What is a common effect of riding fatigue on a motorcycle rider?

Answer: B — Decreased reaction times and awareness

Riding fatigue has a significant impact on a rider's performance and safety. When a rider experiences fatigue, their physical and mental capabilities are diminished, leading to decreased reaction times and impaired awareness. This means that spotting potential hazards, responding to sudden changes in traffic, or making quick decisions becomes much harder, increasing the risk of accidents. Fatigue can impair cognitive functions such as judgment and concentration, making it difficult for the rider to process information quickly. Thus, it’s crucial for motorcyclists to recognize the signs of fatigue and address them appropriately to ensure safety on the road.
