This guide explains how to review a yellow box junction PCN, why video matters, and how to organise a timeline before submitting a representation. The aim is to help you slow the process down, identify the correct route, and prepare a response that matches the evidence.
Informational disclaimer: This guide is general information for document-preparation support. It is not legal advice and it does not guarantee any result. Always check your exact notice, issuer, stage, and deadline before acting.
1. What a box junction PCN usually alleges
A yellow box junction PCN usually alleges that a vehicle entered a marked box junction and then stopped in circumstances prohibited by the relevant traffic restriction. The exact wording and route depend on the issuer.
Check whether the notice is from a council or TfL and use the appeal route shown on the PCN.
2. Why video evidence matters
Box junction cases are movement cases. The most important evidence is often the video because it can show when the vehicle entered, what the traffic ahead was doing, and whether an exit route appeared available.
Do not judge the case from one still image. The seconds before entry and after stopping can matter.
3. Vehicle position, exit route, and timing
Record where the vehicle was when it entered the box, where it stopped, how long it stopped, whether traffic ahead moved, and whether the exit was clear at the point of entry.
Make timeline notes while watching the video so your representation can explain the sequence in plain English.
4. Why screenshots may not tell the full story
Screenshots are useful for illustrating key moments, but they may not show movement, timing, or whether another vehicle changed the situation. Use screenshots as supporting evidence, not as a substitute for reviewing the video.
If the video does not support a point, leave it out. Unsupported claims can make the representation harder to follow.
5. How to organise a timeline
Write a short timeline with time stamps from the video. Note approach, entry, traffic position, stopping point, movement ahead, and exit. Keep it factual and concise.
Our guide on evidence for PCN appeals can help you decide what to include.
6. Deadline and submission route
Use the council or TfL route shown on the notice. Check the deadline, upload limits, accepted file types, and whether the portal gives a submission receipt.

7. How Appeality helps
Appeality helps users organise box junction PCN evidence, time-stamped notes, screenshots, and representation wording. It provides document preparation support and does not guarantee any outcome.
A short, ordered timeline can be more persuasive than a long complaint about the junction.
8. Box junction PCN checklist
- Confirm the issuer, PCN number, date, time, and location.
- Watch the full video evidence where available.
- Record entry, stop, traffic movement, and exit details.
- Use screenshots only to support the timeline.
- Submit factual representations through the official route.
