What are some signs of fatigue while driving?

Fatigue is a serious issue that can significantly impair a driver's ability to operate a vehicle safely. Frequent yawning, heavy eyelids, and drifting from the lane are common signs that a driver may be experiencing drowsiness or fatigue.

Yawning is often an involuntary response to the body's need for rest, indicating that the driver is feeling tired. Heavy eyelids signal that the driver is struggling to keep their eyes open, which is a clear warning sign of impending sleepiness. Drifting from the lane can occur if a driver’s attention wanes or if they momentarily doze off, making it difficult to maintain control of the vehicle.

Recognizing these signs is crucial for preventing accidents. Addressing fatigue by taking breaks, switching drivers, or finding a safe place to rest can greatly improve road safety. The other options, while they may reflect distraction or different driving behaviors, do not specifically indicate fatigue and therefore do not serve as helpful indicators for recognizing diminished alertness.
