|highway = motorway|
|High capacity highways designed to safely carry fast motor traffic.|
|Used on these elements|
|Tools for this tag|
The tag highway=motorway is used to identify the highest-performance roads within a territory. Typically, these controlled-access highways have a minimum of two lanes in each direction that are separated by a barrier. Motorways are commonly referred to as a freeway in American and Australian English. These kinds of roads usually have a special designation by the law, with a set of laws specifically applied on them. Non-motorised traffic is banned from using these roads in most territories, with some exceptions, for example rural motorways in western U.S.
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. Please tag them anyways to clear out any doubt.
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 speed which a vehicle must be capable of to use 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|
Consider adding the all of these ways to a relation of type (what type of relation? PeterIto 02:47, 20 January 2013 (UTC)).
|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.
