[EmilianoRose]

Driving and changing lanes method for checking the rearview mirror is: 1. When changing lanes, first turn on the turn signal, then observe the rearview mirror; 2. If the vehicle behind is seen in the left rearview mirror occupying about one-fifth of the left edge area, do not turn; 3. When the rear vehicle occupies one-third or half of the entire rearview mirror area in the left rearview mirror and the entire vehicle can be seen, a safe turning operation can be performed. The rearview mirror is a tool that allows the driver to directly obtain external information about the rear, side, and lower parts of the car while seated in the driver's seat. For the convenience of the driver's operation, to prevent traffic safety accidents, and to ensure personal safety, all countries require that cars must be equipped with rearview mirrors, and all rearview mirrors must be adjustable in direction.
