Future definition?

The key agricultural=* can describe the legal effects of the traffic sign B06cr.jpg.
Additionally the key may be used to allow slow vehicles on motorroads. A better definition is needed because currently the key is prone to wrong tagging.

On ~57.000 ways the key agricultural=* is currently tagged. The number of ~26.500 agricultural=yes tags exceeds the number of ~25.000 agricultural=no tags. So this key is mainly used against its definition as restrictive key.

The reasons are:


Several legal restrictions are bound by lawmakers to this traffic sign. At least three different vehicle groups are addressed with this sign in Europe:
* Vehicles bound to agricultural purpose (seldom)
* Technical kind of vehicle: tractors and self-propelled working machinery (most countries)
* Maximum technical or legal speed of the vehicle (modern)

agricultural can also be a value for access restriction tags. To ban motorized traffic these signs are placed at nearly every crossing between a road and a track in Germany. This traffic sign combination needs the tag (motor_vehicle=agricultural) only. Currently editors like JOSM do not clearly present this simple solution and inappropriate tagging occurs. The numbers above show the amount (more bad than good).


Nederlands verkeersbord F11.svg
In 2015 The Netherlands introduced a new traffic sign with the same icon. This will complicate the tagging situation.

In retrospective the key tractor=* would have been fit better. It is tagged some hundred times currently. A complete replacement is expected to be difficult.


The Vienna Convention has two definitions (consolidated version 2006, chapter I article 1):

(o) “Power-driven vehicle” means any self-propelled road vehicle, other than a moped in the territories of Contracting Parties which do not treat mopeds as motorcycles, and other than a rail-borne vehicle;
(p) “Motor vehicle” means any power-driven vehicle which is normally used for carrying persons or goods by road or for drawing, on the road, vehicles used for the carriage of persons or goods. […] It does not cover vehicles, such as agricultural tractors, which are only incidentally used for carrying persons or goods by road or for drawing, on the road, vehicles used for the carriage of persons or goods;

In French the terms véhicule à moteur and automobile are used under the letters (m) and (n) in the original treaty from 1968. If both terms translate into a single one like Kraftfahrzeuge, then the broader definition is meant or otherwise an addendum is used.

So a power-driven vehicle has the subclasses motor vehicle (mainly for road use) and other vehicle (like excavators or truck-mounted cranes, for which each country can decide the technical requirements, see Art. 3 Nr. 2 (b))


Effective since 1. January 2017 the European Union allows tractors and other self-propelled machinery with a maximum speed over 60 km/h. So you can expect agricultural tractors on motorways.

In 5 countries the maximum speed of a vehicle is bound to the tractor traffic sign:

  1. Germany: The sign 257-58 was newly introduced in January 2017 and means "Verbot für Kraftfahrzeuge und Züge, die nicht schneller als 25 km-h fahren können oder dürfen." (= Forbidden for motor vehicles and vehicle combinations, which cannot or may not drive faster than 25 km/h).
  2. Greece: The sign P 18 means [1]"No access for motor vehicles that cannot exceed 25 km/h (tractors)".
  3. The Netherlands: The sign C8 means [2]"Gesloten voor motorvoertuigen die niet sneller kunnen of mogen rijden dan 25 km/h" (= Closed for motor vehicles that cannot or may not drive faster than 25 km/h).
  4. Norway: The sign 306.3. means [3]"Forbudt for traktor og for motorredskap konstruert for fart mindre enn 40 km/t" (= Prohibited for tractor and for engine gear designed for speed less than 40 km/h)
  5. Poland: The sing B-6 means [4] "'zakaz wjazdu ciągników rolniczych' oznacza zakaz ruchu ciągników rolniczych i pojazdów wolnobieżnych." (= 'prohibition of entry of agricultural tractors' means a ban on the movement of agricultural tractors and slow-moving vehicles.) So this one rule draws two limits: All agricultural tractors and all self-propelled vehicles up to 25 km/h.

In 13 countries the kind of a vehicle is bound to the tractor traffic sign:

