The mirror located in front of the windshield inside the cockpit is called the interior rearview mirror, primarily designed to help the driver confirm the situation behind the vehicle. The mirrors located on both sides of the driver and front passenger seats are called side mirrors, used to observe the road conditions behind the car during reversing and to monitor the vehicle's body during driving. The side mirror is one of the important safety components of a motor vehicle's body, used to observe the road conditions behind the car during reversing and to monitor the vehicle's body during driving. Currently, the reflective films for side mirrors in domestic vehicles are generally made of silver and aluminum, with some using chromium. Abroad, chromium mirrors have already replaced silver and aluminum mirrors for vehicle side mirrors. The rearview mirror is a tool that allows the driver, seated in the driver's seat, to directly obtain external information about the rear, sides, and lower parts of the vehicle. For the convenience of the driver's operation, to prevent traffic safety accidents, and to ensure personal safety, all countries require that vehicles must be equipped with rearview mirrors, and all rearview mirrors must be adjustable. When changing lanes to the left, simply look at the left mirror. If overtaking a vehicle on the left and merging ahead, first glance at the side window to feel that you have passed the left vehicle, then check the rearview mirror to confirm that the vehicle appears in the mirror before changing lanes to the left. When changing lanes to the right, the position of the vehicle behind on the right is mainly confirmed through the right rearview mirror. The exact position at which the right rear vehicle appears before changing lanes varies slightly with each car's rearview mirror and can only be judged by habit. There's usually no need to specifically look at the center rearview mirror when changing lanes. However, the center rearview mirror should be constantly monitored while driving. When adjusting, it is recommended to first adjust the seat to a suitable position, then observe the side mirrors. Seeing the vehicle's body in the mirror, with the body area not exceeding 1/4 of the mirror image, is within a reasonable range. In principle, observing the scene behind the vehicle from the side mirrors with the distant horizon centered in the mirror image is ideal. When you can just see the rear vehicle's front wheels in the rearview mirror, the distance between the front and rear vehicles is about 13 meters. Seeing the grille indicates about 6 meters, and just not seeing the grille indicates about 4 meters. Additionally, during emergency braking, it's necessary to appropriately ease the brake based on the distance to provide stopping distance and space for the vehicle behind. Proper use of the center interior rearview mirror can reduce blind spots for vehicles behind, making driving safer.

I've been driving for twenty years, and the three mirrors in the car are usually called the interior rearview mirror, the left side mirror, and the right side mirror. The interior rearview mirror is mounted in the middle of the windshield and is mainly used to check the situation of vehicles directly behind the car. The left side mirror is on the driver's side door and is used to monitor the left blind spot to avoid accidents when changing lanes. The right side mirror is on the passenger door and is responsible for the right blind spot, especially when making a right turn or overtaking at high speed. My experience as a seasoned driver is that when adjusting them, you should let a little bit of the car body show in the mirror, which reduces the blind spot. When reversing, relying on these mirrors in coordination makes things much easier. Regularly cleaning off the dust can also increase the reflectivity at night. Don’t slack off while driving—glancing at them more often can prevent rear-end collisions or side scrapes, making driving much safer.

The three mirrors in the car—the interior rearview mirror, the left side mirror, and the right side mirror—are my three lines of defense for driving safety. The interior rearview mirror directly reflects the traffic conditions behind; the left side mirror helps you detect blind spots on the left; the right side mirror is particularly crucial for preventing accidents during right turns or lane changes. I always emphasize regularly checking if they are loose or dirty while driving, and using hot air to defog them in rainy or foggy weather ensures clear visibility. On highways, adjusting the right mirror to avoid blind spots of large vehicles can prevent tragedies. This habit, cultivated over many years, has significantly reduced my accident rate. Though small, these mirrors can be lifesavers.

When I first got my driver's license, I called the three mirrors in the car the middle one, the left one, and the right one. The middle one is the rearview mirror for checking the traffic behind; the left mirror is used when changing lanes to the left; the right mirror is super practical for reversing or making right turns. During my novice period, I almost hit a stone pier, but fortunately, my instructor taught me how to adjust the mirrors to eliminate the blind spot on the right side. Now, driving in the city is much better—these simple mirrors can really prevent mistakes. Although the names are basic, they're indispensable in actual driving. With a bit more practice, they become second nature.

The three mirrors on a car are officially called the interior rearview mirror, the left exterior rearview mirror, and the right exterior rearview mirror. The interior rearview mirror is fixed in the middle of the windshield for direct rearview; the left exterior one covers the driver's side blind spot; the right exterior one manages risks on the passenger side. Some cars are designed with curved surfaces to reduce distortion and feature heating functions to prevent fogging. When adjusting them, I focus on aligning with the A-pillar angle to avoid blind spots, ensuring the most complete visibility and highest safety. These details are often overlooked daily but prove crucial in emergencies for reliability.

In my daily commute, I call the three mirrors in the car the interior mirror, left mirror, and right mirror. The one in the middle is very convenient for checking the rear when reversing; the left mirror helps observe pedestrians when turning left; the right mirror is a big help when parking at the supermarket or making right turns. Every day when I pick up and drop off my child, I always use the right mirror to keep an eye on the safety of the non-motorized lane. Simply put, these mirrors are basic equipment, and a quick glance while driving helps avoid accidents. Don’t forget to adjust their positions and maintain them—wipe them clean after the wipers to avoid a blurry view.
