Windshield replacement is one of the most common services in the automotive industry. It's also one of the most commonly mishandled when it comes to ADAS. Nearly every vehicle built since 2018 has at least one camera mounted to the windshield -typically a forward-facing camera that powers lane departure warning, automatic emergency braking, and adaptive cruise control. When the glass comes out, so does the camera mount. And when the camera mount moves even slightly, the calibration is gone.
Why Removing the Glass Matters So Much
The forward-facing camera is calibrated to see the road from a very specific angle, at a very specific height, aligned precisely with the vehicle's centerline. The camera bracket is bonded to the windshield during manufacturing. When the glass is replaced, even if the new bracket is installed in the identical position, the camera's field of view has effectively been reset. OEMs universally require recalibration after windshield replacement on camera-equipped vehicles -no exceptions.
The AGRSS Standard and Your Liability
The Auto Glass Replacement Safety Standards (AGRSS) now include language about ADAS recalibration as part of proper glass replacement. Glass shops that skip recalibration are exposing themselves -and the vehicle owners -to liability. Collision shops that send vehicles to glass shops without requiring recalibration before delivery are equally exposed. The standard of care is clear: replace the glass, recalibrate the camera.
What Calibration After Windshield Replacement Looks Like
Most windshield camera calibrations are static procedures, performed with a target placed at a specific distance and height in front of the vehicle on a level surface. The OEM software guides the process and confirms when calibration is complete. In some vehicles, a dynamic component is also required -a drive at highway speeds to allow the system to verify its alignment against real-world lane markings. The entire process typically takes 45 minutes to an hour.
The Bottom Line
If your shop handles windshield replacements -directly or by referral -and ADAS recalibration isn't part of your standard process, you're leaving both revenue and legal protection on the table. Every camera-equipped vehicle that gets new glass needs a calibration. Every time. That's not a recommendation. It's the OEM requirement.
