What are the dead areas of the car, and how to prevent a collision with another car or a collision with an object which is at the back of your car?
Dead area of a car is a phenomenon where an overtaking vehicle for a while becomes invisible to the driver either in the rear-view mirror or visually when turning the head.
The dead areas, as a rule, is from the right or left rear of the car, as well as from its rear side. The dead area of the car, which is behind, in size is directly proportional to the dimensions of the car itself.
If a driver does not see a moving car in this area, he can make an abrupt maneuver to the right or left and it's good if the overtaking car is capable of responding in a timely manner to such a maneuver.
Therefore, the first most important rule, which, unfortunately, many drivers neglect, is to turn on turn signals at any change of direction. Only then the car which is in the blind spot will be capable of reacting in time to your maneuver.
Among the technical means that allow to some extent to monitor the blind spots of the car, you can note the special sensors, which can be placed in the rear-view mirrors. If the vehicle with such sensors is in the dead spot, the special signaling device informs the driver about it.
In the absence of such sensors, the drivers have to monitor the dead spots of the car only with the help of special mirrors. But, as a rule, they are not 100% accurate. So, paying attention to the road is the most effective mean.
Panoramic mirrors are one of the types of mirrors which drivers use to control dead zones. But they have a significant disadvantage - they greatly distort the external environment, in which it is impossible to establish the distance to the approaching car or another object.
Professional drivers, as a rule, do not use various additional mirrors to control the dead spots of the car, as a rule, since it takes a lot of time to assess the existing situation.
Let's say, that in order to determine the presence of another car in the dead area which is at the right rear, it is quick enough to lean forward towards the steering wheel and look in the right standard rear-view mirror. The field of view will then be expanded, and you will be able to see the car driving behind near you. The actions of the driver to determine the car in the left dead area are the same.
For example, you decide to drive in reverse, and you are sure that there is no one and nothing behind your car. You get behind a wheel, and looking into the rear-view mirrors, start reversing. But for that time while you assessed the situation, got behind the wheel, started and warmed up (in winter) the engine, anything could happen at the back of your car.
It is reasonable that you can hardly see children or small objects at the back of the car with the help of the rear view mirror, and you will not escape from the collision in this situation.
If your car is not equipped with a rear-view camera or a rear park system, then you should resort to other security considerations.
The ideal option is to take the help of another person. It can be your passenger or just a passerby who will agree to help you.
But still your attention and carefulness, here are the most important trumps in controlling the blind spot.
Do not forget that your car can also get into the dead spot of another car. Try to avoid this. You need to drive to the right or left side at least 3 feet from the rear bumper of the car driving in front of you.
Using these methods, you will maximally take control of the dead areas of the car and avoid many troubles on the roads. Good luck!
