Roads freeze quickly when they are:

Dry.
Narrow.
In the shade.
Used frequently.
Explanation

When temperatures drop very low, and it rains or snows, road sections shaded by trees or buildings are most likely to freeze quickly. These spots receive less sunlight, keeping the road surface colder than areas exposed to direct sunlight. This can be especially hazardous on curves and bridges, where shade and wind can create icy patches even if the rest of the road appears clear. Always exercise caution and be prepared to react appropriately if your tires begin to skid.
