Using Clipper on Sonoma County Transit

You can use Clipper on all Sonoma County Transit buses.

Clipper automatically figures out the cost of your ride, including all discounts and transfers. See Fares and passes for more information on the types of value available.

If you are paying for your ride with cash value, you must have a minimum balance of $3.00 on an adult Clipper card, $2.75 on a Youth Clipper card, or $1.50 on a Senior or RTC Clipper card.

To use Clipper on Sonoma County Transit, locate the Clipper card reader at the front of the bus. Tag your card by holding it flat against the Clipper logo on the reader, and wait for the beep and green light. The card reader either will verify that you have a valid pass and display the expiration date or will deduct the cash value fare and show your remaining balance.

If your card balance is low, the reader will beep twice and display a yellow light. You can still board the bus, but you will need to add value to your card before your next trip. If you do not have enough value on your card, the reader will beep three times and display a red light, and you will not be able to pay your fare with Clipper.

Important! You must "tag off" when you exit the bus to ensure you are charged the correct fare. 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. Note that each bus only has one card reader, located at the front of the vehicle. Clipper customers will need to exit at the front of the bus to tag off.
