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!

While driving a liquid tanker without Anti-Lock Brakes, all of the following statements are true, except:
  • All of these answers are true
  • Use controlled braking to avoid an accident
  • Steer quickly and swerve around a hazard while braking at the same time
  • Use stab braking to avoid an accident
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.

Why do liquid tankers need to be driven more smoothly than most other vehicles?
  • All of these are correct
  • Quick acceleration will cause unnecessary sloshing and control difficulties
  • During turns, liquid will surge to the side of the trailer, increasing the chance of a rollover accident
  • While stopping, liquid will slosh back and forth
This is a question from page 61 - click here to look up the answer

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.

All of the following tanker-specific inspections are correct, except:
  • All of these inspections are true and correct
  • Make sure intake, discharge, and cut-off valves are in the correct position before loading, unloading or moving the vehicle
  • Make sure manhole covers and vents have gaskets and that they close correctly
  • Check pipes, connections and hoses for leaks
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. 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).

Which statement below is false?
  • Liquid tankers are harder to stop in an emergency than other types of vehicles
  • All tankers have baffle devices to limit sloshing of liquids
  • Liquid tankers are easier to roll over
  • Tanker vehicles have a higher center of gravity
This is a question from page 60 - click here to look up the answer

Quote From Page 84 Of The Illinois CDL Manual:

Hauling liquids in tanks requires special skills because of the high center of gravity and liquid movement. A high center of gravity means that much of the load's weight is carried high up off the road. This makes the vehicle top-heavy and easy to roll over. Liquid tankers are especially easy to roll over. Tests how that tankers can turn over at the speed limits posted for curves. Take highway curves and on-ramp/off-ramp curves well below the posted speed limits.

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

On all tank vehicles, the most important item to check for is:
  • Baffles are not damaged
  • Leaks from the tank
  • Grounding and bonding cables are working properly
  • 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.

Unbaffled liquid tankers are sometimes called:
  • Selective range tanks
  • Unrestricted tanks
  • Free flow tanks
  • Smooth bore tanks
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.

What is a Bulkhead?
  • A divider inside a tank to section off liquid or gas
  • Used to hold all liquid or gas to one side of the tank
  • 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
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.
