Tools for this tag

Use highway=trunk for high-performance or high-importance roads that don't meet the requirements for motorway, but are not classified as primary either (subject to country-specific exceptions listed below). In different countries, either performance or importance is used as the defining criterion for trunk – see #International equivalence and the international highway classification equivalence for guidance on road classification in different countries.

How to map

To map a simple trunk road you can just draw a way 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 per 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 this road
  • name=Name of the road
  • ref=reference code e.g. "B 6", see your countries road identification system
  • int_ref=* International reference number E.g. E 12
  • lanes=Number to indicate how many lanes exist on the trunk road.
  • motorroad=* indicates if this road has the motorcars only traffic rule
  • expressway=* indicates if this road is an expressway: a dual-carriageway (divided) highway with high-speed design features, plus limited access to adjacent properties or grade-separated interchanges.
  • toll:N3=yes - Tolls for trucks with a maximum permissible weight> 12 t
  • destination=* Indicates where the road 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 a trunk link see trunk_link)

Special situations

When a highway section runs over a bridge or through a tunnel, split the way from the rest of the road and tag it with one of:

  • bridge=yes + layer=* - if it goes over a street or waterway.
  • tunnel=yes + layer=* - if it goes below a street or waterway.

Determine an adequate layer value: use layer=1 for a bridge over a single ground-level feature, layer=-1 for a tunnel under a single ground-level feature, or a different value to represent the vertical stacking of multiple map features.

Strategic State Highways
State highways linking major urban areas (population 30,000+), major ports, major airports, international tourist destinations, and/or remote regions. Generally two lanes, undivided with regular passing lanes. All state highways not meeting the criteria should be tagged primary.

Pakistan National Highways, such as the G.T Road which runs throughout Pakistan. All Grand Truck roads are indicated with a blue highway ref sign.
  • Use ref=* to add the road number such as ref=N-5.
  • Trunk Roads will usually be one-way with at a minimum of 2 lanes
  • Service roads should be separate to highways and trunk roads.

Poland Some (e.g. single-carriageway) droga ekspresowa roads.

Note that most (~95%) of droga ekspresowa roads in Poland are good enough to be tagged as motorway – high-speed, limited-access highway with similar restrictions as in case of motorways (no bikes/horses/tractors allowed), but a bit lower technical parameters (e.g. lower speed limit 140 km/h for autostrada vs. 120/100 km/h for dual/single carriageway droga ekspresowa). trunk is applied to those small portion of droga ekspresowa roads that do not fulfil motorway requirements, since some of them still can be single carriageway. They are also allowed to have at-grade intersections in exceptional cases, but since 2020 no such intersections exist.[1][2][3] Reference numbers for expressways in Poland have 'S' prefix, for example S5 .

United Kingdom Primary A road (green signs)
United States highway|trunk}} should be applied in the following cases:
  • In areas of high population density, to expressways that meet most, but not all, of the requirements for motorway, and provide connectivity between motorways and other trunk roads. These roads should also be tagged expressway=yes.
  • In areas of medium to low population density, to the most important non-motorway roads that provide principal, long-haul connections between population centers of regional importance.

Historically, trunk in the US has been defined based on physical construction, but the 2021 US highway classification project has moved to a definition based on network importance.

Venezuela National roads network that cross the entire country connecting the most important cities. Venezuela roads tagging (es), National roads of Venezuela (es)
Vietnam Trunk (Xa lộ) in Vietnam usually have more than 3 lane with lane classification signs.

Examples

Note that trunk is classified by its importance in road network, not by its quality (though in given area these two tend to correlate strongly).

In one place multilane double carriageway can be primary or lower - and in another part of the world, with poor road quality trunk may be single lane road surfaced with gravel.
