What does this traffic sign warn you of?

This traffic sign warns drivers of the danger of skidding on the road ahead. In German traffic rules, this sign indicates two main conditions under which skidding is likely:

1. When the roadway is dirty—such as covered with sand, gravel, or mud—which reduces tire grip.
2. When the roadway is wet from rain, snow, or ice, making it slippery and increasing the risk of losing control.

The sign does not relate to alcohol consumption or drivers under the influence; rather, it focuses on road surface conditions that can cause skidding. When you see this sign, you should reduce speed, avoid sudden steering or braking, and drive carefully to maintain control. Remembering this helps you anticipate and react to hazardous road conditions effectively in Germany.
