Which factor is NOT typically considered when assessing vehicle load safety?

When assessing vehicle load safety, the focus is primarily on how well the load is balanced, secured, and fits within the vehicle's designated capacity. Weight distribution is critical because it affects the vehicle's stability and handling. Proper cargo size is important to ensure that items do not exceed the dimensions of the vehicle space and that they remain within legal limits. Securing methods are essential to prevent cargo from shifting during transport, which can lead to accidents or loss of load.

Driving speed, while it affects overall vehicle dynamics, is typically not considered when assessing the safety of how a load is carried. It relates more to the operator's driving practices and external conditions rather than the state of the load itself. Therefore, this factor falls outside the primary considerations for load safety, which are more concerned with how the load is prepared and secured for transport rather than how fast the vehicle is driven.
