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.
