FASTRAK TOLL TAGS
FasTrak offers three types of toll tags: standard FasTrak, FasTrak Flex, and FasTrak CAV.
Standard FasTrak

The standard FasTrak toll tag works at all toll bridges and in all Bay Area express lanes, and it also can be used to pay for parking at San Francisco International Airport.

If you have a standard FasTrak toll tag, it will continue to work, and you don't need to get another tag unless you want to travel toll free as a carpool or motorcycle in express lanes or get a clean air vehicle (CAV) discount.


FasTrak Flex

The FasTrak Flex toll tag has a three-position switch to signal whether you are traveling alone or as a carpool. The FasTrak Flex toll tag works at all toll bridges and in all Bay Area express lanes, and it also can be used to pay for parking at San Francisco International Airport.

A FasTrak Flex toll tag is required for carpools, motorcyles, and eligible CAVs* to travel toll free in the I-580, I-680 Contra Costa, and SR-237 express lanes.

If you do not use express lanes as a carpool, motorcycle, or eligible CAV, a standard FasTrak toll tag will serve all your needs. The vast majority of FasTrak users only need a standard FasTrak toll tag.


FasTrak CAV

The FasTrak CAV toll tag is only issued to eligible clean air vehicles and is required for discounted single-occupant CAV travel in the SR-237 express lanes. The FasTrak CAV toll tag also has a three-position switch to signal whether you are traveling alone or as a carpool. The FasTrak CAV toll tag works at all toll bridges and in all Bay Area express lanes, and it also can be used to pay for parking at San Francisco International Airport.

When traveling as a single-occupant vehicle in the SR-237 express lanes, eligible CAVs will receive a 50% discount off the toll if they use a FasTrak CAV toll tag. It is the only toll tag that will communicate the correct discount to roadside equipment.

Use the chart below to determine which toll tag is right for you:
How to Use the FasTrak Flex Toll Tag

Before your trip, set the switch on the toll tag to match the number of people in the vehicle. If you are traveling as a carpool, motorcycle, or eligible CAV*, set the switch to position 2 or position 3+ to signal that you qualify for toll-free or discounted travel in express lanes.

At toll bridges, you must travel in the designated carpool lanes to receive the discounted toll regardless of the switch position.

How to Use the FasTrak CAV Toll Tag

Before your trip, always set the switch on the toll tag to match the number of people in the vehicle. Tolling equipment will automatically recognize and apply any discounts you are eligible for.

At toll bridges, you must travel in the designated carpool lanes to receive the discounted toll regardless of the switch position.

*In the SR-237 express lanes, eligible CAVs do not qualify as a carpool unless they meet the minimum occupancy requirements for a carpool. Drivers must set the switch to position 1 when traveling as a single occupant. We recommend the FasTrak CAV toll tag for eligible CAVs driving in the SR-237 express lanes. Drivers using a FasTrak CAV toll tag will receive a 50% discount when traveling as a single occupant.
†Clean air vehicles are not eligible for reduced tolls and may not use carpool lanes on the Golden Gate Bridge unless they meet the minimum passenger requirements for carpools and have a valid FasTrak toll tag.
