What must drivers ensure about their cargo regarding visibility?

Drivers must ensure that their cargo does not obscure their view as this is critical for maintaining safe driving conditions. When cargo blocks the driver's line of sight, it significantly increases the risk of accidents. Adequate visibility allows drivers to observe their surroundings, monitor road conditions, and react appropriately to other vehicles and obstacles.

While colorful cargo might help in certain visibility situations, it is not a requirement for safe driving. Moreover, showing the driver’s name or ensuring the cargo is of high value does not contribute to visibility safety. The main focus when it comes to cargo and visibility should be on ensuring that nothing impedes the driver's ability to operate the vehicle safely and effectively.
