Tanker/Hazmat CDL – Q&A
Liquid surge is caused by: ✔️Ans - movement of the liquid product in
the cargo tank
Knowing the outage needed for the liquids is important because: ✔️Ans -
some liquids expand more than others when they get warm
What will liquid surge do to the handling of a tank vehicle? ✔️Ans - it
can move the vehicle in the same direction the liquid moves
When your cargo tank has bulkheads, what difference in handling can you
expect? ✔️Ans - there will be less front to back surge than for a smooth
bore
Knowing your center of gravity is important when hauling liquids. It is best
to keep the center of gravity: ✔️Ans - low
Surge is generally: ✔️Ans - front to back and side to side
How would you expect a truck with a baffled cargo tank to handle on the
road? ✔️Ans - there will be less front-to-back surge than there is in
tankers without baffles
When loading a cargo tank with liquid, you must consider which of the
following? ✔️Ans - the legal weight limits in the states in which you will
be driving, the amount the liquid will expand during transit, the weight of
the liquid
You are driving a truck and the front wheels begin to skid. Which of these is
most likely to occur? ✔️Ans - you will continue in a straight line and
keep moving forward no matter how much you steer.
A liquid tank with baffles can still have what kind of surge? ✔️Ans - side
to side
, You are driving a loaded tank vehicle and are exiting a highway using an
off-ramp that curves downhill. You should: ✔️Ans - slow down to a safe
speed before the turn
A smooth bore tank which is loaded to 50% capacity will: ✔️Ans - have
more surge
A smooth bore tank will: ✔️Ans - have more surge than a baffled tank
You need to be extremely cautious when driving smooth bore tankers. This
is especially true when you are: ✔️Ans - starting or stopping
Which of the following is important to remember in an emergency? ✔️Ans
- heavy vehicles can almost always turn more quickly than they can stop
When you unload the smaller tanks of a tank with bulkheads, be careful to
check your: ✔️Ans - weight distribution
Which fires can you use water to put out? ✔️Ans - Tire fires
Which of these statements about emergency steering and tankers is true?
✔️Ans - when making a quick steering movement, do not apply the brakes
Which of these is a good rule to follow when using a fire extinguisher?
✔️Ans - stay upwind of the fire, and aim at the base of the fire
Most tankers have a high center of gravity. Which of the following is
important to remember when pulling a liquid or dry bulk tanker? ✔️Ans -
tankers can roll over at the speed limits posted for curves, most tankers
have a high center of gravity, curves, exit and entrance ramps have speed
limits which are safe for cars, but may be to fast for tankers
Which of these can cause a vehicle to skid? ✔️Ans - oversteering,
overbraking, overacceleration
