Speed limit question

[J500ANT]

Say (as I was today) you're on a dual carriageway in your car and for whatever reason one lane was coned off (but no roadworks speed limit posted), does that road then drop from 70 to 60mph?

Doesnt really matter - just wondered.

Without a temporary speed limit...the limit remains the same. I believe that's correct.

Correct!

What do you consider a dual carriageway? As far as I know it means two separate carriageways (duh!) carrying traffic in opposite directions, rather than one shared one. The distinction seems to be that there is a curb or barrier between the two. I'm not quite sure what happens when the two carriageways diverge into two separate one way roads (e.g. a big cloverleaf junction), does anyone know whether a one way street still counts as DC from this point of view? When do two adjacent one-way roads count as a DC?

And what about single lane 60's do these go up to 70 if there's an overtaking lane.

Still a dual carriageway

No it doesn't

When the road (as defined in the Highways Act 1980, or the Roads (Scotland) Act 1984, it includes the footways, verges etc) is made up of two carriagways divided by a central reserve, all within the boundary limits of a single road. Technically, if there is a bit in the middle that isn't "reserve" or "verge" then its not a DC any more.

No they don't - it's not a dual carriageway.

Nope, not without a "construction" between the lanes, ie grass, reserve etc. White lines don't count.

not sure if there is any A road like this, but in the case of the M62, where it has a big wide divide with a farm in the middle. if that was a dual carriageway A road - would that then be two one way roads?

Now that bloke must have been one stubborn bugger

All speed limits are temporary

Not quite - without a Traffic Order and signs bounded with red circles the limit does not change.
Temporary 'speed limits' (without red circles) are only advisory.
