I was soon to be turning left and might have went into the Bus lane earlier than I should have. I have entered when it was on zigzag markings and I thought that was the end of the bus lane as I could see the signs in the distance where it was right turn only in the lane I was in.  The sign in front of the crossing was hidden from my view by a tree obstruction and it was too many things too look at as I had to focus on the pedestrian crossing and lights potentially turning red.

What would be a good reason to dispute this? Thanks for your help

Dear Ealing

I make this challenge against PCN..................

1. Insert your own narrative.

2. The repeater sign to diagram 959B is obscured by foliage.

3. I put you to strict proof that the camera used to capture the video evidence is approved.  Unless you can do so, the evidence is inadmissible.

In light of the above, pleas cancel the said PCN.
