Seen the same thing on multiple sled trips. When you're cruising the highway and suddenly your trailer full of snowmobiles is next to your side window expect a heavy puckered moment.I've encountered black ice several times driving a tractor-trailer, once in bright sunshine in Montana. With the big truck your first clue is the tac needle jumps up as your drives lose traction, then your trailer tries to pass you in the other lane as it is now pushing the tractor which has lost contact with the pavement. If you stay off the brakes and have a deft hand you can reel it back in, sometimes it then tries to pass on the other side, etc.etc. One you get it straightened out your nerves are shot waiting for it to happen again, especially at night at the end of a long day.
Jeeps have 4 wheel drive and 4 wheel disc brakes. However, if the traction on ice is "zero", then 4 x 0 = 0. (There, I did the math for you).I'm not 100% certain this is from our North Texas freeze we are dealing with, but it's still enough for a chuckle.

Yeah... 4WD doesn't help you stop... it's all about the tires.Jeeps have 4 wheel drive. However, if the traction on ice is "zero", then 4 x 0 = 0. (There, I did the math for you).![]()
