You should be extremely cautious when driving smooth bore tanks, especially when you are:
Starting or stopping.
Loading and unloading.
Going up and downhill.
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 have any.
An emergency forces you to stop your tanker quickly or crash. You should:
Use light pressure on the brake pedal.
Use controlled or stab braking.
Use only the emergency brakes.
Before loading or unloading the tanker, the first thing you should do is:
Properly secure all of the baffles
Make sure you have all the necessary plans.
Inspect the vehicle.
If you steer a tank vehicle too quickly while braking you:
Can reduce the amount of liquid surge
May cause vehicle to roll over
Decrease your safe stopping distance
What does liquid surge do to the handling of a tanker?
It makes the truck roll easier
It can move the truck in the direction the liquid waves move
Surge raises the wind drag of the truck
The best way to take a curve is to slow to a safe speed before entering the curve, then ________ as you go through it.
Downshift twice
Brake lightly
Accelerate slightly
A traffic emergency requires you to escape to the shoulder or roadside. If possible, slow down to ____ mph before using your brakes.
20
40
30
If an oncoming vehicle drifts into your lane you should:
Move to your right.
Use no less than one full turn of steering wheel to avoid it
Try to stop rather than turn.
Empty tank vehicles:
Need less space ahead than full ones.
Require greater stopping distance than full ones.
Have better traction when stopping than full ones.
When transporting a tanker, you should inspect the cargo within the first _______ miles of the trip.
125
50
75
Hauling liquids in tankers requires special care for two reasons. One reason is the _____ center of gravity.
Wide
Flat
High
Baffled liquid tanks have bulkheads:
That separate the liquids from different areas of the tanks
That increase the amount of side-to-side surges
With holes in them that let liquid flow through them
Hauling liquids in tank vehicles requires special care for two reasons. One reason is:
Extreme weight
Liquid movement
Uneven expansion
Side-to-side surge can cause:
Uneven tire wear.
Tire failure.
Rollover.
Except when you are loading or unloading cargo, the tank liquid discarge valve should always be:
Unlatched
Closed
Open
When your cargo tank has baffles, what handling effect do you expect? (compared to tanks without baffles)
There will be less side-to-side surge
There will be more low surge than quick surge
There will be less front-to-back surge
How would you expect a truck with a baffled cargo tank to handle on the road?
There will be less forward and backward liquid surge
The truck will handle the same as a tanker without baffles.
The truck will seem heavier than it really is.
TRUE or FALSE: The posted speed for a curve may be too fast for a tank vehicle. (#25)
FALSE
TRUE
Portable tanks are:
Can only be loaded when they are attached to the vehicle.
Not allowed to carry loads that are more than 1,000 gallons
Bulk containers that aren't permanently attached to truck
When inspecting the pipe connections and hoses for leaks, pay special attention to:
Suspension wear
Long sections
Joints
Baffles in liquid cargo tanks do not usually prevent _______ surge.
Top to bottom
Side to side
Front to back
Tanks transporting food products are required to be unbaffled because of:
The pre-installed bulkheads
The difficulty in cleaning the inside of the tank
The ease in cleaning the outside of the tank
A full tank of dense liquids (such as some acids):
Will never exceed legal weight limits
May often exceed legal weight limits
Reduces the effect of liquid surge
When you load the small tanks or a cargo tank equipped with bulkheads, you should check your:
Water content.
Air to fuel ratio.
Weight distribution.
If you are driving a tanker and need to steer quickly to avoid a hazard you:
Should not apply the brakes while turning
Will find that tankers are easier to counter steer than most
Should wrap your thumb around the steering wheel
TRUE of FALSE: The clutch should be depressed before making a quick steering movement (#32)
TRUE
FALSE
TRUE of FALSE: Quick steering movements should only be done with the wheels locked. (#21)
FALSE
TRUE
You are driving on a clear night. You must dim your headlights from high to low. You should adjust your speed so that you can stop within:
100 feet.
The distance you will travel in the next 15 seconds.
The distance you can see ahead.
Which of these statements about stopping distance and speed is true?
You need 2x as much stopping distance at 40 mph as at 20 mph
Wet roads can double stopping distance at any speed.
You are driving on a clear night with your low beam lights on. If your headlights let you see about 250 feet ahead of you, you should adjust your speed so that you can stop within about _______ feet.
100
500
250
TRUE or FALSE: The best way to take a curve is to slow to the safe speed before entering the curve, then accelerate slightly through the curve. (#3)
TRUE
FALSE
When should the driver of a tanker that has lost its brakes use a truck escape ramp?
Never.
Always.
Only if the tank is empty.
Vehicle skids are often caused by:
Driving too fast
Loose materials on a road surface
Driving with bald tires
On tank trailers, if your drive or trailer wheels begin to skid, your vehicle may:
Jackknife
Roll over.
Travel in a straight line.
What does liquid surge do to the handling of a tanker?
It can move the truck in the direction the liquid waves move
It makes it roll easier,
It lets you turn corners tighter.
Forward-to-back surge on a slippery surface can:
Cause a truck to rollover
Decrease your mileage
Shove a stopped truck into an intersection
