The German Weather Service (DWD) issued warnings for hazardous road conditions after early winter snowfall in Berlin and Brandenburg caused accidents and traffic congestion, with up to three centimeters of snow reported near the Oder River.Severe multi-vehicle accidents on the A93 near Maxhütte-Haidhof and A81 near Geisingen resulted in four deaths and multiple injuries, while schools and bus operations faced disruptions in several regions.Reports from Hesse, Lower Saxony, Hamburg, Schleswig-Holstein, and other states described dozens of ice-related accidents, prolonged road closures, and suspended transport services as the wintry weather persisted.
