Learn to "ghostride" the Zed.
On my trip back from Germany to the UK, I got coaught in the worst of it and it took me 18 hours to get back.
Stick the Zed in 1st or 2nd, then gently lift the clutch, no throttle, maybe feather the clutch till you start moving.
Once moving, resist the urge to step on the throttle, just let the Zed "ghostride" itself thru the snow and ice.
+1 if your driving in snow/ice its not a race. you will see most cars (fwd) pass you but dont try to keep up as you wont. Also if you know the route then slow down early and use your brakes like there is an egg under the pedal. dont press hard enough to activate abs or you wont stop. Use more of the lane also as it gives you more room for error.
For the record, i do know about this and while i am in no way a driving god, i am not a driving 'tard either. I was at my parents house where the snow on the road was about 20cm and with then zed's ground clearance i think i am justified in using the term stranded!
What you on about? I was just saying it, its general advice for everyone and anyone who doesnt know.
