To make progress, can I legally.....

[Bayeux]

Move around cars stuck in snow on a motorway using the hard shoulder?

I'm talking about cars which are unable to move.

I don't really want to sit behind a load of cars who have no grip and can't move when I can on my winter tyres.

So, if there is no other clear route, can I use the hardshoulder and then move back over asap?

I don't know but I'm going to guess "No". The reason being that although you believe you're super elite with your snazzy tyres, if (heaven forbid) you DID get stuck, then emergency stuff won't be able to get through.

Not legally

Only if directed to by the police.

What if you get beside them and get stuck, (or someone else sees you do it and get's stuck trying it themselves).... Then the shoulder is blocked.
