What is the purpose of a driver’s side mirror?

• A. To view the rear passenger seat
• B. To monitor blind spots while changing lanes
• C. To maximize the view of the road ahead
• D. To show traffic signals behind the vehicle

Answer: (B)

The purpose of a driver’s side mirror is to monitor blind spots while changing lanes. This mirror is strategically placed to provide the driver with a view of areas that are not visible through the rearview mirror or the side mirrors. By adjusting this mirror correctly, a driver can see vehicles that may be in adjacent lanes or those approaching from behind in a blind spot. This capability is crucial for safe lane changes and merging, as it helps reduce the risk of collisions with vehicles that might be overlooked from the driver's perspective. Other options might seem relevant but do not fulfill the primary function of the driver’s side mirror. For instance, viewing the rear passenger seat is typically not the purpose of the side mirror, and the view of the road ahead is primarily facilitated by the front windshield and rearview mirror. While traffic signals behind the vehicle can be observed indirectly through the side mirror, that is not its primary design function; it is mainly used for assessing the road and vehicle positions surrounding the driver's vehicle.
