I assure you, you get icy roads and snow at 28-30f. Upstate NY gets tons of snow and most of that is above 25f. I don’t see it get in the teens too much. Single digits or colder is pretty rare. All depends on the region up here. Due to the lakes, it is all over the place.
Yes. Even if you get bitched at. Decent people will just ask more questions until they get what they need from you. Better to give more information than none. Try your best.
Actually, sometimes going through every single step on how you ended up with the issue solves it… Done that a few times.
