You want to reverse. What must you ensure?

You answered correctly. When reversing, you must allow yourself to be directed by another person if necessary, especially if your view is restricted, and you have to be aware of any load projecting to the rear to avoid collisions or accidents. Relying only on a rear-view reversing camera is not enough because cameras have blind spots and may not show everything behind the vehicle. In all cases, safety and clear visibility are required when reversing.
