Lane-keeping assist is a safety feature found in many modern vehicles that helps drivers stay within their designated lane on the road. Using cameras and sensors, the system detects lane markings and provides gentle steering assistance to prevent unintentional lane departures. If the vehicle begins to drift out of its lane without signaling, lane-keeping assist can automatically adjust the steering to guide the car back into the center of the lane. This technology enhances driving safety, especially on long trips or during moments of distraction.
