I grew up in snow country and learned to drive there, many decades ago, and although I don't often have need of the things I learned about driving in the snow, now that we live here in "the south," I will confirm the wisdom of (a) no sudden moves, (b) stay home rather than tow.
Years ago we lived at one end of a 1/3 mile long bridge out in the middle of nowhere. The bridge was actually a pair of Interstate standard 2 lane bridges across a river, and at the bottom of hills on either side. One morning we were awakened by someone knocking on the front door. It had been below freezing for a day, then rained overnight. The roadway on the hills was clear, but the bridge was covered in ice, and the lady knocking had slid off the end of the bridge and into the ditch in front of our house. Over the next two hours, multiple folks crossed that bridge. Some of them made it without issue, some did not, winding up eventually adding to the pile of cars in our ditch. I watched one guy, whose crossing of the river was an example of what created the ditch-pile. He came down the hill at the 65 MPH speed limit, got onto the bridge before noticing the pile up, and promptly stomped on the brakes, locking up all four. His car proceeded to spin, bashing fenders into the guard rail, spinning and bashing, all four locked up tight, all the way down the bridge. By the time he landed on top of the pile, he'd destroyed all 4 fenders. While it seemed like he spent a week twirling across the bridge, it was probably around 20 seconds.
The folks who made across without incident did so by doing nothing save letting off the gas just a little and coasting in a straight line.
Oh, yeah, we took a couple pots of coffee down for folks standing around waiting on the fleet of wreckers needed to remove the pile.
