Cal. Sts. & High. Code § 30918

(a) It is the intent of the Legislature to maintain tolls on all of the bridges specified in Section 30910 at rates sufficient to meet any obligation to the holders of bonds secured by the bridge toll revenues. The authority shall retain authority to set the toll schedule as may be necessary to meet those bond obligations. The authority shall provide at least 30 days’ notice to the transportation policy committee of each house of the Legislature and shall hold a public hearing before adopting a toll schedule reflecting the increased toll rate.
(b) The authority shall increase the toll rates specified in the adopted toll schedule in order to meet its obligations and covenants under any bond resolution or indenture of the authority for any outstanding toll bridge revenue bonds issued by the authority and the requirements of any constituent instruments defining the rights of holders of related obligations of the authority entered into pursuant to Section 5922 of the Government Code and, notwithstanding Section 30887 or subdivision (d) of Section 30916 of this code, or any other law, may increase the toll rates specified in the adopted toll schedule to provide funds for the planning, design, construction, operation, maintenance, repair, replacement, rehabilitation, and seismic retrofit of the state-owned toll bridges specified in Section 30910 of this code, to provide funding to meet the requirements of Sections 30884 and 30911 of this code, and to provide funding to meet the requirements of voter-approved regional measures pursuant to Sections 30914, 30921, and 30923 of this code.
(c) Notwithstanding any other law, the authority’s toll structure for the state-owned toll bridges specified in Section 30910 may vary from bridge to bridge and may include discounts consistent with the following:
1. (1) The authority may include discounts for the following vehicles:
  1. (A) Vehicles classified by the authority as high-occupancy vehicles.
  2. (B) Vehicles that pay for tolls electronically or through other non-cash methods. The authority may charge differential rates based on the chosen method.
2. (2) The authority shall provide a 50-percent discount on the amount of the toll increase approved pursuant to Section 30923 on the second bridge crossing for those commuters using a two-axle vehicle who pay tolls electronically or through other noncash methods and who cross two bridges specified in Section 30910 during commute hours. The authority shall establish reasonable and practical operating rules to implement this paragraph.
(d) If the authority establishes high-occupancy vehicle lane fee discounts or access for vehicles classified by the authority as high-occupancy vehicles for any bridge or segments of a highway that connect to the bridge, the authority shall establish the occupancy requirements that shall apply on each segment of highway that connects with that bridge, in consultation with the department.
(e) All tolls referred to in this section and Sections 30916, 31010, and 31011 may be treated by the authority as a single revenue source for accounting and administrative purposes and for the purposes of any bond indenture or resolution and any agreement entered into pursuant to Section 5922 of the Government Code.
(f) It is the intent of the Legislature that the authority should consider the needs and requirements of both its electronic and cash-paying customers when it designates toll payment options at the toll plazas for the toll bridges under its jurisdiction.
