What should a rider do if they feel fatigued while riding?

Answer: B — Stop and take a break

A rider who feels fatigued while riding should stop and take a break. Riding a motorcycle requires full concentration, physical control, and quick reflexes. When a rider is fatigued, their ability to respond to unforeseen circumstances diminishes significantly, increasing the risk of accidents. Taking a break allows the rider to rest, hydrate, and regain alertness. This is essential for ensuring both their safety and the safety of others on the road. Continuing to ride while fatigued can lead to reduced reaction times and impaired judgment, which is why the other options are not advisable. Pushing through fatigue can create a dangerous situation, as can speeding up to reach a destination quickly—both actions could compromise a rider's safety. Moreover, switching routes does not address the underlying issue of fatigue; resting is the only effective solution in this situation.
