On the Golden Gate Bridge
Yes. To be eligible to receive the discounted carpool toll rate at the Golden Gate Bridge, you must have a FasTrak account in good standing and travel through a designated carpool lane. Eligible carpool vehicles include: (1) two-axle vehicles with three or more people; (2) motorcycles, including three-wheeled motorcycles; and (3) buses.
Eligible clean air vehicles with fewer than 3 people, two-seat vehicles, and vehicles with rear axle dual tires do not qualify as a carpool on the Golden Gate Bridge.
On All Other Toll Bridges
Yes. To be eligible to receive the discounted carpool toll rate at the state-owned toll bridges, you must have a FasTrak account in good standing and travel through a designated discounted carpool lane. Eligible carpool vehicles include any vehicle that meets the minimum number of occupants (two or three, depending on the bridge), motorcycles and clean air vehicles displaying valid clean air vehicle decals (purple or red). If you drive through a carpool toll lane without a FasTrak toll tag (even if you meet occupancy requirements for the carpool lane), a violation notice will be sent to the vehicle's registered owner. It is a violation of the toll evasion statutes under California Vehicle Code Section 23302 et seq. and Streets and Highways Code Section 30843 to fail to pay the established bridge toll.
