Black box on new cars: what is it for?

Compulsory since May 1st on all new cars, the black box has a very specific role. Find out which one.

You have most likely heard of it, not without feeling some fear. And for good reason, this famous black box, which we have been hearing about for several years now and which many motorists fear, does indeed arrive in our cars. Until then seen as a kind of science fiction object, this device is however much less intrusive and frightening than one might think. We invite you to shed light on this new system, the implementation of which was voted in 2019 by the European Parliament. Coming into force on May 1, this measure then concerns all new cars, but also buses and trucks leaving the factory throughout Europe. But then what is this dreaded black box really for?

A black box in the event of an accident

Rest assured right away, the goal is not to track your every move in the car, or even to know how often you brake or accelerate, unlike some boxes provided by insurance companies. The purpose of this black box is simply to understand what happened in the event of an accident. A bit like for planes, except that this device is not equipped with microphones, and fortunately. Only the 30 seconds preceding the accident and the following 10 seconds are then kept. Several data are recorded, such as the speed, the force of the collision, the engine speed or the wearing of the seat belt.

Every 40 seconds, theregistration is overwritten. Only a handful of people will then be able to access the information collected, such as the judicial authorities or the investigation offices. Nevertheless, this system has limits, since it is impossible to know the exact context of an accident just with the recorded data.
