Sample Louisiana Tanker Test Questions

Question 1

After stopping a partially filled liquid tanker on level pavement in Louisiana, why should you maintain steady brake-pedal pressure?

  1. A Because the high center of gravity makes the vehicle lean while stopped
  2. B Because braking prevents the liquid from expanding inside the tank
  3. C Because front-to-back liquid surge can push the vehicle after it stops
  4. D Because the service brake closes the tank's discharge valves

Correct answer: C – Because front-to-back liquid surge can push the vehicle after it stops

In a partially filled tank, liquid continues moving after the vehicle stops and can surge from one end of the tank to the other. When the wave reaches an end, it can push the truck in the same direction. Louisiana tanker guidance instructs drivers to maintain steady brake pressure and not release it too early while completing a stop.

Question 2

A tank vehicle's high center of gravity generally makes it top-heavy and more likely to roll over.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

Tank loads are carried relatively high above the road, creating a high center of gravity. This makes the vehicle top-heavy and increases its rollover risk, especially in curves and on ramps. Tank vehicles should take these curves below the posted speed because a posted curve speed may still be too fast for a tanker.

Question 3

During a tank-vehicle inspection, where should you look for evidence of leaks?

  1. A Only inside the cab
  2. B Only directly beneath the tank
  3. C Only near the top loading area
  4. D Under and around the entire vehicle

Correct answer: D – Under and around the entire vehicle

Leaks are the most important inspection item on a tank vehicle. Look beneath the vehicle and around it, then inspect the tank shell, valves, pipes, connections, and hoses for signs of leakage. A check limited to one location can miss a leak at a joint, valve, or another component.

Question 4

Once a liquid tank is divided by bulkheads, front-to-rear weight distribution no longer requires attention.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

Bulkheads divide a liquid tank into smaller compartments, but they do not eliminate weight-distribution concerns. During loading and unloading, the driver must monitor how weight is placed among the compartments. Too much weight toward the front or rear can create an improper load distribution. Balance remains important even when the tank has bulkheads.

Question 5

Which type of cargo is commonly transported in a smooth-bore tank?

  1. A Dry cement
  2. B Liquid food products such as milk
  3. C Compressed gases
  4. D Gravel and other aggregates

Correct answer: B – Liquid food products such as milk

Smooth-bore, or unbaffled, tanks have no internal baffles to slow liquid movement. They are commonly used for food products such as milk because baffles make the inside of a tank difficult to clean under sanitation requirements. Louisiana's manual warns that these tanks have strong forward-and-back surge, requiring extra care during starts and stops.

Question 6

Which condition should you verify when inspecting a tank's manhole covers and vents?

  1. A The covers are permanently bolted down and the vents are plugged
  2. B Both the covers and vents are locked shut
  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

Inspect manhole covers to confirm that their gaskets are present and that the covers close correctly. Vents must be kept clear so they can operate properly. Before moving the vehicle, also make sure valves and manhole covers are not left open.
