|Tools for this tag|
Access values are used to describe the legal access for highways and other transportation networks (railways, waterways) as well as other facilities including building entrances, buildings themselves, amenities and leisure entities.
The values can be used with the access tag or with tags associated with particular forms of transport. For example access=delivery on a service road tagged with highway=service would imply that all transport modes can use the entrance for delivery only. A building entrance available for pedestrian customers only would be tagged entrance=yes and foot=customers. In addition to transport mode restriction, there may be restrictions relating to height, weight, restrictions may vary by time and day and restrictions may be directional.
Because there are so many access tags for transport modes, you may also use a grouping prefix for clarity. Thus bicycle=yes is sometimes found as access:bicycle=yes, though this is less widely supported by data consumers and adds no additional meaning.

Access tag values
|yes||The public has an official, legally-enshrined right of access; i.e., it's a right of way.|
|no||No access for the general public. Consider using additional access (like foot=yes or bicycle=permissive, etc.) to indicate who can use the element. If only specific transport modes are forbidden, prefer more specific restrictions like vehicle=no or motor_vehicle=no over the general key access.|
|private||Only with permission of the owner on an individual basis.|
|permissive||Open to general traffic until such time as the owner revokes the permission which they are legally allowed to do at any time in the future.|
|destination||Only when travelling to this element/area; i.e., local traffic only. NOTE: This restriction often only applies to certain modes of transportation (e.g., only to vehicles). Take care to use the right transport mode restriction; e.g., vehicle=destination when only vehicle traffic is restricted.
English: "except for access" (UK) / "no thru traffic" / "local traffic only" (USA), Dutch: "bestemmingsverkeer/uitgezonderd plaatselijk verkeer (Flanders/Belgium)", German: "Anlieger frei"/"ausgenommen Anrainerverkehr" (Austria), French "Interdit sauf riverains/excepté circulation locale (Wallonie/Belgium)".
|delivery||Only when delivering to the element.|
|customers||Only for customers of the element. If access is not open to any person willing to pay, consider using private instead. Membership clubs are generally tagged as private.|
|designated||A preferred or designated route for the class of traffic specified by the tag key, such as foot=designated. Using this value with the plain access key, access=designated, has no meaning, and should not be used. (see #Transport mode restrictions)|
|use_sidepath||Can only be used in countries with compulsory cycleways and gives access information on parallel roads. See bicycle=use_sidepath.|
|dismount||Permitted for some vehicle (or animal) only if you dismount. Mostly used for bicycle: Use bicycle=dismount when people are not permitted to cycle (e.g., through a graveyard) but are allowed to dismount and bring the bike. See Bicycle#Bicycle Restrictions.|
|agricultural||Only for agricultural traffic.|
|forestry||Only for forestry traffic.|
|discouraged||A legal right of way exists (see yes) but usage is officially discouraged (e.g., HGVs on narrow but passable lanes). Only if marked by a traffic sign (subjective otherwise).|
|unknown||The access conditions are unknown or unclear.|
Access time and other conditional restrictions
Restrictions may be limited to a particular time or day. Or they may limit the access for vehicles over a certain weight. Such conditions can be tagged as shown in these tagging examples:
- Only destination access is permitted during 8am and 5pm on Mondays to Fridays:
access:conditional=destination @ (Mo-Fr 08:00-17:00)
- Motor vehicles heavier than 5 tonnes may only access this street for the purpose of delivering goods:
motor_vehicle:conditional=delivery @ (weight>5)
Please note that the above tagging style can be used to replace the following time dependent restrictions. It has been suggested that they be deprecated and should therefore no longer be used. date_on=*, date_off=*, day_on=*, day_off=*, hour_on=*, hour_off=*. Also note, that using of conditional tag assumes overt indication of value, which mostly suites as a default value. For example, if access is open on one part of day (on this part of day access=permissive) and is closed on other part of day (on this part of day access=private), we have a situation, when we should mark the object with a tag access=permissive or access=private. There is no concrete, precise and universal algorithm to define, if we should use permissive or private in concrete situation, but we can definitely say, that in such case we can't use access=yes (or not use tag access at all), because access=yes (or absence of tag access) means round-the-clock open access for general public.
