Sample Vermont Tanker Test Questions

Question 1

When bringing a liquid tank vehicle to a normal stop, how should you use the brakes to help control surge?

  1. A Release the brakes just before the vehicle stops
  2. B Maintain steady pressure and do not release the brakes too soon
  3. C Pump the brakes repeatedly throughout the stop
  4. D Wait until the last moment and brake abruptly

Correct answer: B – Maintain steady pressure and do not release the brakes too soon

Keep steady pressure on the brakes and do not release them too soon when stopping a liquid tank vehicle. Brake well in advance and maintain additional following distance. Smooth braking helps control liquid surge, while abrupt braking or a sudden steering movement can cause a skid, loss of control, or rollover.

Question 2

A Vermont CDL applicant is evaluating attached tanks with a combined rated capacity of at least 1,000 gallons. Each tank must exceed what individual capacity for the vehicle to meet the tank-vehicle definition?

  1. A 50 gallons
  2. B 75 gallons
  3. C 100 gallons
  4. D 119 gallons

Correct answer: D – 119 gallons

Federal CDL rules define a tank vehicle as a CMV designed to transport liquid or gaseous material in attached tanks that individually hold more than 119 gallons and together hold at least 1,000 gallons. The tanks may be permanently or temporarily attached. The 119-gallon threshold alone is not sufficient without the aggregate-capacity condition.

Question 3

What consequence should a driver expect if a tank inspection reveals a leak?

  1. A The cargo must always be returned to the original shipper
  2. B The trip may continue if the driver reduces speed
  3. C Only a warning will be issued if the leak is small
  4. D The driver may be cited, prevented from continuing, and held responsible for spill cleanup

Correct answer: D – The driver may be cited, prevented from continuing, and held responsible for spill cleanup

The Vermont CDL manual directs drivers not to transport liquids or gases in a leaking tank. A driver operating such a vehicle may be cited and prevented from driving farther. The driver may also be liable for cleaning up a spill, making leak checks one of the most important parts of a tank-vehicle inspection.

Question 4

Which statement correctly describes the relationship between baffles and bulkheads in a liquid tank?

  1. A The terms describe identical solid tank dividers
  2. B Baffles create sealed compartments, while bulkheads always permit liquid flow
  3. C Baffles are bulkheads with openings that allow liquid to pass through
  4. D Baffles eliminate side-to-side surge completely

Correct answer: C – Baffles are bulkheads with openings that allow liquid to pass through

Bulkheads can divide a tank into separate smaller compartments. In a baffled tank, the bulkheads have holes that allow liquid to flow through them. These baffles reduce forward-and-back surge, but they do not prevent side-to-side surge, which can still contribute to a rollover.

Question 5

A cargo tank should be filled completely because eliminating empty space prevents all dangerous liquid movement.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

A cargo tank must not be loaded completely full. Liquids expand as they warm, so sufficient empty space—called outage—must remain for expansion. The required outage varies by liquid, and the amount loaded must also account for the liquid’s weight and applicable vehicle weight limits.

Source: Vermont Commercial Driver’s License Manual — § 8.2.6, “Outage”; § 8.2.7, “How Much to Load?”

Question 6

Liquid tank vehicles are generally top-heavy because much of the load is carried high above the road.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

Tank vehicles have a high center of gravity because much of the cargo weight is carried well above the roadway. This makes them top-heavy and especially vulnerable to rollover. Drivers should take highway curves and entrance or exit ramps well below posted curve speeds when necessary to maintain control.
