Use highway=trunk for high performance or high importance roads that don't meet the requirement for motorway. In different countries, either performance or importance is used as the defining criterion for trunk...

I don't think I have the experience to give an opinion, but here is what the wiki says about US trunks:

Trunk is the proper classification for major through routes that lack full access control, regardless of their number of lanes, speed limit, median (or lack thereof) etc. Most controlled-access highways without adequate speed or travel lanes or with obstructions should be designated highway=trunk.

Typically, trunk in the US has been meant an expressway, ie, basically a freeway, but it might have intersections. Or it might be fully controlled, but only a single carriageway. Or it's dual carriageway, but only one lane on a carriageway.

In some situations (Not for this street specifically) while on site I have seen private roads that are used by multiple households. For example sometimes a small clump of households are extended family. Would that count as a driveway or residential road?

Feel free to comment or roll back these changesets if my landuse edits are excessive or incorrect.

I'll make sure to include direction when adding stop/yield signs in the future! Thanks for doing that.

Thanks for the explanation! I appreciate it.

A while ago I went back and forth on what tags the paths on campus should have, I eventually settled on following this bike map: https://www.usu.edu/abb/images/Printable-Bike-Map-Trifold_Page_2.jpg
- "shared sidewalks" on that map as cycle + foot designated
- not marked on that map as generic "path".

What do you think of this? Or should they all be the cycle + foot designated? Not sure.

Got it, thanks for the explanation!
