PCN code 52: failing to comply with a prohibition on certain types of vehicle
What this contravention code means, and how to appeal it · Moving Traffic
Code 52 means the council or TfL recorded your vehicle as failing to comply with a prohibition on certain types of vehicle. Unclear road signage, or a camera that appears to have recorded the wrong moment, are both grounds worth challenging.
Full description on the ticket: “Failing to comply with a prohibition on certain types of vehicle.”
Letter after the code, like 52j?
A letter after the number narrows down the exact circumstances: j means camera (CCTV) enforcement, g means goods vehicles exceeding max gross weight indicated, m means motor vehicles, s means solo motorcycles, v means all vehicles except non-mechanically propelled ones being pushed, x means motor vehicles except solo motorcycles. We factor the exact suffix into your letter automatically.
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.
