in shady areas, u most likely wont even see it until its too late. can be found especially on bridges. the road will look an off-grey. it's very subtle, and u'll miss it if u dont realize what it is. if u suddenly see cars skate almost sideways when they're about to go over a bridge, it's a dead giveaway that black ice is ahead. sometimes, u dont even get such a warning. at night, it can look like the road is wet, and in actuality, it's pure ice.

True "black ice" gets it's name from the roadway, which is visible thru it. Like others have said, it can be so thin that you can't see it at all. This will form on bridges and overpasses first when the air tempurature is at or below 32 degrees, since those surfaces don't have the benefit of the warmer ground under them. It will also form when the road surface is very cold, from fog or mist coming up from a river or body of water that settles as ice on the road, such as approaching or leaving a bridge. Anytime the humidity is high and the tempurature reaches the "dew point", the moisture in the air will condense on the roadway, and if the temp dips to 32 degrees, you can get "black ice". It will also form on concrete roads, but nobody calls it "gray ice".

"Black ice" is really clear ice. Because you can see the road beneath it, it looks black. It's a problem because drivers don't see it and are therefore unprepared for it. My first winter in the Midwest of the USA, I crashed twice on my bike on black ice.

It's an invisible sheet of ice on the road. You don't see it coming and then wrecks start to happen. It looks to be regular pavement but then you realize it's ice covered.

Thin layer of ice very slippery,very dangerous,very hard to see it on the road way.

Black ice forms when the ground or asphalt temperature is warmer than the air temp. The condensation formed by this temp. difference will freeze on the surface of the asphalt which will appear as "black ice" You cannot see it but it's there so watch your speed on the roadways Around dusk and dawn especially.

i dont know what a lot of these ppl are talking about
explanation: it rains, okay, then the temperature gets colder and freezes the water, which turns it into ice, then later it gets hotter and it melts (a little) Next it rains again and freezes. Thus, makeing it twice as "slippery". hope this helped
