Sample West Virginia Tanker Test Questions

Question 1

Which tank condition is the primary source of liquid surge?

  1. A Worn suspension components
  2. B A load carried high above the roadway
  3. C A tank that is only partly filled with liquid
  4. D A tank that has been completely drained

Correct answer: C – A tank that is only partly filled with liquid

Liquid surge develops when cargo moves inside a partially filled tank. During acceleration, braking, or stopping, the liquid shifts and may push the vehicle in the direction of the wave. A high center of gravity is a separate handling concern; surge is produced by liquid that has room to move.

Question 2

When inspecting a tank vehicle equipped with an emergency shut-off system, which condition must be verified?

  1. A The system is painted a standard color
  2. B The controls are mounted on the driver’s side
  3. C The label is visible from inside the cab
  4. D The system operates properly

Correct answer: D – The system operates properly

The tank-vehicle inspection includes any installed special-purpose equipment. Emergency shut-off systems are specifically listed among the items that must work. Appearance, control location, or label visibility does not demonstrate operability; the driver must verify that the system functions properly.

Question 3

A high center of gravity creates which major handling risk for a tank vehicle?

  1. A Reduced traction only when the tank is empty
  2. B Greater stability during sudden turns
  3. C The ability to take curves at higher speeds
  4. D An increased chance of rolling over

Correct answer: D – An increased chance of rolling over

A tank vehicle carries much of its load high above the roadway, making it top-heavy. The West Virginia CDL manual warns that liquid tankers are especially easy to roll over and may overturn even at posted curve speeds. Drivers should take highway curves and ramps well below the posted speeds.

Question 4

If leaking cargo causes a spill, which statement about cleanup costs is accurate?

  1. A The driver may be held liable for cleanup
  2. B The driver can never be liable for cleanup
  3. C The driver is automatically liable in every case
  4. D The shipper alone must always pay for cleanup

Correct answer: A – The driver may be held liable for cleanup

The West Virginia CDL manual warns that operating a leaking tank can lead to a citation, being prevented from driving farther, and possible liability for spill cleanup. Cleanup liability is described as possible rather than automatic in every incident. Thus, the driver may be held financially responsible.

Question 5

When a tanker driver must make a quick steering maneuver, which technique is correct?

  1. A Brake hard throughout the turn
  2. B Turn farther than necessary and hold the wheel
  3. C Accelerate sharply while turning
  4. D Avoid applying the brakes while turning

Correct answer: D – Avoid applying the brakes while turning

During a quick steering maneuver, braking can lock the wheels and cause a skid. Tank vehicles add a rollover risk because they are top-heavy, and steering quickly while braking may cause a rollover. Turn only as much as necessary to clear the hazard and be prepared to counter-steer.

Question 6

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

  1. A Gasoline
  2. B Food-grade liquids such as milk
  3. C Gravel and other construction aggregate
  4. D Palletized freight

Correct answer: B – Food-grade liquids such as milk

Smooth-bore tanks have no baffles to slow the liquid’s movement. They are usually used to transport food products such as milk because baffles make the tank interior difficult to clean under sanitation requirements. The lack of baffles also creates strong forward-and-back surge, requiring extra caution during starts and stops.
