Misinformation!

One annoyance of motorway driving is when the 40mph warning signs come on, last for about 5 miles, and then stop without any noticeable traffic build up, accident or anything else. It does undermine their effect if it happens too often, as drivers start to doubt whether the warnings are accurate and don't take as much care as they should.

Different place but same issue. The electronic traffic sign on the A13 opposite Chalkwell Park is still warning of traffic build up due to Village Green. Now I know that Village Greèn finished over 10 days ago because I was there.

If these signs are going to work they have to be up to date but rather more to the point doesn't anyone check them on a regular basis?
