Side mirrors, also known as wing mirrors, are reflective surfaces mounted on the exterior sides of vehicles. They help drivers see areas behind and to the sides of their cars, improving visibility and safety while driving. Side mirrors can be manually adjusted or equipped with electronic controls for convenience. Many modern vehicles feature additional technologies in their side mirrors, such as blind-spot monitoring systems that alert drivers to vehicles in their blind spots. Some side mirrors also include built-in turn signal lights, enhancing communication with other road users. Properly adjusted side mirrors are essential for safe driving.
