This maybe a silly question but I will ask…
I was going along the m5 and came to some roadworks, which were 50 mph average…then part way thru these particular road works there is a contraflow system, my question is, during this section is the speed still 50 for a HGV or is it 40■■
Sensible answers appreciated.
Unless sign posted 40 it will still be 50

No signs for 40…so it would be 50 all the way…?
Did it have the temporary metal barriers?
Any contraflow where there is not a physical divide will not have a limit above 40mph. If barriers and no change of signs then still 50.

No divide just cones

are you sure about that 
Pretty sure that any contraflow without a physical divide is 40 due to combined speed if there’s a crossover.
One of those things I heard a long time ago. Going to have to try and look it up now 
I see the line of thought on here…
A Motorway is a Motorway, so the 40 limit would not apply even on a single carriage road A38(M) for example. It is 60MPH limit unless signed otherwise.
So if it is signed 50, its 50.
As has been said the road remains a motorway, the fact that vehicles are travelling both ways on the same carriageway doesn’t stop the road being designated a motorway, so the HGV speed limit remains at 60mph or less where signposted, in this case 50mph.

Would that mean if the same happened on a dual carriage way the situation would be different?

If a dual carriageway has a carriageway closed and a contraflow on the other carriageway, it’s still a dual carriageway and the HGV speed limit remains 50mph unless signposted otherwise.
