|If one or more lanes of the road are restricted to high-occupancy vehicles (typically vehicles with 2+ occupants, although this varies by jurisdiction). Most useful if entrance/egress is permitted at any point along the route; if entering or exiting the HOV lane(s) is only permitted at certain locations, modeling the HOV lane(s) as separate ways is preferable.

=== Mapping ===
A highway's ways should be mapped and split exactly where the extent of a number of lanes becomes available.
The way tagged with lanes from a way approaching or leaving an intersection node should extend all the way to the intersection node, even though the physically marked lanes do not because it is an intersection.
==== Street ====
Here, a residential street transitions from 2 lanes on the right to 3 lanes approaching the intersection.
There is a turn lane transition area marked with dashes where the lane begins to form, however, since it is not fully formed, the way that includes three lanes does not extend to include it.
The way only extends to where the full 3 lanes are present and available to use. In this example, this is also marked by start of the solid line dividing the turn lane and the through lane.
