Bit confused about this.

Been around the west part of the M25 today. Coming back this evening there was a reduced speed limit on some gantries to 50mph. However, after a few gantries with the lower limit, there wasn't a reduced speed shown anymore and no nsl sign. The gantries weren't lit.

Once I had cleared the first clear gantry, I sped back up to 70 mph. I didn't see an nsl sign at all on any following gantries. Was this the right thing to do are am I now getting a ticket?

You could see it was confusing some people as earlier today, when the reduced speed ended you passed gantries with the nsl sign on. Tonight, there were no gantries lit with the nsl sign after the the last gantry with the lower limit.

Does the reduced limit only apply to gantries that are lit up with a lower limit? I obeyed all of these. What signifies the end of a reduced speed limit?

Anyone able to clear this up? Thanks.

Oh dear. First ever speeding ticket on the way for me then.

That's me and loads of other drivers screwed. I was one of the last to speed up. Everyone was doing it.

There wasn't an nsl sign at all after the last 50 limit sign. In fact, there was nothing until we approached another 50mph sign a while later.

There were multiple junctions onto the M25 too and the gantries near then weren't lit either.

Once you pass a junction / joining slip road and there isn't a repeater, then normal motorway speed limit resumes. Cars joining from the slip road have no way of knowing that a reduced speed limit was in place on the motorway.
That's what I thought. Hence why I sped up. I travelled miles without seeing a repeated speed limit sign.

Road works are the worst for this. I have seen plenty of the temporary 50 mph signs (the type with sandbags to weigh them down), but still the uncovered NSL signs.

OP was it red-ringed or just an ‘advisory’ speed limit?
Red ringed.

I travelled from the M3 junction to the A1 junction. The incident was just after joining the M25. There was another further along but I passed lots of gantries and a few joining junctions that had unlit gantries.
