What is ADAS, and why are these systems changing road safety?

More and more newer vehicles are equipped with technologies capable of anticipating hazards, correcting a vehicle’s path, or braking automatically. These technologies are known as ADAS, which stands for Advanced Driver Assistance Systems.

What exactly is ADAS?

ADAS is not a single device, but a set of cameras, radars, and sensors installed in various locations on the vehicle—often behind the windshield, in the bumper, or on the side mirrors.
These components continuously collect information about the car’s surroundings (other vehicles, pedestrians, road markings, traffic signs) and transmit it to an onboard computer, which decides whether to alert the driver or intervene directly in the driving process.

The Main ADAS Features in Newer Vehicles

Depending on the vehicle’s model and year, ADAS may include several features, such as:

Why do these systems need to be recalibrated ?

All ADAS functions rely on the precise alignment of cameras and sensors relative to the vehicle’s axis. A windshield replacement, even a minor collision, or a simple suspension adjustment can be enough to shift this alignment by a few millimeters—a deviation invisible to the naked eye, but sufficient to skew the distance or trajectory measurements used by the system.
That is why recalibration is recommended after such work, to ensure that the sensors continue to operate according to the manufacturer’s specifications.

In Summary

ADAS is gradually transforming the way we drive by adding a layer of electronic vigilance to that of the driver. However, this technology is only reliable if it is properly calibrated after any work is performed on the vehicle.
