R (on the application of Herron and another) v Parking Adjudicator[2010] EWHC 1161 (Admin), [2010] All ER (D) 219 (May)
Under reg 4 of the Traffic Signs Regulations and General Directions 2002 (SI 2002/3113) every part of every road in a controlled parking zone, other than a parking bay, had to be marked with a single or double yellow line (with or without the “loading and unloading” equivalents), except where an alternative parking prohibition was marked out such as that imposed by zig-zags on the approach to a pedestrian crossing. Any non-compliance, however so arising, was immaterial if it was too far from the location of the particular motorist’s contravention to have led him into error.
