How to Appeal a Yellow Box Junction PCN

A yellow box junction Penalty Charge Notice (PCN) is a moving traffic contravention issued by a local council, not a private company. These are typically captured by CCTV cameras and sent to the registered keeper by post. Because the offence is recorded on video, councils issue large numbers of these notices, but that does not mean every one is correct or unappealable.

This guide explains the statutory appeals process under the Traffic Management Act 2004, the discount period, the grounds that often succeed, and what to do if you have already missed an early deadline. FineFlip provides educational information to help you navigate the process; this is not legal advice.

What is a Yellow Box Junction PCN?

Yellow box junctions are painted with a grid of yellow lines. It is a moving traffic contravention to enter the box unless your exit is clear, or, if you are turning right, unless you are prevented from moving only by oncoming traffic or by other vehicles waiting to turn right.

Councils with delegated enforcement powers — including all London boroughs and many other English and Welsh authorities — can issue PCNs for yellow box contraventions using CCTV footage. In London these are Band A contraventions, currently set at £160 in outer London and £160 in inner London (figures set by the Mayor and subject to change; check your PCN for the exact amount). Outside London, charges vary by authority.

Key Deadlines You Must Not Miss

Because a yellow box PCN is sent by post, the standard discount period is 21 days from the date of the notice (not the date you receive it). If you pay within that period you pay 50% of the full charge. This is the only statutory discount; there is no other reduced rate.

If you intend to challenge rather than pay, submit an informal challenge within the same 21-day window. Making a challenge in time normally pauses the discount, but check the wording on your specific notice. If the council rejects your informal challenge, they will issue a Notice to Owner, giving you 28 days to make formal representations. A further rejection produces a Notice of Rejection, after which you have 28 days to appeal to an independent adjudicator.

The Statutory Appeals Process Step by Step

Stage 1 — Informal challenge: Write to the council explaining why the PCN was wrongly issued. This is your first opportunity and costs nothing. The council must consider it.

Stage 2 — Formal representations to the council: If your informal challenge fails you receive a Notice to Owner. You have 28 days to make formal statutory representations. The council must respond in writing with either a Notice of Acceptance (cancelling the PCN) or a Notice of Rejection giving reasons.

Stage 3 — Independent adjudicator: If the council rejects your formal representations, you can appeal to an independent adjudicator within 28 days. In London this is London Tribunals; outside London it is the Traffic Penalty Tribunal. There is no fee for drivers. The adjudicator's decision is binding on the council. Missing this deadline removes your right of appeal.

Grounds That Often Succeed

Review the CCTV footage — you are entitled to request it — and look carefully for any of the following before drafting your challenge.

  • ▸Your exit was clear when you entered the box: if traffic stopped unexpectedly after you entered due to circumstances beyond your control (such as a pedestrian stepping out or a sudden signal change), this is a recognised defence.
  • ▸You were turning right and were held only by oncoming traffic or other right-turning vehicles: this is an explicit exemption; the footage should show this clearly.
  • ▸Signage or road markings were missing, obscured, or non-compliant with the Traffic Signs Regulations and General Directions 2016.
  • ▸The CCTV footage is unclear, of poor quality, or does not show your vehicle entering the box with the exit blocked.
  • ▸The PCN contains a material error — wrong vehicle registration, incorrect location, or wrong contravention code.
  • ▸The notice was not served within the statutory 28-day period from the date of the alleged contravention.
  • ▸Exemptions apply, for example emergency vehicles, or you were directed into the box by a police officer or traffic warden.

How to Request and Use the CCTV Evidence

You have the right to view the CCTV footage. Include a request for the footage in your informal challenge or formal representations. Councils must disclose it if you ask. Watch it frame by frame: look at the moment you entered the box and whether your exit road was clear at that precise instant, not a few seconds later.

If the council fails to provide footage within a reasonable time, this can itself be raised as a procedural failing in your representations or before the adjudicator.

What Happens If You Miss a Deadline

If you do not pay or challenge in time, the council can issue a Charge Certificate, which increases the outstanding amount by 50%. After that, they can register the debt at the Traffic Enforcement Centre and seek a warrant for enforcement agents (bailiffs) to collect.

If you did not receive the original PCN or Notice to Owner, for example because you had moved address or the documents went astray, you may be able to make a witness statement to the Traffic Enforcement Centre explaining why you did not respond in time. If accepted, the process is wound back to the appropriate earlier stage. Act promptly if you discover a debt at this stage, as further enforcement can follow quickly.

Tips for Writing a Strong Challenge

Be factual and specific. Refer to the contravention code, date, time, and location shown on the PCN. Describe exactly what happened and why it supports your ground of appeal. Attach any supporting evidence: a map, photographs of the junction markings or signage, a dashcam still, or a witness statement.

Keep your challenge concise. Adjudicators read many cases; a clear, evidence-backed argument is more persuasive than a lengthy narrative. Do not exaggerate or make claims you cannot support. If you have a genuine ground, state it plainly.

Frequently asked

Can I appeal a yellow box PCN if I was only briefly in the box?

The duration you spent in the box is less important than whether your exit was clear when you entered. If the footage shows the exit road was clear at the moment you crossed the line into the box, you have a strong ground regardless of how long you remained there.

Does making an informal challenge protect the 50% discount?

In most cases, submitting an informal challenge within the 21-day window means the discount is preserved if the council rejects your challenge, so you can still pay at the reduced rate at that point. However, the exact terms depend on the wording of your specific PCN, so read it carefully.

What is the difference between London Tribunals and the Traffic Penalty Tribunal?

Both are independent adjudication services that hear appeals against council PCNs, but they cover different areas. London Tribunals handles appeals from London boroughs. The Traffic Penalty Tribunal covers councils in England outside London, and also Wales. You appeal to whichever body covers the area where the contravention was recorded.

Will the council accept my appeal if I simply did not see the yellow box markings?

Not seeing the markings is generally not a successful ground on its own, because drivers are expected to know the Highway Code. However, if the markings were faded, damaged, or non-compliant with legal standards, that is a separate and potentially valid ground. Check the footage and, if possible, visit or photograph the junction.
