How Express Lanes Work
Learn the basics about how Bay Area Express Lanes work. ALL drivers must have FasTrak. Carpools must have FasTrak Flex and eligible Clean Air Vehicles need FasTrak CAV toll tags. All lanes operate 5 AM to 8 PM.
Do I qualify for free or discounted tolls?
See this table for an at-a-glance view of each lane's tolling policies.
Motorcycles, vanpools and 3+ person carpools travel toll free on all Bay Area Express Lanes with a FasTrak Flex toll tag set in the 3+ position. 2+ person carpools pay half-price tolls on I-880, US-101 and SR-237, but travel toll free on the I-680 and I-580 Bay Area Express Lanes. 2-person carpools must use FasTrak Flex toll tags set in the 2 position.
Solo-driver clean air vehicles pay half-price tolls on the I-880, US-101, I-680 and SR-237 express lanes. They travel toll-free on the I-580 express lanes, but eventually solo-driver clean air vehicles will pay half-price tolls on all Bay Area Express Lanes. See "For Clean Air Vehicles."
The price to use the lane goes up or down every few minutes depending on traffic. Learn more
- Signs show one or two destinations and the price to travel to each.
- You are guaranteed that the prices shown when you get in the lane are the maximum you will pay, even if the prices change while you are in the lane.
- Your monthly FasTrak® statement will show the start and end point of each express lane trip and the price you paid.
- View this video about understanding tolls on the I-880 express lanes. Tolls work similarly on the Bay Area Express Lanes.
Bay Area Express Lanes have sections where access into or out of the lane is restricted and sections where it is unrestricted.
Unrestricted sections are marked with dashed lines separating the express lane from regular traffic, and cars can enter or exit the express lanes in these sections.
Restricted sections are marked with double white lines. Crossing double white lines is a traffic violation. If you are in a section with double white lines, highway signs explain where to exit the express lane to access highway exits.
The California Highway Patrol (CHP) performs enforcement for all Bay Area Express Lanes. CHP enforces all laws within the California Vehicle Code while patrolling Bay Area Express Lanes, including:
- Carpool occupancy requirements
- Clean air vehicle requirements
- Proper mounting of valid license plates
- Illegal lane and buffer crossing
- Proper mounting of a valid FasTrak® toll tag
- Proper switch position setting on a FasTrak Flex® toll tag
Express lanes have automated toll enforcement like at Bay Area bridges*. License plate cameras identify vehicles in the express lane without a valid FasTrak® toll tag, and FasTrak sends the registered vehicle owners violation notices for the toll amount and penalties. This helps to make sure express lane users follow the rules.
