Sample New Hampshire Tanker Test Questions

Question 1

While driving a tank vehicle in New Hampshire, which listed technique is appropriate for a sudden emergency stop?

  1. A Controlled braking
  2. B ABS braking
  3. C Emergency braking
  4. D Parking-brake braking

Correct answer: A – Controlled braking

For a rapid stop, the manual recognizes controlled braking or stab braking. Controlled braking applies the brakes as firmly as possible without locking the wheels, allowing the driver to retain control. Because sudden steering while braking can contribute to a tank-vehicle rollover, steering movements should remain very small.

Question 2

A tank can exceed legal weight limits before it is full when carrying a dense liquid.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

Tank volume alone does not determine whether a vehicle is within legal weight limits. A dense liquid may make the vehicle overweight before the tank is full, so heavy liquids may require a partial load. The permitted amount depends on the liquid’s weight and expansion as well as applicable weight limits.

Question 3

Having bulkheads makes careful weight distribution less important when loading a tank vehicle.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

Bulkheads divide a liquid tank into several smaller tanks, but they do not eliminate weight-distribution concerns. When loading or unloading those smaller tanks, the driver must pay close attention to the loading pattern. Too much weight must not be concentrated toward either the front or rear of the vehicle.

Question 4

What is the primary purpose of baffles inside a liquid tank?

  1. A To form sealed compartments for separate loads
  2. B To make the tank suitable only for food products
  3. C To eliminate all side-to-side liquid movement
  4. D To reduce forward-and-back liquid surge

Correct answer: D – To reduce forward-and-back liquid surge

A bulkhead normally divides a tank into smaller tanks. In a baffled tank, the internal dividers have holes that allow liquid to flow through while reducing forward-and-back surge. Baffles do not prevent side-to-side surge, so the possibility of a rollover remains.

Question 5

What is one function of bulkheads inside a liquid-cargo trailer?

  1. A Dividing the tank into several smaller tanks
  2. B Maintaining a constant cargo temperature
  3. C Improving the tractor’s fuel economy
  4. D Preventing every possible cargo leak

Correct answer: A – Dividing the tank into several smaller tanks

The New Hampshire Commercial Driver’s License Manual describes bulkheads as dividers that create several smaller tanks within a liquid tank. When loading or unloading these smaller tanks, the driver must continue paying close attention to overall weight distribution. Excessive weight must not be placed toward the front or rear.

Question 6

What can liquid surge do when a tank vehicle stops on a slippery surface?

  1. A Push the stopped vehicle forward
  2. B Make the vehicle stop more smoothly
  3. C Cause the trailer to uncouple automatically
  4. D Shorten the vehicle’s stopping distance

Correct answer: A – Push the stopped vehicle forward

Liquid in a partially filled tank keeps moving as the vehicle slows. When the wave reaches the end of the tank, it can push the vehicle in the direction the wave is moving; on ice, this force can shove a stopped truck into an intersection. Braking well in advance and maintaining steady brake pressure help control surge.
