PCN code 96: parked with engine running where prohibited
What this contravention code means, and how to appeal it · Off-Street
Code 96 means the council or TfL recorded your vehicle as parked with engine running where prohibited. If you paid but it wasn't recorded, or the car park's signage didn't make the terms clear, that's worth challenging.
Full description on the ticket: “Parked with engine running where prohibited.”
Can I appeal this?
Yes. This is a statutory Penalty Charge Notice from a council or TfL, not a private charge, so you have a formal right to challenge it before it escalates into a Charge Certificate.
