Free Traffic Legal Advice

Do, please, note that a sign with no days or times means it applies 24x7

Except when it doesn't e.g. the resident permit holder bays in the same CPZ follow the same hours but there are no days/times on their signs. (I mean, that might be a defect in how Edinburgh interprets the legislation, but they certainly don't enforce those bays 24/7)

Should there be any BB usage anyway if the disabled person was no longer a passenger?

The location of the photo appears to be here: https://maps.app.goo.gl/6BFyfqxfJL9P82fj9

and the prohibition is presumably the "no motor vehicles except for access" signed at the previous junction: https://maps.app.goo.gl/FcwGpMF3rS9X2UBY6

I take it you were roughly here?

The council has GIS mapping here which you can use to look up the extent of adopted highway - the "crossovers" are part of the adopted pavement. Unless you actually mean you were behind the pavement and on the construction site itself?

I did not notice any advance signage elsewhere.

Assuming it hasn't been taken down since July 2024, you would have passed the advance signage here: https://maps.app.goo.gl/V5jdUTy8i6yyNfc7A

There is a one-way sign visible in the video (different from the signage in 2024) - I'm not sure whether that alone is sufficient but it does suggest the restriction still applies.

But where is the private property boundary here?

Probably at the tree line. I think it reasonably obvious that you're on the road verge, not somebody else's grass.

Or to put it another way, if you think parking there is permitted, what additional steps do you think the highways authority would have to take to make parking on the verge illegal?

(I'll defer to others on whether there is something irregular about the PCN or otherwise which may save you, but I don't think "I wasn't on the road" is going to work here)

I feel there was no contravention, since the sign when entering the road states "Controlled Zone V Mon-Fri 9am-5pm". The alleged contravention was on 24/01/2026 at 14.18, which was a Saturday. Furthermore, I found this: https://www.lbhf.gov.uk/news/2026/01/trial-make-wormholt-safer-and-quieter
It says "A new neighbourhood improvement trial in the Wormholt area is being enforced with PCN fines from 5 January. It will continue to cut congestion and pollution. Out-of-borough motorists have received warning notices about the scheme since 5 November."
I assume I am one of the out of Borough motorists? ; but there is no signage to this effect.

You can read the (current) signage on the video - it's no motor vehicles at any time, except taxis and permit holders.
