The Highways Agency seems to think it can dictate to everyone.
If you have an A road through your town / village, you cannot put up posters on lampposts (they're removed), plant bulbs alongside the road (might distract drivers to see a few daffodils), or erect A-boards outside your shop (blind people might bump into them). We were even told (not asked) to remove an A-board from a patch of our own grass because it was obstructing the pavement (there was no pavement). And yet they can put large numbers on every lamppost, which ruins the look of our picturesque High Street, to enable them to check the lights without stopping.
There is no arguing with them. They will not listen to reason or common sense.
Someone needs to give them some boundaries.
Why is this idea important?
The Highways Agency's intransigence reduces the activities of communities, and make traders already difficult lives even more difficult. A-boards are a vital source of advertising to many small shopkeepers. Posters on lampposts are often one of the few ways that local groups can advertise their coffee mornings, bring and buy sales, etc. Visitors to a town cannot find out what is going on easily.
There is also nothing wrong with flowers along the roadside!
No-one should be able to so completely ignore the wishes of local communities.
