The US system presents a complex problem for this, since most highway classification is delegated to the states, and they all have their own local schemes. In many counties in the US, rural roads are unnamed and have only reference numbers. A farm road may be "County Road 2200N" (which is a different classification from, say, "County Highway 23", and typically shown only on small blade signs, not banner signs) or "State Farm and Market Road #2134". As I understand it, it would fit pretty closely with what "unclassified" roads - which are a formal classification in the UK! - are understood to be. Near where I live, numbered 'US', 'State' and many 'County' roads do NOT reflect the governing body - they are all managed by the state department of transportation. Historically, they had other structures, but responsibilities were reallocated. The 'US' highway numbers are coordinated with neighbouring states, but the administration is by the state. There are also numbered but (nearly) unsigned 'reference routes' also maintained by the state to 'State' highway standards. I say 'nearly' unsigned because they do often have inconspicuous chaining markers with their numbers. Rather than labeling the governing body, the 'US', 'State' and 'County' designations around here reflect the grade of importance, expected level of traffic and expected quality of maintenance. Given that the designation reflects relative importance rather than administrative jurisdiction, despite the labeling, I'm comfortable with having US, State, and County numbered roads be 'primary', 'secondary' and 'tertiary' - but in the places where the counties number virtually every road, there is a need for a tier below 'tertiary' - and 'unclassified' seems to be it; it's a working category that might otherwise be 'quaternary.'
