Tagging express lanes

Hi, I have a question. I want to add the tag hov=yes for express lanes in California. What is the best way to go about it? In some places, express lanes are separated by plastic bollards, and we have separate lanes for them in OSM (Example SR 91 Express Lanes Way: ‪91 Express Lanes‬ (‪482532984‬) | OpenStreetMap).

Additionally, in scenarios where there are two lanes and both are designated HOV lanes, should I use hov:lanes=designated|designated?

Technically, that would be correct, though routers are more likely to understand hov=designated in the case where the entire roadway is for HOVs only. Think of *:lanes as the syntax for varying the value from one lane to another.
