What can happen if cargo shifts during transit?

When cargo shifts during transit, it can significantly impact the stability of the vehicle, which is why the correct answer focuses on the risks associated with this issue. Shifting cargo can alter the center of gravity of the truck and create uneven weight distribution. This instability can make it difficult for the driver to control the vehicle, increasing the likelihood of tipping over, especially when turning or navigating curves. Additionally, an improperly secured load can also lead to loss of control, resulting in accidents that could cause injury or damage to the truck and other road users.

In contrast, the other options imply benefits that are not realistic when cargo shifts. Increased fuel efficiency, enhanced vehicle performance, and improved cargo distribution cannot occur if the load is not secured correctly; instead, the priority in such situations should always be on maintaining stability and safety.
