Speed limit dual carriageway question?

[badger]

could be well off the mark as its more years than I care to remember since i had to pick up the Highway Code.[/size]But I always thought a dual carriageway was 70 so long as it had a Barrier central reservation.If not its a 60.


If the  dual carriageway is sign posted with national speed limit signs then it is 70mph whether there is a barrier or not. [if you are in / on your car / bike. if you are towing in a minibus, van , lorry etc then it is 60mph.
Confusing if you have several different modes of transport !!!!! :\

It doesn't need to have a barrier, as long as it has a central reservation, it's 70 unless the signs say otherwise.  Same with 30 limits, if it has street lights and no signs to say otherwise, it's a 30mph zone.

As for the idea of lower limits by T junctions, that applies in some countries.  In Poland the speed limit on a single carriageway is 90kph except for 200m either side of a T junction or pedestrian crossing where it drops to 60kph.  So when you are clocked doing 99kph as you enter the 200m to a T junction zone, it costs you 100 Zloty (which at nearly 4 Zloty to the pound, I thought was quite a bargain, no points either!).

So I can fly past a T junction on a dual carriageway at 70mph, and not get flashed?????

Yes, of course.
