CDL Practice Test: Tankers

These CDL practice questions are from our High Road Training Program, a CDL test preparation course designed to help you learn the CDL manual.

Our High Road Training Program has the entire CDL manual built right in along with multiple choice questions, a scoring system, and a review system to help reinforce the materials. It's highly effective, super easy to use, and free! Let me tall ya....using The High Road is a thousand times easier than trying to read the entire CDL manual cover to cover.

Tankers Questions

Good Luck!

The amount of liquid to load into a tank depends on:
  • Legal weight limits
  • The amount the liquid will expand in transit (outage)
  • All of these should be taken into consideration when loading liquid into a tank
  • 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.

On all tank vehicles, the most important item to check for is:
  • Grounding and bonding cables are working properly
  • Baffles are not damaged
  • Leaks from the tank
  • Placards (if required) are present and undamaged
This is a question from page 60 - click here to look up the answer

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.

TruckingTruth's Advice:

While there are many other items which can be considered the "most important", most state manuals specifically state that checking for leaks is the most important inspection.

What type of tanker trailers are normally unbaffled?
  • Food grade tankers
  • Fuel tankers
  • Tankers designed to haul non-liquid products
  • All tanker trucks are equipped with baffles
This is a question from page 61 - click here to look up the answer

Quote From Page 84 Of The Illinois CDL Manual:

Unbaffled liquid tankers (sometimes called "smooth bore" tanks) have nothing inside to slow down the flow of the liquid. Therefore, forward-and-back surge is very strong. Unbaffled tanks are usually those that transport food products (e.g., milk). (Sanitation regulations forbid the use of baffles because of the difficulty in cleaning the inside of the tank.) Be extremely cautious (slow and careful) in driving smooth bore tanks, especially when starting and stopping.

While driving a liquid tanker around a curve, you should:
  • Use quick steering movements to keep liquids from collecting on one side
  • Always drive the posted speed for a curve
  • Be confident that your lower center of gravity will reduce the risk of a rollover
  • Understand that the posted speed for a curve may be too fast for a tank vehicle
This is a question from page 61 - click here to look up the answer

Quote From Page 85 Of The Illinois CDL Manual:

Curves: Slow down before curves, then accelerate slightly through the curve. The posted speed for a curve may be too fast for a tank vehicle.

TruckingTruth's Advice:

All maneuvers in a tanker truck should be made slower and smoother than other vehicle types.

When loading a tank, you should:
  • Expect liquid to evaporate and lighten your gross weight over time
  • Never load a cargo tank so that it's totally full
  • Use disposable baffles and barriers when hauling food grade tankers
  • Always load a cargo tank with "filler" so that it's completely filled
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.

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.

What are unbaffled tanks?
  • There are barriers in the tank with holes in them to slow down and restrict surging liquid
  • Small tanks which are loaded and secured onto flatbed trailers
  • Liquid is held in place by multiple barriers, restricting liquid surge
  • There are no barriers inside to slow down or stop liquid from surging

Unbaffled liquid tankers (sometimes called "smooth bore" tanks) have nothing inside to slow down the flow of the liquid. Therefore, forward-and-back surge is very strong.

Be extremely cautious (slow and careful) in driving smooth bore tanks, especially when starting and stopping.

TruckingTruth's Advice:

Unbaffled tankers are much more dangerous to drive, especially when the tanks aren't completely full, as liquid can surge and slosh around in any direction hindering vehicle control.

What is Outage?
  • When liquids expand as they warm
  • When liquids condense as they cool
  • When liquids expand as they cool

How are bulkheads different than baffles?
  • Bulkheads are only allowed in food-grade tankers where baffles can be installed in any type of tanker
  • Baffles are solid barriers in a tanks while bulkheads are barriers with holes in them, allowing liquid to flow through
  • Bulkheads are solid barriers in a tank while baffles are barriers with holes in them, allowing liquid to flow through
  • Bulkheads are only used in gas tankers and baffles are only used in liquid tankers
This is a question from page 61 - click here to look up the answer

Quote From Page 84 Of The Illinois CDL Manual:

Bulkheads: 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.


Baffled tanks: Baffled liquid tanks have bulkheads in them with holes that let the liquid flow through. The baffles help to control the forward and backward liquid surge. Side-to-side surge can still occur. This can cause a roll over.
