This popped up this morning in the reading list on the BBC news website; I then realised it was from Dec 2012.
http://www.bbc.co.uk/news/uk-20851775Has anyone seen these deployed anywhere? It would be interesting to understand the advantages of preventing rubberneckers (assuming drivers don't rubberneck wondering what those big green screens are!) vs. the time it takes to get the purpose built vehicle/trailer to site, put them up and clear away afterwards...
I would have thought the 'authorities' will take more time and effort in organising and getting the screens up which would be better spent clearing the incident and re-opening the lanes/road.
I do wonder what the HA patrols are actually meant to do when I come across a closed lane or two, only to find a HA vehicle, a load of cones and a broken down vehicle they could easily have towed out of the way..!
