| +/- highway=motorway
High capacity highways designed to safely carry fast motor traffic.
Use highway=motorway to identify the highest-performance roads within a territory, typically controlled-access highways with a minimum of two lanes in each direction separated by a barrier (referred to as a freeway' in American and Australian English and as an Autobahn in German). Non-motorised traffic is banned from using these roads in most territories, with some exceptions, for example rural motorways in western U.S.
How to map
A motorway it 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 i 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=*||Reference name.||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 wich 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.
