What is the correct course of action in this situation?

In the given situation, you're dealing with a winding road and a warning sign for potential icy conditions.

When approaching this kind of scenario, reducing your speed is crucial. Icy patches can significantly decrease tire grip, making it essential to slow down to maintain control. Also, avoiding jerky steering movements is important; abrupt changes in direction can lead to loss of control, especially on slippery surfaces.

Braking hard while in a bend can cause the vehicle to skid, making it dangerous. Therefore, the correct actions—reducing speed and steering smoothly—align with German traffic rules aimed at promoting safe driving in challenging conditions. Always prioritize stability and control over speed in such cases.
