Sample West Virginia Tanker Test Questions

Question 1

When loading or unloading compartments separated by bulkheads, what must you monitor carefully?

  1. A Tire pressure only
  2. B The outage in every empty compartment
  3. C Weight distribution
  4. D The height of the tank’s centerline

Correct answer: C – Weight distribution

Bulkheads can divide a liquid tank into several smaller compartments. When loading or unloading those compartments, the driver must pay attention to weight distribution. Placing too much weight toward either the front or rear can produce an improperly balanced vehicle, even when the total load remains within its weight limit.

Question 2

What divides some liquid tanks into separate, smaller compartments?

  1. A Baffles
  2. B Smooth-bore walls
  3. C Bulkheads
  4. D Surge plates

Correct answer: C – Bulkheads

Some liquid tanks are divided into several smaller tanks by bulkheads. Baffled tanks also contain internal bulkheads, but those bulkheads have holes that allow liquid to flow through and help control forward-and-back surge. A smooth-bore tank has no internal structure to slow the liquid’s movement.

Question 3

Why does transporting liquid in a tank vehicle require special driving skills?

  1. A The vehicle has a high center of gravity, and the liquid can move
  2. B The vehicle has a low center of gravity, and the liquid remains fixed
  3. C All tank trailers use the same specialized design
  4. D Only hazardous liquids affect vehicle handling

Correct answer: A – The vehicle has a high center of gravity, and the liquid can move

The West Virginia CDL manual identifies a high center of gravity and liquid movement as the main handling concerns. A high center of gravity makes a tank vehicle top-heavy and more susceptible to rollover. Liquid surge in a partially filled tank can also push the vehicle and adversely affect handling during starts, stops, turns, and lane changes.

Question 4

When must a tank vehicle driver know the cargo’s required outage?

  1. A Only after unloading the tank
  2. B Only when using an un-baffled tank
  3. C When hauling liquids in bulk
  4. D Only when the tank is completely empty

Correct answer: C – When hauling liquids in bulk

A cargo tank should not be filled completely because liquids expand as they warm. The unfilled space left for this expansion is called outage. Different liquids expand by different amounts, making their required outage amounts different; the driver must know the applicable requirement whenever hauling liquids in bulk.

Question 5

For the tank vehicle endorsement, temporarily attached portable tanks must have a combined rated capacity of at least how many gallons, with each tank over 119 gallons?

  1. A 100 gallons
  2. B 250 gallons
  3. C 500 gallons
  4. D 1,000 gallons

Correct answer: D – 1,000 gallons

Federal CDL rules define a tank vehicle using two capacity thresholds: each counted tank must have a rated capacity greater than 119 gallons, and their aggregate rated capacity must be at least 1,000 gallons. The tanks may be permanently or temporarily attached to the vehicle or chassis. The West Virginia CDL manual uses these same thresholds for the tank vehicle endorsement.

Question 6

During a tank vehicle inspection, where should you look for signs of leakage?

  1. A Only inside the cab
  2. B Only directly beneath the tank
  3. C Only on top of the tank
  4. D Under and around the entire vehicle

Correct answer: D – Under and around the entire vehicle

Checking for leaks is a critical part of inspecting any tank vehicle. The driver should look under and around the entire vehicle for evidence of escaping liquid or gas. The inspection should also cover the tank shell, valves, pipes, connections, hoses, manhole covers, and vents because leakage can originate from any of these components.
