  • Packed snow: less than 4 cm, road temperature of < 0 degrees
  • Black ice: wet roads that have frozen over
  • Icy roads: freezing rain
Danger level 3 (Considerable danger)
  • Impact:
    • Sudden, acute danger of skidding
    • Icy roads to the extent of being impassable
    • Disruption to air travel
    • Branches breaking and falling as a result of their ice load
  • Recommended action: keep an eye on local weather developments and stay informed; always follow the official advice.
  • Freezing rain: up to 2 mm
Danger level 4 (High danger)
  • Impact:
    • Sudden, acute danger of skidding;
    • Road and air travel brought to a standstill;
    • Disruption to rail travel;
    • Falling branches or trees as a result of their ice load;
    • Interruption of electricity supply and/or telephone network, particularly in regions that are not easily accessible.