  1. Croatia: The sign B13 means [5]"'zabrana prometa za traktore' označuje cestu ili dio ceste na kojoj je zabranjen promet traktorima." (= 'Tractor traffic prohibition') means the road or part of a road where tractors are prohibited). Formerly this sign had the number 213.
  2. Czech Republic: The sign B 6 means [6]"Zákaz vjezdu traktoru" (= no tractor access forbids tractors) Also single-axle tractors and self-propelled work machines are forbidden.
  3. Denmark: The sign C 24,1 means "Traktor og motorredsskab forbudt" (= Tractors and working machines forbidden.) Even food selling trailers are counted as motorredskab. The speed limit for working machines is 30 km/h.
  4. Estonia: The sign EE 316 means [7]"'Traktori sõidu keeld.' Sõita ei tohi traktori ega liikurmasinaga" (= 'Tractor driving prohibited.' Do not drive with a tractor or machine.)
  5. Finland: The sign 315 means [8]"Traktorilla ajo kielletty. Kielto koskee myös ajamista moottorityökoneella." (= Driving with a tractor is prohibited. The ban also applies to driving on a power-driven machine.)
  6. Hungary: The sign C-016 means[9]"'Mezõgazdasági vontatóval behajtani tilos' a tábla azt jelzi, hogy az útra mezõgazdasági vontatóval és lassú jármûvel behajtani tilos" (= 'It is forbidden to drive with an agricultural tractor' The sign indicates that it is forbidden to enter the road with a tractor and a slow vehicle.).
  7. Iceland: The sign B03.41 means [10]"Akstur dráttarvéla, torfærutækja á hjólum og vinnuvéla bannaður." (= Driving the tractor, off-road vehicles on wheels and working machinery forbidden.)
  8. Luxembourg: The sign C, 3k means [11]"Le signal C,3k indique que l’accès est interdit aux conducteurs de tracteurs et de machines automotrices." (= The signal C, 3k indicates that access is prohibited to drivers of tractors and self-propelled machines.)
  9. Romania: The sign means [12]"Accesul interzis tractoarelor și mașinilor autopropulsate pentru lucrări" (= Prohibited access to tractors and self-propelled machinery for works).
  10. Russia: The sign 3.6 means [13]"Запрещается движение тракторов и самоходных машин любого типа." (= The movement of tractors and self-propelled machines of any type is prohibited.)
  11. Slovakia: The sign B9 means [14]"Zakazuje vjazd traktorom a všetkým zvláštnym motorovým vozidlám, ako sú napr." (= It prohibits the entry of a tractor and any special motor vehicle such as ...).
  12. Sweden: The sign C8 bans [15]tractors and self-propelled working machines.
  13. Ukraine: The sign 3.5 means [16]"Запрещается движение тракторов, самоходных машин и механизмов." (= The movement of tractors, self-propelled machines and mechanisms is prohibited.)

In 4 countries the property agricultural vehicle or another currently unclear definition is bound to the tractor traffic sign:

  1. France: The sign B 9 d means [17]"Accès interdit aux véhicules agricoles à moteur." (= Access prohibited to agricultural motor vehicles.) It was introduced in 1964. An adaption of the new EU laws into the french traffic laws is expected [18].
  2. Italy: The sign II 62 means [19]"Transito vietato alle macchine agricole" (= Transit prohibited to agricultural machinery) Other vehicles are not affected.
  3. Portugal: The sign C3h means [20]"trânsito proibido a veículos agrícolas" (= Transit prohibited to agricultural vehicles)
  4. Spain: The sign R-111 means [21]"entrada prohibida a vehículos agrícolas de motor" (= prohibited entry to agricultural motor vehicles)

Some countries do not have a restrictive traffic sign with a tractor icon:

  • Austria: The additional sign i [22]"Eine solche Zusatztafel unter dem Zeichen „Überholen verboten“ zeigt an, dass Zugmaschinen, Motorkarren, selbstfahrende Arbeitsmaschinen und vierrädrige Leichtkraftfahrzeuge überholt werden dürfen." (= Such an additional plate under the sign "Overtaking prohibited" indicates that tractors, motor carts, self-propelled working machines and quadricycles may be overhauled.) targets a variety of vehicles.
  • Belgium: Has not even an additional sign.
  • Ireland: Traffic laws are a complete mess[23].
  • Switzerland: The additional sign 5.36 "Traktoren" (=tractors) isn't explained. But the Swiss traffic rules[24] differentiate between commercial tractors (60 km/h maxspeed) and agricultural tractors (30 km/h maxspeed when towing unlicensed trailers). So we can assume that the sign means all tractors.
  • United Kingdom: No sign.


Bound to kind of vehicle

For example, road signs pictured in File:Shimotsui electric railway Amaki Station mark.JPG means "bicycles and pedestrians only" and "except special small motor vehicle". Expressways in japan has limit of minimum speed of 50 km/h, thus special small motor vehicles have no access for expressways.

Collected above are only regulatory signs and rules for slow vehicles themselves. Left out are warning signs about slow or farming vehicles.


Response to above overview by @Hb

Hi @Hb:, many thanks for this extensive overview, there is a lot to learn here. It might be a good idea to sign it using the methods mentioned here?

Small update on the passage below:

:# The Netherlands: The sign C8 means [58]"Gesloten voor motorvoertuigen die niet sneller kunnen of mogen rijden dan 25 km/h" (= Closed for motor vehicles that cannot or may not drive faster than 25 km/h).

This text was indeed correct at the time of the url in your overview (2018-07-01), but the definition has changed in the meantime and is now:

C8: Gesloten voor landbouw- en bosbouwtrekkers, motorrijtuigen met beperkte snelheid en mobiele machines

Background on this change can be read here
