What is the primary purpose of adjusting mirrors before driving?

The primary purpose of adjusting mirrors before driving is to eliminate blind spots. Blind spots are areas around the vehicle that cannot be directly observed by the driver while looking through the rearview or side mirrors. By properly adjusting the mirrors, drivers can maximize their field of vision, allowing them to better monitor surrounding traffic and increase safety. This adjustment is crucial for making safe lane changes, merging, and understanding the positioning of other vehicles on the road.

Other options, like looking stylish and enhancing vehicle performance, do not contribute to safety in the same way. While reducing glare can be beneficial, it is not the primary reason for mirror adjustments; rather, the key focus is on visibility and awareness of one’s surroundings to avoid accidents.
