Can replacing a windscreen affect a car’s driver-assistance cameras?

<p><strong>Yes. Some cars require camera or sensor calibration after windscreen replacement to maintain correct driver-assistance operation.</strong></p><h2>Why this matters</h2><p>Forward cameras used for lane assistance or emergency braking may be mounted to the glass. Even small changes in position or optical characteristics can affect interpretation of road markings and objects. Not every vehicle requires the same calibration procedure, and a warning-free dashboard does not necessarily prove it was completed correctly.</p><h2>What to do in practice</h2><p>Ask the glass repairer whether the exact model needs static or dynamic calibration and request a record of the work. Confirm any manufacturer-approved glass requirements and road-test instructions. When buying a car with recent glass replacement, seek evidence of proper calibration.</p><h2>Important distinction</h2><p>Driver-assistance systems do not replace driver attention or guaranteed collision avoidance.</p>
