Legal process to change 40mph limit to a 30mph limit?
Discussion
Our local facebook group has a message regarding (home-made?) signs that have appeared on a road with a 40mph limit, saying that a 30mph limit is now in force.
While these cannot be legally enforced, as the circular 40 signs are at either end of the road, there is talk of how a road can arbitrarily be changed. I thought there had to be specific reasons for a road to be a 30 vs 40 e.g. house driveways, with dropped kerbs directly opening into the road. Does anyone know the rules around this?

Is the sign on a new streetlamp? And there's another streetlamp on the other side of the road, less than 200 yards away?
Presumably 40mph repeater signs are in place on the series of streetlights spaced at less than 185 yards (IIRC) to remove the national 30mph restriction and to back up the 40mph gateway signage?Or has someone removed them but left the 40mph gateway signs?
The Traffic Regulation Order (TRO) process (with consultation period) would need to be followed for any proposed speed limit change.
The local Highway Authority would be able to confirm the TRO/limit that is in place, and may have an interactive assets map on their website that may have a layer for speed limits.

I'm no expert, but I recall a traffic regulation order requires consultation.
It was the route protestors/ residents took in Lambeth to get a low traffic neighbourhood quashed by the courts.
Here's an example near me of a 40 dropping to 30, though it was national highways rather than tne council

So the process to do this would definitely involve a paper trail at your local council, and would not be "arbitrary" as such (though i appreciate some people who don't agree might see it as such).
Those home made signs are (to me) akin to those fake speed cameras people put up, and are only one notch on the dial away from people leaving wheelie bins outside their house to protect "their" space.
It's a slippery slope...
