Bay Area Express Lanes are specially designated freeway lanes that allow vehicles to pay tolls, pay discounted tolls, or travel toll-free based on the lane’s operating requirements. Tolls increase as traffic increases and decrease as traffic decreases to provide a more reliable trip.
Tolls are posted on overhead signs and collected electronically with a FasTrak® toll tag linked to a pre-funded account. All express lanes allow certain vehicle types to travel toll free or pay reduced tolls. Learn more.
All Bay Area Express Lanes operate 5 a.m. to 8 p.m. Monday through Friday. Outside these hours, express lanes are open to general traffic at no charge and have no requirements for FasTrak® or vehicle occupancy.
In all, the Bay Area has plans for 600 miles of express lanes by 2035.

Details
In the Bay Area, different express lanes may have slightly different layouts, signs, equipment and rules. This drawing provides a starting point to understand the basics. (The specific rules for each express lane are here.)
-
Getting In/Out
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.

Pricing and Signs
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 the zone prices shown when you get in the lane, even if they change down the road.
- Depending on where you get out of the lane and the lane's specific tolling rules, you pay either the top price, the bottom price or a price in between.
- Your monthly FasTrak® statement will show the start and end point of each express lane trip and the price you paid.
- The pricing signs on some express lanes may occasionally display “HOV ONLY” instead of a price. This indicates the lane is too crowded and does not have room for toll-paying vehicles to enter.

Enforcement
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.
