In germany the countys publish a positive and negative network of streets which
may be used for ADR transportation (Gefahrgutstraßengrundnetz).

I used this to at least tag all roads in my county with
hazmat=designated/no/destination.

I havent seen any further classification in those documents.

Sounds reasonable. As this seems to be country specific it might make
sense to clarify in the wiki for which country this applies.

I'd do so - hazmat is a very rare tag so adding more
information/clarification/proposals would be a good thing.
