Wet Pavement
Most weather-related crashes in the U.S. happen on wet pavement and during rainfall. Specifically, 74% occur on wet pavement and 46% during rainfall. About 17% occur during snow or sleet, 12% on icy pavement, and 14% take place on snowy or slushy pavement. Only 3% happen in the presence of fog. (U.S. Department of Transportation)
