Boris Johnson's Narrow Escape

A while ago when I was with my mother in her car, she drove over an ASL not realising it until I told her that's she on an Advanced Standing Line, it was genuinely a simple mistake because she wasn't looking for it, she was looking at the traffic, the light, the junction etc.

now she doesn't drive over ASL once she realise her mistake.

so yes, it can be a simple accident.

So it's her fault for not concentrating enough - she should have been looking for it. What if there was a cyclist there?
