i’m watching a thread on another site ( vastly inferior) 
anyway the jist of the topic is whats the speed limit on
a single carrige way A road( two lanes no center res ) with a posted limit of 50 mph
for an artic
i know what i think and without driving to work to get my highway code i’m flummoxed
i’m sure that here we have the knowledge
i’m sure that theres at least one instructor on here
40mph
Am I missing something here?
If the posted limit is 50 then the max. speed limit is 50mph (up to 71/2 tonnes)
No central reservation means 40.

40 mph for an artic (as it’s over 7.5t), posted limit is irrelevent in this case.
I’m surprised you even asked.
It would still be 40 if it was a 4 lane stretch without a central res.
I know plenty that’s been caught out!

No need to drive to work, the Highway Code is right HERE.
Awkward question now 
, what is the definition of a central reservation?
Does there need to be a crash barrier, or can a raised kerb or patch of grass alone be defined as a central reservation?
I know its playing with words but if it stops the collecting of any more penalty points it’s a valid question…

On a two laned ( or more ) stretch of road the authorities state there must be a barrier before it becomes a dual carriageway, raised kerbs or grass verges do not count, therefore if you are doing above 40mph without a barrier keep your eyes VERY peeled, favourite locations for mobile cameras throughout the country

The definition of a dual carriageway is when the two directions of traffic flow are physically separated by a central reservation, also know as a median strip. This can be gravel, grass, a rasied kerb or concrete divider, or barriers. Anything more than paint in other words, if it is just painted lines then it is a single carraigeway.
Keep your eyes peeled when on the road and you will see the familiar Dual Carriageway signs when the central reservation is just gravel or grass, with no barriers.

I hate to disagree but I once got a ticket for assuming just that!
I took it to court because I thought that way and I ended with even less in my pocket, ignorance isn’t bliss
Well that is the definition and there are countless examples on the road network, so there must have been something else involved in your ticket, or you were wrongly convicted.
Just a quick search turned up a couple of sites that explain what a Dual Carriageway is.
HERE in a question about the A556 and HERE from a learning to drive web site.
From a site for British road enthusiasts www.cbrd.co.uk there is THIS definition of a Dual Carriage Way.

40 mph. But more than likely they won’t do it unless there are cameras 
I always stick to the limit. It’s not worth my driving license. The only time i have ever speeded is by 2 to 4 mph. i think “Sod the ‘rushing-rep’ behind me”. Then again none of our loads are really all that time sensitive. I suppose it would be different if they were.

theres not a road anywhere on the uk network that has speed limits posted percifically for hgv’s, think your spose to work that bit out for yourself.
Last Friday evening travelled from Norwich up to Cromer with a big 40 mph tail and when some oick in a Mondeo finally managed to flash by me I could tell he was upset, blowing his horn and giving me the finger gave the game a way. LOL

You’ll also see on many places with a grass reservation and no barrier, at the end of the grass reservation you will see end of dual carriageway signs.
If however you were caught doing 50 on a stretch of dual carriageway (in a town say) with a 30 or 40mph limit…

I was on one today, heading toward junction 1 of the M40 from Maple Cross/Denham. Dual Carriageway Ahead signs, no barriers just grass separating the two carriageways and signs facing the side roads with arrows pointing left and ‘Dual Carriageway’ signs below them. National Speed Limit signs at the side of the road.

I’m fairly sure there was such a sign on the A75 (Gretna - Stranraer) last time I was there. Maybe one of the regular A75 racers could tell us!!
