I explained this several posts ago. It is an additional lane, running for perhaps a quarter mile, sometimes longer, that any vehicle which is holding back some number of other vehicles is obligated to use so that those following vehicles may pass.

Sorry, didn't get that this is not climbing lane (my fault). In New<br>
England, extra lanes that one would associate with "slow vehicle" are<br>
99% on hills.<br>

<br>
You say "turnout". But physically, is it just an additional lane that<br>
appears, and (more or less) one is obligated to move right one lane into<br>
it if you're in the way?<br>
<br>
Do any routers do anything? An example of how the data would be used,<br>
or how you think it would be used in an ideal future might be<br>
illuminaing. Perhaps one's car computer could notice from forward<br>
radar that there is obstructing traffic and query osmand and give you a<br>
notification that the road becomes multilane in some distance, so you<br>
can get ready to blink to get the obstructor to move over if they stay<br>
left? In that case, I wonder about the difference between a change to<br>
two lanes (perhaps because the row is wide enough and the long-term plan<br>
is 2) and a specific place like you describe.<br>
