Final answer:
When driving in reverse, the driver must not only use the rear view mirror but also turn their head to look out the back window to ensure clear visibility and safety. The correct answer is a) Use his rear view mirror and c) Turn his head so that he can see completely out the back window.
Step-by-step explanation:
To drive in reverse, the appropriate steps a driver should take include checking the rear view mirror, using side mirrors, checking blind spots, and ensuring that it is safe to proceed. However, the most crucial step is to turn one's head to look out the back window to have a full view of what is behind the car. Just relying on mirrors can leave blind spots which can create dangerous situations.
Therefore, while using the rear view mirror is a part of the process, it is essential to physically turn and look directly out the back to have clear visibility. It helps prevent accidents and allows the driver to respond more accurately to the environment. Therefore, the correct answer is a) Use his rear view mirror and c) Turn his head so that he can see completely out the back window.
