Pub. Util. Code, § 5417.5

(a) The commission shall ensure that this chapter is enforced and obeyed, and that violations thereof are promptly prosecuted and that penalty moneys due to the state are recovered and collected, and to this end it may sue in the name of the people of the State of California. Upon the request of the commission, the Attorney General or the district attorney of the proper county or city and county may aid in any investigation, hearing, or trial under this chapter. The Attorney General, a district attorney of the proper county or city and county, or a city attorney may institute and prosecute actions or proceedings for the violation of any law committed in connection with, or arising from, a transaction involving a charter-party carrier of passengers.

(b) For purposes of this section, “peace officer” means a person designated as a peace officer pursuant to Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code.

(c) A peace officer may enforce and assist in the enforcement of Sections 5411 and 5412 resulting from a violation of Section 5371, 5379, 5385, 5385.7, or 5387, or more than one of those sections. A peace officer may additionally enforce and assist in the enforcement of Sections 5411.3 and 5414.5. In any case in which an arrest authorized by this subdivision is made for an offense declared to be a misdemeanor, and the person arrested does not demand to be taken before a magistrate, the arresting peace officer may, instead of taking such person before a magistrate, follow the procedure prescribed by Chapter 5C (commencing with Section 853.5) of Title 3 of Part 2 of the Penal Code. The provisions of that chapter shall thereafter apply with reference to any proceeding based upon the issuance of a citation pursuant to this authority.

(d) The commission shall coordinate enforcement of this section with those peace officers likely to be involved in enforcing this section, including undertaking both of the following:

(1) Educational outreach to promote awareness among those peace officers about the requirements of Sections 5371, 5379, 5385, 5385.7, 5387, 5411, 5411.3, 5412, and 5414.5.

(2) Establishing lines of communication so that the commission is notified if an action is commenced to enforce the requirements of those sections specified in subdivision (c), so that the commission may take appropriate action to enforce the fine and penalty provisions of this article.

(e) The Attorney General, a district attorney of the proper county or city and county, or a city attorney may institute and prosecute actions or proceedings for the violation of any law committed in connection with, or arising from, a transaction involving the transportation of passengers by a charter-party carrier of passengers.
