I KNOW (and I rather suspect you do, too) that the MUST NOT is
qualified by the concept of "except in an emergency" - and it is THAT
qualified requirement that I was (and still am, since you have declined
to answer it) questioning on how loosely you interpret "emergency" if
it can be defined to suit YOU.

Oh, I see. The goalposts are moving a bit fast for me this time of the
morning. If you want to start a debate about "what is an emergency", and
my interpretation of that (rather than the "Do Not" paragraphs of the
HC, which is what I was taking about) then go ahead.

My own definition is "car has broken down/struck an object in the road
etc, or the road has become impassable; (so as to reach an emergency
phone). And for completeness - if instructed by emergency services".
Even then, I'd be very wary of walking *along* a motorway, rather than
away from it.
