Sample Missouri Tanker Test Questions

Question 1

Which description meets the CDL definition of a tank vehicle?

  1. A A CMV designed to carry liquids or gases in attached tanks, with an individual rated capacity over 119 gallons and an aggregate rated capacity of at least 1,000 gallons
  2. B Any vehicle carrying a portable tank with a capacity of exactly 100 gallons
  3. C Only a semitrailer equipped with a permanently mounted, un-baffled tank
  4. D Any CMV transporting liquid cargo, regardless of tank capacity

Correct answer: A – A CMV designed to carry liquids or gases in attached tanks, with an individual rated capacity over 119 gallons and an aggregate rated capacity of at least 1,000 gallons

Federal CDL regulations, reflected in Missouri law, define a tank vehicle as a CMV designed to transport liquids or gases in attached tanks. The tanks must have an individual rated capacity greater than 119 gallons and an aggregate rated capacity of at least 1,000 gallons. They may be permanently or temporarily attached to the vehicle or chassis.

Question 2

Which cargo is commonly transported in a smooth-bore, or un-baffled, liquid tank?

  1. A Compressed gas cylinders
  2. B Food liquids such as milk
  3. C Dense acids exclusively
  4. D Dry bulk cement

Correct answer: B – Food liquids such as milk

Un-baffled tanks are commonly used to carry food products such as milk. Baffles are difficult to clean, creating sanitation concerns for these cargoes. Because nothing inside a smooth-bore tank slows the liquid, forward-and-back surge is especially strong, and the driver must be cautious when starting or stopping.

Question 3

A crash hazard requires a rapid stop in a tank vehicle. Which braking technique should you use?

  1. A Hold the brakes hard enough to keep the wheels locked
  2. B Depend only on engine braking
  3. C Rapidly pump the brake pedal
  4. D Use controlled or stab braking

Correct answer: D – Use controlled or stab braking

For a quick stop in a tank vehicle, use controlled or stab braking. Controlled braking applies the brakes as hard as possible without locking the wheels. Stab braking applies the brakes fully, releases them when the wheels lock, and reapplies them after the wheels begin rolling. Avoid quick steering movements while braking because a tank vehicle may roll over.

Question 4

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

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

Bulkheads divide a liquid tank into several smaller compartments, but they do not remove weight-distribution concerns. The Missouri manual directs drivers to pay attention to distribution when loading or unloading these compartments. Too much weight must not be placed at either the front or rear of the vehicle.

Question 5

Why does transporting liquid in a tank require special driving skills?

  1. A The vehicle has a high center of gravity, and the liquid can move inside the tank
  2. B The vehicle has a low center of gravity, but the liquid can move
  3. C Tank vehicles cannot use standard braking techniques
  4. D All tank cargo is classified as hazardous material

Correct answer: A – The vehicle has a high center of gravity, and the liquid can move inside the tank

Liquid tank vehicles combine a high center of gravity with cargo that can surge inside the tank. Carrying much of the load high above the road makes the vehicle top-heavy and easier to roll over. Liquid movement, especially in a partially filled tank, can also affect handling during acceleration, braking, and turns.

Question 6

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

  1. A It is painted red
  2. B It can be reached from the driver’s seat
  3. C Every component has a printed label
  4. D It operates properly

Correct answer: D – It operates properly

Emergency shut-off systems are included among the special-purpose equipment that tank vehicle drivers must inspect. If the vehicle has such a system, the driver must make sure it works. Appearance, color, or labeling does not replace the required operational check.
