How to Adjust the Position of Rearview Mirrors?
2 Answers
Methods for adjusting car rearview mirrors: Adjust the tilt angle so that the car body occupies 1/4 of the mirror; adjust the elevation angle, with the left rearview mirror showing the sky and ground each occupying 1/2 of the mirror; for the right rearview mirror, the sky and ground should occupy 1/3 and 2/3 respectively. Below are detailed instructions: 1. Before adjusting the rearview mirrors, ensure the vehicle seat and steering wheel are properly positioned. 2. The basic principle for seat adjustment is to sit comfortably, have a clear view, and have easy access to the steering wheel. Maintaining a correct sitting posture is a prerequisite for adjusting the rearview mirrors; improper posture will render the adjusted mirrors ineffective. 3. For the central interior rearview mirror, adjust the horizon reflection to the center of the mirror and position the reflection of the right ear to the left edge of the mirror. 4. For the left exterior rearview mirror, adjust the horizon reflection to the center of the mirror and position the reflection of the left side of the car to occupy 1/4 of the right side of the mirror. 5. For the right exterior rearview mirror, adjust the horizon reflection to 2/3 of the mirror's height and position the reflection of the right side of the car to occupy 1/4 of the left side of the mirror. Allowing the ground reflection to occupy more area in the right rearview mirror helps the driver better monitor the road conditions on the right side and makes it easier to gauge the distance between the car body and the curb when parking.
I've been driving taxis for over a decade and have my own method for adjusting rearview mirrors. First adjust the seat position when getting in the car, then set the mirrors after sitting comfortably. For the left side mirror, expose about a quarter of the car body and place the horizon slightly above the center of the mirror - this gives a clear view of the left rear wheel position. The right mirror is trickier to adjust due to the longer distance; I usually position the horizon at two-thirds height of the mirror while keeping the car body occupying one quarter. The interior center mirror is most critical - adjust it to show the entire rear window with all following vehicles' headlights in view. During rainy days, tilt the mirrors slightly downward to avoid water droplet glare. Always remember to check blind spots by turning your head after adjustment - I once nearly hit an electric scooter when I skipped this check. I reconfirm mirror positions before every passenger ride - safety comes first, no room for carelessness. After getting used to this adjustment routine, lane changes feel particularly reassuring.
