Was driving down the M1 earlier. I was doing the speed limit, my car has the cruise control that attaches to the sat nav / road signs and keeps to the limit and changes when it does. I was approaching a variable limit gantry and it was showing 60. I started to manually change the limit on the cruise because the system only slows once its passed the sign and I could see the yellow cameras to the left of the gantry. About 100 metres out the limit on the gantry disappeared. Wasn't replaced with NSL, just vanished. So I clicked back up to 70 to engage the auto limit. As I went under it flashed, it could well have been someone going to the other way, its hard to tell. I never passed a sign saying 60 so as far as I understand I was doing the correct speed

Im not bothered because even if it thinks the limit was 60 I was only 10 over (probably couple under as it was indicated 70), but Ive driven for nearly 30 years and never had any points nor had to attend a SAC (Im not be holier than thou, have frequently pressed on above the limit, just never been caught), would hate to have that record tarnished.

Will I see anything by way of a NIP and if so do I have a chance of saying I did nothing wrong?

Not the same though as the OP in that was breaking the limit whatever it was. I wasn't if NSL was in force which I am assuming it was

Blank sign doesn't mean NSL. See other thread for discussion of why.

I CBA to find this but I remember reading something about when the speed limit changes there is a grace period iirc 30 seconds before tickets are issued.

If you haven’t previously passed a reduced limit then of course a blank sign means NSL.

We have had this before. I asked Highways England. They responded, that until another limit shows or an NSL sign shows, then the prior limit displayed is still in force. An image taken should include the active displayed limit that is on that gantry to verify it.

But is the limit in force before or after the sign? Because I never passed a sign < NSL. If I'm driving on a b road at 60 NSL and approach a village where it's 30, surely it's not 30 when I see the sign, it's 30 when I've passed it.

This was my situation. I'm at 70 NSL on a motorway, ahead I SEE a 60 sign, then before passing it, it disappeared, so I was never under a 60 no?

I dug out the email (from 2018, mind you)
Their reply was:

"Thank you for your email to the Highways England customer contact centre on 28 August about speed limits displayed on smart motorways.

The simple answer to your question is that there should be an “End” or NSL signal displayed at the end of any reduced, variable speed limit. We are aware, however, that there are certain times and locations where this is not the case and our technical teams are working to apply a solution to resolve this issue.

From an enforcement point of view, the speed cameras can only enforce at either the speed limit displayed or, where no limit is displayed, the national speed limit and this would apply to the above scenario also.

Thanks again for your query. I hope that the above answers your query but if you need any further information please get in touch using the below contact details."

What about where you pass a gantry with a sixty displayed, and then the next gantry has no limit displayed? Is the limit still sixty? And if you exceed this, how can they take a photo of the displayed limit if there isn't one?

See my second post. You then know as much as I do.

my bold

So they are aware that 'there are certain times and locations where (there is no 'end' or 'nsl' sign,)' and their technical team 'are working to apply a solution'! (Seven years ago!)

They also say the cameras can only enforce limits displayed or the nsl. As far as the op is concerned, no limit displayed means cameras can only enforce nsl. I don't think the op will get a ticket.

The OP didn't enter a limited zone so won't get a ticket.

The limit starts at the sign.
When you get close to the sign and keep looking at it, the image on the sign will look like it disappears. Perhaps this is what you have noticed.
The LEDs are behind an aperture that restricts the direction of the transmitted light. You can’t see the sign when you are close to it.
Perhaps you could try that to defend a case if you were caught exceeding 60. However, you can read a speed limit ahead from about 500m. At 70 mph you have 15 seconds to note the limit. Leaving it to less than 1 second may not fly.
Good luck.
