Sample Virginia Tanker Test Questions

Question 1

Which driver actions can cause a tank vehicle to skid?

  1. A. Accelerating too aggressively
  2. B. Applying too much braking force
  3. C. Making excessive steering movements
  4. D. All of the above

Correct answer: D. – All of the above

Over-acceleration, over-braking, and over-steering can each cause a tank vehicle to skid. Tank vehicles are especially sensitive to sudden control inputs because of their high center of gravity and shifting cargo. Smooth steering, acceleration, and braking help preserve traction and vehicle stability.

Question 2

When bringing a tank vehicle to a stop, maintain steady brake pressure and:

  1. A. Release the brakes immediately before stopping
  2. B. Avoid releasing the brakes too soon
  3. C. Pump the brakes throughout every stop
  4. D. Apply the brakes abruptly near the stopping point

Correct answer: B. – Avoid releasing the brakes too soon

Steady braking helps manage the forward-and-back movement of liquid cargo. Releasing the brakes too soon can allow surge to push the vehicle as it reaches the stopping point. Begin braking well in advance and allow additional following distance when operating a tank vehicle.

Question 3

A tank vehicle endorsement can be required only for Class A and Class B commercial vehicles.

  1. A. True
  2. B. False

Correct answer: B. – False

This statement is false. Virginia’s official CDL manual explains that the tank endorsement applies to Class A, B, and qualifying Class C vehicles; for Class C, it applies when hazardous materials are transported in tanks meeting the capacity thresholds. Federal CDL rules define Group C hazardous-material vehicles as CMVs and require an endorsement to operate a tank vehicle.

Question 4

Unbaffled liquid tanks are commonly used to transport:

  1. A. Gasoline
  2. B. Food products such as milk
  3. C. Industrial acids
  4. D. Dense construction aggregates

Correct answer: B. – Food products such as milk

Unbaffled tanks, also called smooth-bore tanks, are commonly used for food products such as milk. Their smooth interiors are easier to clean for sanitation purposes. Because there are no baffles to slow the liquid, forward-and-back surge is strong, requiring extra care during starts and stops.

Question 5

Which cargo is most commonly associated with a smooth-bore tank?

  1. A. Gasoline
  2. B. Milk or another liquid food product
  3. C. Packaged chemicals
  4. D. Dry construction materials

Correct answer: B. – Milk or another liquid food product

A smooth-bore tank has no internal baffles and is commonly used for liquid food products such as milk. The smooth interior supports thorough cleaning, but it does not control liquid movement. Drivers must account for strong forward-and-back surge, particularly when accelerating or braking.

Question 6

Transporting liquid or gas in a tank that is leaking is:

  1. A. Allowed when the leak is minor
  2. B. Permitted only when the cargo is not hazardous
  3. C. Prohibited regardless of the remaining travel distance
  4. D. Acceptable when the destination is nearby

Correct answer: C. – Prohibited regardless of the remaining travel distance

Virginia’s official CDL manual states that liquids or gases must not be carried in a leaking tank and describes doing so as a crime. A driver may be cited and prevented from continuing, and may also be responsible for spill cleanup. Inspect the tank body, valves, pipes, connections, hoses, covers, and vents for leakage before operating.
