Sample Arizona Tanker Test Questions

Question 1

Under the general rule, before moving a cargo tank containing hazardous material, what must be true of its liquid-discharge valves?

  1. A They may remain open when only a small quantity is carried
  2. B They may remain open for a short move
  3. C They need only be partly closed at low speed
  4. D They must be closed and free of leaks

Correct answer: D – They must be closed and free of leaks

Before driving a cargo tank containing hazardous material, liquid-discharge valves and other closures generally must be closed and free of leaks. This requirement applies regardless of the quantity being carried. Federal regulations provide a narrow exception for certain external emergency self-closing valves on MC 338 cargo tanks containing cryogenic-liquid residue, but ordinary discharge valves must remain closed.

Question 2

When unloading separate compartments formed by solid bulkheads, what must the driver monitor most carefully?

  1. A Tire inflation pressure
  2. B Outage in every compartment
  3. C Front-to-rear weight distribution
  4. D The liquid’s temperature

Correct answer: C – Front-to-rear weight distribution

Bulkheads can divide a liquid tank into several smaller compartments. As those compartments are loaded or unloaded, weight must remain properly distributed from front to rear. The Arizona Commercial Driver License Manual specifically warns drivers not to leave too much weight concentrated at either end of the vehicle.

Question 3

Tank vehicles vary in design. Which source should you consult for the inspection procedures specific to your vehicle?

  1. A The driver’s hours-of-service log
  2. B A generic inspection checklist only
  3. C The vehicle’s operator manual
  4. D The cargo shipping papers

Correct answer: C – The vehicle’s operator manual

Tank vehicles differ in type and size, and their inspection points can vary. The operator manual provides procedures for the particular vehicle being used. A general checklist may help organize an inspection, but it does not replace vehicle-specific instructions. Review the manual before loading, unloading, or driving the tank vehicle.

Question 4

How must manhole covers be positioned before driving a tank vehicle carrying product?

  1. A Open when the weather is dry
  2. B Open during a short move
  3. C Open but held in place with straps
  4. D Closed correctly before movement

Correct answer: D – Closed correctly before movement

Inspect manhole covers and vents before operating a tank vehicle. The covers must have gaskets and close correctly, and the vehicle must not be driven with a manhole cover open. Dry weather, reduced speed, or temporary straps do not satisfy the requirement for a properly closed cover.

Question 5

Under the standard direct-attendance method, how close must a qualified person remain while a hazardous-material cargo tank is being loaded or unloaded?

  1. A Within 5 feet
  2. B Within 25 feet
  3. C Within 50 feet
  4. D Within 100 feet

Correct answer: B – Within 25 feet

Federal hazardous-materials regulations generally require attendance throughout cargo-tank loading and unloading. Under the standard direct-attendance method, the qualified person must remain within 25 feet. During unloading, that person must also be alert and maintain an unobstructed view to the maximum extent practicable. Specified alternative monitoring methods and certain unloading operations are governed by different provisions.

Question 6

An inspection reveals that a tank carrying liquid or gas is leaking. What is the proper response?

  1. A Return directly to the shipper without stopping
  2. B Continue if the leak is too small to affect handling
  3. C Record the leak and complete the delivery
  4. D Stop using the tank; a citation and cleanup liability may follow

Correct answer: D – Stop using the tank; a citation and cleanup liability may follow

Do not carry liquids or gases in a leaking tank. The Arizona Commercial Driver License Manual states that the driver may be cited and prevented from driving farther and may also be liable for cleaning up a spill. A small leak or short remaining distance does not make continued transportation acceptable.
