As you know, the traffic regulations do not stipulate a specific distance to be observed from the vehicle in front of you. The law only urges motorists to keep a “safe distance”. But what? And how can the driver independently calculate such an important indicator of driving?
Of course, the driver can control the delay while driving. But to calculate the distance, in fact, can only be based on driving experience and the technical capabilities of the car. Although there are a number of objective factors that contribute to good braking.
To begin with, let’s see what the “safe distance” referred to in the SDA is. This refers to the distance the driver can slow down or come to a complete stop in various situations to avoid getting into an accident. In other words, you should not focus on knowledge, but on your own reactions. At the same time, they depend not only on the driver himself, but also on those very objective factors, such as road and climate conditions, wheel adhesion, braking characteristics, as well as the speed and weight of the car.
According to numerous trials and tests, the reaction speed of a person when applying the brake is on average 1.5-2 seconds. The reaction of the brakes themselves takes place in half a second. That is, it takes about 2-2.5 seconds to slow down aggressively. But this is subject to ideal road conditions. Remember that the car in front of you, due to the peculiarities of the braking system, can stop much faster than you. And precipitation or limited visibility play a minus when calculating the time. That’s why we add 1-2 more safety seconds here to an effective delay.
Through primitive mathematical operations, we obtain about 4-4.5 seconds – the average time spent at least on the braking distance. Of course, for each “mate”, it can be less or more. But to thoroughly calculate the value in meters, taking into account the speed and other criteria mentioned above, is quite simple, armed with a stopwatch. Another thing is more important: any delay must be predictable! And here, as already mentioned, only experience will help. However, emergency driving courses will be helpful.
