What is crucial regarding the contents of the trunk?

The necessity for the contents of the trunk to be properly restrained is vital for safety during vehicle operation. When items are not secured, they can shift or become projectiles in the event of sudden stops or collisions, posing a significant risk to passengers and the vehicle's stability. Properly securing items ensures that they remain in place, minimizing the risk of injury and maintaining the overall safety of the vehicle's operation. Ensuring that heavy or irregular items are restrained protects both the driver and any passengers, as well as prevents damage to the vehicle's interior.
