Distraction, fatigue and road rage →Notice the change before a lane departure
Looking forward is necessary, but a fixed stare is different from actively checking the driving scene. SGI describes a shrinking forward search and reduced eye movement as an early sign of tiredness. A straight, repetitive road can make sleepiness especially dangerous.
A driver who is still holding a steady speed may nevertheless be losing attention. Ask whether you are continuing to search for developing hazards, rather than using lane position alone as proof that you are alert.
Source: SGI — Other impairing factors ↗Choose rest or another driver
SGI’s practical response is to admit that fatigue has developed, stop and rest, or change drivers when tiredness starts. Reaching a planned destination is not a reason to postpone that decision. The warning concerns your ability to drive, even when the road appears quiet.
Arrange a safe place to stop. Changing drivers only helps when another driver is able to take over safely and lawfully; this reference does not remove learner-supervision requirements.

Original learning cases
Your gaze stays fixed on the car ahead and you stop checking farther along the road. The SGI warning is already present, even though you have not drifted out of your lane.
A rumble strip vibrates after a long, monotonous drive. Correcting the lane position alone leaves the tiredness unresolved; arrange a safe stop.
A trip has only a short distance left, but you cannot stay awake. The remaining distance does not override the handbook’s direction to get off the road.
Understand what a rumble strip can do
Rumble strips can alert a driver who drifts toward a shoulder or centre line. That warning does not remove fatigue. Treat it as a reason to reconsider continuing, rather than as a system that will keep you awake for the rest of the trip.
Use the free exercises to distinguish a warning sign from a remedy. This page does not prescribe a fixed rest period or promise that a particular break makes every driver safe to resume.
