When should a motorcycle rider wear protective clothing?

Wearing protective clothing is essential for motorcycle riders to minimize the risk of injury in the event of an accident. This clothing is designed to provide a barrier against abrasions, impacts, and other potential hazards regardless of weather conditions. While it is true that protective clothing is especially important during adverse conditions like rain or at night when visibility is reduced, it should be worn on all rides to ensure the highest level of safety.

Specific to the scenario of riding in the rain or at night, protective clothing can help maintain visibility and increase the rider's comfort and safety by providing better grip and insulation against the elements. The other options suggest limitations to when protective clothing should be worn, which could lead to increased risk during those times when many accidents occur. Therefore, wearing protective clothing at all times while riding is considered best practice for safety.
