What does the Lane Departure Warning System do?

The Lane Departure Warning System is designed to enhance safety by monitoring a vehicle's position relative to the lane markings on the road. When the system detects that the vehicle is unintentionally drifting out of its designated lane without the use of turn signals, it provides an alert to the driver. This alert can come in various forms, such as visual warnings on the dashboard, audible sounds, or even steering wheel vibrations. The main objective of this system is to help drivers maintain their lane, reducing the risk of accidents caused by drifting, which can occur due to distractions, fatigue, or other factors.

The other choices involve functions that are unrelated to lane positioning and departure warning. For instance, regulating engine temperature pertains to vehicle performance, while automatic braking is related to collision avoidance systems. Adjusting mirrors affects visibility but does not play a role in lane monitoring. Therefore, tracking a vehicle's position within a lane is the primary function of the Lane Departure Warning System, emphasizing its role in promoting safer driving practices.
