Car side mirrors are reflective surfaces mounted on the exterior of vehicles, typically on both the driver and passenger sides. They allow drivers to see areas behind and beside their cars, helping to enhance visibility and safety while driving. Side mirrors can be manually adjusted or powered, and some models include features like heating or built-in turn signals. These mirrors come in various shapes and sizes, often designed to minimize blind spots. Many side mirrors also have a convex shape, which provides a wider field of view. Properly adjusted side mirrors are essential for safe lane changes and parking maneuvers.
