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 this road
- name=Name of the road
- ref=reference name e.g. "B 6", see your countries road identification system
- lanes=Number to indicate how many lanes exist on the trunk road.
- motorroad=* indicates if this road has the Motorcars Only traffic rule
- 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 trunk_link see highway=motorway_link)
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 + layer=1 - If the trunk road goes over a street or waterway.
- tunnel=yes + layer=-1 - If the trunk road goes below a street or waterway.
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.
|Australia|| National highways; state strategic road network.
Connecting major population centres. For example Bruce Highway, Pacific Highway.
|Australian Roads Tagging|
|Austria||Autostraße Note the small difference to the Motorcars Only traffic sign in Germany.||WikiProject Austria/Schnellstraßen|
|Brazil||Rodovias nacionais (national highways, such as BR-262), vias expressas urbanas (urban expressways), 70-80 km/h|
|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).|

Par défaut : lanes="2", maxspeed="110" (sauf périph. Paris: 80)
+ ref="Nxx" ou "Dxx"
+ lanes="x" (si voies <> 2)
|Germany||For Motorway Like Roads (Autobahnähnliche Straße collq. Schnellstraße) without crossings. The carriageways are separated physically or by road markings. This sign indicates a trunk road. Neither bound to an administrative class like nor to the traffic rule Kraftfahrstraße (motorroad=yes) indicated by this sign . Note the very similar Austrian sign which indeed indicates a road class.||DE:Tag:highway=trunk|

|Ireland (Republic)||National Primary Routes, regardless of build quality. Currently numbered N1-N33. Signed in white lettering on a green background.|
|Israel||National Primary Routes, regardless of build quality. They are numbered with one or two digits. Red numbers on a white background surrounded by green border.||WikiProject Israel He:Map Features|
|Italy||Strade a scorrimento veloci regolate da rampe di entrata/uscita e prive di incroci a raso e di rotatorie che si pongono a metà strada tra Autostrade e le Statali. 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.|
|Korea|| Divided highway without ramps.|
Higher speeds. Few stop lights or stop signs.
|Morocco||Rocade, expressway.2x2 Divided highway, every intersections with roundabout.speedlimit 80 or 100 km/h|
|New Zealand|| 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.
|Norway||Nation infrastructure road (Riksvei) that are not "Motorvei" , green signs, include E-roads class A and B||No:Map Features#Road classes|
|Philippines||Primary national roads connecting major cities and provinces.
Examples are the Pan-Philippine Highway/AH26 (not including toll expressway segments, like segments on NLEX and SLEX) that are tagged highway=motorway) , Daang Maharlika, MacArthur Highway, EDSA (includes portions not marked as part of Pan-Philippine Highway/AH26), Aguinaldo Highway, Governor's Drive, Jose P. Laurel Highway (mostly designated as Manila - Batangas Road, but short segment at Santo Tomas is designated as Santo Tomas Bypass Road) , Andaya Highway, Strong Republic Nautical Highway, etc.
|Poland||Expressway (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 .||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) there are also plates similar to this . 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 .
|Slovak Republic||Cesta pre motorové vozidlá: and other high-speed 4-lane roads exclusive for motor vehicles|
|Switzerland||Autostrasse / autoroute de 2eme classe (semi-autoroute)|
|Tanzania||Refers to a (paved) 'Trunk Road', as classified by Tanroads. Main roads that connect major cities in the country: e.g. T1 from Dar es Salaam - Zambia border.|
|UK||primary A road (green signs)|
|US||Surface expressway: A relatively high-speed divided road (at least 40 MPH with a barrier or median separating each direction of traffic), with a limited amount of intersections and driveways; or a major intercity highway. This includes many U.S. Highways (that do not parallel an Interstate) and some state highways. Wikipedia reference|
|Vietnam||Trunk (Xa lộ) in Vietnam usually have more than 3 lane with lane classification signs|
