What principle should guide tanker drivers during loading and unloading operations?

During loading and unloading operations, the principle that should guide tanker drivers is to ensure that the cargo is stable and secured. This is crucial because transporting liquids poses specific challenges due to their movement within the tank. If the cargo is not stable, it can lead to shifting loads, which may increase the risk of tipping or loss of control while driving. Stability is essential for maintaining the center of gravity and ensuring that the vehicle handles properly.

Securing the cargo also involves proper loading techniques and adhering to regulations regarding the maximum allowable weight and ensuring that the liquid is evenly distributed. This helps in maintaining balance during transit, which is particularly important when navigating turns or uneven terrain. Overall, prioritizing stability and security during these operations ensures the safety of the driver, other road users, and the cargo itself.
