Lane departure warnings: a signal rather than steering intervention

Useful to know

Lane departure warning uses a camera to monitor lane markings and the vehicle’s position. If an apparently unintentional departure is detected, it gives a visual, audible or tactile warning, depending on the implementation. [1]

A warning does not itself mean automatic corrective steering. Bosch also describes suppressing warnings when a turn signal indicates an intended movement. Check the actual behaviour of the vehicle rather than treating every lane function as identical. Marking condition and visibility affect recognition. Drivers should correct an obvious deviation without waiting for a warning.
