M4 Westbound Average Speed Cameras

[starmonkey]

Has anyone else noticed after the 50mph limit enforced by the average speed cameras westbound near Reading you get the National limit signs and End of roadworks signs but further down the road there are more average cameras?

These ones don't have signs saying not in use, but neither are there any roadworks or other limits in place.

There is a national limit sign under each camera but its only on the inside lane side of the carriageway. Anyone know if these are enforcing the national limit and if so do they only need to have the sign on one side of the carriageway?

If you mean the roadworks around junction 10 at Reading, there are no cameras monitoring these at all, let alone SPECS.


Further west, a number of SPECS have sprung up in preparation for forthcoming roadworks. The idea of a NSL sign underneath them is to remind you that there is no lower limit in force. This doesn't, of course, stop some tossers seeing them at the last moment and dropping anchor

They are not enforcing the NSL, they are awaiting the start of roadworks
