How are fares calculated?

When riding Marin Transit and Golden Gate Transit buses, Clipper deducts the maximum fare from your starting zone and then refunds the difference when you tag your card to the card reader upon exiting. This means you must tag your card to the card reader upon entering AND exiting the bus to ensure you' re only charged for the distance you travel and that Clipper applies any appropriate discounted fares and transfers.

Do I get any discounts for using Clipper?

Yes, adult riders will always get a 10 percent discount over paying with regular cash. Passengers with a Youth, Senior or RTC Clipper card receive the same 50 percent discount they do when paying with cash.

If I get on the wrong bus and tag my card can the bus driver "un-tag" me?

No. Once the card has been tagged at the card reader, the bus operator cannot un-tag your card. You should ask the bus operator for a courtesy transfer.

Do I need to ask for a paper transfer?

If you are transferring within Marin Transit/Golden Gate Transit or to or from another transit agency that accepts Clipper, you do not need a paper transfer. Clipper keeps track of your rides and automatically grants you appropriate transfer discounts. If you tag your second bus within the appropriate timeframe, you will be granted your transfer. If you tag after that period, an additional fare will be deducted from your card.

Can I use my Clipper card on all Marin Transit routes?

Clipper is accepted on all Marin Transit routes except the Muir Woods Shuttle (Route 66/66F). Visit Marin Transit for more information about paying your fare for the Muir Woods Shuttle.
