Car rearview mirrors can be divided into three main categories based on their installation positions and functional characteristics: exterior rearview mirrors, interior rearview mirrors, and under-view mirrors. Exterior rearview mirrors are typically installed near the doors on both sides of the vehicle, featuring convex or dual-curvature designs to expand the side and rear view, facilitating observation of road conditions during lane changes or turns. The interior rearview mirror is positioned at the centre of the front windshield, predominantly a flat mirror, providing a clear reflection of vehicles behind and the rear cabin interior. Under-view mirrors assist drivers in checking blind spots beneath the front of the vehicle, proving especially useful when maneuvering in confined spaces. Functional rearview mirrors also include anti-glare designs (with automatic or manual adjustment to mitigate high-beam interference at night) and electronic rearview mirrors (which utilize cameras to transmit high-definition images, enhancing visibility in rainy or foggy conditions). Proper adjustment of each rearview mirror's angle (e.g., the exterior mirror should display 1/4 of the vehicle's body, and the interior mirror should align with the horizon) is a crucial step in ensuring driving safety.
