A driver-fatigue warning system (10) suitable for use in an automated vehicle (12) includes a camera (14), an alert-device (28), and a controller (32). The camera (14) renders an image (16) of a lane-marking (18) and of an object (22) proximate to a host-vehicle (12). The alert-device (28) is operable to alert an operator (30) of the host-vehicle (12) of driver-fatigue. The controller (32) is in communication with the camera (14) and the alert-device (28). The controller (32) determines a vehicle-offset (36) of the host-vehicle (12) relative to the lane-marking (18) based on the image (16). The controller (32) determines an offset- position (44) of the object (22) relative to the lane-marking (18) based on the image (16). The controller (32) determines that a lane-departure (38) has occurred when the vehicle-offset (36) is less than a deviation-threshold (40). The controller (32) does not count (42) occurrences of lane-departures (38) when the offset- position (44) is less than an offset-threshold (46), and activates the alert-device (28) when the count (42) of the occurrences of lane-departures (38) exceeds a crossing-threshold (48) indicative of driver-fatigue.
