204. Fatigue

Fatigue reduces concentration, reaction time, judgement and the ability to stay alert while driving. It can develop after long periods behind the wheel, insufficient sleep, illness, irregular working hours or driving at times when the body normally expects rest. Warning signs include frequent yawning, heavy eyelids, difficulty keeping a steady speed or lane position and forgetting parts of the journey. Drivers should stop and rest as soon as they notice signs of tiredness and should not rely on caffeine, fresh air or loud music as substitutes for sleep.

Why is fatigue dangerous when driving?

Fatigue can slow reaction time, reduce concentration and impair judgement, increasing the risk of missing hazards or losing control of the vehicle.

What are common signs of driver fatigue?

Warning signs include frequent yawning, heavy eyelids, difficulty concentrating, drifting within the lane and forgetting parts of the journey.

What is a microsleep?

A microsleep is a very brief episode of sleep that can last only a few seconds. During that time, the driver may be completely unaware of the road and unable to react.

What should you do if you feel tired while driving?

Stop at a safe place and rest before continuing. If possible, take a short nap or end the journey until you are sufficiently rested.

Does coffee remove driver fatigue?

Caffeine may temporarily improve alertness, but it does not replace adequate sleep. A tired driver should still stop and rest.

When is fatigue most likely to affect drivers?

Fatigue is more likely after long periods of driving, insufficient sleep, night driving or driving during normal sleeping hours.
