Can someone enlighten me? Four times in the past week I have used the M42 on journeys to a from Derby, three of those times have been very late at night when some of the signs have indicated 40 and 50 MPH speed restrictions in what seems to me quite a random order.
On those three times there have been no accidents, no workmen at work, no cones (I’m specific here as we all know that cones don’t mean work is actually going on!) and no police (if ever) around. Why then are we told to keep to 40MPH when on one night there were only four other cars within 100 metres of my car?
On the forth time it was a Sunday afternoon and they were again at random speed settings of 40/50/60 MPH. I would agree that perhaps they are needed at some points on the M42 when the traffic on a Sunday can get in my opinion busier than a week day.
However, it seems that there does not seem to be any logic to their use. Perhaps the controllers in their little boxes have nothing better to do than try and set speed traps for the unsuspecting motorists. I can’t think its about safety when its 11:30 at night and the full moon is out and there’s not another car to be seen for some distance. Still it takes all sorts I suppose.
