Sample Nebraska Tanker Test Questions

Question 1

If cargo leaks or spills from a tank vehicle, which statement about cleanup costs is accurate?

  1. A The driver may be liable for the cleanup
  2. B The driver can never be liable for the cleanup
  3. C The driver is automatically liable in every case
  4. D Only the shipper can have cleanup responsibility

Correct answer: A – The driver may be liable for the cleanup

The Nebraska CDL manual warns that a driver may be liable for cleaning up a spill. This describes a possible consequence, not automatic liability in every incident. Drivers must inspect under and around a tank vehicle for leakage and must not transport liquids or gases in a leaking tank.

Question 2

For attached tanks with an aggregate rated capacity of at least 1,000 gallons, what individual tank-capacity threshold is part of the tank-vehicle endorsement definition?

  1. A More than 50 gallons
  2. B More than 75 gallons
  3. C More than 100 gallons
  4. D More than 119 gallons

Correct answer: D – More than 119 gallons

Federal CDL regulations define a tank vehicle using tanks with individual rated capacities greater than 119 gallons and an aggregate rated capacity of 1,000 gallons or more. The tanks may be permanently or temporarily attached to the vehicle or chassis. Both the individual-capacity and aggregate-capacity conditions are part of the definition.

Question 3

For safer handling, a tanker with a high center of gravity is preferable to one with a low center of gravity.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

A high center of gravity places much of the load’s weight farther above the roadway. This makes the tank vehicle top-heavy and easier to roll over. Tankers can overturn even at posted curve speeds, so curves and ramps should be taken well below those speeds.

Question 4

Which type of liquid movement are tank baffles mainly designed to control?

  1. A Expansion caused by rising temperature
  2. B Forward-and-backward surge
  3. C All side-to-side surge
  4. D Movement caused only by road vibration

Correct answer: B – Forward-and-backward surge

Baffled tanks contain bulkheads with holes that allow liquid to flow through. These baffles help control forward-and-backward surge during acceleration and braking. They do not prevent side-to-side surge, which can still contribute to a rollover.

Question 5

What CDL term describes the space intentionally left in a tank for liquid expansion?

  1. A Surge room
  2. B Headspace
  3. C Outage
  4. D Buffer zone

Correct answer: C – Outage

The expansion space left in a cargo tank is called outage. Liquids expand as they become warmer, so a cargo tank must not be loaded completely full. Because liquids expand by different amounts, the driver must know the required outage for the material being transported.

Question 6

How can hard braking affect a partially filled liquid tanker?

  1. A The liquid remains fixed once the brakes are applied
  2. B The surge pushes only against the rear of the tank
  3. C The liquid can surge back and forth, pushing the vehicle in the wave’s direction
  4. D The liquid settles immediately without affecting handling

Correct answer: C – The liquid can surge back and forth, pushing the vehicle in the wave’s direction

The Nebraska CDL manual explains that liquid in a partially filled tank can surge back and forth during a stop. When a wave strikes an end of the tank, it tends to push the vehicle in the direction the wave is moving. On a slippery surface, surge can even move a stopped tanker into an intersection.
