What must you be prepared for when you pass these traffic signs?

This traffic sign indicates that specific precautions are necessary for conditions related to winter sports. The first warning is about the possibility that the road may be used for winter sports activities, which alters standard traffic patterns and increases the presence of pedestrians engaging in these activities.

The second aspect to be vigilant about is the potential presence of packed snow or black ice on the roadway. This surface condition significantly affects vehicle traction and can lead to dangerous driving situations.

Choosing both these elements is crucial because drivers must be aware that their surroundings can change dramatically due to winter activities and hazardous road conditions. Understanding these risks allows drivers to adjust their speed and driving behavior accordingly to ensure safety for everyone on the road.
