[Talk-us] HOV lane tagging

[Elliott Plack]

Jack,

Good question. I am curious about the answer as well, specifically
regarding bicycle lanes, which can be added using this method.

Setting a right side bike lane to ...yes|designated doesn't preclude other
vehicles from accessing the right lane, as you said.

I thought about adding |no for regular access, but wouldn't that general
access contradict the other tags?

The Mapbox data team has been doing lots of turn lane tagging around the US
[1], so perhaps a member of the team there can provide insight on this.
