If the driver is you, you can tell us, as the owner of the vehicle has responsibility for payment, not the driver. Of course they may be one and the same.
A quick look at Arragon Road on GSV shows a lot of single yellow lines and the hours are 08.30 to 18.30, so this does look a bit of a money-grubbing PCN, I have to say. However, I cannot see any credible appeal argument re the contravention itself. The PCN also looks OK-ish, although I'm not happy with the text saying what to do if one receives a Notice to Owner.It is not strictly in accordance with the mandatory information, which emphasises that even if a challenge is made before a Notice to Owner is issued, that reps must be made afresh against the NtO. This is to avoid the situation of a PCN recipient submitting a challenge, but not getting a response, receives an NtO, but doesn't submit the reps again as he thinks he has already made representations.
I don't think the text on the PCN is clear enough on this aspect. Quite why the council couldn't have just put the text in the regulations on PCN content straight into its PCNs is a mystery.
