Repeater signs on restricted dual carriageways

[essayer]

This over near Bicester is a 40mph dual carriageway


imo 40mph feels slow for that road, and the signs are sparse and oddly small, so if you're not a local it's easy to get caught out


What are the rules regarding signage where a DC is reduced down? Do they have to be both sides of the road, and is there a specific interval they must be spaced by?


The entry to the 40mph is back here

First repeater
https://goo.gl/maps/zPRX1QPye5ocpfhS8 - both sides of the road, although a bit small

Second repeater after ~350m and TWO sets of traffic lights
https://goo.gl/maps/mPJD6b3YwJqSJTPB7 - the NSL sign applies to the access road to the garden centre - there's no 40 on the other side of the road

Third one is before the layby itself

Thoughts? To not have a repeater after two sets of traffic lights seems a bit amiss.

You'd expect a reapeater sign after the second set of lights for the benefit of those joining from that premier Inn?

Yeah that's weird, from that direction - wouldn't you then be driving at 30? No streetlights, but no national speed limit sign either. Seems inconsistent.

Some of those shots have streetlights, which would mean the road is 30mph unless signposted higher for one. I've not looked all of them

You should have a large sign at the start and then repeaters at regular intervals depending on the speed. There was a change that reduced the need for repeaters to try and cut down on clutter however, I can't recall if that was just 30/40 mph type zones or just where the speed limit was higher than the default if not posted. ie if the streetlghts are there its by default a 30mph zone, and the speed limits mean its higher at 40. The absence of repeaters that may cause uncertainty should result in drivers using the default lower speed which is deemed safer

I don't make the rules before someboidy starts saying "that road looks safe" etc etc...

After the traffic lights, the streetlights stop - the DC continues then there's about 150m before the repeater, which is pic #2 in the OP (offset at the entrance to the garden centre). Even that one's not very clear especially if you've got cars slowing to enter the garden centre. Seems a bit unfinished to me.

Since 2016 there has been no requirement for authorities to place repeater signs, although of course many do.

I was told (on a SAC), that the reason for the reduced requirement for repeaters was that people were stealing them for birthday celebrations 40, 50,60 years old etc. So to ensure stolen ones did not reduce the roads legitimacy with regards to signage, the number and spacing of repeater signs was reduced. The same with start of limits, one only needed. Although I believe the general recommendation is to keep the original spacing and numbers. Sounds plausible, whether that was insider gossip, or proper knowledge.
