For mountain pass in Alps, this could be just access:conditional = no @ Nov-Apr
That seems logical to me. One word on using "access:conditional" though - this would indicate no access, including on foot.
In somehow, we may consider that the road does not exist in winter due to the large amount of snow over it. I mostly use it during ski touring.
For more details see [1] and [2]. Essentially there is a hierarchy of subcategories for transportation modes. [2] http://wiki.openstreetmap.org/wiki/File:Access_hierarchy_simple.png
This scheme should be more wildly used. It seems to be use only in the German wiki.
