What does this traffic sign indicate?

This traffic sign indicates potentially hazardous conditions due to winter weather. Specifically, it signifies two main issues: icy conditions and packed snow on the road.

Understanding these two aspects is crucial for safe driving. Icy conditions can lead to loss of traction, significantly increasing the risk of accidents. Packed snow can also create slippery surfaces that may not be immediately evident, making it essential for drivers to reduce speed and maintain greater following distances.

In Germany, recognizing these conditions helps in adjusting driving behavior accordingly, ensuring safety for all road users. Always heed such warnings and drive cautiously in adverse weather.
