The main components of LKS are a camera, a processor and a control unit. The camera continuously films the road markings. The information is transmitted and handled by the control unit, which is connected to features such as the speedometer, braking signal and turn indicator. When a number of criteria are met that show that the truck is unintentionally steering off course, the control unit sends a warning signal.
The LKS is easily activated or de-activated via a switch on the instrument panel.
