Oh dear, that hardy annual we see so often, Station Parade, Barking, appears again !
Unfortunately, GSV is not totally up-to-date in this area, but even so it will be of great help if you can give us your route that took you into and out of Station Parade, plus the PCN Number and your car registration. We can then go and look at the evidence on B & D's website.
The PCN is absolutely nothing to to with HGVs over 7.5 tonnes.There is a fairly well established 'No Vehicles' along part of Station Parade that you seem to have fallen foul of. The signs used are the usual "Flying Motorbike" signs. Here they are as you come up to Station Parade from Cambridge Street and turn right : -

Except, of course, that this view is November 2020, the latest GSV view so unless we can see photos taken recently it is difficult to give advice.
What is the source of the photos you have posted ?
