Blind zone of trucks
The blind zone near the car is a section of the road that can not be seen in the car's side mirrors.
Very many motorists, both beginners and experienced, having only a light category or a motorcycle, forget one thing - when driving near a truck, and any large-sized vehicle, one has to take into account the fact that he has so-called dead zones where the driver of you will not see with all his desire.
Even a passenger car has its own dead zone, which is much smaller than that of a truck.
In the "dead" zone of the truck can get like a small car and a completely dimensional car. A truck driver can crush you by starting a maneuver, because he just did not notice you.
The length of the blind zone is about 3 meters ahead and 5 meters back, so that you are noticed, you will need to either get ahead of the tractor or lose speed. If such maneuvers are possible in a real road situation. (another vehicle can be located behind or in front of you).
Yes, by the way, you probably noticed on some trucks installed a number of mirrors at different angles to the road, including downward. These mirrors provide a better view, and accordingly reduce the blind zone. But, it is still there!
