Lane Departure Alert is a safety feature found in many modern vehicles. It uses cameras and sensors to monitor the car's position within its lane on the road. If the system detects that the vehicle is unintentionally drifting out of its lane without signaling, it provides visual or audible alerts to the driver. This technology aims to enhance road safety by helping drivers stay aware of their lane position. Some systems may also include Lane Keeping Assist, which can gently steer the vehicle back into the lane if necessary, further reducing the risk of accidents caused by lane departure.
