A driver is assigned a tank vehicle with fittings and equipment different from the usual tanker. What should establish the inspection details for this vehicle?
Correct answer: The operator's instructions for this particular tank vehicle
Tank vehicles differ in type, size and equipment. The manual directs drivers to use the vehicle's operator manual to learn the inspection requirements for the particular tank, rather than assuming one tank's details fit another.

An empty tanker is parked at a loading point. Its driver plans to inspect it only after filling, just before driving away. Which change is needed?
Correct answer: Inspect the tanker before loading as well
The manual calls for inspection before loading, unloading or driving a tanker. Checking only after filling misses the pre-loading check that the tank and its equipment are safe for the intended cargo.

A pre-departure inspection finds liquid escaping through a tank-shell defect. The liquid is not classified as hazardous material. How should the driver assess the trip?
Correct answer: Do not carry the liquid in that leaking tank
The tank inspection guidance says not to carry liquids or gases in a leaking tank. Nonhazardous classification, a short trip or a gentle route does not make defective containment acceptable. No spill handling or repair procedure is implied.

A tank's shell is dry and undamaged. Before loading, a driver proposes skipping its cargo hoses and pipe joints because the tank body passed inspection. What is being missed?
Correct answer: Leaks can occur in the cargo connections even when the shell is sound
The manual separately calls for checking pipes, connections and hoses for leaks, particularly at joints. A sound tank shell does not establish that the connected cargo plumbing is sound.

A tank's manhole cover latches, but its required gasket is missing. Does the working latch alone establish that the cover is ready for travel?
Correct answer: No; the cover also needs its gasket and proper closure
The inspection includes both the manhole-cover gasket and correct closure. The latch working does not excuse a missing required gasket; the vent is a separate item.

During inspection, a driver finds that a tank vent is obstructed. A coworker says leaving it blocked will help keep the cargo contained. Which assessment is correct?
Correct answer: The vent must be clear so it can function as designed
The manual instructs drivers to keep tank vents clear so they work correctly. Intentionally obstructing a vent is not an acceptable substitute for the tank's proper containment and closure systems.

After work at a loading point, a tank's cargo discharge valve is left open. This tank's instructions require that valve closed for travel. What should the driver do before departure?
Correct answer: Have the valve put in its specified travel position and verify it
Cargo valve positions must be correct for the operation being performed. The stated discharge valve is not ready for travel while open; checking the manhole cover does not replace checking the valve. This does not prescribe a universal position for every vent or special-purpose fitting.

A tanker is fitted with an emergency shutoff system. Its prescribed check shows that it does not work, although the ordinary discharge control works. Which inspection conclusion is sound?
Correct answer: The emergency shutoff has a defect despite the working ordinary control
The manual lists fitted emergency shutoff systems among the special-purpose equipment that must work. A successful ordinary-control check does not establish that the separate emergency function is operational.

This tank vehicle has grounding and bonding cables specified for its operation. One cable is present but visibly broken. Which conclusion follows from the special-equipment inspection guidance?
Correct answer: Being present is insufficient; the specified equipment must also work
Where the vehicle is equipped with grounding and bonding cables, the inspection must establish that they work. Mere presence is not enough. The question does not prescribe a connection sequence, field repair or universal cargo requirement.

A loading plan would leave a liquid tank with no expansion space, even though the liquid will warm during transit. Why is that plan unsound?
Correct answer: The warming liquid can expand and needs reserved space
Liquid can expand as it warms, so the load must leave the required expansion space, called outage. Baffles and sound closures do not replace that space. The amount is cargo-specific; no percentage is asserted.
