Sample Arkansas Tanker Test Questions

Question 1

When deciding how much of a dense liquid may be loaded into a tank, which factors must be considered?

  1. A Applicable legal weight limits
  2. B The liquid’s weight
  3. C The amount the liquid will expand in transit
  4. D All of the above

Correct answer: D – All of the above

The load amount depends on the liquid’s weight, its expected expansion in transit, and applicable legal weight limits. A full tank of a dense liquid may exceed those limits, requiring a partial load. The Arkansas manual also requires sufficient outage, or empty space, for the liquid to expand as it warms.

Question 2

What movement are baffles primarily designed to reduce inside a liquid tank?

  1. A Expansion of the liquid as it warms
  2. B Forward-and-backward liquid surge
  3. C All side-to-side liquid movement
  4. D Movement caused by overloading the rear axle

Correct answer: B – Forward-and-backward liquid surge

Baffles are bulkheads with openings that allow liquid to flow through while reducing forward-and-backward surge. They do not eliminate side-to-side movement. Because side surge can still contribute to a rollover, a driver must continue to turn and change lanes smoothly.

Question 3

Liquid surge caused by cargo movement occurs in tanks that are:

  1. A Divided into completely separate compartments
  2. B Equipped with baffles
  3. C Partially filled
  4. D Completely empty

Correct answer: C – Partially filled

Liquid surge results from the movement of cargo in a partially filled tank. During a stop, the liquid can move back and forth and push the vehicle in the direction of the wave. The driver must understand this handling effect and start, stop, and change direction smoothly.

Question 4

Compared with a full tank vehicle, an empty tank vehicle:

  1. A Always stops in a shorter distance
  2. B May require a longer distance to stop
  3. C Always has the same stopping distance
  4. D Is automatically easier to control during braking

Correct answer: B – May require a longer distance to stop

An empty tank vehicle may take longer to stop than a full one. The Arkansas manual specifically warns drivers not to assume that an empty tank will stop more quickly. The driver must consider the vehicle’s stopping-space needs and maintain an appropriate following distance.

Question 5

Once a liquid tank is divided by bulkheads, front-to-rear weight distribution is no longer an important loading concern.

  1. A True
  2. B False

Correct answer: B – False

Bulkheads divide a tank into smaller compartments, but they do not make weight distribution unimportant. The driver must pay close attention while loading or unloading those compartments. Too much weight at the front or rear can produce improper vehicle and axle loading.

Question 6

Baffles seal a liquid tank into several completely separate compartments.

  1. A True
  2. B False

Correct answer: B – False

Baffled tanks contain bulkheads with holes that allow liquid to flow through. The baffles reduce forward-and-backward surge but do not create sealed, independent compartments. Side-to-side surge can still occur and may contribute to a rollover.
