what are the angles of error of the radar?


The summer migration continues this weekend and, once again, the roads and highways are overcrowded in the direction of departure as well as in the return. Of course, police and radars of all kinds will also be out.

Like The so-called radar error margin always causes a lot of ink to flowothers going so far as to tell an executive-coordinated government lie and argue their case by referring to questionable measurements of radars that control cars, and different hiccups observed from these devices every year by drivers. However, whether it is a misuse of language or not, there is the official rate of these “margins of error” radars installed on the roads and highways of our area.

Personal or police car radar even fight

And, in this case, what is the point is that the margins mentioned are not the same, depending on whether it is an on-board mobile radar or an automatic fixed radar.. The first, whether installed on a law enforcement vehicle or on a personalized radar vehicle driven by a normal driver, controls the speed with a margin of error of 10 km/h or 10%, depending on the actual speed of the driver at the time of control. Fixed radars, on the other hand, act with margin of error of 5 km/h or 5%, again taking into account the actual speed of the vehicle at the time of the incident. In all cases, when the speed is considered, it is always with the so-called reserved speed and therefore, a priori and the margin of error is reduced in favor of the driver.

Fixed speed cameras theoretically operate with a margin of error of 5 km/h or 5% for the benefit of the driver.© automobile-magazine.fr

Speed ​​limit…

In other words, if you condemn after receiving a ticket for an “insignificant” speed violation in which, for example, a speed of 51 km / h would be written in an area reduced to 50 km / h, this does not mean that you were driving at a speed of 51 kilometers per hour when the flash was activatedsince the PV depends on the speed used to establish the additional speed, which the so-called margin of error (actual speed) is already given, according to the level of information explored in detail in our table below.

Official table of error margin from fixed radar

Speed ​​is limited to Error limit applied PV of speed from (the actual speed of the vehicle at the time of the flash)
Speed ​​is limited to50 km/h Error limit applied5 km/h PV of speed from (the actual speed of the vehicle at the time of the flash)56 km/h (remaining 51 km/h)
Speed ​​is limited to90 km/h Error limit applied5 km/h PV of speed from (the actual speed of the vehicle at the time of the flash)96 km/h (remaining 91 km/h)
Speed ​​is limited to110 km / h Error limit applied5% PV of speed from (the actual speed of the vehicle at the time of the flash)116 km/h (remaining 111 km/h)
Speed ​​is limited to130 km / h Error limit applied5% PV of speed from (the actual speed of the vehicle at the time of the flash)137 km/h (remaining 131 km/h)
