Under what circumstances may a bus use a high occupancy vehicle lane?

The high occupancy vehicle (HOV) lane is designed to encourage carpooling and reduce traffic congestion by allowing vehicles with multiple passengers to travel more efficiently. Buses are treated differently in this context because they are designed to carry a large number of passengers, making them significant contributors to reducing the number of vehicles on the road.

Buses can operate in HOV lanes at any time because they are inherently capable of transporting multiple passengers, and their use promotes public transit and reduces overall traffic. Therefore, regardless of their occupancy level, buses are permitted to utilize these lanes to enhance transit efficiency and encourage more commuters to use public transportation.

Other occupancy conditions related to personal vehicles do not apply to buses, which is why the option that states buses may use HOV lanes at any time is appropriate. It is essential for jurisdictions to support public transit by allowing buses access to these lanes, thus fostering better mass transit solutions and alleviating congestion on regular lanes.
