Eligible CAVs should use a FasTrak CAV toll tag in the SR-237 express lanes and set the switch to match the number of occupants in the vehicle.
Solo drivers in eligible CAVs do not qualify for toll-free travel. If using a FasTrak CAV toll tag, set the switch to position 1 and receive a 50% discount off the toll. The FasTrak CAV toll tag is the only one that will communicate the discounted toll to roadside equipment. Learn more about the FasTrak CAV here. If using a FasTrak Flex toll tag, the switch must be in position 1 – the full toll will be charged.
Carpools, vanpools, motorcycles and other toll-exempt vehicles may travel toll free, but must use a FasTrak Flex or FasTrak CAV toll tag. Use position 2 if there are two people in the vehicle. Use position 3+ if there are three or more people in the vehicle. Motorcycles should also use position 3+.
You must use a FasTrak Flex toll tag set to position 2 or position 3+.
If you have a FasTrak CAV toll tag, set the switch to match the number of people in the vehicle.
You do not need a toll tag for toll-free travel as a carpool, motorcycle, or eligible CAV.
During commute times, carpools, motorcycles, and eligible clean air vehicles (CAVs)* can receive toll discounts on Bay Area bridges. Carpool hours are posted on roadside signage at each location. You must use the designated carpool lane with a valid FasTrak toll tag to receive the discounted toll rate.
*Clean air vehicles are not eligible for reduced tolls and may not use carpool lanes on the Golden Gate Bridge unless they meet the minimum passenger requirements for carpools and have a valid FasTrak toll tag.
