Do I get flashed by a speed camera if I drive 135 km/h on the motorway?

In France, radars, fixed and mobile, act a priori according to a margin of error. In other words, they are theoretically unlikely to be hit with a speeding ticket for insignificant speeding…

You may be driving or driving at the speed limit, so-called speeding can happen to anyone. Driving in the city at 52 km/h instead of 50, at 132 km/h on the highway, almost no one is immune. These “small” speeding offenses are also currently the subject of real reflection by the French executive, which is considering it no longer punishes them with a deduction of points on their driving licenceas it happens today

Incorrect name

You should also know that, on our roads and motorways, driving at an actual speed very slightly above an authorized speed cannot trigger a speed camera. In fact, in France the radars, whether mobile, on board or not, or fixed, are calibrated with a margin of error, also wrongly called a margin of tolerance.

Fixed or embedded, not the same margin

In other words, each speed camera is only supposed to activate once the margin of error has been taken into account, this is called retained speed. For example, since this is the example we are interested in here, when driving at 135 km/h on a road limited to 130 km/h, a fixed radar will not be activated, which acts in these cases with a margin of error of 5%. And probably even less if it is a mobile radar on board since at this speed of 130 km/h it still promises a margin of error of 10%.
