#Ice driver terminology drivers
It is therefore important for drivers to be conscious of the geography over which their vehicle is travelling. Low-lying areas:Ĭold air is heavier than warm air thus, depressions in the land, low-lying areas and swamps or marshlands are going to be colder than the land at higher elevations. Know that there is likely ice, and use the same technique as going over a bridge. The same technique is used when going under overpasses. The cold air surrounds the structure and any moisture on the road surface freezes faster, because none of the warm air from the daytime is contained.Ĭonsequently, when going across bridges, let off the throttle and allow the vehicle to freewheel. On the other hand, a roadway with less traffic or no traffic at all and is low-lying or in the shadow of a mountain or hill is more likely to have ice.
Likewise, roadways that have a lot of traffic causing the water to be moved around and displaced by the vehicle tires is less likely to have ice. Moving water will not freeze, unless exposed to tremendous cold. Yet, there will be a layer of ice on the top of mud puddles in the morning after a cool autumn night.Īs well, a lake-still water that is often only moved by the wind-will freeze before a river. This condensation is caused by hot air coming into contact with the cold glass.Īs hot air holds more moisture than cold, the water vapor becomes a liquid when cooled causing condensation (water droplets) on the outside of the glass.Īnd a thin sheen of water is going to freeze faster than a large pool of water.Ī lake, for example, requires long exposure to subzero temperatures before it freezes. Over a short period of exposure on a hot summer day, a drink with ice cubes in it will form moisture on the outside of the glass. This moisture or sheen of water is going to freeze when the night temperature falls below 5☌.Ĭonsequently, there will most likely be ice on less-travelled roads by early morning.
In other words, drivers know when there is ice on the road.Īny geographical area that allows the air around a roadway to cool is going to have moisture. “ In other words, the term “black ice” allows bad drivers to shun the responsibility of their actions.īlack Ice” like the word “accident” does little more than abdicate motorists from the responsibility of their poor or ignorant driving habits.Īnd just because an event is unforeseen, doesn’t mean that its not foreseeable. Just because motorists can’t see the ice doesn’t mean it’s not there.
