Group 1 - The current cold wave has led to significant snowfall and a drop in temperatures, increasing road safety hazards [1] - The nature of the snow, rather than its thickness, is the key factor determining road safety [4][6] - In northern regions, dry and fluffy snow forms, providing better friction on roads, while in southern regions, wet snow can compact into a slippery ice mixture, posing greater risks [4][9] Group 2 - Northern areas may experience "blowing snow," which can reduce visibility and obstruct roads, while southern regions face challenges from smooth ice layers formed by repeated thawing and freezing [9] - "Black ice," a thin layer of transparent ice that forms under low temperatures, is particularly dangerous as it significantly reduces tire friction [11] - Meteorological forecasts indicate ongoing freezing rain and ice pellet weather in regions like Guizhou, Guangxi, and Jiangxi, urging the public to stay updated on weather and road conditions [13]
