No, you don't need to declare any fines.

The reason that road doesn't have a no entry sign is that you are allowed to go down it turning left. It's no right turn into it, probably because it was getting abused as a short cut / rat run.

Your second clue, if you missed the sign, was the 'build out' (sticky out curvey bit) that was meant to make you realise that you're not supposed to drive down there.

You get a lot of these daft things in London (and Bristol, and presumably other places). Where I used to live (Stamford Hill) there were certain roads that you were not allowed to enter from one direction at night time. All to do with ladies of the night apparently.

Thanks,yes hard to see the curvey bit as well. Also not an area I have driven before so again I need to perhaps slow down a little in areas that are unfamiliar I guess.

Just annoyed still!

John. I have every sympathy. That’s a very broad street and one sign on the opposite kerb could easily be missed or obscured if traffic was busy. Also if you move back through your first picture the sign would be obscured from some angles by the ruddy great plane tree.

As the built out pavement equally narrows the access for traffic from both directions I wouldn’t have seen that as an indication not to turn right. But perhaps it is.

Assuming the meagre sign meets the regulations I think that, as you say, you are going to have to pay.

This should be telling you something about your driving, you need to adjust your driving to pay more attention to traffic signs. I certainly think they need to have painted the road slightly differently. In a busy city such as London, there can be many thing going on.

Yellow box junctions are another money maker. Traffic signal timing changes are another, where light turn green and then quickly turn red.

You need to pay close attention to the 20mph zones.

Google Maps can sometimes be out of date, and in a few cases, it can take a couple of years to update.

Oh I'm very cautious! If anything too much sometimes that more often than not I'm under the speed limit and always take note of where cameras are so am very careful but these signs are just popping up when you least expect them and there's more of them in London than say a few years ago. Like I said in the example, that sign only came up in the last two years I reckon because it wasn't there in 2019 (According to google). Also very annoying that Google didn't update this themselves and led me down there!

As are bus only lanes with cameras, which mostly are empty 99% of the time.
