Thats true, that is an important technicality.
From what I understand of various states road laws and... basically dialects... 'freeway' and 'highway' technically mean slightly different things, by state, and sometimes literally by county or city.
So... yeah. I'm not from Nebraska, you might be right.
But the... intent, that you're ascribing, to the law... I mean thats a factor in how a judge would rule, but... the actual texts of the relevant laws are factors as well.
