希腊 2nd-tier National Roads WikiProject Greece § Road Network
意大利 Strada Statale (SS) or Strada Regionale (SR) The "SSs" are mostly primary. You should also indicate the name of the highway, if it has one, example:

"SRs" can be tagged as primary as well, if they have a relevant role in linking two major cities.

In general the highway-tag is not representing the administrative class but the importance of the connection.

By default this kind of highway is rendered:

  • with a label carrying the "ref" field at lower zoom levels;
  • with the name of the highway at higher zoom levels.
新西兰 State Highways and strategic local roads All State Highways which do not meet the criteria for highway=trunk. Generally two lanes undivided with limited passing lanes and occasionally one-lane bridges.

Strategic local roads are generally the most important roads that are not State Highways. They may be multi-lane divided, or connect major airports, seaports or isolated areas of a city. Examples include South Eastern Highway and Manuaku Road in Auckland, Wairere Drive in Hamilton, and the "Four Avenues" in Christchurch.

葡萄牙 National Roads (with ref=EN *) and important urban avenues with two lanes in each direction. National Roads which are not officially declassified. If it's a declassified EN, it may remain a primary if it is of first order (ex: EN 109). In urban centres, important avenues and arteries with two lanes on each way and a physical separator are also primary.
瑞士 Hauptstrasse There are two kind of "Hauptstrassen" in Switzerland:
Example of a signpost for a numbered "Hauptstrasse"
Use multiple numbers separated by semikolon (;) if a segment is used by more than one numbered "Hauptstrasse". Example: ref=6;12
Example of a signpost for a normal primary highway

In contrast to other routes, for example cycling or hiking routes, we do not use relations to model numbered "Hauptstrassen" in Switzerland, use ref=number as described above.

美国 Primary highway or arterial road. U.S. Highways are mostly primary.

Some State Roads are also primary, the criterion being either connecting large towns/cities, or being a major road in an urban area.

By default this kind of highway is rendered:

  • with a label carrying the "ref" field at lower zoom levels;
  • with the name of the highway at higher zoom levels.
巴西 Via arterial urbana (urban arterial way), estrada estadual (state road), >50-60 km/h
菲律宾 Other national roads that is used as a city/ arterial road rather than an intercity road, or a connector, if it only feeds secondary/tertiary roads. Provincial roads linking municipalities with a major highway. Roads linking a city/municipal center (poblacion) with a major national highway. National roads usually fall as trunk highways, as they carry most intercity traffic, but some national roads should be tagged primary if they are usually roads serving local traffic in a city/rural area or a connector between two trunk highways, when it feeds roads tagged as secondary or tertiary.
荷兰 Mainly "N-ways" below 400, often called a "provincial way" See NL:The_Netherlands_roads_tagging
委内瑞拉 It is the regional highways network that connect minor cities and important towns.

In cities they are usually the most important avenues, directly connecting large remote areas of the city, or distributing the national traffic through them.

Usually used for roads that run parallel to motorways which were the main road before its construction, called "carreteras viejas", depending on the importance of it for that region.
