Is a freaking clue. Today there was a 52 car pile up in Virginia, the cause, less than an inch of snow. When temperatures are near freezing, when snow is falling, even if it appears that the roads may not be slick, ice can be there. The wife rolled the explorer a year ago when it was 40 degrees out and it had rained the previous night. Black ice has no mercy. If you are driving in the white stuff, just because the speed limit says 65, doesn’t mean you should be doing 65. I also learned this the hard way, though I wasn’t even trying to do the speed limit in my incident.
