Even if most of the road appears free from ice, where might you still find patches?

Patches of ice are often found on bridges due to their structural characteristics. Bridges are exposed to air both above and below, which allows cold temperatures to affect them more directly than the surrounding roads. This can lead to freezing conditions even when the pavement of the road appears clear. Unlike regular roads that retain heat from the ground, bridges cool down quicker. Therefore, the presence of ice can occur even if the surrounding road surfaces seem to be safe for travel. That's why it's vital for motorcyclists and other drivers to be cautious when crossing bridges during cold weather, as they are more susceptible to icy conditions compared to other parts of the roadway.
