Sample New Mexico Tanker Test Questions

Question 1

A tank vehicle’s high center of gravity generally makes it top-heavy. True or false?

  1. A. True
  2. B. False

Correct answer: A. – True

Much of a tank vehicle’s load is carried high above the road, creating a high center of gravity. This makes the vehicle top-heavy and easier to roll over. The New Mexico CDL manual notes that liquid tankers are especially prone to rollover.

Question 2

When must a tanker inspection be completed?

  1. A. At the weekly service interval
  2. B. Only after unloading
  3. C. Only during refueling stops
  4. D. Before loading, unloading, or driving

Correct answer: D. – Before loading, unloading, or driving

Inspect the tanker before loading, before unloading, and before driving it. This inspection confirms that the vehicle can safely carry the liquid or gas and can be operated safely. Tank vehicles also have special components to check, including valves, hoses, connections, covers, vents, and required equipment.

Question 3

Why does an un-baffled, or smooth-bore, tanker require extra caution?

  1. A. It contains only two baffles
  2. B. Nothing inside slows the liquid’s movement
  3. C. It is divided into sealed compartments by bulkheads
  4. D. Surge occurs only after the vehicle stops

Correct answer: B. – Nothing inside slows the liquid’s movement

A smooth-bore tank is un-baffled, so nothing inside slows the flow of liquid. This allows very strong forward-and-back surge, particularly during starts and stops. The driver must operate slowly and carefully because the moving liquid can strongly affect vehicle handling.

Question 4

What does “outage” mean when loading a cargo tank?

  1. A. The required empty space left for liquid expansion
  2. B. A shortage of the product at the refinery
  3. C. A loss of power to the tank’s monitoring equipment
  4. D. The process of discharging liquid cargo

Correct answer: A. – The required empty space left for liquid expansion

Liquids expand as they warm, so a cargo tank must not be filled completely. The empty space left for this expansion is called outage. Different liquids expand by different amounts, and the driver must know the required outage for the bulk liquid being hauled.

Question 5

On a slippery surface, what can liquid surge do after a tanker has stopped?

  1. A. Push the vehicle forward
  2. B. Make the stop smoother
  3. C. Separate the trailer from the tractor
  4. D. Shorten the vehicle’s stopping distance

Correct answer: A. – Push the vehicle forward

Liquid in a partially filled tank moves back and forth as the vehicle stops. When the wave reaches the end of the tank, it can push the vehicle in the direction the wave is moving. On ice or another slippery surface, New Mexico’s CDL manual warns that this force can shove a stopped truck into an intersection.

Question 6

Which statement about making a rapid steering maneuver in a tank vehicle is correct?

  1. A. Brake hard while making the steering movement
  2. B. A tank vehicle’s low center of gravity prevents rollover
  3. C. Oversteering is unlikely to affect traction
  4. D. Avoid braking while making the rapid steering movement

Correct answer: D. – Avoid braking while making the rapid steering movement

A tank vehicle may roll over if the driver steers quickly while braking. If a quick stop is required, use controlled or stab braking as directed, but avoid adding a rapid steering movement while braking. Combining those actions creates the rollover danger tested here.
