It's voluntary, at least the one I'm in is. If you can you can, if you can't you can't. Simples. 

I took my cruiser out about 3 years ago - I was headed to Deddington for a meeting - I found a bunch of back roads and the truck felt really planted with very little slide. I've always had ordinary road tyres as I've never off-roaded, so took it fairly steady.
Earlier in the week, I was getting all excited to think I'd have the cruiser out in the snow by the end of the week, but it's raining right now and looking on the Met site, looks like East Anglia / East Mids misses out again![]()
Boo hoo, that's a shame Nathan.
We'll have this lot for some time, the forecast is sub-zero every day (except Saturday +2C) then it goes back to -6C daytime high and -11C nightime low, with more snow on Tuesday - Friday.
incredibleA little curling…Montreal style…
