什么是黑冰?? 注意这个冬季的道路危险

Thousands of injuries and fatalities occur every year from accidents on snowy or icy roads, 根据 联邦公路管理局. Many drivers are unaware of a common culprit in many of these crashes — 黑冰. 那么，什么是黑冰? It is a transparent glaze that forms without bubbles, allowing it to easily blend into the surface of the roads.

Black ice is most likely to form when t在这里 is a sudden temperature drop, such as in the early morning and evening hours. Common problem areas include bridges, overpasses and shaded areas of the road. These areas have much colder surfaces that rapidly freeze when air moisture makes contact — especially if they're near lakes or rivers.
