What should riders avoid while riding in relation to other vehicles?

Answer: C — Riding in blind spots

Riders should avoid riding in blind spots because this significantly increases the risk of being unseen by drivers of other vehicles. Blind spots are areas around a vehicle that are not visible to the driver through mirrors. If a rider is positioned in a blind spot, the likelihood of being involved in a collision heightens, especially during lane changes or turns when an adjacent driver may not have a clear view of the motorcycle. Riding in such areas can lead to dangerous situations where the rider might not have enough time to react if the vehicle changes lanes or merges. Maintaining visibility is crucial for safety while riding. By keeping out of blind spots, riders can enhance their own visibility and awareness of surrounding traffic, contributing to a safer riding experience overall.
