Fog and twilight create a similar problem: the motorcycle silhouette becomes smaller and less contrasted. Other drivers notice large vehicles and bright lights first, while a motorcycle can blend into the background.
In these conditions, it is not enough to be visible; the rider also needs to be predictable. Sudden lane changes or sharp acceleration reduce the time other road users have to read the motorcycle position correctly.
More distance has two benefits. It increases reaction time and helps the rider stay where the motorcycle is not hidden by the vehicle ahead or by a larger truck.
The practical recipe is straightforward: checked lights, a clean visor, reflective details, and smooth movement. The fewer surprises a rider creates, the safer riding becomes when visibility is less than ideal.
