2. B Toward the passenger side whenever possible
  3. C Without using the outside mirrors
  4. D Along any path that requires the fewest pull-ups

Correct answer: A – In a straight line whenever possible

Whenever possible, arrange the vehicle so the trailer can be backed in a straight line. Straight backing reduces the steering corrections needed and makes the trailer easier to control. If a curved path is unavoidable, back toward the driver’s side for better visibility and use both mirrors frequently.

Question 4

Which type of fire may require large amounts of water for cooling?

  1. A A tire fire
  2. B A gasoline fire
  3. C An electrical fire
  4. D An unidentified chemical fire

Correct answer: A – A tire fire

A burning tire must be cooled, and substantial amounts of water may be needed. Water must not be used on an electrical fire because of shock danger or on a gasoline fire because it can spread the burning fuel. Drivers should know the proper extinguisher and firefighting method before an emergency occurs.

Question 5

Which list best identifies items to monitor or inspect while a trip is underway?

  1. A Gauges, exhaust, lights, cargo securement, and coupling devices
  2. B Gauges, brakes, lights, pumps, and hoses
  3. C Gauges, brakes, lights, cargo securement, and coupling devices
  4. D Gauges, shock absorbers, brake shoes, and frame members

Correct answer: C – Gauges, brakes, lights, cargo securement, and coupling devices

Watch the gauges and use your senses to detect trouble throughout the trip. When you stop, inspect critical items such as brakes, lights and reflectors, cargo securement, and trailer coupling devices. Tires, wheels, rims, and trailer brake and electrical connections should also be checked.

Question 6

When using a helper while backing, which hand signal is most important to agree on beforehand?

  1. A Stop
  2. B Continue backing
  3. C Turn left
  4. D Turn right

Correct answer: A – Stop

Before backing, establish hand signals that both you and the helper understand. The Delaware manual specifically emphasizes agreeing on a stop signal. The helper should remain near the rear of the vehicle in a position where you can see them.
