I don't think I understand. A traffic sign such as this
https://en.wikipedia.org/wiki/Snow_tire#/media/File:CZ-C15a_Zimn%C3%AD_v%C3%BDbava.png
just says "winter equipment required". It's implied that the driver is
supposed to know (or look up) when the requirement applies. There's
going to be more signs at high-altitude roads and fewer to none in the
lowlands. No matter what the road's altitude is, it's always the
winter season when the winter equipment is required, not any other
season.

If the sign itself specifies a time range, then it makes sense to tag
that, otherwise I see no point.

If a country has a blanket rule that during such and such period all
vehicles on all roads must have winter equipment, there aren't going
to be any signs at particular roads, hence no tagging at all (we're no
tagging legislation).
