Generally roads with control of access are proclaimed in government documents, and have an official status as a controlled access road, sometimes this can include the term motorway, freeway or expressway among others in the road name. These kinds of roads usually have a special designation by the law, with a set of laws specifically applied on them. Generally some restrictions are placed on the kind of vehicles or traffic which can be on roads which should be classed as highway=motorway, such as no pedestrians, bicycles, livestock, horses and so on.
Selected limited access roads which can be classed as motorways include those that:
- Generally resemble a controlled access road and must be free from intersection controls (such as traffic-signals, rotaries and roundabouts, and stop signs or stop markings);
- Typically have at least two lanes in each traffic direction with some degree of separation;
- Have access roads only for servicing purposes, such as a limited number of driveways serving non-residential property, service roads to infrastructure, or rest-area roads or bays, which may be more typical in regional or rural settings
The tag highway=motorway_link should be used for the link roads, sliproads or ramps which lead to and from a motorway. Where one motorway terminates or begins on another the highway=motorway_link can be used to separate and identify the different motorway roads and the continuing route; that is, generally two diverging or converging highway=motorway ways should not meet or join in OpenStreetMap, but rather be separated by highway=motorway_link ways.
While the box on the right lists some implied tags, they have been changed several times, they are often country-specific and the community does not agree about the implications. It is suggested to include implied tags when mapping motorways regardless.
How to map
A motorway is normally represented by a series two parallel ways, one for each carriageway tagged with highway=motorway. These ways should all point direction of travel and be tagged with oneway=yes. In the less usual case of a motorway where traffic travels in both directions along the same carriageway use a single way and tag it with oneway=no. When drawing parallel ways, place the nodes for each direction next to each other, which results in a better representation on most maps. The following tags may be applicable:
|name=*||Name of the motorway.||Autostrada dei Fiori|
|ref=*||Highway code in the national highway network.||A 3|
|oneway=yes||See section #How to map|
|lanes=*||Number of lanes.||3|
|maxspeed=*||The maximum speed which is allowed (in km/h).||130|
|minspeed=*||Minimum driving speed on the motorway (in km/h).||50|
|destination=*||Name of town for the direction of the motorway. Normally the town written on the sign which belongs to the motorway-link.||Frankfurt|
|carriageway_ref=*||In the UK, the reference number for the carriageway, as displayed on Highway Agency signing||B|
|toll=yes||On paid motorways|
It is not desirable to split motorway into multiple highway=* lines at toll gates.
|Australia||Motorways, freeways, and freeway-like roads.
Divided roads with 2 or 3 lanes in each direction, limited access via interchanges, no traffic lights. Generally 100 or 110 km/h speed limit. For example: Hume Freeway.

|Venezuela||Se califica como autopista a una vía rápida que cumpla con las características de:
1. Tener un separador físico en el medio, ya sea un muro de concreto o una gran extensión de tierra, que divida las dos calzadas de flujo.
2. La misma debe ser accedida exclusivamente a través de un distribuidor vial y no contener cruces ni semáforos a lo largo de su travesía.
Si la vía rápida no cumple con ambas características, se le debe clasificar como una Principal (trunk)
