For marking of roads where transporting of hazardous materials is forbidden - or designated if such signs did exist.


Roads where transporting hazardous materials is forbidden can be tagged with hazmat=no.

Where local authorities divide hazardous materials into several groups, they might be appended with a colon, e.g. hazmat:A=no

Such divisions can be described on this page (on a per country basis if variations exist).


As with any access=*.

Country specifics


Use hazmat=no, but hazmat:B=destination - the auxiliary sign "VAK(B)" allows the transport to destination on that road, despite the name of the main traffic sign. Some places have a hazmat=designated to divert such traffic onto motorways.

Groups A and B exist. Their difference is (mostly) only in the amounts allowed, as defined separately for some 10 material classifications. Group B allows more of the materials. That is, for example less than 50 kg of explosives onboard is not a hazardous transport (by the signs, that is), any transport of 50 kg or more must obey they signs for group A (hazmat:A=*) and a transport of over 500 kg belongs to group B (hazmat:B=*).


In Germany exists a positive and negative network for transporting hazardous materials. Other streets should only be used to reach your destination. In water protection areas you can find special signs to protect water against contamination. For this we create a special subclass hazmat:water=*.

hazmat=designated Driving with hazardous materials explicitly encouraged (DE:Grundnetz Gefahrguttransporte)
hazmat:water=permissive Drivers of water contaminating materials should use a other route.
hazmat:water=no Driving with water contaminating materials forbidden.
hazmat=no Driving with hazardous materials forbidden.


L'utilisation frequente est hazmat=no.

(gas or volatile liquid) D, E and dangerous goods without tunnel restriction code. France, A43, Modane-Bardonnechia(it), Frejus, code C, Note: Required escort for ADR classes 1 and 2.
