CDL Tanker questions with complete
solutions A+ rated
Which factor(s) should you consider when determining how much liquid to load into a tank?
A. Weight of the liquid
B. Legal weight limits
C. How much the liquid will expand during transit
D. All of the above - correct answer ✔✔All of the above. Some dense liquids (e.g., some acids) may
exceed legal weight limits. Liquids can also expand as they warm. Therefore you should check the weight
of the liquid, the legal weight limits, and how much the liquid will expand before determining how much
liquid you can safely load.
The effects of liquid surge are reduced by
A. Braking far in advance and increasing your stopping distance
B. Starting, stopping and turning smoothly
C. Hauling thicker liquids
D. All of the above - correct answer ✔✔All of the above. Liquid surge is caused by the movement of
liquid in partially filled tanks. Abrupt start, stops or lane changes will increase the effects of liquid surge.
Thicker liquids will tend to move less, which will reduce the effects of liquid surge.
What should you do to prevent a tanker from rolling over on a curve?
A. Travel at the posted speed limit on a curve
B. Brake aggressively throughout the curve
C. Travel well below the posted speed limit on a curve
D. None of the above - correct answer ✔✔Travel well below the posted speed limit on a curve. Most
rollovers occur around curves. Tests have shown that rollovers can occur at the posted speed limit for a
curve, so you should drive well below the posted speed limit. Also, you should slow down before the
curve, and then accelerate slightly through the curve. You should not aggressively brake while on the
curve.
A baffled tanker has
, A. Separate tanks inside the trailer
B. Interior bulkheads with holes that let the liquid flow through
C. A smooth interior, and is often used to transport food products
D. Dampers that float on the liquid to slow movement - correct answer ✔✔Interior bulkheads with holes
that let the liquid flow through. Unbaffled tankers have a smooth interior and are often referred to as
smooth bore tanks.
A smooth bore tanker is often used to transport
A. Gasoline
B. Heavy liquid
C. Corrosive or acidic liquids
D. Milk or food products - correct answer ✔✔Milk or food products. A smooth bore tanker has no
baffles. Smooth bore tanker are used to deliver milk and food products because sanitation regulations
forbid the use of baffles because of the difficulty in cleaning the inside of the tanks.
Which of the following characteristics make liquid tanker harder to handle?
A. The density of the cargo
B. Low center of gravity of the cargo
C. High center of gravity of the cargo
D. Width of the cargo tank - correct answer ✔✔High center of gravity of the cargo. Tankers carry much of
the their load high above the load - which results in a high center of gravity. The high center of gravity
makes the tanker top-heavy and harder to handle (e.g., increases the risk of rollover).
Which of the following is often referred to as a smooth bore tank?
A. Portable Tank
B. Tank with a stainless steel interior
C. Baffled liquid tanks
D. Unbaffled liquid tank - correct answer ✔✔Unbaffled liquid tank. A smooth bore tanker has no baffles.
Smooth bore tanker are often used to deliver milk and food products because sanitation regulations
forbid the use of baffles because of the difficulty in cleaning the inside of the tanks.
