Sample Indiana Tanker Test Questions

Question 1

Compared with dry pavement, wet roads may do what to normal stopping distance?

  1. A Double it
  2. B Triple it
  3. C Quadruple it
  4. D Leave it unchanged

Correct answer: A – Double it

The Indiana CDL manual warns that wet roads can double stopping distance. Reduced traction also makes steering and stopping without skidding more difficult. Drivers should reduce their speed by about one-third on a wet roadway to preserve additional stopping room.

Question 2

What is a smooth-bore liquid tank?

  1. A A tank divided into several separate compartments
  2. B A tank equipped with internal baffles
  3. C An unbaffled tank with nothing inside to slow liquid movement
  4. D A tank identified by special exterior insulation

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

Indiana’s CDL manual identifies a smooth-bore tank as an unbaffled liquid tank. Because there is nothing inside to slow the liquid’s movement, forward-and-back surge can be very strong. Drivers must be especially slow and careful when starting or stopping a vehicle with this tank design.

Question 3

When checking tank pipes, connections, and hoses, where should you look especially carefully for leaks?

  1. A Near the exhaust outlet
  2. B Around the joints
  3. C At painted surfaces
  4. D Beside mounting brackets only

Correct answer: B – Around the joints

Tank-vehicle pipes, connections, and hoses must be examined for leakage, especially around their joints. The inspection should be completed before loading, unloading, or driving the vehicle. A leaking tank must not be used to transport liquids or gases.

Question 4

What condition should be verified when inspecting a tank’s manhole covers and vents?

  1. A The covers are permanently bolted shut
  2. B The vents are sealed closed
  3. C The covers have gaskets and close correctly, and the vents are clear
  4. D The covers and vents have matching paint

Correct answer: C – The covers have gaskets and close correctly, and the vents are clear

Manhole covers must have gaskets and close correctly. Vents should be kept clear so they can operate as designed. A tank vehicle must never be driven with its valves or manhole covers open.

Question 5

What should you look for on the body or shell of a tank during inspection?

  1. A Dents or leaks
  2. B Minor paint chips only
  3. C A specific color and finish
  4. D Decorative labels

Correct answer: A – Dents or leaks

The tank body or shell must be checked for dents and leaks. The driver should also inspect beneath and around the vehicle for evidence of escaping liquid or gas. A leaking tank is unsafe and must not be used to transport its cargo.

Question 6

What condition produces liquid surge in a tank vehicle?

  1. A A fully loaded dry-freight compartment
  2. B The vehicle’s high center of gravity by itself
  3. C Liquid moving inside a partially filled tank
  4. D A failure of the tank’s mounting brackets

Correct answer: C – Liquid moving inside a partially filled tank

Liquid surge results from the movement of cargo inside a partially filled tank. During braking, the liquid may move back and forth and push the vehicle in the direction of the wave. This movement can adversely affect handling, especially on a slippery surface.
