CDL Quiz 16

1. An emergency forces you to stop your tanker quickly or crash. You should
Lock the brakes with the pedal and hold it there.
Use controlled or stab braking.
Use only the emergency brakes.

2. The movement of the liquid in partially filled tanks is called
Waves
Splashing
Surging

3. Which of these statements about stopping distance and speed is true?
Wet roads can double the stopping distance at any speed.
You need about twice as much stopping distance at 40 mph as at 20 mph.
Both of the above are true.

4. Side-to-side surge can cause
A rollover.
Suspension system failure.
Overspeeding.

5. When your cargo tank has baffles, what handling effect do you expect?
The surge will be slower than in a tank without baffles.
There will be less front-to-back surge than in a tank without baffles.
There will be less side-to-side surge than in a tank without baffles.

6. When you load the small tanks of a cargo tank equipped with bulkheads, you should check the
Water content.
Air-to-fuel ratio.
Distribution of weight.

7. Separators with openings or holes in them, that are between compartments in a tank are called
Baffles.
Barriers.
Bulkheads.

8. Which of these statements about tankers and their center of gravity is true?
Much of the load’s weight is carried high up off the road.
Tankers can turn over at the speed limits posted for curves.
Both of the above

9. 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.

10. How does liquid surge affect the handling of a tanker?
Surge can move the truck in the direction the liquid waves move.
Surge lets you turn corners tighter.
Surge increases the wind drag of the truck.

11. You should be very cautious when driving smooth bore tankers, especially when you are
Going uphill or downhill.
Driving against the wind.
Starting or stopping.

12. A baffled tanker is one with
Separate tanks inside the trailer
Hollow balls floating in the liquid to slow movement
Bulkheads in them with holes that let the liquid flow through.

13. A smooth bore tank is also known as
A liquid tank with baffles
A tank made of aluminium
An un-baffled liquid tanker

14. 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.
The truck will roll over.
You will continue in a straight line and keep moving forward no matter how you steer.

15. The amount of liquid to load into a tank depends on what?
The amount the liquid will expand in transit.
The legal weight limits.
Both of the above.

16. The liquid in a tank with baffles can still have what kind of surge?
Front-to-back
Top-to-bottom
Side-to-side

17. Liquid-tight separators between compartments inside tanks are called
Barriers.
Bulkheads.
Baffles.

18. Outage means
Allowance for expansion of liquid.
How fast the liquid tanks drain.
Liquid weight.

19. You should know the outage needed for the liquids you carry because
Some liquids expand more than others when they get warm.
Tank baffles are not always legal with outage.
Some of the heaviest liquids do not need any outage.

20. Empty trucks
Have better traction when stopping than full trucks.
May require a longer stopping distance than full trucks.
Stop quicker when you use only the emergency or parking brake.
