I will always default to lane 2 in the D/C example.
... Pull that apart!
I don't think that's actually going to happen! The DVSA team that prepares the Highway Code probably doesn't frequent this forum.
Disappointing, I know. But, here's another puerile classic from the latest, 2015, Highway Code:
Page 45, para 134, Multi-Lane Carriageways..."In congested road conditions do not change lanes unnecessarily"
. Let's examine this piece of advice and see how it serves to improve driver behaviour and make our roads safer.
Let's first pose the question... who will be deciding whether it's necessary or unnecessary to change lanes? Of course, It's the driver of the vehicle which is changing lanes who will be making the decision as to whether the lane change is necessary or not. So, unless the driver is mentally deranged, and, yes, I know some of them are, then if the driver changes lane he's always going to deem that it was necessary because if he thought it was "unnecessary" he wouldn't have done it! Which means that, if asked, every driver who changes lane will answer that it was necessary. The conclusion that can be drawn is that there are no drivers who change lanes "unnecessarily", so why include this piece of advice! So, without the Highway Code citing specific examples of when it's "unnecessary", which it cannot do, the exhortation in para 134 is pointless.
It's no wonder the Great British public doesn't bother to read the Highway Code.
