Just a quick heads up for those that may not be aware.
From today (6 April 2015) HGV's can now do 50mph on single carriageways and 60mph on dual carriageways. Be aware that a gap you may previously have pulled out in could be closing much faster than before.
Where did you get this info imax?
I drive trucks for a living and it's never been discussed by anyone of authority, only thing we know for sure is that hgv vehicles can now do 50mph on the A9 stretch from Stirling to Inverness as they have introduced average speed cameras, all be it, they were only meant to be doing 50mph on dual carriageways anyhow
And also on that point, I only do 40mph while in my truck on single carriageway carriageways and 50 on dual but there are plenty that pass me, not all of them safe, come to think of it, they are all breaking the law if they do pass me as I'm at correct speed. :-P
