With the increasing number of vehicles, traffic accidents are increasing year by year. Many traffic accidents occur because of the driving blind area. Ordinary vehicles have driving blind areas, such as mixer truck, truck mounted crane, wrecker, etc. Although the driving blind area can not be completely eliminated, we can greatly reduce the visual blind area by using appropriate methods. From the feeding mixer to introduce how to reduce the visual blind area.

1. 首先是要調(diào)節(jié)中央后視鏡，在駕駛室左右位置調(diào)整到鏡面的左側(cè)邊緣正好切至自己在鏡中影像的右耳際，這就表示，在一般情況下，從中央后視鏡里是看不到自己的，而上、下位置則是把遠(yuǎn)處的地平線置于鏡面中央即可。

1. The first thing is to adjust the center rearview mirror. Adjust the left and right position of the cab to the left edge of the mirror and cut it to the right ear of the image in the mirror. This means that in general, you can't see yourself from the central rearview mirror, but the upper and lower positions are to place the distant horizon in the center of the mirror.

2. 調(diào)整左側(cè)后視鏡，處理上下位置時(shí)把遠(yuǎn)處的地坪線置于中央，左、右位置調(diào)整至車身占據(jù)鏡面范圍的1/4.

2. Adjust the left rear-view mirror. When processing the upper and lower positions, place the far ground line in the center, and adjust the left and right positions until the car body occupies 1 / 4 of the mirror area

3. 調(diào)整后側(cè)后視鏡，因?yàn)轳{駛座位位于左側(cè)，因此駕駛員對車輛右側(cè)的情況掌握的不是那么容易，再加上有時(shí)路邊停車的需要，右側(cè)后視鏡在調(diào)整上、下位置時(shí)地面面積應(yīng)留的較大，約占鏡面的2/3.而至于左右位置，則同樣調(diào)整車身占1/4鏡面面積即可。

3. Adjust the rear rearview mirror. Because the driver's seat is on the left side, it is not easy for the driver to master the situation on the right side of the vehicle. In addition, when adjusting the up and down positions of the right side rear-view mirror, the ground area should be larger, accounting for about 2 / 3 of the mirror surface. As for the left and right positions, the car body should also be adjusted to account for 1 / 4 of the mirror area.

4. 自上料攪拌車，如何盡量消除視線死角，很多人覺得，要消除視線死角，都盡量把左右后視鏡往外調(diào)或者往下調(diào)。另外，有研究顯示，很多人誤必須要將中央后視鏡調(diào)整到看到自己才行，其實(shí)這是錯誤的做法，正常情況下。駕駛員在僅轉(zhuǎn)動眼球而不回頭的情況下，約可以看到前方200度左、右的范圍，換句話說，還有約160度是看不見的。事實(shí)上，左右后視鏡再加上中央后視鏡，只能再提供額外約60度左右的可視范圍，剩下的100度左右是看不見的，必須靠我們自己多注意，尤其是轉(zhuǎn)彎的時(shí)候。

4. Since the loading mixer, how to eliminate the dead angle of sight as far as possible, many people think that to eliminate the blind angle of sight, they should try to adjust the left and right rear-view mirrors outward or downward. In addition, studies have shown that many people have to adjust the central rearview mirror to see themselves. In fact, this is a wrong practice. Under normal circumstances. When the driver only turns his eyes without turning back, he can see about 200 degrees left and right in front of him. In other words, he can not see about 160 degrees. In fact, the left and right rear-view mirrors, together with the central rear-view mirror, can only provide an additional visibility of about 60 degrees. The remaining 100 degrees are invisible. We must pay more attention to it, especially when turning.

自上料攪拌車提醒；不僅是混凝土攪拌車、隨車起重運(yùn)輸車、道路清障車，其它車輛在駕駛過程中同樣要注意視覺盲區(qū)，否則很容易造成事故的。

It is not only the concrete mixer truck, truck mounted crane transport vehicle, road obstacle removal vehicle, but also other vehicles should pay attention to the visual blind area in the driving process, otherwise it is easy to cause accidents.
