Carpools and other eligible vehicles can use carpool lanes at all Bay Area toll plazas and Bay Area Express Lanes to bypass traffic congestion and enjoy a faster, more reliable commute. There are different rules and requirements, depending on whether you are traveling in a bridge carpool lane or an express lane.
Carpooling Across Toll Bridges
Carpools, motorcycles and eligible clean air vehicles (CAVs) using carpool lanes during designated commute hours on Bay Area bridges may receive discounted tolls.
Carpool lanes are identified with white diamonds on the pavement and signage above and alongside the roadway.
STATE-OWNED BRIDGES
(Antioch, Benicia-Martinez, Carquinez, Dumbarton, Richmond-San Rafael, San Francisco-Oakland and San Mateo-Hayward)

If you drive through a carpool toll lane without a FasTrak toll tag, an invoice for the full amount of the toll will be sent to the vehicle's registered owner, even if you meet the occupancy requirements for the carpool lane.
