1. Introduction: Why Box Junction Fines Are So Frustrating

Box junctions—often called “yellow box junctions”—are designed to keep traffic moving at busy intersections. Yet, for many drivers, they’re a source of stress and unexpected fines. You may have entered the box with every intention of clearing it, only to be caught out by sudden traffic, poor visibility, or confusing road layouts. The good news? Not every fine is justified, and there are clear ways to challenge a penalty charge notice (PCN) if you believe it’s unfair.

2. The Law Behind Box Junctions (Yellow Boxes)

Under the Traffic Signs Regulations and General Directions (TSRGD), you must not enter a box junction unless your exit is clear. The only exception is if you’re turning right and are prevented from doing so by oncoming traffic or vehicles waiting to turn right. Most fines are issued by camera, with councils providing video or photographic evidence. But enforcement must be fair, and the box itself must meet legal standards for size, marking, and signage.

3. Strong Grounds for Contesting a Box Junction (Yellow Box) Fine

• Poor Visibility or Faded Markings:
  If the box junction markings are worn, obscured, or not maintained to legal standards, you can argue the box wasn’t enforceable. Take clear photos to support your case.
  
  

• Inadequate or Missing Signage:
  Advance warning signs should be present. If they’re missing or unclear, this weakens the council’s case.
  
  

• Blocked Exit Was Unpredictable:
  If your exit was clear when you entered but became blocked by a sudden event—such as a breakdown, emergency vehicle, or pedestrian—you may have a valid defence.
  
  

• Turning Right Exception:
  Stopping in the box junction while waiting to turn right is allowed if you’re held up by oncoming traffic.
  
  

• Camera or Evidence Issues:
  If the video doesn’t clearly show your vehicle stopped in the box, or the time stamps are missing, you can challenge the PCN.
  
  

• Junction Design Flaws:
  Some box junctions are oversized, oddly shaped, or placed in a way that makes compliance difficult. If the box extends beyond the area needed to keep traffic flowing, highlight this in your appeal.
  
  

• Mitigating Circumstances:
  Medical emergencies, breakdowns, or unavoidable events should be explained and evidenced.
  
  

4. Step-by-Step: How to Build a Strong Appeal

• Request and Review the Evidence:
  Ask the council for all video and photographic evidence. Watch carefully for the moment you entered and left the box junction.
  
  

• Inspect the Junction Yourself:
  Visit the site, take photos of the box, signage, and any obstructions. Look for faded lines, missing signs, or anything that could have contributed to the alleged contravention.
  
  

• Draft a Clear Representation:
  Write a concise appeal, referencing the law and technical issues. Attach your evidence—photos, diagrams, witness statements.
  
  

• Submit Within the Deadline:
  You have 28 days to contest the PCN. If you pay within 14 days, you may get a discount, but appealing pauses the penalty until a decision is made.
  
  

• Prepare for Further Steps:
  If rejected, you can appeal to an independent adjudicator. Keep all correspondence and evidence organised.
  
  

5. Technical Details: Junction Types and Visibility Issues

• Complex Junctions:
  Multi-lane or unusually shaped box junctions can confuse drivers. If the box is larger than necessary or not positioned correctly, this can be challenged.
  
  

• Obstructed Views:
  If your view of the exit was blocked by large vehicles, street furniture, or poor lighting, mention this in your appeal.
  
  

• Temporary Roadworks:
  If roadworks or temporary changes affected the box junction or signage, include photos and details in your representation.
  
  

6. Conclusion: Don’t Let an Unfair Box Junction Fine Go Unchallenged

Many box junction fines are issued automatically, but not all are justified. By understanding the law, gathering evidence, and making a clear, well-supported appeal, you can fight your fine and stand a real chance of success.
