Yellow Box Junction PCN Outside London: The 'Forced to Stop' Defence That Wins

The One Defence That Beats Most Box-Junction PCNs

A yellow box junction PCN is issued when a vehicle is photographed stopped within the painted yellow cross-hatching at a junction. Under regulation 10 of the Traffic Signs Regulations and General Directions 2016 (TSRGD) and regulation 29 of the Zebra, Pelican and Puffin Pedestrian Crossings Regulations, the rule is:

> *"You MUST NOT enter the box until your exit road or lane is clear."*

The crucial word is "enter". You may enter only if your exit is already clear. If you entered when the exit looked clear, but vehicles ahead then stopped (causing you to stop within the box), the breach has occurred as a matter of law — the offence is one of strict liability, not intent.

But there is a single, narrow, statutory exception that wins the majority of box-junction appeals at the Traffic Penalty Tribunal: you may stop in a box junction when forced to stop by oncoming traffic when turning right (and only when turning right). Outside that exception, the defence shifts to procedural and signage challenges.

Where Box-Junction Cameras Are Now Enforced

From 31 May 2022, local authorities outside London gained Part 6 of the Traffic Management Act 2004 powers to enforce moving traffic offences, including box-junction contraventions, with cameras. As of 2026, 36 box junctions outside London are camera-enforced, with new sites being added every quarter. The current enforcing authorities include:

• Manchester (Trafford, Bury)
• Birmingham
• Leeds
• Bristol
• Liverpool
• Nottingham
• Sheffield
• Newcastle
• Cardiff
• Edinburgh (via parallel Scottish provisions)
• Glasgow (parallel Scottish provisions)
• Plus 50+ London boroughs (long-standing under separate London regulations)

Cameras outside London must operate under a statutory warning-letter period of at least 6 months before formal PCNs can issue. Check whether the camera location was within the warning-letter period when your alleged contravention occurred — if so, the PCN is technically defective.

Step 1: Identify Which Defence Applies to Your Case

Defences fall into four buckets, in order of strength:

The right-turn exception is the clearest winner. If the dashcam shows you with right indicator on, waiting for oncoming traffic, the exception applies as a matter of law and the PCN should be cancelled.

Step 2: Gather Evidence

For the right-turn defence, the persuasive evidence chain is:

• Dashcam stills showing: (a) right indicator activated, (b) oncoming traffic flow blocking the turn, (c) you waiting (not driving) within the box, (d) the moment the oncoming gap appeared and you completed the turn
• Map of the junction with arrows showing your direction of travel and the oncoming flow
• Time-stamped photos / video so the council cannot dispute the sequence

For other defences:

• Faded markings: dated photos of the yellow lines (council should repaint every 3 years under TSRGD; faded markings undermine the contractual offer)
• Camera not certified: a request under the Freedom of Information Act 2000 to the council asking for the camera certification register and the date the warning-letter period ended

Step 3: Draft the Representations

The strongest representations open with the statutory exception and then build evidentiary support. Skeleton:

```

[Your name and current address]

[Date]

[Council name]

Parking Service / Moving Traffic Team

[Address]

Reference: [PCN reference]

Vehicle registration: [VRM]

Formal representations against PCN [reference] issued on [date].

1. I am the registered keeper of [VRM]. I do not dispute that I was

the driver on the date in question.

1. I was turning right at [junction name] when I was forced to stop

within the yellow box junction by oncoming traffic. The statutory

exception in regulation 10(3) of the Traffic Signs Regulations and

General Directions 2016 applies.

1. The exhibits attached are:

- Dashcam still A: indicator activated, approaching the junction

- Dashcam still B: oncoming traffic blocking the turn

- Dashcam still C: stationary within the box, indicator still on

- Dashcam still D: oncoming gap, completing the turn

1. I respectfully request that the PCN be cancelled.

Yours faithfully,

[Signature]

Step 4: If the Council Rejects

You can escalate to the Traffic Penalty Tribunal within 28 days of the rejection. The TPT is free, online, and decides on the papers in most cases. Decisions are usually issued within 28 days of submission.

The TPT does NOT take a "benefit of the doubt" view — they require documented evidence. The right-turn exception cases almost always come down to whether your dashcam evidence is clear and your narrative is consistent. Without dashcam, the exception is hard to prove.

If your evidence is weak, do not escalate to TPT — pay the discounted amount within 14 days of the rejection and accept the loss. The CHARGE almost always stays at the £20-£70 contravention level (most councils enforce moving-traffic offences at the lower tier) so the cost ladder is much shallower than a parking PCN.

Step 5: The Two Common Council Counter-Arguments

When you cite the right-turn exception, councils typically respond with one of:

1. "The vehicle was not turning right" — they argue your photographs show ambiguous indicator status. Counter: dashcam timestamps + the angle of your wheels at the moment of entry.

1. "The vehicle entered the box when the exit was already obstructed" — they argue the exception only applies if you entered with a clear exit and were then trapped. Counter: the statutory wording is "forced to stop... by oncoming vehicles when turning right" — it does not require the exit to have been clear on entry. The exception is broader than the council often acknowledges.

The TPT's published case summaries support the broader reading. If your dashcam shows you turning right and waiting for a gap in oncoming traffic, the exception applies.

Numbers That Matter

• Yellow box junction PCN amount (outside London, lower tier): typically £70 / £35 paid within 21 days
• Yellow box junction PCN amount (London / higher tier): typically £130 / £65
• Warning-letter period for new camera sites: minimum 6 months under Part 6 TMA
• Tribunal escalation window: 28 days from council rejection
• TPT decision time: typically 14-28 days
