Two traffic lanes.

Examples

Lanes available for motorised traffic
Photo Tags Remarks
lanes=2 A two-way residential road with two lanes. Consider additional tagging with parking:both=lane + parking:both:orientation=parallel and other street parking tags.
lanes=2 on the first line

lanes=2 on the second line Each direction individually

A dual 2-lane highway, represented by two ways as there is a physical divider between them (each with oneway=yes).
lanes=2

lane_markings=no

Two-way road without marked lanes, but it has 1 lane in each direction. White markings on sides are delineators indicating boundary of the road. These lines do not, however, mark the individual lanes, only the edge of the road, so lane_markings=no should be used.
Lanes available for non motorised traffic
cycleway with two marked lanes highway=cycleway

lanes=2

A cycleway with two marked lanes. (Attention, as described above and seen in the example: Lanes#Crossing_with_a_designated_lane_for_bicycles bicycle lanes only counts for tag lanes=* if the cycleway has a physical separation and it is therefore mapped as a separated OSM way)
piste:type=nordic

piste:lanes=2

A piste route with two classic xc lanes. Avoid just lanes=* since the piste often shares way with a highway=* for which the number of lanes might not be applicable.
