Key:road_marking

 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
left	Your lane must turn left.	See also turn=* (or turn:lanes=*) for tagging entire turn information beginning from first indication by sign and road marking to the final junction node.
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=*
