Yellow Box Junction Fine: How to Appeal

Yellow Box Junction Fine: How to Appeal

Yellow box junction fines are one of the most disputed types of traffic enforcement in the UK. Many drivers receive these fines feeling they had no choice but to stop in the box. Here is the law, the exceptions, and how to appeal.

What Is a Yellow Box Junction?

A yellow box junction is an area of criss-cross yellow lines painted on the road at a junction. The purpose is to keep the junction clear by preventing vehicles from entering unless their exit is clear. They are found at busy junctions, particularly near traffic lights.

The Rule

Rule 174 of the Highway Code states: "You MUST NOT enter the box until your exit road or lane is clear." The word MUST means this is backed by law, not just guidance.

The specific offence is entering and stopping in a box junction when your exit was not clear. The contravention code is typically PCN code 99 (London) or varies outside London.

The Key Exception: Turning Right

There is one important exception: you may enter a yellow box junction when you want to turn right and are only prevented from doing so by oncoming traffic or other vehicles waiting to turn right.

This means if you entered the box intending to turn right and were stopped by oncoming traffic, you have NOT committed a contravention. This is by far the most common successful appeal ground for box junction fines.

How Box Junction Fines Are Issued

In London: Transport for London (TfL) and London boroughs enforce box junctions using CCTV cameras. Fines are issued by post with photos or video evidence. The fine is typically £160 (reduced to £80 if paid within 14 days).

Outside London: Box junction enforcement by camera is less common outside London. Most authorities outside London enforce box junctions through police or traffic wardens. However, some cities (Manchester, Birmingham, Cardiff, and others) are gaining or have gained powers to use camera enforcement.

Reviewing the CCTV Evidence

When you receive a box junction fine, you can (and should) request the CCTV footage. In London, TfL and boroughs usually provide an online link to view the video. For other authorities, request the footage in writing.

When reviewing the footage, look for:

1. Was your exit clear when you entered the box? If traffic moved into your exit lane after you entered, you may have a defence.
2. Were you turning right? If yes and you were stopped by oncoming traffic, the exception applies.
3. Was the box junction correctly marked? The markings must be clear and complete.
4. Were traffic lights involved? If the lights changed while you were in the junction, this affects whether you had a reasonable expectation your exit would be clear.
5. Was there an obstruction you could not foresee? For example, a vehicle ahead of you stopping unexpectedly.

How to Appeal

Step 1: Informal challenge (within 14 days)

Write to the issuing authority stating your grounds. Common grounds include:

• You were turning right and prevented by oncoming traffic
• Your exit was clear when you entered but became blocked by unforeseen events
• The box junction markings were unclear or incomplete
• The traffic signals contributed to the situation

Step 2: Formal representations (within 28 days of Notice to Owner)

If your informal challenge is rejected, make formal representations with the same or additional grounds and evidence.

Step 3: Tribunal appeal

If rejected again, appeal to the London Tribunals or Traffic Penalty Tribunal. Adjudicators at these tribunals regularly overturn box junction fines, particularly for the "turning right" exception.

Common Mistakes When Appealing

• "The traffic was bad": General traffic congestion is not a defence. You must not enter the box unless your exit is clear, regardless of how busy the road is.
• "Everyone else was doing it": Other drivers' behaviour is not relevant to your contravention.
• "I was only in the box for a few seconds": The duration does not matter. Any stopping in the box when your exit was not clear is a contravention.
• "I did not see the markings": Not seeing the markings is unlikely to succeed unless they were genuinely unclear or missing.

Successful Appeal Grounds

These grounds regularly succeed at tribunal:

1. Turning right exception: You entered to turn right and were stopped by oncoming traffic. This is the strongest defence.
2. Exit was clear but became blocked: Your exit was clear when you entered, but another vehicle stopped unexpectedly (e.g., to let a pedestrian cross). You could not have anticipated this.
3. Emergency vehicle: You stopped to allow an emergency vehicle to pass.
4. Markings unclear: The yellow box markings were faded, incomplete, or not visible (e.g., covered by road works).
5. Camera or evidence issues: The CCTV footage does not clearly show a contravention, or the camera angle makes it impossible to determine whether your exit was clear.

London vs Outside London

London has extensive box junction camera enforcement. Outside London, camera enforcement is less common but growing. Some key differences:

• London penalties are set by TfL or borough councils
• Outside London, the Traffic Management Act 2004 governs enforcement
• Some areas outside London have recently gained civil enforcement powers for box junctions, so this area is evolving

Key Tip

Always request and carefully review the CCTV evidence before deciding whether to appeal. The video may show that you did commit the contravention, in which case paying early with the discount is the cheapest option. But it may also show a clear "turning right" defence or an exit that became blocked through no fault of yours.
