Bay Area Express Lanes

Bay Area Express Lanes ease traffic congestion on Bay Area freeways with a lane especially for carpools, buses, motorcycles and other eligible vehicles. Solo motorists who choose to pay a toll can use Express Lanes, too.

Express Lanes help reduce traffic congestion when large numbers of cars are on Bay Area freeways and highways.

Express Lanes improve the flow of freeway traffic by:

  • Putting more vehicles in the carpool lane
  • Making sure that carpool lanes are used correctly and traffic keeps moving
  • Giving everyone the choice to carpool for free or to pay for a more reliable trip when it really matters
  • Encouraging more carpools, vanpools and buses

Free Rides, FasTrak® & Tolls

Carpools, buses, motorcycles and other eligible vehicles use Express Lanes for free.

Solo motorists who choose to pay a toll can use Express Lanes, too. Overhead electronic signs display the toll rates. As traffic increases, tolls increase. And as traffic decreases, tolls decrease.

To use Express Lanes, grab your Bay Area FasTrak and go.
