What should happen when a speed limit changes?

[ging84]

Have just discovered that over the weekend some new speed limit signs have been put up in my area changing a roundabout from NSL to 40 and a section of dual carriage way from NSL to 50. Now i can't really complain about this, after all it must all be part of the great progress brake are making trying to solve unemployment by winning back the jobs for the men with red flags, but it was my favourite little spots for a nice blast of power.

Now my question is how quickly do the new limits come into force, and should there be signs for the new limits?
It's a road i have been using daily for many years so do not really look at the speed limit sign, and i very much doubt i would have noticed them for some time if it wasn't something my gf mentioned over the weekend because she saw them putting up new signs

Date new limits will come into force will be the date of the Order.

It has been known for LA to put up a sign "New Limits in Force" but I understand this is not mandatory.

I'd work on a if the signs are up they are liable to enforce them, there is likely to have been stuff in the local paper etc. after all even if teh order says they come in on Monday and you were caught on Sunday would you know or be bothered to hunt down the paperwork to prove the limit was legit?

You say it's a road you use often. Just out of interest, how many accidents/deaths have there been on that road in all the time you've known it?

None which involved me

According to crashmap.co.uk
2 serious accidents on the dual carriage way 30/11/2008 22/12/2008
and one on the roundabout 05/03/2005
it only has data from 2005-2012 - 2013 figures not published yet

so unless there was any last year there is little on that basis to justify it

but to be fair it is a reasonably justified change, most drivers don't seem aware it's national speed limit. So if i do try and go for it when there are other cars on it, there often ends up with a massive speed difference, at least now there is a 50 limit sign there is a chance that it will speed up the majority of the traffic not slow it down

I think there is as much in the issue of drivers not properly understanding the NSL sign as there is with speed limits being reduced. For example, in Leeds, coming off the Stanningly bypass (NSL dual carriageway), you pass '40' signs just before the roundabout. If you continue straight across onto the Leeds Ring Road (heading towards Horsforth), you pass 'NSL' signs as you exit the roundabout. Yet every single time I'm in a queue of traffic still doing 40mph. If the train is doing 45mph, it slows to 40 in a slew of brake lights as it passes the two speed cameras. People either don't see the NSL sign they passed 30 seconds earlier, or they don't understand what it means.

I would rather they made it a 50mph or 60mph limit so it could be signposted as such and encourage people to speed up a little.
