Yellow box junction — exit was clear at moment of entry
The legal test: don't ENTER the box if exit is NOT clear. If exit was clear at moment of entry but a vehicle ahead unexpectedly stopped (cyclist crossed, lights changed, accident ahead), the contravention is not made out. Contravention is about the entry decision, not duration inside.
Legal basis
Highway Code rule 174; TSRGD 2016 Schedule 9 Part 3; Traffic Management Act 2004 Part 6; for London: London Local Authorities and Transport for London Act 2003 s.4
How to identify this in your case
Review council CCTV. Look for: was exit clear at moment of entry? Did unexpected event cause obstruction?
Sample appeal wording
Dear Sir/Madam, Re: PCN [NUMBER] — Yellow Box Junction — [LOCATION] — [DATE] I challenge this PCN. The contravention did not occur. The legal test (Highway Code rule 174 and the TRO) prohibits ENTRY when exit is not clear. It is not a 'no stopping in box' rule. At the moment of entry the exit was clearly visible and unobstructed. Within seconds, [a cyclist crossed / vehicle ahead braked unexpectedly / lights ahead turned red / pedestrian stepped out]. This was unforeseeable and outside my control. Council CCTV at [TIME MARK] will show: - T-3 sec: clear exit - T entry: clear exit - T+2: unforeseen event blocks exit Under TPT's published grounds and consistent adjudicator decisions, the contravention is not established. Please cancel. Yours faithfully, [NAME]
Replace [PARKING DATE], [NtK DATE] etc. with your own dates before sending.
