How can a driver monitor their fatigue levels?

Monitoring fatigue levels is crucial for maintaining safety while driving, especially for commercial drivers. Taking regular breaks and self-assessing concentration is an effective strategy for managing fatigue. Regular breaks allow the driver to rest both mentally and physically and can help to rejuvenate focus and alertness. Additionally, self-assessing concentration helps the driver recognize when they may be becoming fatigued, enabling them to take action before it impacts their driving ability.

In contrast, relying on increased caffeine intake may provide only a temporary boost and can lead to a crash in energy levels later on. Listening to loud music may help keep someone alert for a short duration, but it does not address the fundamental issue of fatigue and can actually be distracting. Changing lanes frequently could lead to increased fatigue due to the added stress of constant maneuvering and does not necessarily improve alertness. Thus, taking breaks and self-assessment stands out as the most practical and effective method for monitoring fatigue.
