What best describes the role of Lane Departure Systems in modern vehicles?

Lane Departure Systems play a crucial role in enhancing vehicle safety by actively monitoring the vehicle's position within its lane. This technology employs cameras and sensors to detect when a vehicle unintentionally drifts out of its lane, a situation that can often lead to accidents if the driver is not vigilant. When drift is detected, the system may provide visual or audible alerts to the driver to regain control and return to the correct lane. In some advanced systems, Lane Departure Systems can also take corrective actions, such as steering the vehicle back into its lane if the driver does not respond to the alerts.

This functionality directly contributes to accident prevention and promotes safer driving practices, making it a vital component of modern driver assistance technologies. Other options, while related to vehicle functions, do not encapsulate the primary purpose of Lane Departure Systems, which focuses specifically on lane monitoring and corrective measures.
