What is a common hazard for motorcyclists when riding at night?

Reduced depth perception is a common hazard for motorcyclists when riding at night due to the limitations of visibility in low-light conditions. Nighttime riding challenges a rider's ability to accurately judge distances and the size of obstacles on the road. This reduction in depth perception can make it difficult to assess how far away other vehicles are, how close they are to the rider, and how fast they are approaching.

When riding in the dark, the lack of sufficient light can obscure road features, making it hard to distinguish between various elements in the environment, such as curbs, potholes, or pedestrians. Motorcycles, which are already less stable than cars at lower speeds, can become even more precarious when the rider cannot accurately perceive the spatial relationship to other objects and navigation points.

In contrast to the correct choice, increased visibility, less traffic, and more road signs may not accurately reflect the reality of nighttime riding. Visibility is generally reduced at night, traffic patterns can vary widely depending on location and time, and while there may be signs present, they may be less visible due to low light, further complicating the ride for motorcyclists.
