Speed ​​cameras detecting who slows down and then accelerates

Speed ​​cameras that detect who brakes and then accelerates are not entirely new in Spain. In 2020 we spoke here on this subject and sparked a lively discussion.

In practice, this new system is able to detect which drivers have suddenly slowed down.

Radar Cascade in Spain: Mobile cinematograph installed

In neighboring Spain, speed cameras are being tested that detect who slows down and then accelerates when passing a speed camera.

The system in Spain is known as "cascading radars" and consists of placing a mobile cinemeter (mobile radar) behind a fixed radar to determine the speed of intruders. Whenever a driver tries to “cheat” the stationary camera, the mobile camera will attempt to record the speed and then issue a ticket to the violator.

The case is not new and the Spanish authorities are already testing the system. The new radars may penalize drivers for "braking" rather than "speeding".

Mobile radars being tested in Spain have an error of 7 km/h on roads with a maximum speed of less than 100 km/h. Therefore, the radar will detect a violation from 58 km/h, in a zone limited to 50 km/h. If the maximum speed exceeds 100 km/h, a surcharge of 7% applies. Thus, all vehicles that drive faster than 117.7 km/h on the 110 km/h road will also receive a corresponding fine.

Lawyer Remy Jossom, an expert in automotive law, told The Connexion that he thinks it is unlikely that the new cameras, unlike in Spain, will be introduced in some countries, such as France. “How to write a law so that no one breaks the law?

In Portugal, the focus is on medium speed cameras. Instant speed cameras are nothing new for drivers on Portuguese roads. As for the radars that determine whether vehicles were moving faster than allowed on a path, there are already 10 of them in Portugal.
