The current guidance for using this tag is "highway which has lanes=* with any value below 2, e.g. 1 or 1.5". There are many two lane roads that do not allow passing by using the opposite traffic flow lane (marked by a double yellow center line in the United States). In order to legally pass, one must wait for the person ahead of him or her to pull out into a turn-out.
I feel that these should be marked on these two lane roads much the same as on a 1 or 1.5 lane road since passing points will be restricted.

Why only on nodes?
Wouldn't it make more sense to allow tagging on ways as well? Also because it would open the possibility to give indications about the position (right/left) which are meaningless for nodes because of the lack of direction. --Dieterdreist (talk) 11:09, 4 September 2018 (UTC)
- Passing places are not long, most of them are just long enough to squeeze in a car and caravan ... just, some would be a real challenge as a largish car only just fits. You have to come to a complete stop to let others pass in either direction. You cannot keep moving as you would with an extra lane of any real distance. Which side it is on does not really matter, if you see an oncoming vehicle or a vehicle coming up behind you then you stop at the next passing place. Warin61 (talk) 12:07, 4 September 2018 (UTC)
- I agree they are not long, and are compared to the road "spots". A car and a caravan are 8-10 meters, so while this could technically be a short way without problems, it would fragment the road into segments between passing places, not so beautiful. I agree to require nodes :) The micro-location could be indicated parametrically (cardinal direction) to give an idea about the side of the road (or whether there is a symmetrical widening). --Dieterdreist (talk) 12:19, 4 September 2018 (UTC)
