Use of semi-trailer rearview mirror

Rearview mirrors are particularly important during semi-trailer driving and are related to safety issues. How to use the rearview mirror safely?

1. Basically, when the car body is straightened, the rear of the car can be seen.

2. When the semi-trailer is turning:

  When the semi-trailer is turning, there is always one side of the rearview mirror that cannot see the rear of the vehicle. This is normal. When reversing, it is best to find a personal conductor to help.

  According to the instructions of the person in charge behind, it is generally said to fall backwards. For example, if the car is reversing to the right now, as the front of the car, the direction must be driven to the left. When reversing, you must pay attention to the distance between the right rear foot and the intersection. Do not kill the direction when reversing. At this time, turn the direction quickly and straighten the car body as soon as possible. At this time, you need to pay attention to the rear corner on the left. If you can’t come around in one lap, it’s best to make a lap and then reverse the car. When reversing the car, wait for the rear body to lean slightly to the right, and then turn back the wheel, and the body or the front of the car will be straight. If it is not straight, it can be repaired a few times.

  When you have no help, you can only rely on the rearview mirror. If you are a novice, you must pay more attention to the rearview mirror. Sometimes the distance you judge is different from the actual distance. You need to slow down and don’t turn the steering wheel too much. When reversing a semi-trailer, it is always in the opposite direction. When reversing, you must first look for the sense of distance and direction of the car. When reversing, you must carefully observe the rearview mirror.

3. How to adjust the rearview mirror of the semi-trailer:

  For the interior rearview mirror, adjust the left and right positions until the left edge of the mirror just cuts to the right ear of the image in the mirror. This means that under normal driving conditions, you cannot see yourself from the interior rearview mirror, and the up and down positions are just to place the distant horizon in the center of the mirror. For 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 so that the body occupies 1/4 of the mirror range. For the right side rearview mirror, because the driver's seat is on the left side, it is not so easy for the driver to grasp the right side of the body, and sometimes the need for parking on the side of the road, when adjusting the upper and lower positions of the right side rearview mirror The ground area is larger, accounting for about 2/3 of the mirror surface. The left and right positions are also adjusted until the body occupies 1/4 of the area.

Fourth, how to adjust in the morning and evening:

  The reflective film of the rearview mirror is generally made of materials such as silver and aluminum, and their minimum reflectivity is generally 80%. The reflectivity differs between day and night. High reflectivity can have side effects on some occasions. When driving at night, under the illumination of the headlights of the car behind, the reflection of the interior rearview mirror will cause the driver to feel dazzled, which will affect driving safety. For this reason, the angle of the inner rearview mirror in the daytime position should be properly rotated at night to make it suitable for driving requirements.
