Saw a similar thing on the M20 last week around Maidstone in the variable speed limit area the traffic heading up to London was heavy and all four lanes going at the same speed yet the speed camera in the third lane was flashing like mad while none of the others were perhaps the camera was bored and felt it needed to do something
It flashed when I was going past last night at 28, but I think it covers both sides of the carriageway. So it could have been someone else triggering it, seemed to be the case last night anyway.
There’s a red light camera on a41 heading into central London that flashes when no vehicles about. I was sat at opposite lights and noticed it! Does that mean it don’t work!
I went through the same speed camera on sunday night 15/9/13 was doing 27 mph and it flashed twice but there was a car travalling in the other direction seemed to me he was speeding
