Do I need a Fastrak Flex toll tag to use the SR-237 and I-680 sunol express lanes as a carpool?

SR-237 Express Lanes


Yes. A FasTrak Flex or FasTrak CAV toll tag is required to receive carpool discounts in the SR-237 express lanes. To qualify as a carpool, a vehicle must have two or more passengers. Both tags have a three-position switch that must be set in position 2 or position 3+, depending on the number of people in the vehicle. Two-person carpools will receive a 50% discount on the toll. Vehicles with three or more occupants travel toll free.

Solo drivers in eligible clean air vehicles (CAVs) no longer qualify as a carpool in the SR-237 express lanes and must pay a toll. Solo drivers in eligible CAVs will receive a 50% discount on the toll if they use a FasTrak CAV toll tag. The FasTrak CAV toll tag is the only toll tag that will communicate the correct discount toll rate to roadside toll equipment. Single-occupant CAVs using a Standard FasTrak or FasTrak Flex set in position 1 toll tag will be charged the full toll. Single-occupant CAVs using a FasTrak Flex set in position 2 or 3+ may be cited by CHP.

I-680 Sunol Express Lanes


Currently, no. Carpools, vanpools, eligible clean air vehicles, motorcycles and commute buses do not require a FasTrak Flex toll tag to travel toll free in these express lanes. If you have a FasTrak Standard toll tag in your vehicle, it must be placed in your Mylar® bag before travel to avoid toll charges. If you have a FasTrak Flex or FasTrak CAV toll tag in your vehicle, be sure it is set properly to position 2 or position 3+ position when traveling in the I-680 Sunol express lanes.
