The inspection checklist a driver used on a previous tanker does not cover the valve arrangement on the newly assigned tank. What should guide the missing tank-specific checks?
Correct answer: The assigned vehicle's operator manual and its inspection procedure
Tank vehicles vary in design and equipment. Use the actual vehicle's operator manual to learn its tank-specific inspection, rather than assuming a previous tanker's routine covers it.

A tanker has arrived and will remain parked while its cargo is unloaded. A driver proposes skipping inspection because no road travel is planned during the transfer. What is the sound response?
Correct answer: Inspect before unloading as well as before driving
The manual calls for inspection before loading, unloading or driving. A stationary transfer still requires the tank vehicle and its equipment to be suitable for the operation.

Before departure, the driver confirms that liquid cargo is seeping from a tank-pipe connection. The tank shell itself appears dry. What should happen?
Correct answer: Correct the leak before carrying the cargo onward
Leak inspection includes piping, hose connections and joints, not only the tank shell. A confirmed cargo leak must not be treated as acceptable merely because it is small or away from the shell. No spill-penalty or repair recipe is given here.

A tanker has finished one operation and is being prepared for a different one. What should the driver verify about its intake, discharge and cut-off valves?
Correct answer: That their positions are correct for the upcoming operation and the actual tank design
The manual requires the correct valve positions before loading, unloading or moving. This does not mean using one universal configuration for every phase or tank. Follow the vehicle's procedure; the question does not prescribe a valve-opening sequence.

A tank's manhole cover appears to latch, but its required gasket is missing. Which conclusion follows the inspection guidance?
Correct answer: The closure is not satisfactory just because the latch catches
The inspection requires manhole covers to have their gaskets and close correctly. Latching is not proof that a cover with a missing required sealing component is ready for service.

During inspection, the driver finds that a protective covering has blocked a tank vent that should be clear for normal operation. What should be established before the tank is used?
Correct answer: That the vent is clear and able to function as designed
The manual says to keep vents clear so they work correctly. Do not substitute an open or loose manhole cover for the tank's designed venting system. Any corrective work must follow the tank's safe procedure.

A tanker has an emergency shut-off system. The prescribed inspection finds that it does not function, although the normal operating valve still works. What is the proper assessment?
Correct answer: The fitted emergency system needs correction; normal valve operation does not make it serviceable
Special-purpose equipment, including an installed emergency shut-off system, must work. Presence of the control or operation of a different valve does not establish emergency-system function. No testing or bypass procedure is supplied.

A driver is unsure which emergency equipment is required for the assigned tank vehicle. What should be done before accepting the equipment as complete?
Correct answer: Establish the applicable requirements, then confirm the required equipment is present and working
The tank section directs the driver to find out the equipment requirements for the vehicle and ensure that the equipment is carried and works. This question does not invent a universal tank-equipment list or cargo threshold.

The tank shell has a newly noticed dent, but no liquid is visible around it. Why is it wrong to omit that area from the tank inspection?
Correct answer: The shell must be checked for dents as well as leaks
The source includes dents and leaks in the tank-body check. The absence of visible leakage does not remove the need to assess damage under the appropriate inspection procedure; no claim is made that every dent has the same severity.

Loading is complete, but a tank manhole cover is still open. The driver proposes a short yard move to the paperwork station before closing it. Which choice follows the tank guidance?
Correct answer: Secure the manhole cover correctly before driving the tanker
The manual says not to drive a tank vehicle with open manhole covers. A short yard move is still movement of the tanker; headspace does not replace the required closure.

A partially filled liquid tanker comes to a stop on a slippery surface. A liquid wave continues toward the front of the tank. What hazard remains even though the wheels have stopped?
Correct answer: The moving liquid can push the stopped vehicle forward
A liquid wave striking an end of the tank pushes in the wave's direction. The manual warns that surge can move a stopped truck on a slippery surface. A complete wheel stop is not proof that liquid motion has ceased.

During an ordinary, controlled stop in a partially filled liquid tanker, the driver wants to release the service brake immediately as the truck first stops, although the liquid is still surging. What is the better approach?
Correct answer: Keep the steady brake pressure needed to hold the stop rather than releasing too soon
The tank guidance warns against releasing brake pressure too soon when stopping because the liquid can continue to move. This is an ordinary-stop principle, not an ABS pumping instruction, emergency braking method or parking procedure.
