I think you shoulld also look at http://wiki.openstreetmap.org/wiki/Key:road_marking [http://wiki.openstreetmap.org/w/images/5/5f/Road_marking_left.jpg]<http://wiki.openstreetmap.org/wiki/Key:road_marking> Key:road_marking - OpenStreetMap Wiki Unlike similar keys (e.g. Key:turn) which annotate highway ways, road_marking ways describe the markings themselves.

I looked at some ways tagged like that and they all seem to be barriers between large roads (motorway,trunk), e.g. http://www.openstreetmap.org/way/118699380 This way http://www.openstreetmap.org/way/117153052 is also tagged type=oneway. No idea what that would mean. My understanding so far: The tag makes no sense, editors use it instead of barrier=hedge or something similar. In Germany we have a traffic_sign that warns drivers when the white line is missing, e.g. because the road was recently repaired. I think if one wants to map this, it should be an attribute for the existing highway, not a new way. I think the tag centreline=* is used for that (130 times). Gerd Hi, OSM will always surprise me. Here in Belgium, what is called the "white line" is of uttermost importance. And I suppose in most other countries too. I've been looking for it in vain in the wiki and now it surges. But, first of all, we must distinguish a striped line, as said above, and a continuous white line. What I say relates to the continuous line. That line means: * that overtaking is forbidden * that turning left is forbidden (for right side driving) * and of course also that U-turn is forbidden * but also that turning left is forbidden when coming from a crossing Hence, it may replace many complicated turn restrictions very simply. And instead of "replace", I should say "add" because they're often missing. (because making relations is difficult) For a simple 2-lane road, it would best be a tag of the highway, not an additional line. The downside is that it would produce many splits. The most surprising is that it seems to be a one man's tagging assimilated to a hedge !!! Cheers André.
