Yellow Box Junction Fine Appeal UK

Updated April 2026 · 6 min read

A yellow box junction fine is a Penalty Charge Notice (PCN) issued by your local council for stopping in a yellow box junction. The enforcement is camera-based — cameras capture your vehicle entering and remaining in the box when exit was not clear. These charges can frequently be challenged successfully, because the legal test is specific and the camera footage often reveals a more nuanced picture than the still photographs in the notice.

Understanding the legal test

The Highway Code rule 174 and the underlying Traffic Regulation Order state that you must not enter a yellow box junction unless your exit road or lane is clear. The key word is "enter" — the question is whether the box was clear at the moment you drove into it, not whether it was clear when you were still in it.

There is a specific exception: you may enter and wait in a box when you are turning right, and are only prevented from doing so by oncoming traffic or vehicles waiting to turn right. In that situation, waiting in the box is lawful.

This distinction matters enormously. Many PCNs are issued where a driver entered the box when it appeared clear, then was blocked by traffic that moved into the exit after they entered. That situation is not a contravention — the contravention requires that the exit was not clear when you entered.

The most important step: request the camera footage

Always request the camera footage in your challenge letter. This is your most powerful tool. The PCN notice will typically include only two or three still images — one showing your vehicle entering the box, one showing it stationary in the box. What these images rarely show is whether your exit was actually clear at the moment you entered.

The video footage shows the entire sequence: the state of the exit before and as you entered, other vehicles' movements, and the full context of what happened. In a significant proportion of cases, the footage shows that entry was lawful — the driver entered when clear and was blocked by subsequently moving traffic.

State in your challenge letter: "I request a copy of all camera footage of the alleged contravention, including footage of the state of the exit road at the moment my vehicle entered the box, pursuant to my rights under the UK GDPR."

Grounds most likely to succeed

Box was clear when you entered

If you entered the box when your exit was clear and were subsequently blocked by other traffic moving into your path, there was no contravention. Request the footage — it will show the state of the exit at the moment of entry. State in your challenge: "The yellow box was clear when I entered. I was unable to exit due to vehicles which moved into the exit road after I entered the box. This does not constitute a contravention under The Highway Code rule 174."

Turning right exception

If you were waiting to turn right and were blocked by oncoming traffic, the Highway Code expressly permits waiting in the box in that situation. State this clearly and confirm you were waiting to turn right — the footage will confirm your intended direction.

Wrong vehicle

If the registration on the PCN does not match your vehicle, provide your V5C and state the discrepancy. Camera misreads are possible.

Traffic signals directing entry

If traffic signals at the junction gave you a green light to proceed and entering the box was necessary to comply with the signal, this context is relevant to the overall picture. The footage may show whether signals were a contributing factor.

Emergency circumstances

Genuine emergency circumstances — an ambulance behind you requiring you to clear a path by entering the box — can be raised as mitigation. CCTV footage of the area may support this if available.

The appeal process

Stage 1: Informal challenge (28 days from notice)

Write to the council within 28 days. Request the camera footage and state your grounds. If the council accepts, the PCN is cancelled. If rejected, you receive a Notice to Owner.

Stage 2: Formal representations (28 days from Notice to Owner)

Once the Notice to Owner is received, you have 28 days for formal representations. At this stage you can reference the footage if it has been provided, and make a detailed legal argument.

Stage 3: Traffic Penalty Tribunal (free)

If the formal representations are rejected, appeal to the Traffic Penalty Tribunal. This is completely independent of the council, free to use, and can be conducted in writing online. The adjudicator reviews the footage and both parties' submissions. Yellow box contravention cases are not uncommon at TPT and do result in cancellation where the entry was lawful.

How to write your challenge letter

Include the PCN reference, your vehicle registration, the date and location. Set out your grounds in plain English — describe exactly what happened as you entered the box and why you believe entry was lawful. Request the footage. Keep the tone factual and composed. Councils process large volumes of challenges — specificity and clarity are more persuasive than length.
