You'll see 20mph marking on the road surface but zoom into the central reservations and you'll see 40mph on the first lamppost and 30mph on the next.

Where is the logic!?
Is the 40 a repeater and the 30 (bigger sign ?) a 'change'. Even then, there is an inconsistency between the 20 and the 40.

A329m/A3290 has been reduced to 50mph along entire length, appears to be temporary but no signs of roadworks etc.

I wonder what the speed limit is here?

30 at the welcome sign
https://www.google.co.uk/maps/@55.69816 ... 312!8i6656
or 30 at the roundabout

I love to use google map to find a cool thing.

30 from the first sign. Interesting is that both have a national speed limit sign on the back, so there is a short length of carriageway with different limits in each direction.

I imagine this is from the local council's department of "not my job guv", who have sent a team to put up new signs, but not to take the old ones down.

I have seen another single carriageway somewhere were the limit in one direction was different from the other for a short distance. Can't remember where it was though :?

The A140 in Suffolk forgets that NSL should be 60mph for its entire length - other than through villages.

The entire road is a depressing trundle if truth be told.

Suffolk has quite a few of these low-speed "trundles". A134 from Bury St Edmunds to Sudbury has also been lowered to 50 for most of its length, plus villages of small size get 30 or 40 limits, often extended some way beyond their boundaries regardless of the quality of the sightlines. It's actually doubtful that much of the road *could* be driven at 60 even if NSL were to apply, but in that case there would be no signs suggesting that any particular speed was definitely safe, and drivers would be encouraged to drive to the conditions.

I think the best solution to this general problem is to give warning of a future speed ilmit decrease, without actually reducing the limit. Place a "the limit will be 30 in 300 yards" sign, likewise for 200 and 100 yards, and then place the speed limit reduction in the expected place, which should be just where the houses start. (If you're worried about compliance, you can place a speed camera at the very start of the limit; given the amount of warning, there's no excuse for still going too fast by the time you ge there.) This means that drivers can do the buffer-zoning themself in a reasonable way, and yet aren't forced to go too slowly while they're still a long way from the built up area.
This system is used widely in rural areas of Scotland. I can't think of any examples in England and Wales, and I have no idea why it is not used here, as it makes far more sense than the alternatives.
These signs will be a problem when we have compulsory camera governed speed limiters in cars.

Because it's a country lane, probably. The NSL signs just mark the end of the restricted road area in the village centre. Now the houses beyond the NSL signs look quite modern, probably post-dating the order for the 30 limit, so maybe there's a case for extending the restricted road to the current edge of the development, but that's up to Dorset CC.

Most of that lane is marked as a BOAT on the OS mapping (and probably unadopted) hence the NSL signs. It's a decision for Wiltshire Council rather than Dorset Council though. (Dorset CC is no longer)

Apologies, mixing Shrewton up with Shroton. However, there is still a Dorset UA covering most of the former Dorset CC area, and I bet most of its inhabitants think of it as the "county council".

It's not good practice to have NSL visible in the distance before entering the speed limit.

It seems a bit daft to me that there are 2 houses quite close to the road beyond the NSL sign.

Those signs are reasonable.
NSL is used where the road has been designed to take traffic at 60/70 MPH, or when a road doesn't warrant its own bespoke speed limit (for many factors).
If on the last example you didn't have those terminal signs, then that track would be limited to 50MPH (where it is a public highway), 50 MPH limit would mean it is suitable to drive upto 50 MPH for the majority of that section, NSL in this case means road is not really assessed to have a maximum speed limit, drive up to a speed that you think is safe (but don't exceed 60 MPH). Therefore terminal signs are used at the junction, also its useful for those leaving a property on that lane.

It's the same with Chapel Lane, just put it as NSL, instead of faffing with putting in a TRO and 30 repeater signage.

I am pretty sure it was explained on SABRE once by someone, but the default limits are 30 in a built up area or NSL.

Any deviation from these there has to be a reason, however I stand as always to be corrected.

On a restricted road the speed limit is 30 mph unless changed by an order.

A restricted road is one with street lights located at most every 200 yards (England and Wales) or every 185 metres (Scotland and Northern Ireland).

That is what makes the national speed limit 30 mph in a built-up area.

Although orders can derestrict roads with such lighting, restrict ones without such lighting, or apply 30 mph limits to unrestricted roads.

And I'm fairly certain that in the 1930s there were only two options available - 30 for restricted roads and no limit at all for derestricted roads. There was no in between 40 or 50.
