To drive safely, it is essential to have good **visibility** of what is happening behind the vehicle. The **rearview mirrors** are mirrors that help the driver see what is happening on the sides and behind the vehicle. In particular, the **interior rearview mirror** is crucial for this task.

- The interior rearview mirror must be adjusted to allow the driver to see clearly towards the rear horizon. This means it should offer a clear view of approximately **60 meters** behind the vehicle. This distance is sufficient for the driver to react in time to any situation that arises behind.

- It is important to remember that, although the rearview mirrors provide good visibility, there are always **blind spots** that cannot be seen through them. Therefore, it is advisable to turn your head and look through the windows to ensure there are no vehicles in those blind spots before performing maneuvers such as changing lanes.


In summary, adjusting the interior rearview mirror to see approximately 60 meters back is essential to maintain safe driving and prevent accidents.
