Lazy road signs

Motorists really do get it in the neck when it comes to breaking the rules of the road.  How many times do councils and motorway authorities get it in the neck for doing things that make it possible for motorists to break the rules? Never!! The number of times I have been driving on motorways, through towns or country roads and been faced with a road sign warning me that something was up ahead that required me to slow down.  Then when you get to the spot there isn't anything there.  I'm talking about roadworks and warning signs on motorways.  Road narrows, temporary traffic lights ahead and when you get past the signs the traffic lights are either on the side of the road facing away or there aren't any their because the lazy road workers couldn't be bothered to take the signs down after their days work.  Motorway signs "Congestion Ahead" slow down.  Variable speed limit 50 mph.  Nothing in the road no congestion so why was I told to slow down? Maybe the brainless operators in the control centre hadn't got anything to do so thought they could play with the signs.  Fog signs when you are already in a pea souper. On one occasion I could hardly read the sign because it was so foggy.  No warning before hand however.  Miles of cones and nobody working on the affected part of the road.  No wonder people ignore road signs and then get into trouble. If only people would do their jobs properly in the first place that's all I ask.
