Although, going about your business can be a little extra challenging when temps drop this low.
For example, Monday one of my employees clocked out to leave and found a completely flat tire on his car. After 20 minutes of attempting to inflate it, it was determined that there was no hope it would hold air. Tuesday he tried to remove the tire so he could take it in to have it replaced, but the tire was both rusted and frozen in place. After several heavy doses of penetrating oils and physical poundings, it finally came off. After the wheel was replaced, he tried to fire up the car, but the battery was dead/drained. When he finally got it jumped, he found the e-brake was frozen. When he unfroze the e-brake, the driver side door latch was frozen, so his door wouldn't stay shut. His dash lights also wouldn't illuminate. So after all that, he had to drive home on solid ice country roads while attempting to hold his door shut and using his phone light to see his dash.
Another example: Yesterday the garbage truck that was supposed to pick up all the garbage in my neck of the woods slid into a deep ditch/culvert at the side of the road near my house. The country road I live on is extremely icy because it's so cold that salts aren't penetrating the ice and the wind continues to throw snow onto the roads from the farm fields and builds ice thickness. My wife, on her way home, had to backtrack those icy roads and drive an extra five miles to get around the road barricade of emergency & utility vehicles trying to pull the garbage truck out of the ditch.
