OK, I see the advance sign that you say was obscured by a large van. The sign itself is ridiculously small too. However, the killer photo is this: -

The signs are so place as to be totally side-on until the turn is started and even then may not be visible from a vehicle. Obviously they are visible from their CCTV camera !! If those signs had been place further back by the end of the raised area, they would be more visible and harder to claim not seeable.

If it were me, I'd be taking them all the way. You must emphasise the placement of the signs, as well as mentioning the advance sign was obscured. If you had been turning right, you'd have a harder task convincing an adjudicator: -

Contrast the two views, one a left turn approach and the other a right turn. Useful to show both to an adjudicator, I think.

UPDATE:

Slightly disappointed but not wholly surprised, Haringey Council has rejected my appeal. Here's their letter:

We have carefully considered what you say but we have decided not to cancel your Penalty Charge
Notice (PCN).

We sent you a PCN because our CCTV camera evidence shows your vehicle entering a pedestrian zone when it was not allowed to. At this location there are two signs on either side of the road, these signs comply with the relevant regulations.

The red circle indicates a prohibition and is also illustrated in the current edition of the Official Highway Code. These signs are reflective and clear for all motorists to observe and comply with.

I have considered what you have explained in your representations, however I am satisfied on the balance of probabilities that the signage relating to the restriction was substantially compliant with the relevant regulations, clear and adequate.

As you have shown in your evidence, there is a clear advance warning sign on Park Avenue, which informs motorists of the pedestrian zone. You say that this sign was obscured by another vehicle, however the sign is positioned at a height that would still make it visible for all motorists to observe and comply with.

This sign in conjunction with the statutory signs make this restriction substantially clear. The onus therefore rests with the motorist to ensure that they comply with all traffic signs.

I'm happy to take this case to the Environment and Traffic Adjudicators if members here think I have a good case.

Thanks!

If it were me, I think I'd risk the extra money and take them to London Tribunals. Essentially, it is a typical Fob-Off letter. HOw do they know the advance sign is visible despite high-sided vehicles ? No, it's complete tosh.

Cheers. I’ll proceed accordingly then.
