We've seen this location quite a lot over the years.
First off there is the advance sign for the bus lane: -
Find local businesses, view maps and get driving directions in Google Maps.
then the bus lane start signs, preceded by the dashed broad line at an angle, plus arrows on the carriageway to direct you to the right: -
Find local businesses, view maps and get driving directions in Google Maps.
Then you have the broad white line indicating the bus lane.
Find local businesses, view maps and get driving directions in Google Maps.
The traffic lights show you can turn left from the traffic lane: -
Find local businesses, view maps and get driving directions in Google Maps.
So from the above you might infer that taking the matter to London Tribunals is a lost cause, but there have been quite a few wins here with different adjudicators, based on inadequate/misleading signage, so if you're prepared to risk the full £130 you could win this one. As far as I can see, the signage that the adjudicators consider is poor remains unchanged. CLearly Lambeth make more than enough money from people who just cough-up the discount, to not bother about the cases they lose at London Tribunals.
Anyway, here is the London Tribunals webpage for looking at their statutory register: -
Go to the ETA register with option 'search', and type in the location as it is on the PCN, plus a start date, somthing like 01 01 2022 plus type in 'appeal allowed'.
I have no intention to pay this PCN, and would be fairly confident of challenging and winning, however I do not want to give the council any inch in this fight, hence coming here for advice before i make my informal appeal, and later follow up with the inevitable formal challenge after the rejection letter.
A word of warning. Follow the process and you could succeed, but if you lose at London Tribunals, you have to pay or bailiffs will be knocking at your door eventually. It's a double-or-quits gamble basically, with the odds looking quite good.
