Has anyone seen this before and have any clue what it's about? I had this earlier this evening for about 5 miles around junctions 28-29. My first thought was that it was genuine, but then saw that the other carriageway had the same signs. Surely there can't have been "oncoming vehicles" on both sides at the same time?
Given that the gantry signs are enforceable I felt I should comply, though few others were. After a while I took to speeding up between gantries as its hard to drive on a fairly empty motorway at 20mph when other cars are passing by much faster.
All in all, it seemed very odd. There was no sign of an oncoming vehicle on my side anyway. So maybe a bizarre controller glitch? A google search doesn't shed much light, though it does appear to have been mentioned some years ago on a motoring forum.
