@LemmyC you can just copy & paste:
Dear Lancashire County Council,
This is a ridiculous PCN that should obviously be cancelled. My car cannot have been parked more than 50 cm from the edge of the carriageway because my vehicle was parked literally on top of the edge of the carriageway. I was technically parked on a vehicle crossover and this does not interrupt the pavement or extent the carriageway, but in this instance the council has even provided a handy road marking showing where the edge of the carriageway is, I have highlighted this in the attached picture.
In light of this it would be wholly unreasonable for the authority to reject this representation.
Yours faithfully,
Send this online and keep a screenshot of the confirmation page. Obviously upload the photo I've posted with your representation. If a line is "decommissioned" they should remove it properly, but in any case the edge of the carriageway continues to be where it is regardless of whether there are any lines or markings.