- For a full description and more examples, please see the conditional restrictions page.
Size and statutory restrictions
A number of statutory restrictions based on height, width, weight, etc. can also be defined. A assumed units are the appropriate SI unit and should be specified without any suffix. For lengths use metres, for weights use metric tonnes and for times use hours. Decimal numbers should include a decimal point. Exceptions include speeds which should be in mph in places where speed limits are defined in these units and times which can include a suffix of 'days' if appropriate.
- maxheight=* height restriction.
- maxheight:physical=* physical height restriction.
- maxwidth=* (also note width=* for the physical width of the entire road.)
- maxspeed=* (km/h by default, mph where specified)
- mindistance=* minimum trailing distance, often as mindistance:hgv=* on old bridges or in tunnels
- maxstay=* (maximum parking time)
Ways may have different access restrictions for each direction. The most simple case is a way designated as a oneway road:
- Driving is only allowed in the direction of the way.
- Driving is only allowed against the direction of the way.
- Default. Access is allowed in both directions (this key/value combination does not normally need to be added to ways, unless another tag such as highway=motorway implies oneway=yes).
For more complex direction dependent restrictions, the postfixes
:forward can be used on the keys, for example:
- When a road has a oneway cycleway next to it that must be used, and a cyclelane in the other direction.
- When cyclists are allowed to travel in both directions on a oneway street (but no lane is present).
Also in use when cyclists are allowed to travel in the opposite direction:
- Only if a separate lane exists.
- Only if a separate track exists.
- Consistent with tags based on conditions. Note: This was previously tagged as "bicycle:oneway=no", but this is deprecated.
The oneway tag can be translated (for routing purposes) to this generic system as follows (oneway restrictions presumably do not apply to pedestrians):
Lane dependent restrictions
- Main article: Lanes
Access restrictions may differ between lanes.
- Heavy good vehicles are not allowed on the leftmost lane of a road with three lanes.
- Buses are not allowed on the leftmost lane of a road with three lanes in forward direction. The rightmost lane is a designated bus lane.
Transport mode restrictions
Use the access=* key to describe a general access restriction that applies to all transport modes.
In theory, adding access=yes to highway=footway could be read as changing default restrictions (which usually are foot=yes and vehicle=no for highway=footway) to yes, highway=footway + access=yes means "road, which is open for all pedestrians and vehicles".
In practice, this combination is often used by mappers to modify (rather than enlarge) default values: for example, access=permissive with highway=steps is very unlikely to be traversable by a truck, whatever the tags may say.
To avoid ambiguity, you may therefore want to avoid general tags access=yes and access=permissive, and use more specific transport modes where appropriate. For example, to distinguish a footway with open access from one with private access, use tags like foot=yes and foot=private instead of access=yes and access=private.
Where different restrictions apply to different modes of transport then mode specific tags can be used. These modal tags each have a place in a hierarchy in which keys become narrower in scope as they branch out from the root.
- access=yes, foot=no means that all transport modes except pedestrians can use the element
- access=forestry, foot=permissive implies that forestry vehicles can use the route legally and that pedestrians can use it by currently but that permission may later be withdrawn.
- See examples section for more examples.
This hierarchy is different in each country. So it's possible that your country has vehicle classes which aren't in this list, doesn't have some which are, and some vehicle classes may even have a different definition from the one listed below:
- access=* (category: any land-based transportation mode)
- Moving without a vehicle
- horse=* (horse riders)
- vehicle=* (category: any vehicle)
- Non-motorized vehicle
- motor_vehicle=* (category: any motorized vehicle)
- Double-tracked (category: motor vehicles with more than 2 wheels/more than 1 track)
- motorcar=* automobiles/cars
- motorhome=* (a motorhome)
- tourist_bus=* describes a bus that is not acting as a public transport bus service
- goods=* (light commercial vehicles; e.g., goods vehicles with a maximum allowed mass of up to 3.5 tonnes)
- hgv=* (heavy goods vehicle; e.g., goods vehicles with a maximum allowed mass over 3.5 tonnes)
- agricultural=* (agricultural motor vehicles; e.g., tractors) that have additional restrictions; e.g., a 25 km/h speed limit)
- atv=* a.k.a. Quad (bike) (Restricted to or permissive for vehicles 50 in, 1.27 m, or less in width) still in proposal stage. You may want to use maxwidth=1.27 instead.
