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.

Good Luck!

Why do liquid tankers need to be driven more smoothly than most other vehicles?
  • Quick acceleration will cause unnecessary sloshing and control difficulties
  • While stopping, liquid will slosh back and forth
  • During turns, liquid will surge to the side of the trailer, increasing the chance of a rollover accident
  • All of these are correct

Quote From Page 85 Of The Illinois CDL Manual:

In order to drive tank vehicles safely, remember:

  • Drive smoothly - Because of the high center of gravity and the surge of the liquid, you must start, slow down and stop very smoothly. Also, make smooth turns and lane changes.
  • Braking - If you must make a quick stop to avoid an accident, use controlled or stab braking. Also, remember that if you steer quickly while braking, your vehicle may roll over.
  • 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.
  • 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.
  • Skids - Do not over steer, over accelerate or over brake. If you do, your vehicle may skid. On tank trailers, if your drive wheels or trailer wheels begin to skid, your vehicle may jackknife. When any vehicle starts to skid, you must take action to restore traction to the wheels.

Regarding stopping distance while driving a tanker, which statement is false?
  • 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
  • Fully loaded tankers take longer to stop than empty ones

While driving a liquid tanker without Anti-Lock Brakes, all of the following statements are true, except:
  • Use stab braking to avoid an accident
  • Use controlled braking to avoid an accident
  • All of these answers are true
  • Steer quickly and swerve around a hazard while braking at the same time
This is a question from page 61 - click here to look up the answer

Quote From Page 85 Of The Illinois CDL Manual:

To drive tank vehicles safely, you must follow all safe driving rules:

Braking – If you must make a quick stop to avoid an accident, use controlled or stab braking. If you do not remember how to stop using these methods, review Section 2.13. Also, remember that if you steer quickly while braking, your vehicle may roll over.

Which statement about liquid surge is true?
  • Liquid surge will not affect handling and will only affect braking or acceleration
  • Liquid surge only occurs during acceleration or stopping and does not occur during turns
  • On tanker vehicles, brakes are designed to hold the vehicle in place when liquid surges forward
  • When liquid surge hits the end of the tank, it tends to push the truck in the direction the wave is moving
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.

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

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.

What is a Bulkhead?
  • Used to elevate liquid to a higher center of gravity
  • Used to hold all liquid or gas to one side of the tank
  • 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
This is a question from page 61 - click here to look up the answer

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.

What type of tanker trailers are normally unbaffled?
  • Food grade tankers
  • All tanker trucks are equipped with baffles
  • Tankers designed to haul non-liquid products
  • Fuel tankers
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.

How much do liquids expand as they warm?
  • Most liquids do not expand when heated
  • None of these answers are correct
  • different liquids expand by different amounts
  • Liquids expand at 1kg/m per 10 degree increase
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.
