What does this traffic sign warn you of?

This traffic sign indicates a risk of skidding. It specifically warns drivers about potentially slippery conditions on the road.

1. **Danger of skidding when the roadway is dirty**: This could occur due to debris like mud, oil, or other materials on the surface, which can reduce tire traction.

2. **Danger of skidding when the roadway is wet**: Rain, snow, or ice can create slick surfaces, increasing the likelihood of losing control of the vehicle.

The sign does not indicate anything about alcohol influence; its primary focus is on road conditions that can lead to skidding. Understanding this alert is crucial for drivers to adjust their speed and driving behavior to enhance safety in potentially hazardous conditions.
