Sample North Dakota Tanker Test Questions

Question 1

When loading or unloading separate tank compartments divided by solid bulkheads, what must the driver monitor closely?

  1. A. Tire inflation pressure
  2. B. The amount of required outage only
  3. C. Weight distribution between the front and rear
  4. D. The color of the transported liquid

Correct answer: C. – Weight distribution between the front and rear

Solid bulkheads divide a liquid tank into smaller compartments that can be loaded separately. North Dakota’s CDL manual directs drivers to pay attention to weight distribution while loading or unloading these compartments. Too much cargo weight must not be concentrated at either the front or rear of the vehicle.

Question 2

Which items are examples of special-purpose equipment that may need inspection on a tank vehicle?

  1. A. Grounding and bonding cables
  2. B. A vapor-recovery system
  3. C. An emergency shut-off system
  4. D. All of the above

Correct answer: D. – All of the above

A tank vehicle may have vapor-recovery equipment, grounding and bonding cables, or an emergency shut-off system. If any of this special-purpose equipment is installed, the driver must verify that it works. A built-in fire extinguisher is another item specifically identified for inspection when the vehicle is equipped with one.

Question 3

What should be verified when inspecting a tank vehicle’s manhole covers and vents?

  1. A. The covers are permanently bolted shut
  2. B. Every vent is locked before the vehicle moves
  3. C. The covers have gaskets and close correctly, and the vents are clear
  4. D. The covers and vents have matching paint

Correct answer: C. – The covers have gaskets and close correctly, and the vents are clear

North Dakota’s CDL manual directs drivers to make sure manhole covers have gaskets and close correctly. The vents must also be kept clear so they can operate properly. A tank vehicle must never be driven with open manhole covers or valves, and the rest of the tank should be inspected for leaks before loading, unloading, or driving.

Question 4

A commercial motor vehicle contains Division 1.1, 1.2, or 1.3 explosives. It 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 parking a vehicle containing Division 1.1, 1.2, or 1.3 explosives on or within five feet of the traveled portion of a public street or highway. The CDL manual expresses the same five-foot restriction. Other parking restrictions also apply near bridges, tunnels, buildings, gathering places, and open fires.

Question 5

Baffles in a liquid tank generally do not control surge in which direction?

  1. A. Vertically
  2. B. From side to side
  3. C. Forward and backward
  4. D. Equally in every direction

Correct answer: B. – From side to side

Baffles have openings that allow liquid to flow through while helping control forward-and-backward surge. They do not normally prevent side-to-side movement of the liquid. Side-to-side surge can reduce stability and contribute to a rollover, especially during turns or sudden steering movements.

Question 6

How does a tank vehicle’s high center of gravity affect its handling?

  1. A. It improves the vehicle’s stability
  2. B. It prevents liquid from surging
  3. C. It permits curves to be taken at higher speeds
  4. D. It makes the vehicle more likely to roll over

Correct answer: D. – It makes the vehicle more likely to roll over

A high center of gravity places much of a tank vehicle’s load weight high above the road. This makes the vehicle top-heavy and easier to roll over. Tank vehicles should take highway curves and entrance or exit ramps well below the posted curve speed because even a legal posted speed may be too fast for the vehicle’s stability.
