Yes. In most modern vehicles, ADAS calibration is required after replacing the windscreen.
Vehicles manufactured after 2015 commonly have Advanced Driver Assistance Systems (ADAS) that rely on a forward-facing camera mounted behind the windscreen.
When the windscreen is removed and replaced, the camera alignment changes slightly, even when installed correctly.
Without re calibration, safety systems may become inaccurate.
These systems include:
• Automatic Emergency Braking (AEB)
• Lane Departure Warning
• Lane Keep Assist
• Adaptive Cruise Control
• Forward Collision Warning
• Traffic Sign Recognition
Even a small change in camera angle can affect how these systems interpret the road.
For this reason, most manufacturers require ADAS re calibration after windscreen replacement.
What Happens If ADAS Is Not Re calibrated?
If ADAS calibration is skipped after windscreen replacement, the system may:
• Misjudge distances to other vehicles
• Trigger emergency braking incorrectly
• Fail to detect lane markings accurately
• Disable driver assistance features
• Display warning lights or system faults
This is why professional windscreen replacement should always include ADAS calibration where required.
How ADAS Calibration Works
ADAS calibration ensures the vehicle’s forward camera and sensors are aligned to manufacturer specifications.
There are two main procedures:
Static Calibration
Performed in a controlled workshop environment using diagnostic software and calibration targets.
Dynamic Calibration
Performed while driving so the vehicle can relearn road markings and distances.
Many vehicles require both processes.
Professional calibration equipment is required to ensure correct camera alignment and system accuracy.

Frequently Asked Questions (ADAS Calibration)
Do all cars need ADAS calibration after a windscreen replacement?
Not all vehicles require calibration, but most vehicles manufactured after 2015 do, especially if they have a camera mounted behind the windscreen.
How long does ADAS calibration take?
Calibration typically takes 30–90 minutes, depending on the vehicle manufacturer and calibration method required.
Can I drive without ADAS calibration after replacing the windscreen?
You may be able to drive the vehicle, but driver assistance systems may not function correctly, which could affect safety features such as emergency braking and lane assist.
How do I know if my vehicle has ADAS?
Common signs include:
• Lane assist
• Automatic emergency braking
• Adaptive cruise control
• Collision warning alerts
These features indicate the vehicle likely has ADAS camera systems mounted to the windscreen.
