Lane Departure Warning is a safety feature in modern vehicles designed to help prevent accidents caused by unintentional lane drifting. It uses cameras and sensors to monitor the car's position within the road lanes. If the vehicle begins to stray from its lane without signaling, the system alerts the driver with visual or audible warnings. This technology is particularly useful during long drives or in situations where the driver may become distracted or fatigued. By providing timely alerts, Lane Departure Warning helps ensure that drivers stay aware of their surroundings and maintain better control of their vehicle, enhancing overall road safety.
