On wide and smooth roads, if there are few vehicles, there are often many speeding vehicles, because sometimes they are speeding without paying attention and not feeling that they are speeding. Of course, some people also know that they are speeding, and think that their driving skills are good, and there will be no problem with a little speeding. But now there are a lot of speed measurement equipment, and if you keep speeding, there is a high probability of being captured. So some people said, the place where the speed is measured is fixed, if I was speeding before, I am used to looking at my speed before the speed measurement point, and suddenly I find that I am speeding, at this time, I can avoid the capture by stepping on the brakes and slowing down?
First of all, let's first understand how the speed camera works? There are two main methods: radar speed measurement or laser speed measurement, but the principle is the same. When the vehicle enters the monitoring range of the speed radar, the device emits a radar wave or laser beam to the vehicle. These beams are reflected back after encountering the vehicle and are picked up by the camera. Based on the time difference between the beam emission and reception, the speed of the vehicle can be calculated through a series of formulas. As the vehicle continues to drive past the camera, the device continuously makes such measurements to obtain the vehicle's velocity as it passes through the camera area. If you reach the capture point and still exceed the speed limit, the camera will start to capture, and usually take two to three photos, indicating the speed of the car passing through the capture point.
The effective distance captured by the camera is generally between 10-60 meters, and the farthest is not more than 60 meters. The radar monitoring distance is generally 100-200 meters, but the determination of speeding behavior is generally based on the effective distance of the camera, so no matter how advanced the speed measurement equipment, as long as the speed is reduced to the specified range 60 meters away from the camera, it will generally not be captured. Of course, if you want to be more safe, it is best to reduce the speed of the vehicle within the monitoring range of the radar, that is, when the distance is 100 meters, there must be no problem when the speed drops to the specified range. Although 100 meters seems to be a long way away, if you are on the highway, it will only take 3 seconds, so you should be more vigilant and slow down in advance when driving at high speed.
Therefore, if you apply the brakes after seeing the speed test, whether you can avoid the penalty or not, the most important thing is how far away you see the speed camera, and what your speed is. If you see it from a distance of one kilometer, it will definitely be too late to slow down by pressing the brakes, even if you just release the accelerator without stepping on the brakes, it is no problem to slow down while coasting. Generally speaking, if you don't exceed the speed limit much, the maximum is not more than 20%, assuming you run 144km/h at high speed, and it is completely too late to start decelerating when you are 150 meters away from the camera without braking suddenly. On a road with a speed limit of 80, assuming a speed of 96, it is completely too late to slow down when you apply the brakes at a distance of 110 meters. Of course, if you apply the brakes hard, the distance can be closer. If you're driving at a higher speed, you'll need to travel a longer distance to start slowing down. It needs to be judged according to the actual situation, and there is no fixed distance standard.
Generally speaking, when driving at high speeds, if there is no vehicle or personal danger, do not press the brakes hard to slow down sharply. Because slowing down too fast may be dangerous, the rear vehicle is also driving at high speed, and there is no abnormal situation in front of you, suddenly there is a sudden sudden braking, the rear vehicle must have no time to react, and the possibility of rear-end collision is extremely great. Of course, speeding is not recommended, and there are many traffic accidents caused by speeding, especially major traffic accidents. Because the stability of the vehicle will deteriorate after speeding, especially when turning or changing lanes, it is easy to lose control due to excessive centrifugal force, and there is no time to react in case of emergency, so you can only watch the accident occur. Whether it is on the urban road or on the highway, the blow to speeding is very strong, and there are speed measuring devices everywhere, because the harm of speeding is great. Therefore, it is recommended that all car owners follow the speed limit regulations on any road and do not exceed the speed limit.
If you accidentally exceed the speed limit and want to avoid the capture, you can't brake until you are close, you need to improve your attention, and start to reduce the speed when you are far away. Pay more attention to the roadside signs during driving, generally when the distance is 500 meters, there will be a reminder board, which says 500 meters ahead of the speed measurement. Don't disagree, as long as there is this sign, then there must be a snap, and you need to drive carefully. And there will be a prompt in front of all speed measurements, even mobile speed measurements are prompted, and secret speed measurements are not allowed. If you don't have so much energy to observe the roadside signs, you can turn on the navigation, and the navigation will prompt you in advance after the speed measurement, how many meters ahead there is a speed measurement, please pay attention to the speed. And where there is no speed measurement capture, if you exceed the speed limit, it will also prompt you and slow you down, which is very practical. Obeying the speed limit and driving safely is the most important thing for drivers.
