What triggers a yellow box junction PCN?

CCTV cameras monitor box junctions and capture vehicles that are stationary within the yellow cross-hatched area. If the camera detects your vehicle has stopped (not just passed through), a PCN may be issued. However, cameras cannot always distinguish between legitimate stops (turning right, emergency stops) and contraventions.

Key defences against a box junction PCN

The most powerful defence is the turning right exception. Highway Code rule 174 explicitly permits entering a box junction and stopping when turning right, provided you are only prevented from completing the turn by oncoming traffic. Additionally, if your exit was clear when you entered but became blocked by unexpected circumstances, or if the markings were faded and unclear, these are valid grounds for appeal.

The appeal timeline

  • Day 1-14: Pay at 50% discount OR submit informal challenge
  • Day 1-28: Make formal representations to the council
  • If rejected: Appeal to Traffic Penalty Tribunal (free)
  • After 28 days: Fine increases to full amount
  • After 56 days: Risk of enforcement action

Tips for a successful appeal

Request the camera footage from the council — you are entitled to see it. Check whether your right indicator is visible in the footage. Use Google Street View to capture images of the junction markings and signage. Note the exact time on the PCN and compare with restricted hours if applicable. A well-structured letter citing the specific legislation has a much higher success rate than an informal complaint.

Frequently asked questions

How much is a yellow box junction fine?

Typically £130 in London (reduced to £65 if paid within 14 days) or £70 outside London (reduced to £35 within 14 days). Amounts vary by council.

Can I use dashcam footage in my appeal?

Yes. Dashcam footage showing your exit was clear when you entered the box, or that you were turning right with your indicator on, is strong evidence for your appeal.

What is the success rate for box junction appeals?

Box junction appeals have a relatively high success rate, particularly when the turning right exception applies. The Traffic Penalty Tribunal frequently cancels PCNs where the driver was clearly waiting to turn right.
