The Clean Air Vehicle decal program ended September 30, 2025. Starting October 1, 2025 Clean Air Vehicles can use HOV lanes only with the required number of occupants. More information is available on the Air Resources Board website(opens in a new window).
Carpool lanes, also known as High Occupancy Vehicle (HOV) lanes, allow carpools, vanpools, buses, and motorcycles to drive in them during their designated commute hours. Other vehicles are not allowed. HOV hours of operation and carpool occupancy requirements vary by lane. During non-commute hours, carpool lanes revert to general traffic use.
Express Lanes allow vehicles to pay tolls, pay discounted tolls, or travel toll-free based on the lane’s operating requirements. Tolls increase as traffic increases and decrease as traffic decreases.
