Access values describe restrictions on the use of highways and other transportation routes (railways, waterways), as well as facilities such as buildings, building entrances, amenities and leisure entities.
Access values describe legal permissions/restrictions and should follow ground truth e.g. signage or legal ruling and not introduce guesswork. It does not describe common or typical use, even if signage is generally ignored.
Access restrictions can be very complex, for instance including type, direction, size, and time of traffic - but with care most can be coded as described here. Fortunately standard simple cases are usually also quite simple to tag.
In case of complex situations it may be wise to add a note describing exact signage, especially if it does not follow legal signage rules or rare combinations.
Car parking without public access
Road with restricted access
There are some roads with restricted access - roads in factory complexes, on military bases or driveways with clear out of bounds signage or barriers. To mark road as as restricted to only private access, add access=private.
Note that it notes access, not ownership. Many privately owned roads are freely accessible for the general public without prior permission- in such case access=private would be wrong and it may be access=permissive if the owner can revoke this permission at their own discretion. Privately owned roads can even be -depending on the legislation- public roads in the sense that the owner has a legal duty to allow the general public access and is not free to revoke this permission (access=yes).
Road where residents, pedestrians and cyclists are allowed
It is possible to mark road as accessible for some specific types of traffic. For example a road where only local residents may drive vehicles, but cyclists are still allowed.
To tag this one may use following combination of access tags:
- vehicle=private - access for vehicles in general is not allowed, but some narrow range may still use it
- bicycle=yes - cyclists may use it
Example of more complicated situation
A service road (highway=service) with the tag access=customers implies that the road can be used only by customers. There are no other restrictions: customers can arrive by any form of transport, at any time, etc.
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 instead of access=yes.
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=no, bus=yes means that only buses are allowed to enter (for example a road only for buses)
- access=yes, motor_vehicle=no means that all transport modes except motor vehicles 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. Note that this tagging at the same time prohibits the way for all not explicitly tagged modes of travel, e.g. bicycles and horses which is usually a mistake in combination with forestry. Therefore it is better to use the specific tags and not the general access=* for limitations.
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
- foot=* (pedestrians)
- dog=* (whether dogs may be walked here by (usually) pedestrians; in most jurisdictions assistance dogs such as guide dogs are exempt)
- horse=* (horse riders)
- Moving with any vehicle
- vehicle=* (category: any vehicle)
- Non-motorized vehicle
- Motorized vehicle
- motor_vehicle=* (category: any motorized vehicle)
- motorroad=* (motorway-like access restrictions on roads that are not motorways)
- motorcycle=* (a 2-wheeled motor vehicle, allowed to drive on motorways)
- moped=* (motorized bicycles with a speed restriction; e.g., at most a 50 cc engine or max. speed of about 45 km/h)
- speed_pedelec (electric bicycles capable of a higher speed (often up to 45 km/h). Required to have license plate, helmet, insurance,...)
- mofa=* ("low performance moped", usually with a maximum design speed of 25 km/h)
- Double-tracked (category: motor vehicles with more than 2 wheels/more than 1 track). Please note double_tracked_motor_vehicle=* is suggested in Key:motorcar but neither widely used nor officially approved; it would allow one single tag instead of ten tags (one for each of the child types).
- motorcar=* automobiles/cars (in restrictions it can imply the generic class of double-tracked motorized vehicles)
- motorhome=* (a motorhome)
- tourist_bus=* describes a bus that is not acting as a public transport bus service, usually for long-distance travel but not always
- coach=* a bus for long-distance travel, not part of 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)
- hgv_articulated=* articulated heavy goods vehicle
- agricultural=* (agricultural motor vehicles; e.g., tractors) that have additional restrictions; e.g., a 25 km/h speed limit)
- golf_cart=* (golf carts and similar small, low-speed electric vehicles)
- 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). Note that emergency vehicles are generally not restricted by *legal* access rules. For places explicitly designated for emergency access consider emergency=designated.
- hazmat=* (motor vehicles carrying hazardous materials)
- hazmat:water=* (motor vehicles carrying materials which can pollute water)
- 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)
- Moving without a vehicle
Not in the list
- Hybrid cars, electric vehicles, other no-emission vehicles (e.g., hydrogen powered). See discussion.
- Car hire with driver.
- roadtrain=*: Road train (should that be "hgv_caravan" ?).
- lhv=* - longer heavier vehicles (long trucks)
- 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.
- Kei Cars - Small cars which have limited size, weight, and engine power. Their limited size differentiates them from "regular" motorcars for road access in some countries, such as Japan.

- 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.)
As suggested, see discussion.
List of possible values
The tag takes the form access=*, where * can be any of the following:
|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, for example, at a vehicle no-entry sign, use a more specific restriction like vehicle=no or motor_vehicle=no over the general key access.|
|private||Only with individual permission|
|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.|
|permit||Open only to people who have obtained a access=privategranting them access, but permit is ordinarily granted. If permit is hard to obtain, then it is typically|
|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.
