Back in early 2000s, we were driving back to Virginia from Texas one Christmas and heavier snow had hit the east coast the night before and that day. All was good until we hit Charlotte, NC. I think the highway normally has 4 lanes going through, but it had 7 lanes that day because people couldn't see the road through the ice sheet. There was lots of speeding and after a semi almost killed us sideways, I made hubby take the next exit. Told him I'd find a way home. Luckily the atlas did show well enough to take back roads. Foot of snow is much easier to drive in than the ice sheet.
We got back on the freeway on the other side of the city. No traffic really because they were all stuck in a big accident now. We saw it on the news the next day and were glad we got off when we did.
