On entering the box the exit was clear in the next lane.

If using this in your reps delete 'the exit was clear in the next lane' and replace with 'there was a clear exit ahead of the box'. The counter-argument, of course, is that you didn't choose to take it. How much space did you leave between you and the van ahead?

You could add that any infraction by overhanging the YBJ was de minimis and that you chose to stop when you believed you hac cleared the box.

Include it, but I think you'll struggle with the Dennis Road argument: there may not be a Denis Road but there is a Dennis Roundabout - see

Arguably, if there were a Dennis Road in Guildford, there could be room for confusion. But the nearest seems to be in East Molesey/Elmbridge.

Post up your draft reps here for comment before submitting. AFAIK Surrey will re-offer the discount if reps received by them in the discount period. At least your not in London with its £80/£160 penalties.

I got some help drafting reps from my daughter who is a law student and not a specialist in traffic law.

Grounds for challenging PCN:
A) The alleged contravention did not occur
    Driver's judgement and unforeseen circumstances: Upon entering the yellow box junction, it was judged there was sufficient space to clear the box without stopping. The driver believed the wheels were out of the box and deemed it a safe place to stop.
    De Minimis Encroachment: the vehicle's rear wheels were only minimally encroaching into the yellow box junction for a brief period. The driver believed the wheels had cleared the box, but this minor intrusion, particularly given the intention to comply with the rules and the momentary nature of the stop, should be considered de minimis and not a contravention for the purposes of enforcement.  Careful review of the CCTV footage of the incident is requested, specifically noting the extent of the vehicle's presence within the yellow box.
    The other vehicle was the primary cause of the alleged contravention: the regulations specify that you must not enter a box junction if your exit is blocked by stationary traffic. If another vehicle was within the yellow box, hindering the free flow of traffic, the system might have erroneously tagged my vehicle as being the one in contravention, or at least failed to consider full context.
    Entry point: the contravention occurs at the moment you enter the box. There was a clear exit ahead of the box. The driver decided the left hand lane had sufficient space so chose to stay in that lane and believed they had cleared the box.
F) There has been a procedural impropriety by the enforcement authority
Dennis Road does not exist in Guildford.  Searching online for Dennis Road takes you to Molesey

Thanks for looking.

Representations were rejected. 

The letter says the outstanding penalty charge is £35 until 21 days after the notice of rejection date (14/10/2025)

But when I try to pay online the only option is £70!  So I can't pay the proper amount
