Sample Delaware CDL Test Questions - General Knowledge

Question 1

What is the safest response when another driver behaves aggressively toward you?

  1. A Maintain eye contact with the driver
  2. B Respond with similar gestures or driving behavior
  3. C Accelerate to prevent the driver from passing
  4. D Avoid reacting and make an effort to get out of the driver’s way

Correct answer: D – Avoid reacting and make an effort to get out of the driver’s way

Make every reasonable effort to get out of an aggressive driver’s way. Do not challenge the driver by speeding up or trying to hold your position, and avoid eye contact or responding to gestures. If it can be done safely, report dangerous behavior to the appropriate authorities.

Question 2

Under which two conditions should a driver downshift before reaching the hazard?

  1. A Before stopping and while leaving a curve
  2. B Before starting and while climbing a hill
  3. C Before shutting off the engine and leaving the cab
  4. D Before descending a hill and before entering a curve

Correct answer: D – Before descending a hill and before entering a curve

Downshift before starting down a hill so the engine can help control speed without excessive brake use. You should also slow and downshift before entering a curve. Shifting in the curve can reduce stability because the drive wheels may lose traction while the clutch is disengaged.

Question 3

Which factors should guide your speed selection on a long, steep downgrade?

  1. A Perception distance, reaction distance, and traffic spacing
  2. B Reaction time, vehicle length, and posted route number
  3. C Vehicle and cargo weight, grade length and steepness, road conditions, and weather
  4. D Vehicle speed, perception time, and total stopping distance only

Correct answer: C – Vehicle and cargo weight, grade length and steepness, road conditions, and weather

A safe downgrade speed must account for the total weight of the vehicle and cargo, the grade’s length and steepness, road conditions, and weather. Observe posted speed limits and maximum-safe-speed signs. Select the proper gear before beginning the descent and use the engine’s braking effect to help control speed.

Question 4

How many numbered hazard classes are used for hazardous materials?

  1. A 3
  2. B 6
  3. C 9
  4. D 12

Correct answer: C – 9

Hazardous materials are organized into nine numbered classes. Several classes are divided further to describe particular hazards, such as flammable gas, poisonous gas, or infectious substances. The class or division identifies the primary transportation hazard presented by the material.

Question 5

What is the purpose of a hazardous-materials placard?

  1. A To display a carrier’s safety slogan
  2. B To mark the vehicle as an oversized load
  3. C To show the vehicle’s registered weight
  4. D To identify the hazard class of cargo carried in the vehicle or bulk package

Correct answer: D – To identify the hazard class of cargo carried in the vehicle or bulk package

A placard is a warning sign displayed on the outside of a vehicle or bulk package. It identifies the hazard class of the cargo so other road users and emergency personnel can recognize the risk. Placards are square-on-point, giving them a diamond-shaped appearance.

Question 6

If another vehicle is following your commercial vehicle too closely, what should you do?

  1. A Brake sharply to warn the other driver
  2. B Activate the four-way flashers and maintain speed
  3. C Increase the following distance ahead of your vehicle
  4. D Wave the other driver around immediately

Correct answer: C – Increase the following distance ahead of your vehicle

Increase the space between your vehicle and the traffic ahead. This added room allows you to slow gradually and reduces the need for abrupt braking or steering. Signal early and make speed changes smoothly when a vehicle is tailgating you.
