The vertical danger and information signage warns of the possibility of the road surface being slippery due to rain, snow, or ice, expressly recommending speed moderation. Thus, given this warning, the driver must adjust the vehicle's speed to the road conditions and weather to ensure road safety. Increasing speed to perform a quick overtake contradicts the indication for moderation and increases the risk of skidding. On the other hand, stopping on the carriageway of a motorway or expressway due to fog is extremely dangerous and prohibited, and this is not the indication conveyed by the panel.
