What is the result of having too few tie-downs for securing a load?

Having too few tie-downs for securing a load significantly heightens the risk of load shifting during transport. When a load is insufficiently secured, it can move or shift due to shifts in momentum, changes in speed, or even during turns. This movement can affect the stability of the vehicle, potentially leading to loss of control, accidents, or damage to the load itself. Adequate tie-downs are essential for maintaining the load's position and ensuring the safety of the vehicle operation.

In contrast, the other options do not accurately reflect the consequences of inadequate tie-downs. For instance, decreased fuel efficiency and improved aerodynamics could only be achieved under conditions where the load is properly secured and balanced, rather than being related to the number of tie-downs. Additionally, having minimal tie-downs would certainly have an impact on transport safety, contradicting the notion that there would be no impact.
