What is a sign that you might be too fatigued to ride safely?

Being aware that your decision-making is slowed is an important sign that you might be too fatigued to ride safely. Fatigue can significantly impair cognitive functions, affecting how well you process information and react to the dynamic environment of the road. When you're fatigued, it may take longer for you to make critical decisions, such as responding to a potential hazard or choosing the appropriate speed for a turn. This delay can increase the risk of accidents, as timely decisions are vital for safe riding.

In contrast, the other options do not signify fatigue. Feeling overly energetic would indicate that you are likely alert and ready to ride. Increased awareness of your surroundings suggests that your focus and attentiveness are heightened, which is the opposite of being fatigued. Enhanced reflexes and responses similarly imply that you are functioning well and able to react quickly, rather than experiencing the sluggishness that comes with exhaustion. Therefore, recognizing slowed decision-making as a sign of fatigue is crucial for maintaining safety while riding.