- By use
- psv=* (public service vehicle)
- hov=* (high-occupancy vehicle/carpool, varies by location; e.g., at least one passenger)
- car_sharing=* (car sharing vehicles)
- emergency=* (category: emergency motor vehicles; e.g., ambulance, fire truck, police car)
- hazmat=* (motor vehicles carrying hazardous materials)
- disabled=* (holders of blue badge, UK, or other such disabled persons' permit. Used on traffic signs to exempt said group from access restrictions; not just regarding parking)
Not in the list
- Hybrid cars, electric vehicles, other no-emission vehicles (e.g., hydrogen powered).
- Car hire with driver.
- road_train (should that be "hgv_caravan" ?).
- Other configurations of hgvs - B-double, double-B doubles and 2AB quads.
- Hand cart: a cart that is pulled or pushed by one or more people.
- Auto rickshaw: a motorized version of the traditional pulled rickshaw or cycle rickshaw.
- access=* (category: any water-based transportation mode)
- boat=* (covers small boats and pleasure crafts, including yachts)
- motorboat=* (boats and yachts using motor, on also for sailing boats using the motor)
- sailboat=* (boats and yachts using sails, on doing way with sail, not using the motor (according to the definition of the Colreg))
- canoe=* (boats without sail or motor, such as small dinghies, canoes, kayaks, etc.)
- fishing_vessel=* (covers fishing vessels of any size)
- ship=* (covers commercial vessels of any size and any trade)
- passenger=* (ships carrying passengers, either as a scheduled service (ferries, etc.) or as cruise)
- cargo=* (any type of cargo ship)
- bulk=* (covers all dry bulk cargo)
- tanker=* (covers all wet bulk cargo, including compressed gas)
- tanker:gas=* (compressed or liquefied gas)
- tanker:oil=* (crude oil and oil products)
- tanker:chemical=* (all other products in tanks)
- tanker:singlehull=* (special coverage for single hull as most of Europe and US have more restrictive rules for single hull tankers than for double hull. The general tag is for double hull if this tag is in use.)
- container=* (collective tag for general cargo)
- imdg=* (dangerous cargo covered by the International Maritime Dangerous Goods Code, IMDG)
- isps=* (International Ship and Port Facility Security Regulation.)
- boat=* (covers small boats and pleasure crafts, including yachts)
As suggested, see discussion.
Access can be tagged on facilities, typically including
- building entrances, which can be used to model that different entrances are for different groups of users,
- buildings themselves,
- amenities, often used on amenity=parking with restrictions to private (e.g. company employees only) or customers (people visiting a shop),
- leisure entities, such as leisure=sports_centre or leisure=playground where private describes a closed user group, e.g. members only or children of a particular school.
Nodes, ways and areas
Tags of "access" group can be used for nodes, ways and areas. There are different priorities in OSM-community, where to put access tag: to area (usually it is a square, which have some specific conditions of access), to line (usually it is roads inside square) or to node (usually it is gate in barrier, which surrounds square, where there is a possibility to enter the area). Note that access tags mark legal status of territory and barriers and warning signs are only physical reflections of restrictions in area. In such manner, area with private status should have appropriate values, even there is no surrounding barrier or it is broken. Note, that different entrances can have different access values and different roads inside area can have different access values too. For example, we have area with permissive access - so we mark it with access=permissive. But there are several entrances, one of which is designated for all people, and other - only for persons, which have key. So we mark one entrance with access=permissive and other - with access=private. Another example - we have botanical garden with permissive access, which have roads, which are designated for public, and roads, which are designated only for staff of garden. In such case we have access=permissive at one roads and access=private (or access=no) at another.
When you are tagging some area, it is your decision, where to put "access" tags: to area, to entrances or to roads inside area (because nobody can bring you to add some tags somewhere), but removal of correct tags, which were put but someone else, is a mistake (and is close to vandalism). If you like to put tags to areas, do it, if you like to put tags to roads inside areas, do it, if you like to put tags to entrances, do it. But don't delete tags from type of elements, which you don't like.
