Sample Wyoming Tanker Test Questions

Question 1

A commercial motor vehicle carrying Division 1.1, 1.2, or 1.3 explosives must not be parked on or within how many feet of the traveled portion of a public road?

  1. A 5 feet
  2. B 10 feet
  3. C 25 feet
  4. D 50 feet

Correct answer: A – 5 feet

Federal regulations prohibit a vehicle containing Division 1.1, 1.2, or 1.3 materials from being parked on or within 5 feet of the traveled portion of a public street or highway. The Wyoming manual states the same five-foot limit. Other parking restrictions may also apply, but they do not change the required roadside clearance.

Source: 2024 Wyoming Commercial Driver License Manual — § 9.6.1, “Parking with Division 1.1, 1.2, or 1.3 (Class A or B) Explosives”, 49 CFR § 397.7(a)(1) – Parking

Question 2

Why might a tank carrying a dense liquid be loaded only partway?

  1. A To eliminate forward-and-back surge
  2. B To improve the vehicle’s fuel economy
  3. C To remain within legal weight limits
  4. D To avoid leaving room for expansion

Correct answer: C – To remain within legal weight limits

Dense liquids can make a fully loaded tank exceed legal weight limits. A partial load may be necessary to keep the vehicle within those limits. The proper amount to load depends on the liquid’s weight, how much it will expand during transit, and the applicable legal weight limits.

Question 3

During a stop on an icy surface, what can liquid surge do?

  1. A Push a stopped tank vehicle into an intersection
  2. B Make the vehicle stop more smoothly
  3. C Shorten the vehicle’s stopping distance
  4. D Prevent the vehicle’s wheels from skidding

Correct answer: A – Push a stopped tank vehicle into an intersection

In a partially filled tank, liquid moves back and forth as the vehicle stops. When the wave strikes the end of the tank, it pushes the vehicle in the direction the liquid is moving. On ice or another slippery surface, that force can shove an already stopped tank vehicle forward, even into an intersection.

Question 4

Which condition is the most important tank-specific inspection item on every tank vehicle?

  1. A Proper tire inflation
  2. B Signs of leaks
  3. C Exterior cleanliness
  4. D Proper brake adjustment

Correct answer: B – Signs of leaks

The Wyoming CDL manual identifies leaks as the most important tank-vehicle inspection item. The driver should check beneath and around the vehicle and inspect the tank shell, valves, pipes, connections, hoses, manhole covers, and vents for leakage. A tank that leaks liquid or gas must not be used to carry that cargo.

Question 5

In which tank is forward-and-back liquid surge especially strong?

  1. A A smooth-bore tank
  2. B A baffled tank
  3. C A tank divided into compartments by bulkheads
  4. D All tank types equally

Correct answer: A – A smooth-bore tank

An unbaffled, or smooth-bore, tank has no internal baffles to slow liquid movement. As a result, forward-and-back surge is especially strong, particularly during starts and stops. Baffled tanks allow liquid to flow through holes in the baffles, but those structures help control forward-and-back surge.

Question 6

During a pre-operation inspection of a tank vehicle equipped with an emergency shut-off system, what must the driver verify?

  1. A The system is painted red
  2. B The system can be reached from the driver’s seat
  3. C The system has clearly readable labels
  4. D The system operates properly

Correct answer: D – The system operates properly

Emergency shut-off systems are special-purpose equipment that must work properly. The driver should inspect the system according to the vehicle operator’s instructions before loading, unloading, or driving. The required condition is proper operation, rather than a particular paint color or label.
