Where is black ice likely to occur on the road?

Black ice is particularly likely to form in sheltered or shaded areas due to the lack of direct sunlight and limited exposure to warmer elements. These areas can retain moisture, which can freeze more readily when temperatures drop, creating a invisible layer of ice on the road. Drivers may not see this ice, as it is often transparent and blends in with the road surface, making it very dangerous.

In contrast, sunny days reduce the likelihood of ice forming on the road, as the sun warms the pavement, even in cold temperatures. High-speed roads have higher traffic volumes and are often maintained better, leading to less ice accumulation. Well-lit areas are similarly less prone to black ice, as artificial lighting can help maintain temperatures, keeping roads warmer against freezing conditions. Understanding these conditions can help drivers stay vigilant and reduce the risk of accidents associated with black ice.
