When coming to a stop, the liquid in a tank may surge. This can:
Cause the truck to be pushed forward
When loading a tank that is divided into smaller tanks by bulkheads, the load should be:
Heaviest in the middle
Smooth bore tanks have:
Nothing inside to slow the flow of liquids
Which type of products is usually transported by unbaffled tanks?
Food
Cargo tanks should never be completely full because:

When carrying more than 500 gallons of flammable liquid in a tank truck, a driver may drive no more than ________ within a single work period

Tanks equipped with baffles may still roll over because:
There may be a significant side-to-side surge
When loading or unloading a tank that is divided by bulkheads, the person loading the tank should be mindful of:
Equal weight distribution
When loading liquid cargo, you should take into account:
The weight of the liquid
The amount of liquid cargo being loaded into a tank should depend on:
Legal weight limits
When loading liquid cargo, you should keep in mind:
How much the liquid will expand in transit
If you must make a quick stop while transporting liquids, one safe option is to:
Use the controlled braking method
If you must use the controlled braking method while transporting liquid cargo, you should:
Apple the brakes as hard as possible without locking the wheels
If you must make a quick stop while transporting liquids, one safe option is to:
Use the stab braking method
If you must use the stab braking method while transporting liquid cargo, you should:
Apply the brakes completely until the wheels lock up, release the brakes until the wheels start rolling the repeat the process
Before operating a tank vehicle, it is important to:
Check grounding and bonding cables
To drive safely, it is important to remember:
How much distance you vehicle needs to stop
You can lower the risk of jackknifing by:
Steering smoothly
How many hazardous materials classes are there?
9
If you are transporting explosives and your vehicle breaks down, you may notify other drivers:
With electric lights
An improperly placarded vehicle can only be moved:
During an emergency
To operate a vehicle that is used to transport hazardous materials, a driver must have:
A CDL with a hazardous materials endorsement
On a shipping paper describing both hazardous and non-hazardous materials, the hazardous materials may be identified by being:
Listed first
In general, before loading or unloading any flammable liquids, an engine should be:
Turned off
When loading compressed gas, the liquid discharge valves should be:
Opened
When checking a tank vehicle, it is most important to verify that:
There are no leaks
Before driving a tank, you should:
Check pipes, connections, and hoses for leaks
What do bulkheads do?
Separate one large tank into several smaller tanks
Baffled tanks:
Contain bulkheads with holes, allowing liquid to move among sections of the tank
A fully-loaded tank vehicle:
Requires less room to stop that an empty vehicle
A tank endorsement is:
Required to transport both liquids and gases
If a spill occurs from a tank vehicle you are operating:
You may have to pay for clean-up efforts
A surge may occur when:
Liquid cargo quickly moves to the front or rear of a tank
When driving a tank vehicle, the driver should:
Increase their usual following distance
To help control liquid surge, a driver should:
Brake well in advance of a stop
Manhole covers:
Should be closed when a vehicle is being driven
Due to the risk of liquid surge in tanks, you should:
Accelerate slowly
Liquid surge occurs in:
Partially-filled tanks
Front-to-back surge is usually very strong in:
Unbaffled tanks
Before a tank is loaded:
The vehicle should be inspected by the driver
When inspecting a tank, a driver should:
Refer to their specific vehicle’s operator manual
Because of tanks’ high centers of gravity drivers of tanks should:
Reduce their speed on curves
If a tank is found to be leaking, the driver should:
Get the leak fixed immediately
Dense liquids:
May easily cause a tank to exceed legal weight limits
To control a surge, brakes should:
Not be released too quickly after stopping
