Vehicle Code 22511.58
The DMV shall make any information contained in a physician's certificate supporting a disability of an applicant for disabled person's parking privileges available to a requesting law enforcement agency or agency responsible for the administration and enforcement of parking regulations. Such information shall not be disclosed to private or third-party parking citation processing agencies. Boards established by local authorities may review the requested information. If a finding that the certification is fraudulent or improper is made, the board should send such findings to the DMV for review and investigation.
