Riders may need to transfer to another bus or a different transit agency at some point along their journey. The easiest way to transfer, either between AC Transit routes or other transit agencies in the Bay Area, is to use Clipper. Keep your Clipper card loaded and tag the reader upon boarding; if a transfer discount is offered, it will be instantly applied, and the correct fare will be deducted automatically. Riders making frequent transfers should consider purchasing a pass for unlimited rides or paying with your mobile device to tap into the benefits of pay-as-you-go fares.
Transferring within AC Transit
Transfers between AC Transit buses require additional fare in most cases.
Transbay-to-Local : Clipper users receive one free transfer to a local AC Transit bus within two hours of tagging on a Transbay bus. Riders paying with their mobile device can transfer to a local bus within two hours of activating their Transbay ticket. Free transfers are not available when paying with cash.
Local-to-Transbay : Clipper users and paper Day Pass holders can transfer from a Local to a Transbay bus by paying an “upgrade fare” as noted on the Fares page. The upgrade fare is automatically applied when using Clipper; paper Day Pass holders must swipe their pass on the Transbay bus, then add the appropriate fare to the fare box. Riders paying with the mobile device must purchase and activate a Transbay ticket for boarding first a Local bus then a Transbay bus within two hours.
Tempo and All-Nighter
Riders on Tempo Line 1T transferring to other AC Transit lines must pay single ride fare or use a valid pass to board. However, between the hours of midnight and 6:00 am riders transferring between Tempo and All-Nighter routes at transfer points do not have to pay an additional fare. If transferring to the All-Nighter, riders should show their Tempo proof of payment. If transferring to Tempo, riders should ask the All-Nighter operator for a free transfer, which must be in the rider’s possession for the duration of their Tempo ride.
Valid passes and transfers from participating agencies are accepted by AC Transit for one local fare credit at intersecting, or transfer, points. If you are transferring to another participating agency, ask your AC Transit driver for an “Interagency Voucher” when boarding. Present this to the other agency’s driver for a free transfer or discount when applicable. Transfer discounts are automatically applied when using Clipper. See the list of agencies below for more details.
