Lane-keeping assistance 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 alerts if the vehicle begins to drift without signaling. This can help prevent accidents caused by unintentional lane changes. In some systems, lane-keeping assistance can also provide gentle steering inputs to guide the car back into the lane. This technology is particularly useful on long drives or during times of fatigue, enhancing overall driving safety and comfort.
