Thank you for your responses. I see now from your photo I should have seen that I could have turned right at that sign although I was already travelling in bus lane. I was by then disorientated and panicking for myself and my hubby looking for a quick left turn to exit bus lane. Any right turn in my memory would take me back to the seafront anyway so I felt trapped in bus lane focusing on finding a left turn to exit bus lane asap. It was my bad but I was totally disorientated by the changes. Last time I drove that way we would bear left past the Royal Pavillion and the road took us straight along to London Road, now it seems at the bend you must turn up by the theatres because road here changes into bus lane 😢. I was going by old memories and by time I realised it had become a bus lane I was already in it. It was a genuine error with no intent whatsoever but is my explanation feasible or should I just pay the fine? Thank you again x
