Speed limit dual carriageway question?

[Grahamm]

Question - what is the speed limit on a dual carriageway where theres T junctions????

Unless there's a sign showing a different limit it is, as you say, 70mph.

Of course that doesn't necessarily mean it's *safe* to do 70 there, what you need to ask yourself is "if someone came out of that junction could I stop in time?"

If the answer is "no" then by all means slow down until you're sure the junction is clear, then accelerate back to the limit.
