Eisglätte

Eisglätte refers to a dangerous road condition that occurs when a thin, often transparent layer of ice forms on road surfaces. This phenomenon is typically caused by freezing rain, where raindrops freeze upon contact with surfaces that are below freezing point. It can also result from melting snow or frost that refreezes overnight.

The primary danger of Eisglätte lies in its extreme slipperiness. The ice layer is often so thin and clear that it is difficult to see, making it hard for drivers to anticipate and react to the hazardous conditions. Braking distances are significantly increased, and even minor steering adjustments can lead to a loss of control.

Eisglätte is most common during winter months when temperatures hover around freezing point. It can occur unexpectedly, even when the air temperature is slightly above zero, if the road surface itself is colder. This condition poses a serious risk of traffic accidents, including skidding, collisions, and vehicles leaving the road.

Authorities typically issue warnings for Eisglätte, advising drivers to reduce speed, maintain increased following distances, and avoid sudden movements. Special tires designed for winter conditions can offer some improved traction, but even with these, caution is paramount. Pedestrians are also at risk of slipping and falling.
