Sample New Jersey Tanker Test Questions

Question 1

At which posted curve speeds can a tank vehicle roll over?

  1. A Only the speed posted for an exit-ramp curve
  2. B Only the speed posted for an entrance-ramp curve
  3. C Only the speed posted for a highway curve
  4. D Any of these posted curve speeds

Correct answer: D – Any of these posted curve speeds

Tank vehicles have a high center of gravity, and liquid movement makes them especially prone to rollover. They can roll over even at speeds posted for highway curves and entrance- or exit-ramp curves. In New Jersey, take these curves well below the posted speed, slowing before the curve and accelerating slightly through it.

Question 2

On a wet roadway, a tank vehicle’s normal stopping distance may be approximately:

  1. A Twice as long
  2. B Three times as long
  3. C Four times as long
  4. D Unchanged

Correct answer: A – Twice as long

Wet roads reduce traction and can double a vehicle’s normal stopping distance. The driver must reduce speed to stop within the same space available on dry pavement. Tank drivers should also remember that an empty tank vehicle may require more stopping distance than a full one.

Question 3

Which load is most commonly associated with an unbaffled, or smooth-bore, tank?

  1. A Gasoline
  2. B Milk or another food product
  3. C Corrosive acid
  4. D A very dense industrial liquid

Correct answer: B – Milk or another food product

A smooth-bore tank has no internal baffles to slow the liquid, making forward-and-back surge especially strong. These tanks commonly carry food products such as milk because sanitation requirements prohibit hard-to-clean baffles in such tanks. Drivers must use extra care during starts and stops.

Question 4

What must be evaluated when deciding how much liquid to load into a cargo tank?

  1. A How much the liquid may expand in transit
  2. B The weight of the liquid
  3. C Applicable legal weight limits
  4. D All three factors

Correct answer: D – All three factors

Liquids need room to expand as they warm, and different products require different amounts of outage. A dense liquid may cause the vehicle to reach a legal weight limit before the tank is full. The loading amount must account for expansion in transit, the liquid’s weight, and legal weight limits.

Question 5

During a New Jersey tank-vehicle inspection, which items must be checked?

  1. A Intake, discharge, and cut-off valves
  2. B Pipes, connections, and hoses
  3. C The tank shell, manhole covers, and vents
  4. D All of these items

Correct answer: D – All of these items

Leaks are the most important concern during a tank-vehicle inspection. Examine the shell for dents or leaks and inspect pipes, connections, and hoses, especially around joints. Check the intake, discharge, and cut-off valves for proper positioning. Manhole covers must have gaskets and close correctly, while vents must remain clear.

Question 6

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

Federal regulations prohibit a motor vehicle containing Division 1.1, 1.2, or 1.3 explosives from being parked on or within five feet of the traveled portion of a public street or highway. The hazardous-materials parking rules in the CDL manual state the same five-foot restriction.
