Uhm, it's less than general, but sometimes obvious in context. In my part
of the world, a seasonal road is one where they don't trouble to plow the
snow. Sometimes up in the peaks, that means the road will be impassable
from mid-October to mid-May in a severe year. However, most of the seasonal
roads are posted "open April 15-October 31" but in practice they will open
as soon as they can get crews in to clean up the inevitable spring rock
slides and stay open until there's too much snow for a police car.

I have no idea how to encode all that in tagging. It depends on the weather
and the judgment of the highway department.
