Sample New York Tanker Test Questions

Question 1

At which locations can a liquid tanker roll over even when traveling at the posted curve speed?

  1. A An off-ramp curve
  2. B An on-ramp curve
  3. C A highway curve
  4. D All three locations

Correct answer: D – All three locations

Liquid tankers have a high center of gravity, making them top-heavy and especially vulnerable to rollover. Tests have shown that they can overturn at speeds posted for curves, including highway, on-ramp, and off-ramp curves. Slow before entering a curve and proceed well below the posted speed, accelerating slightly through the curve when appropriate.

Question 2

Which driving practice helps control liquid surge when approaching a stop?

  1. A Pump the brakes rapidly throughout the stop
  2. B Wait until close to the stop before braking firmly
  3. C Begin braking well in advance and increase following distance
  4. D Steer quickly while applying the brakes

Correct answer: C – Begin braking well in advance and increase following distance

Liquid in a partially filled tank moves forward and backward as vehicle speed changes. To help control this surge, apply steady brake pressure, begin braking well before the stopping point, and increase following distance. Do not release the brakes too soon during a routine stop; use controlled or stab braking only when a quick emergency stop is necessary.

Question 3

A driver holding a New York CDL operates a Class A or B CMV with one portable liquid tank temporarily attached to the chassis. Which rated capacity reaches the threshold for a tank endorsement?

  1. A 100 gallons
  2. B 250 gallons
  3. C 500 gallons
  4. D 1,000 gallons

Correct answer: D – 1,000 gallons

A tank endorsement applies when attached tanks each have a rated capacity greater than 119 gallons and their aggregate rated capacity is at least 1,000 gallons. For one portable tank designed to transport liquid, a 1,000-gallon rating satisfies both capacity conditions. CDL rules require the tank-vehicle endorsement to operate a CMV meeting this definition.

Question 4

During a tank-vehicle inspection, you discover liquid leaking from a connection. What must you do?

  1. A Continue if the leak is minor
  2. B Continue only if the cargo is nonhazardous
  3. C Do not carry liquid or gas in the leaking tank
  4. D Drive directly to the delivery location

Correct answer: C – Do not carry liquid or gas in the leaking tank

The New York State Commercial Driver’s Manual states that carrying liquids or gases in a leaking tank is a crime. Before operating the vehicle, inspect the tank shell, valves, pipes, connections, hoses, covers, and surrounding area for leaks. A driver who operates a leaking tank may be cited and prevented from continuing, and may also be liable for spill cleanup.

Question 5

Which description identifies a smooth-bore tank?

  1. A A tank divided into separate sealed compartments
  2. B A tank containing perforated baffles
  3. C An unbaffled tank with nothing inside to slow liquid flow
  4. D A pressure tank surrounded by special insulation

Correct answer: C – An unbaffled tank with nothing inside to slow liquid flow

A smooth-bore tanker is an unbaffled tank with no internal structure to slow the liquid’s movement. Its forward-and-backward surge can be especially strong when the vehicle starts or stops. Drivers must operate these vehicles slowly and carefully, particularly during acceleration and braking.

Question 6

During a Class 3 flammable-liquid transfer between containers that are not in metallic contact, what is the purpose of bonding or grounding conductors?

  1. A To equalize the liquid levels in the containers
  2. B To neutralize possible static charges during transfer
  3. C To keep the tank valves from opening
  4. D To reduce forward-and-backward liquid surge

Correct answer: B – To neutralize possible static charges during transfer

Federal hazardous-materials rules require metallic bonds or ground conductors to neutralize possible static charges before and during transfers between containers that are not in metallic contact. The connections must be arranged to guard against vapor ignition from a static-electricity discharge. A tank-vehicle inspection should confirm that any grounding and bonding cables are present and working properly.
