Freezing rain is one of winter's most destructive hazards.
Unlike regular snow, freezing rain lands as cold liquid and freezes instantly on contact, forming a heavy glazing of ice on power lines, tree branches, and roads.
The Hazard of Downed Power Lines
The accumulation of ice can weigh down high-voltage wires, causing widespread blackouts that last for days. Never approach downed wires—stay at least 10 meters away and report them immediately.
Safe Winter Road Travel
Black ice is nearly invisible on asphalt. Avoid driving during active freezing rain warnings. If you must drive, slow down significantly, double your following distance, and ensure your vehicle has high-quality winter tires.
