CA AB2603

Requires the Public Utilities Commission to establish a telephone service with a designated number for the public to report concerns and complaints about charter-party carriers of passengers, including transportation network companies.

Mandates charter-party carriers include the commission's telephone number on all service contracts after January 1, 2018, and requires app-based carriers notify customers of the number during electronic transactions.

Requires the commission to maintain records of all complaints and establish guidelines distinguishing serious from non-serious concerns, with staff attempting informal resolution of non-serious complaints.

Directs the commission to investigate complaints raising serious concerns and initiate enforcement action for violations of the Passenger Charter-party Carriers' Act or commission rules.

Specifies that no state reimbursement is required because any costs to local agencies result from creation of new crimes, which are exempt from reimbursement under California constitutional provisions.
