Which safety measure is essential for managing heavy loads while driving?

Properly securing the load is essential for managing heavy loads while driving because it directly affects the stability of the vehicle and the safety of both the driver and other road users. When a load is secured correctly, it reduces the risk of it shifting during transit, which can lead to loss of control, increased stopping distances, or even cargo falling off the vehicle. Preventing movement of the load ensures that the center of gravity remains stable, which is critical for safe handling, steering, and braking.

In contrast, exceeding the speed limit compromises safety by reducing the driver's ability to react to road conditions and increases stopping distances, making it a dangerous practice when managing heavy loads. Minimizing mirror use hinders visibility and awareness of surroundings, which is particularly important when driving with significant weight that may affect maneuverability. Relying solely on backup cameras can lead to blind spots in visibility that may go unchecked, especially for heavy loads that require careful consideration of wider spaces and potential obstructions. Therefore, securing the load is a foundational safety practice in transportation, particularly in the context of handling heavy cargo.
