Sample Michigan Tanker Test Questions

Question 1

Which factors determine the amount of liquid that may be loaded into a cargo tank?

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

Correct answer: D – All of the above

The amount loaded depends on the liquid’s weight, applicable legal weight limits, and the amount the liquid will expand during transportation. Dense liquids may cause a full tank to exceed weight limits, while warming liquids need adequate outage for expansion. Michigan’s CDL manual identifies all three factors when determining how much to load.

Question 2

In addition to the liquid’s weight and legal weight limits, what must be considered when deciding how much to load?

  1. A The length of the planned route
  2. B The liquid’s expected expansion in transit
  3. C The number of stops on the route
  4. D The number of baffles in the tank

Correct answer: B – The liquid’s expected expansion in transit

The loader must consider how much the liquid will expand in transit. Cargo tanks should not be filled completely because liquids expand as they warm, and different liquids require different amounts of outage. Trip distance and the number of baffles are not among the three listed factors for calculating the amount to load.

Question 3

When bringing a tank vehicle to a stop, maintain steady brake pressure and:

  1. A release the brakes immediately when the vehicle slows
  2. B avoid releasing the brakes too soon
  3. C pump the brakes throughout every normal stop
  4. D apply the brakes abruptly near the stopping point

Correct answer: B – avoid releasing the brakes too soon

Use steady brake pressure and do not release the brakes too soon while coming to a stop. Begin braking well in advance and allow additional following distance because liquid surge affects the vehicle’s handling. Abrupt braking or steering can make the tank vehicle unstable and may contribute to a rollover.

Question 4

Except for hazardous waste, when is a shipper’s certification not required for hazardous material transported by motor vehicle?

  1. A When the shipment weighs less than 500 pounds
  2. B When the trip remains within one state
  3. C When the material is transported in a cargo tank supplied by the carrier
  4. D When the driver has a tank endorsement

Correct answer: C – When the material is transported in a cargo tank supplied by the carrier

Federal hazardous-materials rules provide an exception when the material is transported by motor vehicle in a cargo tank supplied by the carrier, unless the shipment is hazardous waste. Michigan’s CDL manual uses a carrier-provided cargo tank as an example of this certification exception. A tank endorsement alone does not remove the certification requirement.

Question 5

Bulkheads eliminate the need to consider weight distribution while 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 weight distribution remains important. When loading or unloading individual compartments, the driver must avoid placing excessive weight at either the front or rear of the vehicle. An unbalanced load can adversely affect handling and axle loading.

Question 6

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

  1. A Expansion of the liquid
  2. B Forward-and-backward liquid surge
  3. C All side-to-side liquid movement
  4. D Movement caused only by high temperatures

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

Baffles contain openings that allow liquid to flow while reducing forward-and-backward surge. They do not prevent side-to-side surge, which can still contribute to a rollover. The Michigan CDL manual emphasizes that tank vehicle drivers must continue making smooth turns and lane changes even when the tank is baffled.
