How can you tell if a road is icy?

The visibility of frost and a sheen on the road surface indicates ice because when temperatures drop, moisture in the air can condense and freeze on the road, creating a glossy overlay. This sheen makes it difficult for drivers to recognize the presence of ice, which is why caution is essential, especially on bridges, overpasses, and shaded areas that may not thaw easily. In addition to looking for a shiny or glassy appearance, you may also observe frost on vehicles or the ground, which can suggest that roads are slippery and potentially hazardous. This awareness is critical for safe driving during cold conditions.
