Which of the following is NOT a sign of driver fatigue?

Sudden bursts of energy can sometimes occur as a reaction to fatigue, where a driver may feel a temporary increase in alertness. However, this is misleading because true driver fatigue typically leads to a decrease in overall performance and attentiveness. The presence of sudden bursts of energy might create a false sense of confidence, but it does not accurately represent fatigue itself.

In contrast, feeling drowsy, daydreaming, and accidentally drifting into other lanes are all clear indicators of fatigue. Drowsiness is a direct symptom of being overly tired, daydreaming is often a result of a wandering mind when a driver is struggling to stay awake, and drifting into other lanes is a dangerous manifestation of reduced attention, which is often associated with driver fatigue. Understanding these signs is crucial for recognizing when a driver needs to take a break to ensure safety on the road.
