Status: Approved

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.

For roads that do not meet the above requirements consider using highway=trunk. See Highway:International equivalence for guidance on the use of motorway in different countries.

Use highway=motorway_link for shorter link roads (sliproads/ramps) leading to and from a motorway.

Implied values

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

highway=motorway, lanes=4, oneway=yes, int_ref=E 451, ref=A 5, destination:Darmstadt

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:


Tagging scheme for highway=motorway
Tag Description Example
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)).

Use highway=motorway_junction at each point along a motorway with numbered exits to identify the exit number.
