What is the function of the warning from a fatigue or drowsiness detection ADAS?

Correct answer

Warn to encourage a safe stop and rest.

Warn of signs of fatigue or drowsiness so the driver can stop safely and rest. Detection depends on the system; not every system tracks eye movement or detects every case. The warning does not replace rest or permit continuing when unfit. Other assistance systems may intervene, but the fatigue warning alone must not be treated as steering control or an automatic stop.
