Sample Tennessee 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 has a greater rollover risk
  4. D. All of the above

Correct answer: D. – All of the above

Tank vehicles carry much of the load’s weight high above the roadway, creating a high center of gravity. This condition makes the vehicle top-heavy and more likely to roll over, particularly when taking curves. Each of the first three choices describes the same stability hazard, making “all of the above” correct.

Question 2

During a tank vehicle inspection, what must you verify about its emergency shut-off system?

  1. A. It is painted red
  2. B. It is within reach of the driver’s seat
  3. C. It has a clearly printed label
  4. D. It operates properly

Correct answer: D. – It operates properly

During the pre-trip inspection, the emergency shut-off system must be checked for proper operation. The Tennessee manual lists it among the special-purpose equipment that must work before the tank vehicle is used. Color, location, or labeling does not replace the required functional check.

Question 3

A Class A or B CMV carries liquid in portable tanks temporarily attached to the vehicle. Each tank is rated above 119 gallons. At what combined rated capacity is an N 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

Under 49 CFR, each qualifying tank must have a rated capacity greater than 119 gallons, and the tanks must have an aggregate rated capacity of at least 1,000 gallons. The tanks may be permanently or temporarily attached to the vehicle or chassis. Operating a qualifying tank vehicle requires an N endorsement.

Question 4

Which description identifies a smooth bore tank?

  1. A. A tank divided into separate compartments
  2. B. A tank fitted with internal baffles
  3. C. A tank without baffles
  4. D. A tank fitted with special insulation

Correct answer: C. – A tank without baffles

A smooth bore tank is an un-baffled liquid tank. Because it has no internal baffles to slow the liquid, forward-and-back surge can be very strong during starts and stops. This handling characteristic requires especially slow and careful acceleration and braking. Compartments and insulation do not define a smooth bore tank.

Question 5

What is the rule if an inspection reveals that a tank is leaking before liquid or gas is transported?

  1. A. A small leak is acceptable
  2. B. Only non-hazardous cargo may be carried
  3. C. Carrying the cargo in that tank is prohibited
  4. D. The vehicle may continue if its destination is nearby

Correct answer: C. – Carrying the cargo in that tank is prohibited

The Tennessee manual directs drivers to inspect all tank vehicles for leaks and states that liquids or gases must not be carried in a leaking tank. A violation can result in a citation and the vehicle being prevented from continuing. A small leak, non-hazardous cargo, or a nearby destination does not create an exception.

Question 6

Bulkheads eliminate the need to consider weight distribution when loading or unloading a tank vehicle.

  1. A. TRUE
  2. B. FALSE

Correct answer: B. – FALSE

Bulkheads divide a liquid tank into smaller compartments, but they do not remove the need to manage front-to-rear weight distribution. When individual compartments are loaded or unloaded, the driver must pay close attention to how the weight is placed. Too much weight must not be concentrated at the front or rear of the vehicle.
