Snowy roads occur when precipitation falls as snow and accumulates on the surface of the road. This can create hazardous driving conditions, as the snow can reduce traction for vehicles, making it difficult to steer and stop. Snowy roads are often treated with salt or sand to improve safety and enhance vehicle grip. In regions where winter weather is common, such as the northern United States or Canada, snowy roads are a regular occurrence. Local authorities typically monitor weather conditions and may issue warnings or advisories to inform drivers about potential dangers associated with traveling on snowy surfaces.
