Lane departure warnings are safety features in vehicles designed to alert drivers when they unintentionally drift out of their designated lane. This system uses cameras and sensors to monitor lane markings on the road. If the vehicle begins to veer without signaling, the system activates an alert, which can be a sound, vibration, or visual warning. These warnings help prevent accidents caused by driver inattention or fatigue. Many modern vehicles come equipped with lane departure warning systems, contributing to overall road safety. Some advanced systems may also include lane keeping assist, which can gently steer the vehicle back into its lane.
