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

Usage

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).

Tunnel restrictions

General EU restrictions

Since January 2010, a specific regulation is applied to the tunnel: There are five categories (A, B, C, D, E)

Tunnel categories The selected category fixes the list of dangerous goods whose transport is forbidden in the tunnel Transport of dangerous goods authorized in the tunnel Example
A transport of dangerous goods without restrictions B, C, D, E and dangerous goods without tunnel restriction code Austria, B171, Kufstein-Pians, Stadtberg, code A, Note: required use of warning lamps in accordance with ECE regulation 65
B restriction on the transport of dangerous goods with a very large explosion range. C, D, E and dangerous goods without tunnel restriction code. Germany, A31, Leer, Ems, code B.
C restriction on the transport of dangerous goods with a very long-range, long-range or long-range poisoning explosion. (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.
D restriction on the transport of dangerous goods that threaten a very long-range explosion, a long-range explosion or a large-scale poisoning or a large fire. E and dangerous goods without tunnel restriction code. Netherlands, A22, Velsen, Velsen, code D
E The restriction applies to all dangerous goods except: UN 2919,3291, 3331, 3359, 3373) dangerous goods without tunnel restriction code except: UN 2919,3291, 3331, 3359, 3373. Germany, Hamburg, Kronstieg, code E, Note: 06:00-21:00.

Dangerous goods without a tunnel restriction code correspond to the numbers NU 2919, 3291, 3331, 3359, 3373.

Specific restrictions

Example Tag Meaning
Hgv-conditional - flashing light.jpg hazmat=no
hazmat:conditional=yes @ (flashing_light)
Vehicles with hazardous materials are only allowed to enter when using a flashing light.

Country specifics

Finland

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=*).

France

Frequent use is hazmat=no.

The French government publishes an non-exhaustive list of tunnel here: Tunnels de + de 300 m - régime TMD - liste non exhaustive (Centre Étude des TUnel alias CETU) Most of them are groupe A or E.

Germany

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)
DE:354
hazmat:water=permissive Transports containing water-polluting substances should choose a different route.
DE:269
hazmat:water=no Driving with water contaminating materials forbidden.
DE:261
hazmat=no Driving with hazardous materials forbidden.

Additionally Germany uses the European tunnel categories A - E. Traffic sign DE:261 Zeichen 261 - Verbot für kennzeichnungspflichtige Kraftfahrzeuge mit gefährlichen Gütern, StVO 1988.svg relate to hazardous materials, most times with attachment sign DE:1014-50, DE:1014-51, DE:1014-52 or DE:1014-53 to specify tunnel category. To specify access restrictions to ways these traffic signs should be translated to OSM-tags as followings:

Sign Tags Meaning Description type of goods
Zeichen 261 - Verbot für kennzeichnungspflichtige Kraftfahrzeuge mit gefährlichen Gütern, StVO 1988.svg hazmat=no No access for vehicles carrying hazardous substances. No passage for any dangerous goods.
Zeichen 261 - Verbot für kennzeichnungspflichtige Kraftfahrzeuge mit gefährlichen Gütern, StVO 1988.svg
Zusatzzeichen 1014-50 - Tunnelkategorie gemäß ADR-Übereinkommen (B), StVO 2007.svg
hazmat:B=no No access for vehicles carrying hazardous substances
which are not allowed to pass tunnels of category B.
No transit with dangerous goods that can lead to a very large explosion.
Zeichen 261 - Verbot für kennzeichnungspflichtige Kraftfahrzeuge mit gefährlichen Gütern, StVO 1988.svg
Zusatzzeichen 1014-51 - Tunnelkategorie gemäß ADR-Übereinkommen (C), StVO 2007.svg
hazmat:C=no No access for vehicles carrying hazardous substances
which are not allowed to pass tunnels of category C.
Same restriction as for category B plus dangerous goods that can lead to
a large explosion or extensive release of toxic substances.
Zeichen 261 - Verbot für kennzeichnungspflichtige Kraftfahrzeuge mit gefährlichen Gütern, StVO 1988.svg
Zusatzzeichen 1014-52 - Tunnelkategorie gemäß ADR-Übereinkommen (D), StVO 2007.svg
hazmat:D=no No access for vehicles carrying hazardous substances
which are not allowed to pass tunnels of category D.
Same restriction as for category C but also corresponds to dangerous
goods that can lead to large fire.
Zeichen 261 - Verbot für kennzeichnungspflichtige Kraftfahrzeuge mit gefährlichen Gütern, StVO 1988.svg
Zusatzzeichen 1014-53 - Tunnelkategorie gemäß ADR-Übereinkommen (E), StVO 2007.svg
hazmat:E=no No access for vehicles carrying hazardous substances
which are not allowed to pass tunnels of category E.
No passage for any dangerous goods, with the exception of UN2919, UN3291
and UN3373 (certain radioactive materials, clinical waste and materials)

Note:

For more details on type and amount of hazardous substances which are allowed to pass tunnel of a certain category, see Zweck des Tunnelbeschränkungscodes (TBC) (german).

Tunnel category A is specified but not required to be shown as traffic sign for road users as there are no restrictions for hazardous materials on this category. However, on tunnel entry portal you may find a plate like DE:1014-50 but showing letter A. This is for information only that this tunnel had been specified according to tunnel category A.

Guatemala

Netherlands

The Netherlands uses the European tunnel categories A - E. Traffic signs C22 Nederlands verkeersbord C22.svg and K14 Nederlands verkeersbord K14.svg relate to hazardous materials. These are translated to OSM-tags in the following way:

Croatia

Croatia uses the European tunnel categories A - E. However, until recently, these were not displayed as letters on signs at the road side. The exact restrictions of tunnels and other roadways can be found at https://narodne-novine.nn.hr/clanci/sluzbeni/2012_10_114_2487.html.

Previously, a sign reading, "Pozor! Obvezna pratnja kroz tunele!" was used, nearby a road sign pointing to a location where ADR-restricted vehicles may park to be inspected/prepare an escort.

Now, a significant distance prior to a restricted tunnel, a sign is used displaying the name of the tunnel, it's length, the distance away, any times of restriction, and the following sign with a single letter on a panel below designating the tunnel class.

United States

Main article: w:Dangerous goods#United States

Hazardous cargo restrictions have generally been tagged using hazmat=no. As of November 2020, very few class-specific hazardous cargo access restrictions have been tagged in the United States, so far mostly in California. Following the general guidance above, one would use keys under the hazmat:* namespace to indicate specific restricted classes:

To determine the correct class for each placard, consult the following guides from the U.S. Department of Transportation:

California signposts hazardous cargo restrictions using state-specific signs that do not explicitly include the placards:

Local transportation authorities may have their own detailed guides as well, such as this guide from the Port Authority of New York and New Jersey.
