I have just been caught parking on a single yellow line outside my house. It seems the council have recently introduced a parking zone which has changed the operational hours of the yellow line. I don't know how recently, however, It can't be more than a couple of weeks. I believe they have complied with with correct signage. I have always parked on a single yellow on a saturday (which used to be allowable) when there has been no available spaces in the parking bays.
My question - is there any ground for appeal based on lack of warning of changes to hours of operation. I did not notice the new 'Parking Zone' signs at the end of my road. Given I have parked on the road daily for the last 8 months it did not occur to me to check whether the hours of operation had changed.
