Final answer:
The option to avoid when carrying cargo is securing it with elastic cords, as they can become loose and create a safety hazard. Filling saddlebags evenly and securing cargo low are best practices for balance and control, while fastening to a sissy bar needs caution to avoid making the vehicle top-heavy.
Step-by-step explanation:
When carrying cargo on a vehicle, such as a motorcycle, there are specific safety guidelines that should be followed to ensure the load is secure and does not create a hazard. Among the options provided, securing cargo with elastic cords should be avoided. Elastic cords can stretch and become loose, which can cause the cargo to shift or even fall off during transport, creating a dangerous situation. Instead, it is advisable to use sturdy straps or cargo nets that are designed for the purpose of securing loads more reliably.
Filling saddlebags evenly is a practice that ensures balanced weight distribution, which is crucial for maintaining handling and stability of the vehicle. Securing cargo as low as possible lowers the center of gravity and contributes to better balance and control while riding. Lastly, fastening excess cargo to the sissy bar can sometimes be acceptable provided the weight is not excessive, and it does not extend too far above the height of the sissy bar, which could also affect handling. Therefore, care must be taken to ensure that cargo fastened to a sissy bar does not make the motorcycle top-heavy and harder to control.
