<p>I've been using the "turn:lanes:*=none;slight_right" & "slight_left;none" tags to indicate which side a new lane has been added on a highway when going from 1 to 2 lanes (sometimes "slight_left;slight_right" if the original lane is centered between the two
new lanes). How else are people to properly identify which side the new lane is being added to? Take a look at this way ( <a id="LPlnk707412" href="https://www.openstreetmap.org/way/419799887" class="OWAAutoLink">https://www.openstreetmap.org/way/419799887</a>
) and take a look at the Bing imagery and look at the 'turn:lanes:forward' tag, and you'll see how this can, and would be valid. It's allowing the router to know that a new lane is being added when combined with the next way (

https://www.openstreetmap.org/way/419799886</a> ) which has the "lanes:forward=2" tag. It also allows the routers to properly tell people to get in the left lane if just ahead, there's a left turn they need to make.<br>

<div>I haven’t seen “none;slight_right” as a value and am not sure how that should look different than “slight_right” by itself. However “none” is a value listed in the wiki [1] and I use it a lot as I find multiple vertical bars hard to manually count/edit
but I can see and count things like “left|none|none” easier than “left||” when editing in JOSM.

Hey James,
<div class=""><br class="">
</div>
<div class="">(Disclaimer: I work for Mapbox, but I am not part of the team that is doing the lane tagging, and can’t speak for them).</div>
<div class=""><br class="">
<div class="">I do need to know more about your concern: Is `none` as part of a multiple turn lane option documented anywhere? </div>
<div class=""><br class="">
</div>
<div class="">I’m asking because we are adding turn lane tagging to iD this summer [1], so I have been thinking a lot about turn lanes, and I have read through a lot of wiki pages and discussion pages, and this is the first I’ve seen anybody using a tag like
`turn:lanes:backward=none;slight_right`.</div>
<div class=""><br class="">
</div>
<div class="">It’s really important to me that I get this as correct as possible, because I can’t have iD overwriting somebody’s valid lane tagging. I’d like to be able to show visually what a tag like `none;slight_right` means on the ground.</div>
<div class=""><br class="">
</div>
<div class="">Thanks, Bryan</div>
