Re: Question for spotters
"Except for Access" is supposed to mean : No vehicles allowed, unless those vehicles have a legitimate reason to travel over the road, eg. some narrow roads in town centres are barred to traffic unless, say, you live there, or in the case of an airport, to drop off/pick up at a terminal or go to the car parks etc. on airport, yet landside, property. Yet who defines what a legitimate reason is ? Can a spotter drive his car along the perimeter road up to an airport car park, even if he has no intention to travel to a terminal or to fly on an aeroplane, and then become a pedestrian ?
It sounds like the legislation was drafted to be deliberately vague. Typical British vagueness. If you actually had checkpoints on entry to the LHR perimeter roads, you'd have chaos, so of course there has to be some give and take. But why have the No traffic signs, except for access, in the first place. I may add that such signs have been there for 30-odd years - they're not recent.
