PCN code 50: performing a prohibited turn
What this contravention code means, and how to appeal it · Moving Traffic
Code 50 means the council or TfL recorded your vehicle as performing a prohibited turn. Unclear road signage, or a camera that appears to have recorded the wrong moment, are both grounds worth challenging.
Full description on the ticket: “Performing a prohibited turn.”
Letter after the code, like 50j?
A letter after the number narrows down the exact circumstances: j means camera (CCTV) enforcement, l means no left turn, r means no right turn, u means no U-turn. 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.
