may either pay using the FasTrak electronic toll collection device, using the license plate tolling program, or via a one time payment online. Effective , the toll rate for passenger cars is $7. During peak traffic hours, carpool vehicles carrying three or more people, clean air vehicles, or motorcycles may pay a discounted toll of $3.50 if they have FasTrak and use the designated carpool lane. Drivers must pay within 48 hours after crossing the bridge or they will be sent a toll violation invoice. No additional fees will be added to the toll violation if it is paid within 21 days. Historical toll rates Crossing the original 1927 bridge required a toll, but tolls were removed soon after the state bought the bridge in 1940. Tolls in 1926 were originally set at $0.60 per car plus $0.10 per passenger. This was reduced in 1938 to $0.45 per car plus $0.05 per passenger. After the state took ownership, tolls were immediately reduced to $0.30 per car. In 1942, tolls were further reduced to $0.25 before being removed in 1945. Tolls were reinstated in 1958 with the completion of the parallel span, set again at $0.25. It was increased to $0.35 in 1970, and then $0.40 in 1978. The basic toll (for automobiles) on the seven state-owned bridges, including the Carquinez Bridge, was raised to $1 by Regional Measure 1, approved by Bay Area voters in 1988. A $1 seismic retrofit surcharge was added in 1998 by the state legislature, originally for eight years, but since then extended to December 2037 (AB1171, October 2001). On March 2, 2004, voters approved Regional Measure 2, raising the toll by another dollar to a total of $3. An additional dollar was added to the toll starting January 1, 2007, to cover cost overruns concerning the replacement of the eastern span. The Metropolitan Transportation Commission, a regional transportation agency, in its capacity as the Bay Area Toll Authority, administers RM1 and RM2 funds, a significant portion of which are allocated to public transit capital improvements and operating subsidies in the transportation corridors served by the bridges. Caltrans administers the "second dollar" seismic surcharge, and receives some of the MTC-administered funds to perform other maintenance work on the bridges. The Bay Area Toll Authority is made up of appointed officials put in place by various city and county governments, and is not subject to direct voter
