- ☀️ Sunshine heats road surfaces to just above freezing, causing existing ice to turn into slush.
- 🚗 Traffic friction further churns this slush, especially as more vehicles use the roads.
- ❄️ The critical step is the refreeze, which can happen overnight or even when a section of road is unused for a period.
The Resulting Road Surface
- 🧩 This refreezing process creates a distinct cobblestone ice pattern on the roadways.
- ⚠️ The surface becomes drastically uneven, impacting vehicle stability, as seen with a lopsided truck.
Dangers and Precautions
- ⚠️ Cobblestone ice is dangerous due to the uneven surface it creates.
- ⚠️ While not expected to be widespread, patches can form, requiring drivers to use extra caution.
- ⚠️ The formation requires a thaw followed by a refreeze event.
