Which practice is essential for preventing tanker rollover?

Answer: C — Taking turns slowly and cautiously

Taking turns slowly and cautiously is essential for preventing tanker rollover because it helps maintain stability and control of the vehicle. Tankers, especially when loaded, have a high center of gravity and a large amount of liquid that can shift during turns. When a driver navigates a turn too quickly, the centrifugal force acting on the tanker can cause the vehicle to lean excessively, increasing the risk of a rollover. By slowing down and approaching turns with caution, drivers can reduce the likelihood of the liquid sloshing around inside the tank, which further helps maintain balance and stability. This careful driving practice is crucial for safely handling the unique dynamics of tanker trucks, ensuring the cargo remains secure and the vehicle stays upright during maneuvers.
