Use highway=trunk for high performance roads that don't meet the requirement for highway=motorway. See Highway:International equivalence for guidance on the use of 'highway=trunk' in different countries.

How to map

Map dual carriageway.png

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.

Poland Znak D7.svgExpressway (Polish: Droga ekspresowa) – high-speed, limited-access highway with similar restrictions as in case of motorways (no bikes/horses/tractors allowed), but a bit lower technical parameters. In contrast to motorways it has lower speed limit (140 km/h for motorways vs. 120/100 km/h for dual/single carriageway expressways), it can be single carriageway (most are dual, however) and can have intersections with main roads (except for other expressways and motorways; but in practice probably there are no intersections on any Polish expressway). Reference numbers for expressways in Poland have 'S' prefix, for example S5 Tabliczka S5.svg. WikiProject Poland/Klasyfikacja dróg

Romania highway=trunk is used for any national road part of a European corridor or express ways (do not exist in Romania); along with the national road shield (white on red background) RO Roadsign 1.png there are also plates similar to this No sign-Eroad.png . The ref=* tag has the format DNn, DNnn or DNnnx (n=0-9, x=A-Z), while the tag int_ref=* has the format Enn or Ennn.
E.g.: DN6/E60, DN2/E85 .
