Good Luck!

All of the following tanker-specific inspections are correct, except:

  • All of these inspections are true and correct

Quote From Page 84 Of The Illinois CDL Manual:

On all tank vehicles, the most important item to check for is leaks. Check under and around the vehicle for signs of any leaking. Do not carry liquids or gases in a leaking tank. In general, check the following:

  • Tank body or shell for dents or leaks.
  • Intake, discharge and cut-off valves. Make sure valves are in correct position before loading, unloading or moving the vehicle.
  • Pipes, connections and hoses for leaks, especially around joints.
  • Manhole covers and vents. Make sure covers have gaskets and that they close correctly. Keep vents clear so they work correctly.
  • Special purpose equipment. If your vehicle has any of the following equipment, make sure it works:
    • Vapor recovery kits.
    • Grounding and bonding cables.
    • Emergency shut-off systems.
    • Built-in fire extinguisher.

Make sure you know how to operate your special equipment. Check the emergency equipment required for your vehicle. Find out what equipment you are required to carry and make sure you have it (and it works).

Regarding stopping distance while driving a tanker, which statement is false?
  • Fully loaded tankers take longer to stop than empty ones
  • All of these statements are true
  • Liquid surge may force your truck forward after you have already come to a complete stop
  • Wet roads double the normal stopping distance

Quote From Page 85 Of The Illinois CDL Manual:

Stopping distance - Keep in mind how much space you need to stop your vehicle. Remember that wet roads double the normal stopping distance. Empty tank vehicles may take longer to stop than full ones.

All of the following require a Tanker endorsement, except:
  • Tank that is permanently attached to the vehicle chassis
  • Portable tanks with a rated capacity of less than 1,000 gallons
  • Portable tank with a rated capacity of 10,000 gallons
  • Large tanks of more than 1,000 gallons enclosed in a box trailer

Quote From Page 84 Of The Illinois CDL Manual:

A "tank vehicle" is used to carry any liquid or gaseous material in a tank that is permanently or temporarily attached to the vehicle or chassis. However, this does not include portable tanks with a rated capacity of less than 1,000 gallons.

What is a Bulkhead?
  • Used to elevate liquid to a higher center of gravity
  • A device that is placed on the top of liquid or gas and compresses it as low as possible to decrease the center of gravity
  • A divider inside a tank to section off liquid or gas
  • Used to hold all liquid or gas to one side of the tank

Quote From Page 84 Of The Illinois CDL Manual:

Some liquid tanks are divided into several smaller tanks by bulkheads. When loading and unloading the smaller tanks, the driver must pay attention to weight distribution. Do not put too much weight on the front or rear of the vehicle.

The amount of liquid to load into a tank depends on:
  • All of these should be taken into consideration when loading liquid into a tank
  • The amount the liquid will expand in transit (outage)
  • Legal weight limits
  • The weight of the liquid
This is a question from page 61 - click here to look up the answer

Quote From Page 85 Of The Illinois CDL Manual:

A full tank of dense liquid (such as some acids) may exceed legal weight limits. For that reason, you often may only partially fill tanks with heavy liquids. The amount of liquid to load into a tank depends on:

  • The amount the liquid will expand in transit.
  • The weight of the liquid.
  • Legal weight limits.

All of the following statements about Liquid Surge are correct, except:
  • When coming to a stop, the liquid will surge back and forth
  • Results from movement of the liquid in partially filled tanks
  • When the surge hits the end of the tank, it tends to push the truck in the opposite direction the wave is moving
  • If the truck is on a slippery surface such as ice, the wave can shove a stopped truck out into an intersection
This is a question from page 61 - click here to look up the answer

Quote From Page 84 Of The Illinois CDL Manual:

Liquid surge results from movement of the liquid in partially filled tanks. This movement can have bad effects on handling. For example, when coming to a stop, the liquid will surge back and forth. When the wave hits the end of the tank, it tends to push the truck in the direction the wave is moving. If the truck is on a slippery surface such as ice, the wave can shove a stopped truck out into an intersection. The driver of a liquid tanker must be very familiar with the handling of the vehicle.

What term describes the following statement: Liquids expand as they warm and you must leave room for the expanding liquid.
  • None of these answers are correct
  • Outage
  • Frontage
  • Contraction
This is a question from page 61 - click here to look up the answer

Quote From Page 85 Of The Illinois CDL Manual:

Liquids expand as they warm and you must leave room for the expanding liquid. This is called "outage."

How much do liquids expand as they warm?
  • Most liquids do not expand when heated
  • Liquids expand at 1kg/m per 10 degree increase
  • different liquids expand by different amounts
  • None of these answers are correct
This is a question from page 61 - click here to look up the answer

Quote From Page 85 Of The Illinois CDL Manual:

Never load a cargo tank totally full. Liquids expand as they warm and you must leave room for the expanding liquid. This is called "outage." Since different liquids expand by different amounts, they require different amounts of outage. You must know the outage requirement when hauling liquids in bulk.
