I parked on a single yellow line at 8-15 because the restriction time said no parking between 8-30 to 6-30, when i returned my car had been removed by the council. It turns out on this 110 metre line there is another sign which states no parking between 8-00 to 6-30. i explained this to the council and they seem to think to have 2 conflicting time signs on one line is ok . could this be true.....?
