50 MPH.
A truck is limited to 50mph on a DC unless signs show a lower limit.
Mikey. I’m confused.
Why do you NOT think its a DC?
It has a physical separation between the directional flow of traffic. Therefore it is by definition a Dual Carriageway.
ETA… The section of road the vehicle is on is DC but the piece of road further up with the right turn is SC without a physical barrier between the directional flow of traffic
.
Mikey D:
Well i think its 50 mph ,my reasoning its a dual carriageway ,but with the other carriageway on the rh side hidden by the hedgeMind you having looked at the road sign ahead ,im not now convinced it is a dual carriageway
, so 40 mph
ok im going with 40 MPH
i think
cheers Mike
so, if it is not a single carriageway (as there are no lanes for the other direction), and you don’t think it is a dual carriageway, then, can you please try to explain what type of road it is?

actually, the road where the turning is, is still a dual carriageway, it turns to single carriageway about 100 meters after the turning

50 MPH.A truck is limited to 50mph on a DC unless signs show a lower limit.
are you sure it is a DC, as there is only 1 lane?
Hmm. Guess it could be a slip road.
On the face of it, there is no way of telling what the road classification is.

since when do slip roads have right turns directly off them?
There is a sliproad that goes under a bridge and also continues on into the village. I am trying to think where it is.
Yesterday I was on that road, doing 50… in a mile, I had 3 trucks overtake me… and let 'em get on with it… but I just wonder sometimes why I make an effort… I was on a SC this morning doing 40 and I had a wagon without a trailer fly past me… must have been on the limiter, 50 posted limit… just wonder sometimes why I bother sticking to the proper limits… If I wanna go fast and overtake everything on the road, I take the bike out… but in the wagon, I behave myself… all the time… and I would expect other truckers to do the same, but I’m starting to think otherwise…
merchantofdoom:
One of my mates got done for doing 50 on a dual carriageway where they’d shut the inside lane for road works.
More that likely it was a single carriageway with two lanes or a lower limit in place.
The difference between a single and dual carriageway has nothing to do with lanes, it’s if it has a central reservation or not
And they wonder why compulsory DCPC training was imposed on us…
another one for the newbies, what is the speed limit for this road for a truck?
and please explain your theory of your answer 
I’ll bite, thats an SC so 40 for trucks.
Its a 40. No physical barrier.
As it is a single carriageway it could be 50 or 40, depending on the MAM of the truck in question…

Not necessarily, a Single Carriageway can be separated from traffic flowing in the opposite direction (and also a Dual Carriageway can only have one lane). A Google map reference would be helpful.

I agree an SC can only have 1 lane.
But are you sure about your theory of a SC being separated by a physical barrier.

I’m not sure about that either, a physical barrier means dual carriageway AIUI.
