The role of barriers when securing cargo is primarily to prevent cargo from shifting or moving during transportation. This is crucial because a stable load contributes to the safety of the vehicle, the driver, and other road users. When cargo shifts, it can change the center of gravity and lead to issues such as loss of control, tipping, or damage to the cargo itself. Barriers, like straps, nets, or walls, are specifically designed to contain and secure the load in place, ensuring it remains stationary throughout the journey. Other options don't align with the primary purpose of barriers. While barriers can sometimes offer visibility (as in the case of some types of netting), their main function is not visibility but security. Adding weight to the load is not a goal when securing cargo, as effective securing should aim to maintain the load's integrity without unnecessarily increasing the vehicle's total weight. Lastly, while barriers can help separate different types of cargo, this is a secondary function and not the main purpose of using barriers in cargo securing. The focus should be on maintaining stability and safety of all contents within the transport vehicle.
