I use psv:lanes, but there are no real bus lanes here, it's called buslane, but law says taxis can also use it.
HOV is different. Psv lane is for buses, taxis, etc, exact rules differ per country. Here police, motorcycles, ambulance, garbage trucks can lso use it. There are cameras which check the license plate of the cars in the lane, and you automatically get a fine if you shouldn't be there