Sign text in different languages:
|delivery||Only when delivering to the element. For example motor_vehicle=delivery on a highway=pedestrian. Status: "approved"|
|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, in general this means that there is a (explicit) sign saying something like "pedestrians allowed", or a pedestrian icon.|
|use_sidepath||Used to indicate that a mapped parallel way -that belongs to the same road- must be used instead (mostly acting as access=no with some exceptions). A road can legally consist of several ways, such as a single or dual carriageway with parallel tracks for cyclists, mopeds, pedestrians and/or equestrians. Used in countries where these classes must use specific parallel ways when present (following traffic rules, sometimes in conjunction with traffic signs). This tag should only be used to limit specific transport modes (e.g., 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. Note that bicycle=no is also commonly used where dismounting and pushing bicycle is legal.|
|agricultural||Only for agricultural traffic. Note a closed farmer's access track would be access=private rather than access=agricultural unless the track is explicitly open to any vehicle used for agricultural purposes, e.g: . Status: "approved"|
|forestry||Only for forestry traffic. Status: "approved"|
|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), e.g.:,|
|unknown||The access conditions are unknown or unclear. For the access key, where users might assume access rights by definition or some default, this makes it explicit that the actual situation is not known (since an absent access tag might also be mistaken by some users as being compliant to an assumed default). These tags should therefore not be removed without replacing them with a better alternative. For example data consumers typically assume that amenity=parking without access tags is public, and when mapping from aerial imagery some parking will be likely (but not certainly) access restricted, in such cases tagging them unknown would be a good idea.|
|user defined||All commonly used values according to Taginfo|
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.
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.
Access time and other conditional restrictions
- For a full description and more examples, please see the conditional restrictions page.
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.
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.
- maxaxleload=* - The legal maximum axleload in metric tonnes.
- maxheight=* - The legal maximum height in metres
- maxheight:physical=* - The maximum height in metres
- maxlength=* - The legal maximum length in metres
- maxspeed=* - Specifies the maximum legal speed limit on a road, railway or waterway (km/h by default, mph where specified)
- maxstay=* - Maximum time you are allowed to stay somewhere. (maximum parking time)
- maxweight=* - permissible maximum actual weight
- maxweightrating=* - Legal access restriction for vehicles with a max allowed weight above the specified weight in metric tonnes.
- maxwidth=* - The legally restricted maximum width of a vehicle (also note width=* for the physical width of the entire road.)
- mindistance=* - minimum trailing distance, often as mindistance:hgv=* on old bridges or in tunnels
- minspeed=* - Specifies the minimum speed limit on a road, railway or waterway.
- maxdraught=* - Specifies the maximum boat draught
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. If possible reverse the direction of the way and tag with oneway=yes.
- Not normally used, as two-way traffic is the default. Use only where 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 cyclists are allowed to travel in both directions on a oneway street.
- When a road is accessible for bicycles only in forward direction e.g. a road has a cycleway next to it that must be used.
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.
- Main article: Turn restriction
- bicycle=yes The public has a right of way when travelling on a bicycle.
- horse=designated The route is designated for use by equestrians.
- motorcycle=unknown It is unclear whether motorcycles can use this section.
- motorcar=private The owner must give access to cars on an individual basis. Access by car is private; e.g., on a private road.
- goods=no General goods vehicle traffic is not allowed.
- hgv=no Heavy goods vehicle traffic is not allowed.
- boat=no Waterway is not available for boat traffic.
- oneway=yes + psv=opposite_lane The street is one way for cars but there is one opposite lane for buses and taxis.
- maxweight=7 The weight limit is 7 tonnes.
- maxaxleload=3.5 The restricted weight limit per axle in tonnes; e.g., 3.5 t.
- maxheight=2.5 The maximum vehicle height is 2.5 meters.
- maxdraught=1 The maximum boat draught is 1 meter.
- maxspeed=110 The maximum speed limit is 110 km/h.
- maxspeed=55 mph The maximum speed limit is 55 mph.
- maxstay=14 days The maximum stay permitted; units in the tag as either hour/hours or day/days.
A one-way street with a cycle lane in the opposite direction:
Mismatch between law and de facto status
In some regions, at least for some modes of transport there is a complete mismatch between what is officially legal access and what is actually treated seriously. Currently OSM has no known good method to tag this (bicycle=no bicycle:de_facto=yes?).
Currently some mappers put actually enforced status into access tags, rather than what is legal.
Possible tagging mistakes
- Implicit default values
- Conditional restrictions - To tag restrictions being dependent on a condition
- access=designated - different explicit administrative designations (like footway, cycleway, bridleway)
- highway=cycleway - For designated cycleways
- highway=footway - For designated footpaths, i.e. mainly/exclusively for pedestrians
- highway=bridleway - A way intended for use by equestrians
- Approved features/More access keys and values
- male=*, female=*, unisex=* - for marking objects as limited to specific gender, common with for example toilets
- min_age=*, max_age=* - Minimum / Maximum age for a person to enter or use a facility
- Restrictions - Restrictions that apply to the use of an element
- United States/Tags#Access restrictions – translates text-based "No …" signs into access tags
