No more confusion, these are the speed camera error margins

Radar section signal

The best trick not to be fined for speed cameras, whether they are fixed, static mobile, mobile on a vehicle or stretch, is to circulate without exceeding the legal maximum. But of course, if we want to speed up a bit, it is interesting to know that the radars They do not fine as soon as we go over 1 km/h, but they do have certain margins. And what are those margins?

The first thing to note is that many recent rumors have said that these margins had changed. However, the last modification of this regulation appeared in the BOE number 47, from February 24, 2020. Therefore, no, the margins of the speed cameras have not changed in the last days or weeks. Let's review what those margins are.

As published in the aforementioned BOE, there are several maximum permissible errors. First of all, in the conformity assessment phase of the “tools” there are margins. While in the periodic checks, when they are already frequently used and periodic reviews are carried out, are different.

What we as citizens and drivers are most interested in are the margins allowed in the periodic verification. But within this branch we find two more ramifications; which are tests in laboratories with simulations and tests on the road with real traffic. The data that interests us is that of real road traffic.

This document contains the margins for kinemometers, which are conventional radars, either work in a fixed station, a mobile installation or an aircraft kinemometer.

  • In a kinemometer in fixed or static installation the margin is 5 km/h at speeds up to 100 km/h and 5% for speeds above 100 km/h.
  • Meanwhile, in a kinemometer in mobile installation on vehicle the margin is 7 km/h up to 100 km/h and 7% for speeds above 100 km/h.
  • Meanwhile, one kinemometer on aircraft It has a margin of 5% for the measurement of speed, and there are also margins for distances.

How much can we circulate according to so that a radar does not fine us

100 km/h 105 km/h 107 km/h
110 km/h 115.5 km/h 117.7 km/h
120 km/h 126 km/h 128.4 km/h

What are the penalties for speeding?

speeding fine

Since we have talked about speed cameras and margins, it is not a bad time to review the penalties for speeding. In the case of highways and motorways limited to 120 km/h, the fine is 100 euros if we drive between 121 and 150 km/h, 300 euros and 2 points if we drive between 151 and 170 km/h, 400 euros and 4 points if we go at speeds between 171 and 180 km/h h, 500 euros and 6 points between 181 and 190. From 191 km/h are 600 euros and 6 points, considering a very serious offense.

We recall that there are currently around 780 fixed radars, stretch 92 and about 1.300 mobile speed camera locations, although the latter must be taken with tweezers since they can place a mobile radar with a fixed station practically wherever they want.
