Tanker Endorsement Test
Question 1 |
You are driving a tanker truck. The front wheels begin to skid. Which of these is most likely to occur?
Liquid surge will pull the tank from the truck. | |
You will continue in a straight line and keep moving forward no matter how you
steer | |
The truck will roll over. |
Question 2 |
How would you expect a truck with a cargo tank that has baffles to handle on the road?
The truck will seem heavier than it really is | |
The truck will handle the same way as a tanker without baffles | |
There will be less front-to-back surge than there is in a tanker without baffles |
Question 3 |
A tank endorsement is required for certain vehicles that transport
liquids or gases | |
hazardous materials | |
passengers |
Question 4 |
Side-to-side surge can cause
suspension system failure | |
a rollover | |
overspeeding |
Question 5 |
Empty Trucks:
Stop quicker only when you use the emergency or parking brake | |
May require a longer stopping distance then full trucks | |
Have better traction when stopping than full trucks
|
Question 6 |
When your cargo tank has baffles, what handling effect do you expect?
There will be less front-to-back surge than in a tank without baffles | |
The surge will be slower than in a tank without baffles | |
There will be less side-to-side surge than in a tank without baffles |
Question 7 |
The liquid in a tank with baffles can still have what kind of surge?
Side-to-side | |
Front-to-back | |
Top-to-bottom |
Question 8 |
Liquid-tight separators between compartments inside tanks are called
barriers
| |
baffles
| |
bulkheads
|
Question 9 |
The amount of liquid to load into a tank depends on what?
The legal weight limits | |
Both of the above | |
The amount the liquid will expand in transit |
Question 10 |
An emergency forces you to stop your tanker quickly or crash. You should
use only the emergency brakes | |
lock the brakes with the pedal and hold it there | |
use controlled or stab braking |
Question 11 |
Separators with openings or holes in them, that are between compartments in a
tank are called
baffles
| |
bulkheads | |
barriers
|
Question 12 |
When should the driver of a tanker that has lost its brakes use a truck escape
ramp?
Always
| |
Never
| |
Only if the tank has baffles |
Question 13 |
When you load the small tanks of a cargo tank equipped with bulkheads, you
should check the
water content | |
distribution of weight | |
air-to-fuel ratio |
Question 14 |
You are driving on a clear night. You must dim your headlights from high to
low. You should adjust your speed so you can stop within
the length of your vehicle | |
the distance you can see ahead | |
the distance you will travel in the next 15 seconds |
Question 15 |
You should be very cautious when driving smooth bore tankers, especially when
you are
driving against the wind | |
starting or stopping | |
going uphill or downhill |
Question 16 |
Hauling liquids in tankers requires special care for the following reason(s)
Both of the above | |
Liquid movement
| |
High center of gravity |
Question 17 |
A baffled tanker is one with
separate tanks inside the trailer | |
bulkheads in them with holes that let the liquid flow through. | |
hollow balls floating in the liquid to slow movement |
Question 18 |
Which of these statements about tankers and their center of gravity is true?
Both of the above | |
Much of the load's weight is carried high up off the road | |
Tankers can turn over at the speed limits posted for curves |
Question 19 |
The best way to take a curve in a tanker is to slow to a safe speed before
entering the curve and then ____ as you go through it.
brake lightly | |
downshift twice | |
speed up slightly |
Question 20 |
Which of these statements about stopping distance and speed is true?
You need about twice as much stopping distance at 40 mph as at 20 mph | |
Wet roads can double the stopping distance at any speed | |
Both of the above are true |
Question 21 |
A smooth bore tank is also known as
an un-baffled liquid tanker | |
a liquid tank with baffles | |
a tank made of aluminum |
Question 22 |
You should know the outage needed for the liquids you carry because
tank baffles are not always legal with outage | |
some liquids expand more than others when they get warm
| |
some of the heaviest liquids do not need any outage |
Question 23 |
The movement of the liquid in partially filled tanks is called
waves
| |
surging
| |
splashing |
Question 24 |
How does liquid surge affect the handling of a tanker?
Surge lets you turn corners tighter | |
Surge can move the truck in the direction the liquid waves move | |
Surge increases the wind drag of the truck |
Question 25 |
Separators with openings or holes in them, that are between compartments in a
tank are called
baffles | |
bulkheads | |
barriers |

About the Tanker CDL Test
The Tanker test:
- 20 questions.
- You need 16 correct answers (80%).
- You may be timed. Time limit varies by state.
Tankers carry liquid materials. While some believe tankers are only for carrying hazardous materials, this isn’t true. There are some jobs that require a tanker endorsement but not a HAZMAT endorsement.
We still recommend that if you get your tanker endorsement, you should also get your HAZMAT as well. Many liquid transports are hazardous, and the tanker/HAZMAT combination will open up more jobs for you to haul.
A tanker endorsement is necessary for transporting liquids in a tank having an individual-rated capacity of more than 119 gallons and an aggregate-rated capacity of 1,000 gallons or more.
You will be tested on:
- Inspecting tank vehicles
- Special purpose equipment
- Driving tank vehicles
- High center of gravity
- Danger of surge
- Bulkheads/baffled tanks
- How much to load
- Safe driving rules
- Controlling surge/curves
- Stopping distance/skids
Tankers are great endorsements to have—they add a lot of weight to your resume! Be ready to answer all questions with confidence. How are bulkheads different than baffles? Should a tank vehicle take curves, on ramps/off ramps at the posted speed limit? What three things determine how much liquid you can load?
