Overview
- Katwarn reports sudden freezing rain creating black ice, and the German Weather Service has declared Warnstufe rot for several districts today.
- Black ice forms rapidly on ice‑cold surfaces, is hard to detect in dusk or darkness, and is especially likely on bridges, shaded stretches, and roads near water or forests.
- Under the StVO, winter tires are mandatory in such conditions, with fines of 60–80 euros and potential insurance reductions for violations or crashes.
- Drivers are advised to slow down, increase following distance, brake and steer gently, pause travel during freezing rain, carry winter gear, and remember that ABS, ESP and all‑wheel drive cannot overcome physics; TÜV Süd and GTÜ recommend practicing winter handling or taking training.
- Cyclists may use the roadway if a mandatory bike path is uncleared per a 2003 Federal Court ruling, and the ADFC advises lower tire pressure, spike tires where appropriate, a lowered saddle, using both brakes gently, strong lighting and reflective clothing.
