How to Use the Dotted Line on the Rearview Mirror?

[DelIsabela]

The method of using the dotted line on the rearview mirror is as follows: The area outside the dotted line, due to its smaller radius of curvature, provides a view of the side of the vehicle at a farther distance; the area inside the dotted line, with a larger radius of curvature, offers a clearer view of the side of the vehicle at a closer distance. The dotted line is typically located at the outer third of the rearview mirror, dividing it into two distinct mirror surfaces: the inner area with a larger curvature and the outer area with a smaller curvature. The rearview mirror is one of the important safety components of a motor vehicle, used to observe the road conditions behind the vehicle during reversing and to monitor the surroundings while driving. The reflective coating of the rearview mirror is usually made of silver and aluminum, though some use chromium as the material.
