Status: in use

The source:maxspeed=* tag records the source of a road's maximum Speed limit as provided in the maxspeed=* tag to assist with Verifiability and maintenance. This may be a sign giving a numeric maximum speed, or a 'zone' from which the appropriate numeric speed limit can be determined by knowledge of local traffic laws.

How to tag

See also: Speed limits
  • sign (where the speed limit is defined by a numeric sign.)
  • markings (where the speed limit is defined by painted road markings.)
  • <country_code>:<context> (where the speed limit is defined by a particular context, for example urban/rural/motorway/etc., and no maxspeed is signposted)

Do not use <country_code>:<context> where there are signs that are prescribing the same maxspeed as the default.

Examples

An urban road in Italy would be tagged:

Where the speed limit is indicated by special speed limits signposted at the zone boundaries they can be tagged as follows:

other (less recommended) variations

  • maxspeed=30 and source:maxspeed=DE:zone - Proposed by a discussion on a mailing list citation needed (used 4k times in May 2014), usage stagnating according to taginfo history (5779 as of 3/2017)
  • maxspeed=30 and source:maxspeed=zone - Proposed in the discussion of this page (analogously to other not country and speed-specific values like sign and markings) (usage stagnating, 1,8k as of 3/2017)

Country-specific exceptions

In some areas, default maxspeeds are not uniform in the whole country, in these cases simply use more refined codes referring to the area.

Belgium

There are two relevant regions (different default rural maxspeed), Flanders and Wallonia, with these ISO codes: source:maxspeed=BE-WAL:... and source:maxspeed=BE-VLG:... As the Brussels-Capital Region has no rural road, there is also no need for a corresponding tag.

United Kingdom

The U.K. community uses the key maxspeed:type=* and, in general, reserves this tag to describe how the maxspeed was determined with values comparable to the main source=*. The issue being that if source:maxspeed is used for the type of speed limit there is no tag to describe how the data were acquired. The UK has a specific sign meaning "speed restriction lifted, national speed limit applies" where the actual speed will depend on the road type (single or dual carriageway). Some U.K. use source:maxspeed=* to tag the source of the information as for other tags of the form source:*. After prolonged discussion of this point on talk-gb resulted in agreement to use source:maxspeed for the data source (survey, Open Data, etc) and maxspeed:type=* for the information described on this page. This usage is more consistent with the general pattern of tagging. It also resolved a conflict about how unsigned national speed limits should be tagged.

Note that this section applies to the United Kingdom as a whole (not Great Britain alone).

Context Specific Values (Default Limits)

As described above the source:maxspeed=* may use context specific values, such as where a road is unsigned and a "default" maxspeed value in-force by legislation / law applies.

source:maxspeed=* should not be used alone, and should be used with maxspeed=*, as the source does not imply a specific maxspeed value. Excluding certain situations in Romania and Russia a numerical value is preferred (refer to maxspeed=*).

  • Default (unsigned) speed limit in built-up areas is 50km/h in all states and mainland territories excluding the Northern Territory, where it is 60km/h.
  • Default (unsigned) speed limit outside of urban built-up areas (such as suburbs or towns) is 100km/h in all states and mainland territories excluding the Northern Territory and Western Australia, where it is 110km/h.
  • Signed speed limits exceeding the defaults may apply, and this applies only to the states and mainland territories.

  • Buses and trucks subject to lower speed limits (60 km/h in motorways[3], 50 km/h in rural areas)
  • Cars and motorcycles in urban areas subject to higher speed limits only in designated through streets or boulevards without blind corners (40 km/h).
  • Places classified as "crowded streets" by local government units, areas close to intersections at blind corners and passing school zones have a speed limit of 20 km/h regardless of motor vehicle type.
  • Local government units may assign lower speed limits[4]

  1. This value seems unnecessary, since the speed limit of 50 km/h in urban areas is always signed at the entrance of the settlement by road sign 2.30.1.
  2. 130 km/h is the recommended maximum speed on motorways, as indicated by a square blue sign (round blue sign = minimum speed). Many sections of the German motorway network are now covered by speed limits, usually ranging from 80 to 130 km/h (140 km/h as speed limit is being tested in Lower Saxony -some politicians are against it, because 140 km/h is over the recommended maximum speed, depending on local conditions (i.e., frequent traffic, terrain, etc.). It is usual for drivers involved in crashes who were exceeding the 'recommended' speed limit to be held to be at least partly at fault, regardless of the circumstances of the crash, and insurance companies have the right to withhold payment. Already more than 50% Autobahns now have a (partially variable) speed limit. Vehicles also must be able to go faster than 60 km/h. Roughly 30% of german Autobahn have permanent limits. An additional 17% have at least partial limits depending on time, weather or traffic. Study on the speed limit on german Autobahn. Archived 25 May 2013 at the Wayback Machine.
