I expect it's all my fault and I'll pay up.
However, I knew when I was in the bus lane because it was written on the road, but by then it was too late. The photo shows me driving into the bus lane but doesn't show any signs to indicate it was starting (only the writing on the road) and I remember saying when I realised what I'd done, that I didn't think there been any signage.
Probably it's me, I missed it and should pay, but I'd like to appeal and ask them to show me what I missed. I was away on holiday, so can't pop back to check myself. At the least, I think it was probably one of those situations where it's not that clear if you don't know the road layout - there was one in our town where all fines were cancelled for the first 6 months because the signage wasn't clear enough.
Anyway, they've included details of the appeals process, but the fine is £70, £35 if paid within 28 days, but £105 if I use the appeals process unsuccessfully.
How can it be Ok to practically force people not to even try and appeal?
