Black Ice Detectors

I drive slow and let the "fast guy" be my black ice detector. Also - remember that bridges tend to freeze quicker than roads - learned that the hard way (40 yrs ago).

Constant downpour and 32*F does not make for black ice

Surface temp below 32*F and a light rain makes for black ice formation (thin layer of ice where road surface shows thru)
*Bridges, low areas are prime for 'black ice'

Be attentive...look for pathes of road that looks NEW or DARKER then surrounding road area


Tech Devices are available .......
Black Ice Devices...goggle

Time to pull off for me! Have a cup of coffee and let it warm up.

My Dad was on the road for Many years, and I always heed what he said about Ice. When in possible freezing conditions, watch for snow blowing across the road. That is one for the first warnings you will get for black ice. As long as the show hits and sticks, its not frozen. When it hits and slides across, there is likely a layer if ice forming. So far, it has always proven true.

Watch the leading edge of mirrors and mirror arms for ice.
Tail light reflections on ground will change from rain to ice.
When in doubt, slow down.

X 2.
Or, when I notice that I'm suddenly feeling like I'm on a revolving deja vu carnival ride, with the same landscapes appearing to fly past me, over, and over, and over, again in a circular way.

Also if you all of sudden don't hear road spray coming from your tires, and the road still looks wet... Ease off and slow down gently...

Wet pavement will be shiny, black ice more dull, and as mentioned appear to be “new” looking pavement.

Howdy, any one have a black ice detector? I just had a 12 hr. ride in constant downpour , with temp hovering around 32 the entire time...It was a very nerve wracking ride......

Seriously, there's no "black ice detector" that I have ever heard of, besides that very bad feeling you get when you realize you're on some, and out of control.
Since you're still here to post this up, we'll assume you slowed down and survived, because you knew there was a possiblity that there was black ice on your route. And that's a good thing. :C

Yes, slow down and let someone else test the road surface in front of you. But, for those that like tech stuff, here you go.
