Sample Massachusetts Tanker Test Questions

Question 1

What results from carrying much of a tank vehicle’s load high above the roadway?

  1. A The vehicle becomes top-heavy
  2. B The vehicle has a high center of gravity
  3. C The vehicle becomes easier to roll over
  4. D All three statements are correct

Correct answer: D – All three statements are correct

The Massachusetts CDL manual explains that weight carried high above the roadway creates a high center of gravity. This makes the tank vehicle top-heavy and more susceptible to rollover. Liquid tankers can roll over even at posted curve speeds, making reduced speed and smooth steering especially important.

Question 2

What financial consequence may follow a spill from a leaking tank vehicle?

  1. A The operator may be liable for cleanup costs
  2. B The operator can never be charged for cleanup
  3. C The operator is automatically liable in every spill
  4. D Only the shipper can have cleanup responsibilities

Correct answer: A – The operator may be liable for cleanup costs

A driver must not transport liquids or gases in a leaking tank. The CDL manual warns that doing so is a crime and that the operator may also be liable for cleaning up a spill. Because liability depends on the circumstances, it is inaccurate to say that the driver is always liable or can never be liable.

Question 3

Which braking method should be used when a tank vehicle must stop quickly to avoid a crash?

  1. A Abrupt, uncontrolled braking
  2. B Engine braking by itself
  3. C Repeatedly pumping the brake pedal
  4. D Controlled or stab braking

Correct answer: D – Controlled or stab braking

For a quick stop needed to avoid a crash, the tank-vehicle guidance specifies controlled or stab braking. The driver must also avoid steering sharply while braking because a tank vehicle may roll over. During ordinary driving, braking should begin well in advance and be applied smoothly to help control liquid surge.

Question 4

What can liquid surge do when a tank vehicle stops on a slippery surface?

  1. A Push the stopped vehicle forward into an intersection
  2. B Make the vehicle stop more smoothly
  3. C Automatically disconnect a tank trailer
  4. D Shorten the vehicle’s required stopping distance

Correct answer: A – Push the stopped vehicle forward into an intersection

As a tank vehicle stops, liquid in a partially filled tank may continue moving back and forth. When the wave strikes the end of the tank, it pushes the vehicle in the direction the liquid is moving. The Massachusetts CDL manual warns that on ice or another slippery surface, this surge can move a stopped truck into an intersection.

Question 5

How does a high center of gravity affect a tank vehicle?

  1. A It improves the vehicle’s stability
  2. B It prevents the load from shifting
  3. C It permits higher speeds through curves
  4. D It increases the likelihood of a rollover

Correct answer: D – It increases the likelihood of a rollover

A high center of gravity makes a tank vehicle top-heavy and easier to roll over. Tankers may overturn at speeds that other vehicles can safely maintain through a curve. Drivers should enter highway curves and entrance or exit ramps well below the posted speed when necessary for stability.

Question 6

Which statement correctly distinguishes baffles from ordinary tank bulkheads?

  1. A The two terms always describe identical structures
  2. B Baffles form sealed compartments, while bulkheads contain openings
  3. C Baffles are bulkheads with holes that allow liquid to flow through
  4. D Baffles eliminate side-to-side surge, while bulkheads increase it

Correct answer: C – Baffles are bulkheads with holes that allow liquid to flow through

Bulkheads can divide a tank into separate smaller compartments. In a baffled tank, the bulkheads have holes that allow liquid to flow through them. The baffles reduce forward-and-back surge, but side-to-side surge can still occur and contribute to a rollover.
