  2. B. Abnormal wear or tread separation
  3. C. Cuts or other tire damage
  4. D. All of the above

Correct answer: D. – All of the above

Question 2

Which vehicle fire may require large quantities of water for cooling?

  1. A. A burning tire
  2. B. A gasoline fire
  3. C. A diesel-fuel fire
  4. D. An electrical fire

Correct answer: A. – A burning tire

A burning tire must be cooled, and a large amount of water may be necessary. Water can also be used on ordinary materials such as wood, paper, or cloth. It should not be used on an electrical fire because of shock risk or on a gasoline fire because it can spread the flames.

Question 3

When should you select a lower gear for a curve?

  1. A. Before entering the curve
  2. B. After beginning the turn
  3. C. At the sharpest point of the curve
  4. D. Immediately after leaving the curve

Correct answer: A. – Before entering the curve

Reduce to a safe speed and select the proper lower gear before entering the curve. This allows some power to be used through the curve, helping the vehicle remain stable while turning. Shifting in the curve can distract the driver and interfere with smooth vehicle control.

Question 4

During the air-pressure buildup test for a dual air system, what increase should normally occur within 45 seconds?

  1. A. From 85 to 100 psi
  2. B. From 40 to 60 psi
  3. C. From 60 to 80 psi
  4. D. From 100 to 120 psi

Correct answer: A. – From 85 to 100 psi

The Virginia CDL manual specifies that a dual air system should normally build from 85 to 100 psi within 45 seconds while the engine is at operating rpm. This measures the buildup rate rather than the system’s maximum pressure. Vehicles with larger-than-minimum air tanks may take longer, so the manufacturer’s specifications must also be checked.

Question 5

Which actions are appropriate when assisting an injured person at a crash scene?

  1. A. Move a severely injured person only when fire or traffic creates danger
  2. B. Control heavy bleeding with direct pressure
  3. C. Keep the injured person warm
  4. D. All of the above

Correct answer: D. – All of the above

Do not move a severely injured person unless fire or passing traffic makes movement necessary. Heavy bleeding may be controlled by applying direct pressure to the wound, and the person should be kept warm. If a qualified responder is already providing care, stay out of the way unless asked to assist.

Question 6

What should you do immediately after stopping a commercial vehicle on the roadside at night?

  1. A. Turn on the four-way emergency flashers
  2. B. Wait 15 minutes before placing warning devices
  3. C. Leave the left turn signal operating
  4. D. Leave the high-beam headlights on

Correct answer: A. – Turn on the four-way emergency flashers

Turn on the four-way emergency flashers when a commercial vehicle is stopped on a road or shoulder, especially at night. Federal regulations require the hazard warning system to be activated immediately and kept operating until the external warning devices are placed. The Virginia CDL manual states that those warning devices must be set out within 10 minutes.
