Because back in the day, people complained about the spelling and that it had 
to be in the 'British' way.  So, it's under 'centre_turn_lane'.

A two-way center turn lane is a normal-width lane in the middle of a road that

For the ‘dashed line’ center turn lanes: what you do makes sense to me too. I 
have used center_turn_lane=yes in the past, but that is not documented and I 
wouldn’t encourage it. This way it fits nicely into the lanes schema.

The turn lanes plugin seems to support this nicely:

 — even though the center lane is rarely marked with left turn arrows, as 
suggested by the turn lane style.

Hello all,
Me and my Telenav colleagues are editing lane numbers in Detroit area. We found 
some cases that looks like this (42.43651692568901, -83.51102781049859):

Our question is: what is the central lane used for and how do we map it?
Should we count it as a separate lane and have 3 lanes in this case (one for 
each direction and one for both directions)

or have only 2, one for each direction?


Thank you,

Texas often includes the arrows as well.

Suicide lanes are something else: They're passing lanes in both directions,
not continuous bidirectional left turn lanes.  Historically, they were like
the reversible left turn lane, only with a dotted yellow line and no solid
line.  Neither direction had right of way.  This concept is, as far as I'm
aware, obsolete in the US.  Typical configuration is now 2+1, with the
center lane being one of the two lanes for the uphill direction, signed
KEEP RIGHT EXCEPT TO PASS, with one downhill lane and the centerline
indicating the downhill direction can use the center lane to pass.  With
the mass repave-the-entire-state push Oregon recently completed, I don't
think even the historical remnants of these (where you could still see the
faded remains of the former suicide lane yellow stripes) remain at this
point (whereas previously you could see hints and traces of the old yellow
line where the white line is on the uphill side is on Oregon's 3-lane
highways).

That's because in Europe they usually have those left turn arrows. :-)

In that specific case, it is not a traffic lane per se, it a 'left turn
lane' when leaving the roadway, and a 'merge' lane if one is making a left
turn onto the roadways. It also acts as a traffic separator.

I used to live in that area - there is an *exceptional* piece of weirdness
at ( 42.5665399,-83.0309866 ).
