Dear forum.

I recently received a PCN for 53c failure to comply with a restriction on vehicles entering a pedestrian zone.

This took place on Crawford Road SE5, which I entered via a left turn from Valmar road during the restricted school hours.

I quickly appealed said PCN with the following:

Reason: Inadequate or unlawful signage
I entered the pedestrian zone unintentionally as there was no indication or warning that I was approaching a
restricted zone.
As you can see in the footage I approached Crawford road from Valmar road.
On Valmar road approach to Crawford road there is no advance warning of the pedestrian zone.
There are no signs facing Valmar road to indicate a left turn should not be made onto Crawford road.

I have now had my appeal rejected with what I believe to be a nonsense response, here is an excerpt:

I have noted your comments footage you approached Crawford road from Valmar road. On Valmar road approach to
Crawford road there is no advance warning of the pedestrian zone. There are no signs facing Valmar road to indicate a left
turn should not be made onto Crawford road. I can advise that the restriction signs, which are displayed on both sides of the
carriageway, there are advance warning signs visible to motorists entering Crawford Road from Warner Road

It appears their response to my challenge of the fact there is no advance warnings of the restriction, or signs facing Valmar road, is that there are signs and advance warnings on a totally a different approach? It is as if my appeal was not actually read and just automatically rejected by a robot. 

Despite there being what I believe to be inadequate signage, I do not see how I can appeal this further.
