What is the correct course of action in this situation?

In this situation, you're approaching a curve with a warning sign indicating potential icy conditions. The correct actions are to reduce your speed and avoid abrupt steering movements.

Reducing speed allows for better control of the vehicle in slippery conditions. If the road is icy, a slower speed helps maintain traction and reduces the risk of losing control. Additionally, avoiding jerky steering movements prevents skidding or sliding, which can occur if the vehicle's tires lose grip on the surface.

Braking hard while already in a bend can lead to a loss of control, making it dangerous. Therefore, the combination of reducing speed and steering smoothly is crucial for safe navigation in such conditions, adhering to German traffic regulations promoting safe driving practices in potentially hazardous situations.
