Restrictions générales au sein de l'Union Européenne

Une régulation spécifique s'applique aux tunnels (et route), elle est bassée sur un traité onusien signés par plus de 50 pays (pas tous de l'Union Européenne). Ce traité ADR définit 5 catégories (A, B, C, D, E).

• EU minimum safety requirements for tunnels https://ec.europa.eu/transport/road_safety/topics/infrastructure/tunnels_en

Restrictions spécifiques

Finlande

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

L'usage le plus fréquent est hazmat=no.

Le gouvernement français publie une liste non exhaustive des tunnels restreignants le transport des matières dangereuses: Tunnels de + de 300 m - régime TMD - liste non exhaustive (Centre Étude des TUnel alias CETU) La majorité d'entre-eux sont soit du groupe A soit du groupe E.

Allemagne

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=*.

Additionally Germany uses the European tunnel categories A - E. Traffic sign DE:261 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:

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.

Guatémala

Pays-Bas

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

États-Unis d'Amérique

Article principal : 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:

• Nine Classes of Hazardous Materials (Yellow Visor Card)
• Hazardous Materials Markings, Labeling and Placarding Guide (DOT Chart 15)
• How to Comply with Federal Hazardous Materials Regulations

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

• Hazardous waste
• Hazardous material
• Specific classes of hazardous material

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.
