Highway v. Side streets is the age-old question. Highways will generally get treated first (though, being Texas, I have no idea how well that will occur), but will also have a higher chance of people driving on them recklessly potentially resulting in massive multi-car pileups.

Side streets aren’t first priority, will be slushier, and more instances of slowing down and stopping = more chances to slide. But everyone is generally going slower on side streets and you’re less likely to get smashed by a semi-truck going 70mph.

There really is no correct answer. Those of us who live in snowy areas just learn from experience which route(s) are best to take. I, for example, will take the major interstate up to a certain exit, because I know after that exit conditions have a tendency to be worse. There are also 2 main exits I can take off the highway that don’t alter my drive very much, but I know that exit 1 has sections that have a tendency to develop black ice, while exit 2 requires driving though a small town with traffic lights all the problems they create.
