Side mirrors, also known as wing mirrors, are reflective surfaces mounted on the exterior of vehicles. They provide drivers with a view of the area beside and behind the car, helping to eliminate blind spots and enhance safety while driving. Most vehicles have two side mirrors, one on each side, allowing for better visibility of surrounding traffic. These mirrors can be manually adjusted or equipped with electronic controls for convenience. Some modern vehicles also feature additional technologies, such as blind-spot monitoring systems, which alert drivers to vehicles in adjacent lanes, further improving safety on the road.
