Sample Mississippi Tanker Test Questions

Question 1

After stopping a partially filled liquid tank vehicle on level pavement, why should you maintain steady pressure on the brake pedal?

  1. A To make the parking brake apply automatically
  2. B To prevent the liquid from expanding
  3. C Because liquid surge can push the vehicle forward or backward
  4. D To close the tank’s discharge valves

Correct answer: C – Because liquid surge can push the vehicle forward or backward

Liquid in a partially filled tank surges back and forth during a stop. When a wave reaches an end of the tank, it pushes the vehicle in the direction the liquid is moving. Keep steady brake pressure and do not release it too soon while bringing the vehicle to a complete stop.

Question 2

If liquid leaking from your tank vehicle causes a spill, which financial consequence is possible?

  1. A You may be held liable for cleanup costs
  2. B Cleanup costs can never be charged to you
  3. C You must always pay every cleanup expense
  4. D Only the shipper can be responsible for cleanup

Correct answer: A – You may be held liable for cleanup costs

The Mississippi Commercial Driver’s License Manual warns that a driver may be liable for cleaning up a tank-vehicle spill. It does not state that the driver is liable in every case. Check under and around the vehicle for leakage, and do not carry liquids or gases in a leaking tank.

Question 3

Before loading, unloading, or moving a tank vehicle, what must you verify about the intake, discharge, and cut-off valves?

  1. A All valves are fully open
  2. B All valves are fully closed
  3. C All valves have been freshly cleaned
  4. D Each valve is in the correct position for the operation

Correct answer: D – Each valve is in the correct position for the operation

Valve positions depend on whether the tank vehicle is being loaded, unloaded, or moved. Inspect the intake, discharge, and cut-off valves and confirm that each is correctly positioned before beginning the operation. A tank vehicle must not be driven with open valves or manhole covers.

Question 4

During a tank-vehicle inspection, which condition should you look for on the tank body or shell?

  1. A Dents or leaks
  2. B Matching paint and wheel color
  3. C Only faded identification decals
  4. D A polished exterior finish

Correct answer: A – Dents or leaks

Inspect the tank’s body or shell for dents or leaks. Leakage is the most important condition to check on a tank vehicle, including beneath and around the vehicle. Do not carry liquids or gases in a leaking tank; the vehicle may be cited and prevented from continuing.

Question 5

As you prepare to enter a curve in a liquid tank vehicle, which technique is correct?

  1. A Accelerate before entering the curve
  2. B Slow before the curve, then accelerate slightly through it
  3. C Travel at the posted speed regardless of the load
  4. D Wait until you are in the curve to brake firmly

Correct answer: B – Slow before the curve, then accelerate slightly through it

The Mississippi Commercial Driver’s License Manual directs tank drivers to slow down before a curve and then accelerate slightly through it. A tank vehicle can roll over even when traveling at the posted curve speed. Select a safe lower speed before entering the curve rather than waiting until the vehicle is already turning.

Question 6

A tank fitted with baffles is divided into completely separate smaller tanks.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

The statement is false. Baffled tanks contain internal bulkheads with holes through which liquid can flow, so they are not completely separate tanks. Baffles help control forward-and-back surge, although side-to-side surge can still occur. Solid bulkheads, rather than baffles, divide a tank into smaller compartments.
