In which of the following conditions should a rider avoid riding?

Riding in rain, snow, or icy conditions presents significant hazards that can severely impact a motorcyclist's ability to control their vehicle. These weather conditions reduce traction, making it difficult to maneuver and increasing the likelihood of skidding or losing control. Rain can create slippery road surfaces, while snow and ice can lead to extremely dangerous situations, including fishtailing and the inability to stop effectively. Furthermore, visibility is often compromised in poor weather, which can prevent riders from seeing obstacles or other vehicles. Therefore, it is prudent for riders to avoid these conditions to ensure their safety as well as the safety of others on the road.
