The three mirrors on a car are called the left side mirror (left exterior rearview mirror), the centre mirror (interior rearview mirror), and the right side mirror (right exterior rearview mirror). Together, they form the core visual assistance system for driving. The left and right side mirrors are located on both sides of the car body; they are used to eliminate blind spots and observe the road conditions on the side and rear. Especially when changing lanes or reversing, they need to be adjusted to the appropriate angle to cover the maximum field of view. The coordinated use of the three mirrors can significantly improve driving safety. For example, when reversing into a parking space, the left side mirror is used to judge the distance to obstacles on the left, the centre mirror to confirm the space behind, and the right side mirror to monitor the situation on the right. The reflective films of modern vehicle mirrors are mostly made of aluminum or silver, and some high-end models may use chromium to enhance durability and clarity. New drivers can gradually develop a sense of space by recording the number of tyre rotations or the time spent reversing. In addition, although large vehicles such as school buses may be equipped with additional rearview mirrors, the standard configuration of ordinary family cars still mainly consists of these three mirrors.
