To get the best angle of the rear-view mirror position, we must first adjust our seat position, otherwise it is difficult to sit and observe the rear-view mirror to get the best angle. The correct sitting posture should be that the driver's body can keep upright, and when holding the steering wheel, it can also ensure that the arm has a certain degree of bending, while the leg can still keep natural bending when stepping on the brake and clutch pedal to the bottom.
Next, adjust the car rear-view mirrors. In principle, the adjustment of the rear-view mirrors on both sides is basically similar. The car body area should not exceed 1/4 of the mirror space, and the distant horizon should be in the middle of the mirror. However, the right rear-view mirror is farthest from our driver's position, so it can make more space on the ground. The adjustment of the interior central rear-view mirror is relatively simple. Just map the rear window on the rear-view mirror and keep the distant horizon in the center of the mirror.
