Black ice is a thin, nearly transparent layer of ice that forms on roads, sidewalks, or other surfaces, making it extremely dangerous because it’s almost invisible. Here’s why it’s so hazardous:

Key Facts About Black Ice:

How It Forms:

Occurs when light rain, drizzle, or melted snow refreezes on cold surfaces (often at night or early morning).

Common on bridges, overpasses, and shaded areas (these spots freeze first).

Why It’s Dangerous:

Invisibility: Blends with pavement, looking like a wet patch.

No Traction: Creates a slippery surface for cars, bikes, and pedestrians.

Sudden Impact: Causes skidding, crashes, or falls without warning.

Where It’s Found:

Temperatures near freezing (just below 0°C/32°F).

After thaw-refreeze cycles (common in winter/early spring).

Consequences:

Driving: Loss of control, collisions.

Walking: Severe slips and injuries (e.g., broken bones).

Safety Tip: Assume wet-looking pavement is ice if temps are near freezing! 🚗⚠️

Fun Fact: It’s called "black" ice because it reveals the dark road beneath it. 🌑❄️
