[OSM-talk-be] Lanes & turns from wich side you start to count?

[Gerard Vanderveken]

The order is  from left to right as seen in the direction of the traffic 
<https://wiki.openstreetmap.org/wiki/Lanes#Two_driving_directions>, not 
the road (arrow).
There is a style for Josm 
<https://wiki.openstreetmap.org/wiki/Lanes#JOSM>, that visualises the road.
