California Code, Streets and Highways Code - SHC § 2119

The State Controller shall not draw his warrant upon the Highway Users Tax Fund in favor of any county or city which has failed to establish any road or street fund as required by law, which has failed to deposit money received from the Highway Users Tax Fund in a separate bank account when required under Section 2118, which has failed, neglected or refused to file any report required by law, showing the amount of money received by such county or city from the Highway Users Tax Fund and the disposition thereof, or which has failed, neglected, or refused to restore any such moneys not expended in conformance with any law or constitutional provision. On satisfactory proof by such county or city to the State Controller of the establishment of such road or street fund, the depositing of money in a separate bank account, the filing of such report, or the restoration of the improperly expended moneys, such warrant shall be issued.

A county or city shall have a reasonable time, after notification from the State Controller, to comply with the provisions of this section.
