What can shifting of metal coils during transport cause in terms of vehicle handling?

Shifting of metal coils during transport can significantly impair vehicle handling and create hazards on the road. When the load within a vehicle is not stable, it can lead to a loss of balance and an uneven distribution of weight. This instability directly affects the driver’s ability to control the vehicle, especially during maneuvers such as turning, stopping, or accelerating.

As the load shifts, it can cause the vehicle to sway or tip, which increases the chances of accidents. Drivers may struggle to maintain a straight path, and the risk of rolling over or colliding with other road users rises. Moreover, sudden shifts can lead to substantial momentum changes that might surprise the driver, making it hard to react appropriately.

In contrast, the other answer choices suggest benefits that are unlikely to occur with shifting loads. For instance, improved aerodynamic efficiency, better fuel economy, and enhanced maneuverability would generally come from a well-secured and balanced load rather than one that shifts unpredictably. This underscores the critical importance of correctly securing metal coils and keeping them stable during transport to ensure safe driving conditions.
