Question about terminology: C-road network

What is "county-specific C-road network"? Is it some USA term? Mateusz Konieczny (talk) 08:29, 11 February 2022 (UTC)

It's UK terminology. From the UK Government definition: "classified unnumbered – smaller roads intended to connect together unclassified roads with A and B roads, and often linking a housing estate or a village to the rest of the network. Similar to ‘minor roads’ on an Ordnance Survey map and sometimes known unofficially as C roads". They'd mostly be highway=tertiary.

I've raised a query on Talk:Roads in the United Kingdom to ask about this – please do contribute if possible. I've included outputs from TagInfo as well. In practice, official_ref is rarely used on roads in the UK, and highway_authority_ref takes a massively larger share. In fact, the highway_authority_ref=* page even says that this is the tag used in GB. LateNightTone (talk) 13:50, 21 January 2026 (UTC)

Relationship to unsigned_ref

It would be helpful if the page could better explain the difference to unsigned_ref and highway_authority_ref (where one tends to be used over the other, etc.). Confusingly, the same example image is used in multiple articles. Osmuser63783 (talk) 06:36, 10 August 2024 (UTC)
