The estimation of the increased limitation of the visibility in the light commercial vehicles

In the report there is discussed the problem of changing demands in the binding rules concerning the technical conditions. During maintenance, the lack of information from the surrounding of the vehicle is one of the reasons of collisions and accidents. There is a radical limitation of unobstructed observation of the whole area surrounding trucks of N1 category in comparison to the car of M1 category. Vehicles which have the same body and which are designed to transport people - M1 category or load – N1 category, they have different equipment, such as side glazing and back walls. Those who are driving these vehicles do not have comparable and identical visibility. The open loadcarrying body in the truck creates the screen obscuring of the big part of the vehicle's surrounding which precludes the direct observation of the considerable area. The devices of the indirect visibility enable to observe only the part of the area, which is directly invisible. There is an important need to change the regulation as far as construction and vehicles equipment is concerned. This paper offers the change of the philosophy of the regulations requirements in the area of visibility. Technical progress and development in the area of visual transfer devices helps to use them in the vehicles in order to improve the possibility of observing the surrounding of the vehicle. There is no reason to tolerate the worse visual transfer in the vehicles N1 category.
