Bypassing traffic lights using filter lane and U Turn?

[SimonSh]

There is a junction on the A5 at Weedon where if you approach to cross the A5 from the M1 towards Daventry on the A45 it is possible to take the left hand filter lane to head South on the A5 and then immediately do a U turn then taking the left filter lane again to continue along the A45 having avoided waiting at the traffic lights.
My son was stopped by the BIB after pulling this manoeuvre although they did not do anything other than check his car etc. etc. and this is probably because I have set a bad example by doing the same myself at this particular junction

I would not pull this move during a driving test, advanced or otherwise because it stinks of impatience and may be seen as "queue jumping" by other drivers but what are others views on "making progress" in this way??

Can these three threads be combined, please, mods??
