What type of weather condition requires a driver to be particularly vigilant of pedestrians and cyclists?

Snowy or icy conditions present significant challenges for drivers, making it essential for them to be particularly vigilant regarding pedestrians and cyclists. During these weather conditions, visibility can be reduced due to falling snow, and surfaces may become slippery, which affects the ability of both cyclists and pedestrians to navigate the roads safely.

Additionally, pedestrians may step into the road more frequently in snowy weather as they avoid snowbanks or other obstacles, while cyclists might struggle with balance on slick surfaces. It is essential for drivers to slow down, increase their following distance, and be extra cautious at intersections and near bus stops or crosswalks, where pedestrians and cyclists are likely to be present.

While each of the other weather conditions can pose risks—for example, rainy days can cause visibility issues and require careful handling of hydroplaning—snowy and icy conditions particularly exacerbate those risks due to their impact on traction and the behavior of both drivers and vulnerable road users.
