A driver is assigned a type of tank vehicle they have not operated before. What should guide the tank-specific inspection?
Correct answer: That vehicle's operator manual
Tank vehicles differ in design and equipment. The manual directs the driver to consult the vehicle's operator manual to learn the inspection for that tank vehicle.

Before departure, a driver confirms that liquid cargo is leaking from the tank. Which decision follows the tank-inspection guidance?
Correct answer: Do not carry the cargo in the leaking tank
The inspection includes looking under and around the tanker for leaks. A confirmed cargo leak must not be accepted merely because it is slow or the load is reduced.

A tanker has finished unloading. Its operator instructions require the cargo-transfer valves to be closed for road travel. What should the driver verify before moving?
Correct answer: They are secured in the specified closed travel positions
Valve positions must match the vehicle and operation. For the tanker described, the cargo-transfer valves must be closed as specified before travel; the unloading setup must not simply be carried over to driving.

The outside of a cargo tank is dry. Where does the manual specifically direct further leak inspection of its transfer system?
Correct answer: At pipes, hoses, and connections, especially joints
A dry shell does not complete the leak inspection. Pipes, connections, and hoses also need checking, with particular attention to their joints.

A tank's manhole cover appears shut, but the driver has not checked its gasket. What does a complete cover check require?
Correct answer: Verify the gasket is present and the cover closes correctly
The manual calls for manhole-cover gaskets and correct closure. The appearance of a closed latch, or a lower liquid level, does not replace that check.

Debris is obstructing a cargo tank's designed vent. Which condition should the inspection establish before the tank is used?
Correct answer: The vent is clear and able to work correctly
The manual directs drivers to keep vents clear so they function correctly. A blocked vent is not made acceptable by sealing it further or by leaving a cover unsecured.

A particular tanker is equipped with an emergency shut-off system. How should that equipment be treated during its inspection?
Correct answer: Verify that the installed system works
When a tank vehicle has special-purpose equipment such as an emergency shut-off system, the inspection must establish that it works. This does not imply that every tanker has the same equipment or test procedure.

What does the manual mean when it describes a liquid tanker as having a high center of gravity?
Correct answer: Much of the load's weight is carried high above the road
A high center of gravity makes a tanker top-heavy and more susceptible to rollover. It describes the height at which weight is carried, not its front-to-rear distribution.

A partially filled liquid tanker has stopped on an icy surface near an intersection. What danger can remain as liquid moves inside the tank?
Correct answer: A surge striking the tank end can push the truck forward
Liquid can continue surging after the vehicle stops. When the wave hits a tank end, it pushes in that direction; on a slippery surface, that force can move a stopped truck.

A tanker diagram shows solid internal divisions creating several separate smaller tanks. Which arrangement does this describe?
Correct answer: Compartments separated by bulkheads
Bulkheads can divide a liquid tank into smaller tanks. Baffles have openings for liquid flow, while a smooth-bore tank lacks those internal flow-restricting structures.
