What should the primary focus of side mirrors be?

The primary focus of side mirrors should be on areas adjacent to the vehicle. This is crucial for safe driving as side mirrors help drivers monitor blind spots and adjacent lanes, enabling them to make informed decisions during maneuvers such as lane changes or turns. By focusing on areas beside the vehicle, drivers can better assess the proximity of other vehicles, pedestrians, and obstacles, which enhances situational awareness and reduces the risk of collisions.

In contrast, focusing directly in front of the vehicle, while important, is typically the role of the rearview mirror and the front windshield. Similarly, prioritizing passenger comfort does not contribute to safe driving practices, and objects behind the vehicle are primarily monitored through the rearview mirror rather than the side mirrors. Thus, the correct emphasis on areas adjacent to the vehicle directly supports safer driving strategies.
