Traffic Safety Seminar: How to use the Rearview mirror.
The rearview mirror is an essential part of the car, and it is the driver's "eyes behind the back", which plays a very important role in safe driving. Therefore, it is particularly important to adjust it well. So, how to adjust the rearview mirror correctly? Each car is equipped with three mirrors, namely the left side mirror, the right side mirror and the center mirror. Most cars are equipped with anti-glare rearview mirrors in the car to prevent the glare of the rear vehicle when driving at night, when it is used to turn it upward, that is, the principle of refraction can be used to weaken the rear light, so that the driver clearly judges the relative position of his car and his car. Auto rearview mirror adjustment method:
First of all, the sitting position is adjusted, in order to adjust the rearview mirror;
Second, adjust the rearview mirror:
(1) The adjustment of the central rearview mirror: the left and right position is adjusted to the left edge of the mirror, cut to the right ear of the image in the mirror, under normal circumstances, you can not see yourself from the central rearview mirror, and the upper and lower position is to place the distant horizon in the center of the mirror, the adjustment gist is: Horizontal swing in the middle, ear to the left, that is, the horizontal line in the distance is placed in the middle line of the central rearview mirror, and then move around and put the image of your right ear on the left edge of the mirror.
(2) Adjustment of the left rearview mirror: the upper and lower positions are to place the distant horizon in the center, and the left and right positions are adjusted to the body occupying 1/4 of the mirror range.
(3) Adjustment of the right rearview mirror: because the driver's seat is on the left side, it is difficult for the driver to grasp the situation on the right side of the body. Therefore, the ground area of the right rearview mirror should be larger when adjusting the upper and lower positions, accounting for about 2/3 of the mirror area, and the left and right positions are also adjusted to the body occupying 1/4 of the mirror range.
In addition, many people believe that to eliminate the dead Angle of sight, should try to turn the left and right mirrors outward or downward, in fact, this is a misunderstanding, under normal circumstances, the driver in only turn the eye without looking back, you can see the front of about 200 degrees, and the other about 160 degrees of the range is not visible, in fact, the use of left, right and central mirrors after the rearview mirror, Can only provide an additional 60 degrees or so of visual range, and the remaining 100 degrees can only let the driver take a look back to solve, although many new cars are equipped with double curvature mirrors, but this is only the left, right rearview mirror Angle of view to expand some, still can not fully cover all areas.
How to adjust the rearview mirror
Now in the new century, advanced equipment has made cars smarter and safer, but the left and right mirrors on both sides of the car and the center mirror in the interior of the car, no car is missing them, no matter how eyesore they seem.
There have been many concept cars that use cameras to understand the outside of the car, but it seems to be less functional than the two thin mirrors, and every production car still has a rear-view mirror. Even if the left and right rearview mirror is one of the main sources of driving wind cut sound, but also because it is in the most outer position on both sides of the body and is particularly easy to crash and damage, many automotive engineers have long wanted to use other equipment to replace its function, but so far, no car factory can do it; Whether it's a Mercedes or a BMW.
■ Correct rearview mirror position
So how should the three rearview mirrors located on the left, right, and the center of the windshield be adjusted? The first is an old saying, adjust the standard sitting position first, and then adjust the mirror. First, the central rearview mirror: the left and right position is adjusted to the left edge of the mirror just cut to the right ear of the image in the mirror, which means that in the general driving situation, you can't see yourself from the central rearview mirror, and the upper and lower position is to place the distant horizon in the center of the mirror. Second, the left rearview mirror: the upper and lower positions are to place the distant horizon in the center, and the left and right positions are adjusted to the body occupying 1/4 of the mirror range. Third, right rearview mirror: because the driver's seat is on the left side, the driver's mastery of the right side of the ear is not so easy, coupled with the need for roadside parking sometimes, the ground area of the right rearview mirror is larger when adjusting the upper and lower positions, accounting for about 2/3 of the mirror. The left and right positions are also adjusted to 1/4 of the body area.
Many people think that to eliminate the dead Angle of sight, they try to turn the left and right rearview mirrors outward or downward. In addition, perhaps in order to maintain a neat appearance at any time, research shows that many drivers also adjust the center rearview mirror to take themselves into the car. According to the Sanyang Industrial safety driving Training Center, in order to obtain the most effective rear view Angle, the above way is the most correct adjustment.
Left side mirror adjustment tips: Place the horizontal line at the center line of the rearview mirror, and then adjust the edge of the body to occupy 1/4 of the mirror image.
Right rearview mirror adjustment tips: Place the horizontal line two-thirds of the rearview mirror, and then adjust the edge of the body to occupy 1/4 of the mirror image.
Central rearview mirror adjustment essentials: horizontal swing middle, ear to the left. Place the horizontal line in the middle of the rearview mirror, and then move it left and right, placing the image of your right ear just on the left edge of the mirror.
■ Look back to ensure clearance
A normal driver can see about 200 degrees left and right in front of him if he only moves his eyes without looking back, in other words, there are about 160 degrees that are invisible. Three small mirrors can cover the remaining 160 degrees, it is too "strong mirror"; In fact, the left and right mirrors, plus the center mirrors, can only provide an additional 60 degrees or so of visibility, so what about the remaining 100 degrees? It's simple, just go back and look! This is no joke! I believe that owners who have driven in the United States know that when testing a driver's license in the United States, the actual road test has an important project is that when turning and changing lanes, there is no back to determine whether there is a car. In Taiwan, many people drive with a dozen direction lights, a glance at the left and right mirrors, a look at the car is bent over, and the collision and side collision are often caused by this.
Of course, before turning around to see if there is a car coming from behind, you have to be safe in front of the car. This moment of action, in most cases will not affect the safety of driving. Although many new cars are now equipped with double-curvature mirrors, this is just to increase the perspective range of the left and right mirrors, and still can not fully cover all areas. In addition, it is not difficult to buy a wide-angle mirror on the market, which may further eliminate some dead corners, but the wider the Angle of view, the greater the degree of deformation of the rearview mirror image, and the more difficult the distance in the mirror, which is the "side effects" that the use of wide-angle mirrors must face at the same time.
■ Clean the rearview mirror small secret
Your car may have more visual dead spots than you'd expect than just three rear mirrors can cover, so whether you're changing lanes, turning left or right, or looking over your shoulder when you're sure it's safe to do so.
Left and right rearview mirror because of exposure, it is easy to touch the oil in the air, with a general face paper wipe, always force has not caught, a rain, or vague. Toothpaste is a good rearview mirror cleaner, dip a bit of toothpaste with an obsolete toothbrush, draw a circle from the center to the outside to brush the mirror evenly, and then wash it with clean water. In addition to the cleaning effect of the toothpaste itself, it is also a very fine abrasive, which can remove the grease and stubborn dirt on the left and right rearview mirrors. Even in the event of rain, the water droplets will form a ball and be quickly removed, and will not stick to the mirror into a piece, hindering the safety of driving.
