USING CARPOOL LANES
We offer toll discounts to carpools, motorcycles, and eligible Clean Air Vehicles (CAV) during commute hours on all Bay Area toll bridges and toll-free travel in express lanes when using FasTrak correctly.
All Bay Area toll bridges have designated carpool lanes allowing these vehicles to bypass traffic congestion. The number of people needed to be a carpool is posted along the highway carpool lanes. Vanpools also can travel toll-free on both bridges and in Express Lanes. It's easy to join or form a carpool or vanpool.
Bay Area Express Lanes — Toll-Free
Use FasTrak correctly for toll-free travel in Express Lanes as a carpool, motorcycle, or eligible CAV.
In the I-580 and I-680 Contra Costa Express Lanes
You must use the new FasTrak Flex toll tag, set to position (2) or (3+).
In the SR-237 and I-680 Sunol Express Lanes
You do not need a toll tag for toll-free travel as a carpool. If you have a standard FasTrak toll tag, put it into a Mylar bag to avoid detection. If you have a FasTrak Flex toll tag, set it to position (2) or (3+).
