Important roads that aren’t motorways. Often suitable for long journeys or relatively high speeds. In many countries this tag has a specific meaning, see #International equivalence below.

Generally always paved, unless tagged otherwise.

How to map

To map a simple trunk road you can just draw a line for it. Select all ways which belong to the trunk road and tag them with highway=trunk. As always, use oneway=yes when it is not possible to drive in both directions on the trunk road, and make sure the way points in the same direction as the oneway goes.

In the case of a dual carriageway you should draw one way for each direction and tag each direction separately. Position the nodes in alignment (as shown), this gives a better result when the map will be rendered and indicates directly that both ways belong together.

To attach more information for the trunk road you should add further keys.

• maxspeed=Number indicates the maximum speed which is allowed
• minspeed=Number indicates the minimum speed which need to be reached to use the trunk road
• name=Name of the road
• ref=reference name for a german example: "B 6" (Please look for your country, how this is written correctly)
• lanes=Number to indicate how many lanes exist on the trunk road.
• motorroad=yes (don't use trunk-only for primary motorroads!)
• destination=* Indicates where the trunk goes to. Consider the direction of the way and use the name of the city written on the sign which belongs to the trunk_link: for example "London" (for trunk_link see highway=motorway_link)

Special situations

In the case you do not have a normal trunk road you should take a look on these sites:

• highway=trunk_link - The link roads (sliproads / ramps) leading to and from a trunk road.
• bridge=yes - If the trunk road goes over a street or waterway.
• tunnel=yes - If the trunk road goes below a street or waterway.

International equivalence

Below is a comparison of how some of the tags are assigned in different countries. Users should consult the guide for the particular country for more details and additional tags. See Category:Projects for country specific projects and Tagging for list of country specific tagging guides.

Brazil	National highways - For example: BR-262.
Bulgaria	Скоростен път с поне две ленти във всяка посока. Ограничението на скоростта не трябва да е по-малко от стандартното (50 км/ч за населени места, 90 км/ч извън тях).

Germany	Autobahnähnliche Straßen (Wikipedia), wie definiert in den Richtlinien für die wegweisende Beschilderung außerhalb von Autobahnen, kurz RWB. Die Straßen sind an dieser schwarz-gelben bzw schwarz-weißen Beschilderung erkennbar, wie vom Bundesministerium für Verkehr, Bau- und Wohnungswesen veröffentlicht. (Videofahrt) Roads similar to motorways as defined in German Signpost Regulations outlying of Bundesautobahns with these black-yellow or black-white signposts as published by German Federal Ministry of Traffic, Building and Housing.

Italy	Strade che si pongono a metà strada tra Autostrade/Tangenziali e le Statali. Può anche essere classificato così il tratto di svincolo di un'autostrada-tangenziale che porta al centro città. Per segnalare l'esistenza di restrizioni di accesso identiche a quelle in vigore per le autostrade, usare motorroad=yes. Solitamente le Strade extraurbane principali sono di questo tipo.
Japan	国道/National Highways
