I see only one lane in either direction, but because there is a central reservation I believe that the description “dual carriageway” is correct. Had a (amicable) squabble with a mate, who says it can’t be a DC unless two or more lanes on both sides. Thoughts?
A dual carriageway is named as such by virtue of having a physical divide between the oncoming vehicles. It matters not how many or how few lanes it has, the physical divider is the key.

Dual carriageways
A dual carriageway is a road which has a central reservation to separate the carriageways.
No mention of how many lanes and you can have 4 lane single carriageways.
There is another Single Lane dual carriageway in Norfolk in a place called Scottow, it is a couple of narrow country lanes with a bank and trees between them. It’s all been marked up properly as a dual carriageway.
does anyone know exactly where this happened, I would like to have a look at it on streetview; it would appear the overtake was left too late and the 4x4er got inadvertently funnelled into the wrong carriageway. Bad impatient driving would seem the obvious culprit but is the road layout / signage clear enough.

The signage is fine. It warns you in plenty of time that is still a single carriage road.

Terrington St Clement, according to the rag.
If I had been a bit more observant I would have seen the co-ordinates on the vid
Long sweeping left hand bend with hazard lines, the road then begins to straighten with the hazard lines replaced with short broken lines, after 250m the “Single file warning sign appears” then in a further 120m the dual section begins. I also don’t see on the approach any of those keep left arrows on the road.
I am not trying to excuse the driver, but that is a poorly marked begining to a dual section
Notorious accident blackspot, a fatality there this week, and a young couple killed on xmas day a few years ago.
The road is “dualled” there to provide a refuge in the center of the A17 for vehicles using the staggered crossroad.
Was told by a traffic plod that if you can roll a ball from the near side kerb to the opposite near side kerb unrestricted it’s a single cartiegways .if it hits a kerb or barrier first it’s a duel no matter how many lanes
As everyone else has said, dual - meaning two - refers to the number of carriageways. So any form of physical central reservation (kerb, grass or barrier) means there is more than one carriageway.
The number if lanes is irrelevant, as a dual carriageway can have one lane in each direction or it could have six.
And a single carriageway can be three four or, in the case of the Aston Expressway, seven lanes wide.
The road in question on the A17 is a fairly common design known as “single lane dualling” which is to provide a protected central refuge for right turning traffic.
