 | This tagging is highly experimental. |
Road surface markings represent the physical presence of road markings mapped with ways.
Unlike similar keys, such as turn=*, lanes=* and Relation:restriction which annotate highway ways, road_marking=* tags describe the markings themselves. However in most instances it may be possible to infer them from the tagging on the highway.
Note: Do not draw them in isolation from other elements (such as lanes). It will just be garbage data. It should be attributed within the way element (way=*). Drawing is a violation of the agreement(Tagging for the renderer). - Best practice tag examples
Values
| Value | Description | Notes | Mapillary / OpenStreetCam / other photo example | In-map example |
|---|---|---|---|---|

|
|
| right | Your lane must turn right. | |||
| left;right | Your lane must turn left or turn right. | |||
| left;through | Your lane must turn left or go straight. | |||
| right;through | Your lane must turn right or go straight. | |||
| left;right;through | Your lane must turn left or right or go straight. | 264040303 264040303

| dash | Only use this for dashes that demarcate lanes. | See also: change=* | 
|
|
| dashed_yield_line | When yielding for a yield sign, stop here. This line is perpendicular to your movement. |
See also highway=give_way | ||
| solid_stop_line | When stopping for a red light, stop here. This line is perpendicular to your movement. |
See also highway=stop / traffic_sign=stop | ||
| solid_road_divider | A solid line dividing the two carriageways of the road | |||
| solid_lane_divider | There is a lane on each side. | See also: change=* | 
|
|
| solid_road_edge | There is a lane on exactly one side except when extending an onramp's gore triangle with a line. |
|
||
| gore_chevron | A chevron inside an onramp/offramp gore triangle | 
|
||
| solid_crossing_edge | A solid line along an edge of a pedestrian crossing | |||
| bus | Bus lane road markings. Depends on the local usage and language; usually a text (BUS). | See also: bus:lanes=* & lanes:bus=* | ||
| bus_stop | Bus stop road markings. Depends on the local usage; can be a box, a text (BUS), zebras, etc. | |||
| pedestrian_crossing_rectangle | Rectangle of pedestrian crossing. It may be possible to use area:highway=* instead. | See also: crossing=* |
