Golden Gate Bridge Carpool Toll
Carpool across the Golden Gate Bridge for just $5.75 per crossing - saving $3.00 vs solo FasTrak. Requires 3+ occupants and a FasTrak Flex transponder.
Eligibility Requirements
3 or more occupants
The driver plus at least 2 passengers. Children of any age count. This is stricter than some Bay Area express lanes which allow 2+ occupants.
FasTrak Flex transponder
You need the Flex model (not the standard FasTrak). It has a physical switch with positions 1, 2, and 3. Set it to 3 before crossing. Free with a $25 prepaid account balance.
Switch set to 3 position
The toll system reads the switch position electronically. If your Flex tag is set to 1 (solo), you will be charged the standard $8.75 rate even if you have passengers.
How the FasTrak Flex Tag Works
The FasTrak Flex transponder has a physical switch on the front with three positions:
Important: On the Golden Gate Bridge, only position 3 qualifies for the carpool discount. Position 2 gets the standard rate. Always set to 3 when you have 3 or more people in the car.
