Sample Massachusetts Tanker Test Questions

Question 1

When a tank vehicle is equipped with grounding and bonding cables, what hazard are properly working cables intended to control during applicable flammable-liquid transfers?

  1. A Incorrect navigation readings
  2. B Excessive fuel consumption
  3. C Static discharge that could ignite vapors
  4. D Failure of the tank supports

Correct answer: C – Static discharge that could ignite vapors

The Massachusetts CDL manual says equipped grounding and bonding cables must work. Federal hazardous-materials rules require electrical bonding or grounding during specified Class 3 transfers to control possible static charges and guard against vapor ignition from static discharge. For open-hole cargo-tank loading, the electrical connection must be established before opening the filling hole and remain until it is closed.

Question 2

Why does operating a liquid tank vehicle require additional handling skill?

  1. A The load has a high center of gravity and the liquid can surge
  2. B The load has a low center of gravity and the liquid can surge
  3. C The tank shell is reinforced and usually has extra axles
  4. D The unloading method changes with each product

Correct answer: A – The load has a high center of gravity and the liquid can surge

A tank vehicle is top-heavy because much of the load’s weight is carried high above the road, increasing rollover risk. Liquid in a partially filled tank can also surge, affecting handling during acceleration, braking, and stopping. These two characteristics—not merely the tank’s construction or the product carried—require special driving skill.

Question 3

In bulk-liquid hauling, what does “outage” mean?

  1. A The empty space left in a cargo tank for liquid expansion
  2. B A temporary shortage of a product at a refinery
  3. C A loss of power to the tank’s monitoring equipment
  4. D The procedure used to drain liquid cargo

Correct answer: A – The empty space left in a cargo tank for liquid expansion

A cargo tank should not be loaded completely full because liquid expands as it warms. The unfilled space reserved for that expansion is called outage. Required outage differs by liquid because products expand by different amounts, so the proper requirement for the cargo must be known before loading.

Question 4

A Class A or B CMV carries attached tanks, each rated over 119 gallons. At what minimum combined rated capacity is a tank endorsement required?

  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 classify such a CMV as a tank vehicle when the tanks are designed to transport liquid or gas, each has a rated capacity over 119 gallons, and their aggregate rated capacity is 1,000 gallons or more. Permanent or temporary attachment counts. Operating that tank vehicle requires a tank vehicle endorsement.

Question 5

What must you verify about the intake, discharge, and cut-off valves before loading, unloading, or moving a tank vehicle?

  1. A Every valve is fully open
  2. B Every valve is fully closed
  3. C The outside of each valve is clean
  4. D Each valve is set correctly for the planned operation

Correct answer: D – Each valve is set correctly for the planned operation

The Massachusetts CDL manual directs the driver to inspect the intake, discharge, and cut-off valves and confirm that each is in the correct position before loading, unloading, or moving the vehicle. The proper position depends on the operation. During travel, valves and manhole covers must not be left open.

Question 6

After parking safely and notifying emergency services, what must you do before attempting to extinguish a tank-vehicle fire?

  1. A Open a manhole to release pressure
  2. B Keep the fire from spreading to other combustible material
  3. C Move closer to determine the exact source
  4. D Wait for a mechanic before taking further action

Correct answer: B – Keep the fire from spreading to other combustible material

Before attempting to extinguish a vehicle fire, take steps to keep it from spreading. The vehicle should be parked in an open area away from buildings, vegetation, other vehicles, and anything else that could ignite. If you are unsure which extinguisher to use, especially with hazardous materials, wait for firefighters rather than making the fire worse.
