Challenge guidance for this situation
This page explains a common yellow box PCN appeal angle. If the checker brought you here, the guidance below is adjusted using your yes/no answer in the URL. This is not legal advice.
Your draft letter
Replace everything in [square brackets] with your own details. Scroll inside the box if the text is long.
Subject: Representation / appeal: yellow box [PCN number] I dispute this penalty. Only a very small part of my vehicle was over the marking, [e.g. back wheels on the edge / front just over; describe]. It was for a very short time. This should be treated as legally insignificant. The infringement is not proportionate to a full stop in the box due to stationary traffic. [Date, time, location, registration.] Yours faithfully, [Name]
Guidance for your case
What to do next
Describe how little of the vehicle was inside and how briefly, match what the video shows.
Why this can matter
Very small overlap with the box for a short time has been treated as too minor to enforce.
Tiny overlap: say which wheels or bumper, and for how long.

What to do next
If most of the car was in the box or it was there for a clear time, try other topics instead.
There is no ready-made letter for this combination. Use other topics in the wizard, or challenge the PCN with your own wording and the council's evidence.
