Sample Utah Tanker Test Questions

Question 1

Which item is classified as special-purpose tank vehicle equipment that must be checked when installed?

  1. A Vapor recovery kit
  2. B Reflective warning triangles
  3. C Spare electrical fuses
  4. D Portable roadside flares

Correct answer: A – Vapor recovery kit

The Utah handbook lists vapor recovery kits as special-purpose equipment on tank vehicles. Other examples include grounding and bonding cables, emergency shut-off systems, and built-in fire extinguishers. When any of this equipment is installed, the driver must check that it works before operating the vehicle.

Question 2

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

  1. A Both are sealed permanently with bolts
  2. B Both are locked with external padlocks
  3. C The covers have gaskets and close correctly, and the vents are clear
  4. D The covers and vents have matching paint and labels

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

Manhole covers should have gaskets and close correctly. Vents must be kept clear so they can operate as designed. The driver should also inspect the tank body, pipes, hoses, connections, and valves for leaks or improper positioning before loading, unloading, or moving the vehicle.

Question 3

Which tank condition produces liquid surge?

  1. A A trailer carrying secured solid cargo
  2. B A low vehicle center of gravity
  3. C A tank that is only partially filled with liquid
  4. D A tank with no mechanical defects

Correct answer: C – A tank that is only partially filled with liquid

Liquid surge results from the movement of liquid in a partially filled tank. Because the tank is not full, the liquid can continue moving as the vehicle accelerates, turns, or stops. When the resulting wave reaches the end or side of the tank, it can push the vehicle and affect handling.

Question 4

A 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

A vehicle containing Division 1.1, 1.2, or 1.3 explosives may not be parked on or within five feet of the traveled portion of a public street or highway. This is a federal hazardous-materials parking rule under 49 CFR § 397.7(a)(1). The handbook presents the same five-foot restriction in its hazardous-materials driving and parking section.

Question 5

What serious hazard can result from side-to-side liquid surge?

  1. A Automatic opening of the manhole covers
  2. B A vehicle rollover
  3. C Immediate failure of every suspension component
  4. D Elimination of forward-and-back surge

Correct answer: B – A vehicle rollover

Side-to-side movement of liquid creates force against the sides of the tank and can contribute to a rollover. Baffles help control forward-and-back surge, but they do not eliminate sideways movement. Tank vehicles already have a high center of gravity, making careful speed control on curves especially important.

Question 6

As a partially filled tank vehicle comes to a stop, how does liquid surge commonly move?

  1. A Straight upward
  2. B Back and forth
  3. C Only downward
  4. D Without exerting force on the vehicle

Correct answer: B – Back and forth

The Utah handbook explains that liquid in a partially filled tank can surge back and forth as the vehicle stops. When the wave reaches the end of the tank, it pushes the vehicle in the direction of the moving liquid. This movement can affect handling and may even move a stopped tanker on a slippery surface.
